Hormonal Acne – 5 Best Tips from a Dermatologist

June 15, 2020

For many people, blackheads, whiteheads and pimples are a normal part of puberty. However, for some, acne can be a stubborn problem that occurs well beyond their teenage years. This is known as Hormonal Acne. Hormonal acne are characterized by painful and unpleasant pimples. It most commonly appears in adult women ages 20 to 40. In this article, I will be sharing about the science behind hormonal acne and the recommended treatment option.

Dr Teo Wan Lin Singapore Dermatologist Treats Hormonal Acne

Dr. Teo Wan Lin is an accredited dermatologist and an expert on cosmeceutical skincare research and development. She is the author of  “Skincare Bible – Dermatologist’s Tips for Cosmeceutical Skincare”  which was published July 2019 by Barnes & Noble, Baker & Taylor and Apple Books and available in bookstores islandwide from January 2020. She heads up Dr.TWL Dermaceuticals, a specialist cosmeceutical skincare line with evidence-based active ingredients for anti-ageing and skin health. Its subsidiaries, the Pi-Cosmeceutical Custom Makeup Lab and the Conscious Mask Bar are part of the Conscious Concept Pharmacy launched in December 2019, featuring environmentally sustainable makeup and skincare materials. In this article, she shares about hormonal acne.

1. What is hormonal acne?

Hormonal acne is characterised by flare ups during specific periods in the menstrual cycle. Individuals with hormonal acne often present with large painful cysts around the chin and jawline area. Mild hormonal acne is often a normal physiological occurence. However, more severe forms may be directly related to an underlying gynecological problem known as polycystic ovarian syndrome (PCOS). In Polycystic Ovarian Syndrome. Other symptoms may include irregular menstrual cycles, excessive facial hair growth, weight gain in addition to adult acne. 

2. Who suffers from hormonal acne?

Sufferers of hormonal acne tend to be adult females who find that the acne persists beyond puberty. In my knowledge, there has not been any clinical epidemiological study performed by dermatologists on the incidences of hormonal acne. However, in my practice, out of 10 adult women that I see, a good 60 or 70% would report an influence of their menstrual cycle on their acne.

3. When should I see a dermatologist for my hormonal acne?

Finally, at the earliest onset of a flare up consisting of more than 5 pimples a month should warrant a visit to a dermatologist. This is especially if one does not have a history of having acne. The earlier the start of treatment, the lower the chances of morbidity from scarring. Acne has severe psychosocial effects as well. Dermatologists recommend that acne treatment should be commenced earliest as persistent acne flare ups cause emotional distress.

4. What is the best treatment option for hormonal acne?

The best treatment option for hormonal acne  is to first visit an accredited dermatologist. A clinical evaluation will be conducted to inspect for any other clinical signs suggestive of a more severe underlying gynecological issue such as PCOS.  Early detection and concurrent treatment of the underlying PCOS is key to effective control of hormonal acne. 

 The attending dermatologist will subsequently determine the acne treatment regime based on the appearance of the acne itself, rather than on the fact that it is hormonal acne. If it is predominantly nodules and cysts, treatment will likely be escalated to an oral medication isotretinoin (also known as Oratane or Accutane).

However, most hormonal acne patients have moderate severity, comedonal type acne with occasional painful cysts. These individuals start treatment  with an oral contraceptive pill that has cyproterone acetate in addition to the estrogen component. Cyproterone acetate has been proven to block the male hormone testosterone. This is helpful in treating hormonal flare ups of acne. This may also be administered with oral antibiotics which can help reduce inflammation in cases of moderate-severe acne.

Hormonal acne, like other forms of acne, is always treated with topical anti-inflammatory creams in addition to oral medications. An antibacterial cleanser is essential. I have moved away from prescribing chemical antibacterial agents like triclosan to natural derivatives. My patients use a Honey Cleanser Formula made with medical grade honey. Medical grade honey is naturally anti-bacterial and anti-fungal.

Individuals who suffer from extensive comedonal acne around the hairline may actually have concomitant fungal acne- a condition known as Pityosporum Folliculitis. Acne-prone individuals tend to have excess sebum (oil) production, and this also predisposes to increased fungal growth. Malessezia, which is the yeast organism responsible for fungal acne, overgrows in individuals with excess sebum production. This is worsened by humid weather. 

Physical therapies such as blue light and lasers help hormonal acne. Blue light helps to suppress the acne bacteria, propionebacterium acnes which is responsible for acne flare-ups.

Lasers such as the carbon laser are semi-ablative, meaning they do not directly traumatise the surface of the skin but still help to resurface gently. These can also help to control sebum production by directly shrinking oil glands. The results are cumulative, meaning that the more sessions undergone, the greater the effects of sebum reduction. 

In terms of answering your question as to the best treatment option for hormonal acne, it is important to highlight that acne is a medical condition rather than a cosmetic one. It is caused by a myriad of factors working together. Firstly, our personal genetics, the second being inflammation which is influenced by genetics as well.

Hormonal fluctuations in females during the menstrual cycle indicates that certain individuals are more sensitive to circulating amounts of testosterone than others. Hormones trigger off increased oil production- which aggravates acne inflammation. Bacteria also play a role in acne. Individuals with acne have higher counts of propionebacterium acnes. Diet plays a role as well, with dairy products and foods high in saturated fat causing flare-ups of acne. 

With this,  one can then medically target several of these processes in the treatment of hormonal acne. There is no one single method. It has to be addressed holistically. If you have primarily hormonal acne that is caused by PCOS, taking an oral contraceptive pill and treating the underlying hormonal issue would help to resolve the skin problem. However, 80-90% of the adult females I see have a combination of factors causing their acne. We have to approach the treatment holistically, addressing all these processes. 

5. How can I prevent hormonal acne?

Truth is, many individuals are predisposed to developing adult acne because of their genetics. Singapore’s humid climate is not helpful for acne sufferers, as the moist environment encourages growth of bacteria. Secondary skin infections like gram-negative folliculitis cause pustules and inflammation.

From what I observe, most adult acne patients start treatment too late. Prevention is always key. If you have greasy skin or are prone to hormonal flares of acne, a good skincare routine is helpful. For removing all the dirt, grime and makeup, I advocate double-cleansing. This helps overall to reduce the bacteria load your skin. Cleansing encourages a good balance of good bacteria, eliminating bad bacteria on one’s skin.

Individuals who have hormonal acne tend to get gram-negative folliculitis, a secondary bacterial infection caused by bad bacteria on the skin. Using a well formulated anti-acne pimple cream is also important. This helps to treat inflammed papules and can prevent progression to acne cysts. I have moved away from prescribing topical antibiotics (which lead to bacterial resistance with time) to botanical derived anti-inflammatory active ingredients such as Chlorella Vulgaris, an algae extract which directly blocks sebum production. Natural moisturising factors such as amino acids also helps to reduce inflammation. 

Hormonal Acne Dermatologist Honey Cleanser
The Miel Honey™ Cleanser is  made of a blend of nature-derived emulsifiers. It thoroughly cleanses the skin with botanical emulsifiers leaving a clean yet moisturised feel. It contains Arnica Montana Extract which stabilizes skin and reduces flaking. It is also a natural anti-bacterial and anti-fungal active ingredient.

The use of antioxidants serums such as vitamin C reduce bacterial counts and can improve acne as well as acne scars.  I regularly prescribe hyaluronic acid serum which helps to regulate oil production. An underrated active ingredient is polyglutamic acid, an active ingredient which can hold 4-5 times more moisture than hyaluronic acid itself. The Mineral Booster which I formulated for problem-skin has predominant polyglutamic acid content and is very effective for moisturising throughout the day, over/under makeup. It is an excellent humectant with additional natural moisturising factors which enhances the skin’s natural repair barrier without a heavy cream formula which can increase facial oiliness.

 Mineral-Booster Hormonal Acne Dermatologist Skincare
The Mineral Booster contains Polyglutamic Acid holds 4-5 times more moisture than Hyaluronic acid. It is an effective moisturiser for oily, acne-prone skin as it is lightweight while directly hydrating the skin. It prevents reactive seborrhea.
Vita C Serum Hormonal Acne Treatment Dermatologist Skincare
Dr.TWL Vita C GOLD™ Serum is a neutral stabilized form of Vitamin C  which is suitable for individuals with sensitive skin. The potent anti-oxidants reduce activity of acne bacteria and improve scarring.

3 Best Tips to Avoid Acne Breakouts from a Singapore Dermatologist

May 19, 2020

“How do we avoid acne breakouts?” As dermatologists in Singapore, this is the commonest question we get asked. Certainly not a surprise, considering over 90% of the world population is affected by acne at one point or another in their life. Yes, acne is not a problem unique only to Singapore, which has a constantly hot and humid climate that some may try attribute their less-than-ideal complexion to.

Whilst the climate could play a role in proliferation of the P. acnes bacterium responsible for acne breakouts, the underlying cause of it is actually multi-factorial and intertwined with one’s genetics. Given the pervasiveness of acne, there are naturally burning questions surrounding what we can do to get rid of pimples that have popped up and how do we prevent them from reoccurring, which we discuss below.

Pimples that have come to the surface have two possible outcomes. One outcome would be the pimples going away, so the pus and all the debris get extruded out within two to three days. The pimple flattens out and leaves a mark and eventually it fades. The other possible outcome, which is undesirable, would be having the pimple grow bigger and bigger. This becomes cystic acne and may feel as being very deep under the skin. The pimple may also become part of broader acne breakouts, with multiple cysts and may even be painful. It is therefore a no brainer that we want to prevent the second outcome.

The crux here is to understand that having just 1 or 2 pimples a month is classified as physiological acne. This can actually be very well managed with over the counter topical acne creams. However, if you have anything more than five pimples a month, there is a need for prescription medications. Be it in the form of creams or oral medications, because otherwise, you will likely end up in an inefficient cycle, find that the problem keeps recurring and never goes away.

If you have anything more than 5 pimples in a month, it means that under your skin, you have at least 20 pimples gradually rising to the surface. These embedded pimples take turns to come out. That is why some people struggle with having acne which never seems to go away. The pimples do not appear overnight, contrary to popular belief. Micro-comedones, which are little bumps under your skin, rise to the surface of skin through the process of inflammation. These could take 1 to 2 weeks to appear. In the interim, over the counter (OTC) acne medications may be useful in resolving some bumps, especially where there are fewer bumps.

There are plenty of OTC active ingredients we know traditionally for treating acne. These include benzoyl peroxide, salicylic acid, and some people use sulphur based solutions. However, in my opinion, these only work for very mild acne. I personally do not prescribe any of these in my practice anymore, because they cause irritation and very often the side effects outweigh the benefits. Furthermore, you can get a lot of sensitivity, redness, burning and stinging sensations.

If you have more than 5 pimples a month or experience acne breakouts, you have at least moderate to severe acne. This warrants a visit to your dermatologist for comprehensive management of your acne condition. The following are some tips which I would dispense to those having mild acne breakouts, and also applicable as adjuncts during acne treatment and maintenance thereafter.

1. Use anti-inflammatory creams on acne breakouts

In place of the traditional acne treatment ingredients, I am now proposing anti-inflammatory pimple creams that are composed of bioactive viable botanical ingredients. One such cream is the Blemish Spot Cream, which I have formulated using an algae extract and amino acids. This is instead of the traditional harsh chemical ingredients which work by drying out the skin.

With studies in more recent years, we understand more about acne being an inflammatory condition, which is genetically determined. Accordingly, we work towards reducing inflammations. Therefore, certain amino acids like serine and methionine, that help to repair wounds and reduce inflammations, would be effective. If you think of your pimple as an injury to the skin, which it really is, you want the skin to heal faster. By the same principles, the raw materials supporting wound healing, i.e. amino acids, have the effect helping the pimple to resolve.

In addition, lipid extracts from the algae chlorella vulgaris is also a critical anti-inflammatory constituent. A 2015 study showed that these extracts have tremendous efficacy in inhibiting human inflammatory mediators, with nearly 80% inhibition in some permutations, thereby reducing the pathogencity of P. acnes in causing acne breakouts.

Another key ingredient in the Blemish Spot Cream cream tackles oil production. Oil production significantly worsens acne, causing it to become more inflamed. The abundance of oil also becomes a perfect breeding ground for bacteria, to even cause secondary bacterial infections. In this light, we use extracts from the Argania spinosa tree, colloquially known as argan oil, to reduce oil gland activity. Apart from regulating oil production, sterolins (a form of plant fats) in argan oil also has a potent anti-inflammatory effect from dampening overactive antibody immune responses.

Botanical-based anti-inflammatory creams have in fact increasingly taken the place of prescription antibiotic ointments in our practice. You may have heard of clindamycin, clindoxyl and erythromycin gels which are topical antibiotics that kill surface bacteria. The antibiotic gels, however, have demonstrated limited success in suppressing acne inflammation. Furthermore, I think it is important to highlight that these lose efficacy after a maximum of  3 months. This is because the body gradually develops resistance against topical antibiotics and should be closely managed by your dermatologist.

A more sustainable second category of prescription medication would be retinoid creams. Retinoids belong to the vitamin A group of topicals. Different trade names exist, although by and large the mechanism of action is similar. Essentially, retinoids such as tretinoin work by treating the microcomedones under the surface of the skin.

They accelerate the rate of cellular turnover of the skin, thereby bringing up to the surface microcomedonic bumps in the first one to two months of treatment. This is before they start to suppressing the growth of such microcomedones. However, these are not without side effects, such as redness and irritation which may occur during the course of treatment and needs to be monitored by your dermatologist.

For those with mild acne, the potent anti-inflammatory properties of the Blemish Spot Cream will be handy in resolving acne breakouts. This is especially when the pimples are not yet fully inflamed and in clinical practice for such cases, has demonstrated particularly quick spot resolution of comedones. For those undergoing acne treatments or maintenance post treatment, the Blemish Spot Cream may also be used for prevention of acne breakouts around acne-prone areas.

2. Use an anti-bacterial cleanser

I think for acne it is very important that you use an anti-bacterial cleanser. For the ladies, double cleansing works in this method – oil soluble pigments such as those from makeup, especially eyeliner, mascara, eye shadows pigments, need to be dissolved in either a micellar formulation or a oil based emulsion. The oil-in-water emulsion forms a milky formula which is what I usually recommend to my patients because this is much gentler on skin.

The second stage of cleansing is where acne-prone skin would benefit from if done correctly. An anti-bacterial face wash in the past to us meant using a chemical such as triclosan. Triclosan, while effective in preventing acne breakouts, has had some controversy in its use. Although not definite yet, it has some reported effects on the human hormonal system and that is why I have also stopped prescribing that. Instead, we use a medical grade honey cleanser which helps to emulsify the grim, dirt, and it forms a foam which is not based off a very strong lathering agent like the laureth sulphates.

Anti Acne Breakouts Dermatologist Honey Cleanser

We are using the natural emulsifying lathering properties of honey and the same would go with a product such as soya. The great things about these natural emulsifiers is that they form a layer of what we call a humectant after you wash it off. This is so that while your skin feels clean after a wash, it is not dehydrated. The humectant layer in fact stays on the rest of the day and helps to form a healthy skin barrier between your skin and the environment to help prevent the onset of acne breakouts. 

3. Healthy diets go a long way to prevent acne breakouts

The other aspect that should not be neglected would be your diet. I find that if you have problem skin and we start you on treatment, almost everybody will get well as long as they comply with treatment. However, the rate of recovery as well as the sustainability of the positive effects of treatment is significantly better in the group where they are conscientious with their diet.

We now know that diets high in trans fat, i.e. deep fried foods, dairy products, sugary foods, are pro-inflammatory which means that it can exacerbate your underlying acne conditions to cause acne breakouts. I tell my patients to stay away from that and also take an anti-oxidant rich diet. It is very hard to imagine that we are not what we eat. The same goes for skin, an organ that needs to be respected along with whatever nutrition that goes to your skin, which occurs via 2 ways.

Firstly, nutrition to the skin is topically applied and to me that is the most significant such as in the form of antioxidant cosmeceuticals. The second means, by consumption, is for the healthy functioning of all your tissues. This is for it to fight the daily assaults of free radical formation from environmental pollution, uv exposure, biological ageing. It is critical that have your supply of anti-oxidants in diet and all these do not have to be found in supplements which may be controversial, in terms of the amounts that have to be ingested in a sustainable manner.

We should perhaps instead look towards a healthy natural anti-oxidant rich diet. Do include lots of blueberries and even olive oil. Olive oil in our diet has been proven both by cardiologists as well as within the dermatology research community to have positive anti-ageing effects on the heart as well as on the skin. These factors do add up eventually for healthy skin that is free of acne breakouts.

The 1 Best Acne Treatment According to a Dermatologist — What’s in your pimple cream? 

April 4, 2020

 

Acne in teenagers and adults is a troubling condition, affecting one’s self-esteem and confidence levels. In my clinical practice as a dermatologist, acne vulgaris, colloquially known also as pimples, forms at least 50% of the daily load of patients I see. There are many aspects to be addressed within the dermatology consultation.

This varies from the cause of pimples, to questions about effective acne treatments, DIY formulas, over the counter acne creams and prescription medications. I have sought to share as many of these treatment pearls in the following article as comprehensively as possible, and hope it can help shed some light on the best acne treatments available. 

Best Acne Treatment - Dr Teo Wan Lin Dermatologist

Dr. Teo Wan Lin is an accredited dermatologist and an expert on cosmeceutical skincare research and development. She is the author of  “Skincare Bible – Dermatologist’s Tips for Cosmeceutical Skincare”  which was published July 2019 by leading bookstores Barnes & Noble, Baker & Taylor and Apple Books and available in bookstores islandwide from January 2020. She is the founder of Dr.TWL Dermaceuticals, a specialist cosmeceutical skincare line with evidence-based active ingredients for anti-ageing and skin health. Dr. TWL Pharmacy is the only full fledged online specialist dermatologist compounding pharmacy in Singapore and is jointly headed by a trained pharmaceutical engineer for strict quality controls.

Why do pimples form and what exactly is happening to your skin when a pimple forms

Pimples is the colloquial term for Acne Vulgaris. This refers to an inflammatory condition of the skin that presents with blackheads and whiteheads, otherwise known as closed comedones and open comedones respectively, inflamed papules as well as acne cysts. The cause of Acne Vulgaris is multifactorial.

First of all, it is determined by one’s genetics. Individuals with a family history of acne tend to have a higher chance of developing acne. This is brought on by the onset of puberty which leads to the secretion of the male hormone, testosterone. Testosterone, in turn triggers oil production in both men and women. That being said, sebum, the oily substance secreted by your sebaceous glands, is essential for the entire process of acne formation.

The third thing that occurs due to one’s genetics, is the process of inflammation itself which leads to comedone formation. All pimples whether whiteheads or blackheads arise first as microcomedones under the surface of the skin.

When they reach the surface of the skin, they become visible. The process that drives this is a mix of genetics, the presence of sebum as well as some form of dysregulation of the process of follicular keratinisation i.e. the way your skin retains dead skin cells around your skin pores.

Aside from genetics, there is also the involvement of a bacterium known as Propionibacterium acnes – a heavy commencer in individuals who suffer from acne. Finally, a lot of acne flare-ups can be due to the secondary bacterial infection of existing acne bumps known as gram-negative folliculitis. This tends to present with pus-filled papules and tend to have a yellowish tip.

I have observed that I always get acne in the same spot

While I do hear this coming from my patients quite often, i.e. “I always get this one pimple now and then on my cheek, chin, forehead…”, there is no scientific answer to this. From my personal experience, this could be due to one of the following. Firstly, if you tend to pick at your pimples, there is a condition known as acné excoriée. The entire name of this condition in french is acné excoriée des jeunes filles meaning acne excoriée of young girls.

There is an element of this compulsive picking of acne and this is the main reason why I find my patients having acne at the same spot. They constantly pick at it so even when it is healing, it does not get the chance to heal and picking introduces secondary bacterial infection.

The second reason why is because you are suffering from some form of acne that is related to occlusion. Some people wear helmets or face masks. If acne develops around that area, it is a type of acne known as occlusion acne. It could also be due to the application of comedogenic, hair waxes etc.

The third thing, if you are talking specifically about acne on the chin, you have to consider perhaps it is not acne at all. There is a condition known as perioral dermatitis. Perioral dermatitis looks very similar to acne and if you are seeing a non-specialist, it is very easy to be confused. This is because the bumps look very similar to acne, except that it is a mixture of eczema and inflammation, acne bumps, or it could even be acne rosacea. 

All about Acne Creams

When you apply a pimple-clearing product to your pimple, what happens to the spot? What are some of the ingredients that you’d want to look out for in a pimple product, and what should you avoid? Are pimple drying lotions ok for the skin and how do they work?

If you find yourself searching online for answers to these questions, you are not alone. These are some frequently asked questions by sufferers of acne and I shall seek to clarify them here. There are a few categories of pimple-clearing creams. The first being the good old-fashioned creams that simply dry out the skin and reduce sebum production. 

Pimple Drying Medications

This category would include topicals that contain the following active ingredients: benzoyl peroxide, salicylic acid, calamine lotion, sulfur-containing lotions. In some mild cases these creams may lead to an improvement in acne itself.

Pimple Creams Containing Antibiotics

The second category of acne treatment creams would be those containing antibiotics. The commonest antibiotic-acne gels would be those which contain clindamycin or erythromycin as an active ingredient.

These work on the premise that a lot of cystic acne is caused by secondary bacterial inflammation. As with all topically applied antibiotics especially in a chronic skin condition like acne which is not primarily due to skin infection, there is a huge problem with using topical antibiotics.

Topical antibiotics work well in a short-term simply because the skin has never been exposed to it. But very quickly the body learns to identify the antibiotic and develops resistance.

This is particularly concerning because the resistance doesn’t just take place in the skin level. Exposure of the topical antibiotics on the skin level leads to resistance systemically as well. For example, it could lead to antibiotic resistance when one is older.

The main thing about antibiotics is that it is a mere short-term fix and does not work after some time. There are other combinations of antibiotic gels, such as clindamycin combined with benzoyl peroxide which is the active ingredient present in the OXY pimple cream. The benzoyl peroxide component has been proven to reduce the emergence of bacterial resistance. 

Prevention Creams – Retinoids for Acne Treatment of Whiteheads and Blackheads

The third category of pimple creams which I consider more preventive rather than treatment sort of cream is the retinoid category. These are the vitamin A derivative creams. We have heard of creams like tretinoin and adapalene which may have differing trade names. Both these creams are Vitamin A derivatives and they work via preventing microcomedone formation.

However, when you apply these creams, you should not apply it to inflamed active pimples as this can worsen the inflammation process. Rather they should be used in conjunction with active acne treatments prescribed by a dermatologist which is proportionate to the severity of your acne as preventive treatment. When you start applying a  retinoid cream for example, you only get to see the result 2-3 weeks later. 

A Dermatologist’s Recommendation of the Ideal Pimple Cream – New Generation Anti-Inflammatory, Anti-Sebum Pimple Creams

The fourth category of acne treatment creams is actually what I actively advocate now and which we have formulated in a highly effective Blemish Spot Cream under Dr.TWL Dermaceuticals. It is targeted at reducing inflammation itself. I am very convinced that botanicals have a prominent role to play in cosmeceuticals.

Cosmeceuticals are no longer just confined to the realm of having anti-ageing properties but are also adjuncts for the treatment of many medical skin conditions. I have used botanicals extracts successfully in the treatment of rosacea for example.

For acne, I incorporate an algae extract from chlorella vulgaris which actively reduces the oil gland activity. This is combined with amino acids such as methionine and serine that help to heal the skin when you apply it. The main thing is that when you try to dry up an active pimple, very often you get more inflammation as you are burning the skin around it.

What you need to do is to try to get the pimple to heal as quickly as possible. This is so that you minimise the risk of scarring. At the same time, this also treats the underlying problem of acne pimples which keep forming.

A post shared by Dr.TWL Dermaceuticals (@drtwlderma) on

Are there different pimple creams best suited for the different types of acne (eg blackheads whiteheads, red swollen pimples)?

For tretinoin and adapalene which are the two main available form of vitamin A creams, these should not be used for red, painful, swollen acne treatment. They are best suited for comedonal acne which would be your blackheads and your whiteheads. For drying pimple creams, like benzoyl peroxide, salicylic acid, calamine lotion, I don’t recommend applying these to areas that have broken skin.

If you apply these to broken skin, the irritation and drying potential is just going to be multiplied. Potentially, you are going to end up with something that looks like a chemical burn. That is something much redder with a lot of peeling flaking and bad scarring.

Instead, I would recommend using an anti-inflammatory product with botanical-based extract that doesn’t contain anything irritating like salicylic acid. For example, the one we use is based on an algae. There is no issue applying this over areas with broken skin, although it also really depends on the formulation itself.

In addition, for a correctly labelled and medicated acne cream, i.e. not just a cosmetic product, there would be very clear indications of use available. 

Does my skin ever get used to pimple-clearing products – is that why my pimple never seems to heal?

If you are using a medication like clindamycin and erythromycin, then yes because you develop real bacterial resistance which stops the medication from working. If you are using something which is drying such as the first category I spoke about earlier, or something anti-inflammatory, there is no evidence that your skin can actually develop a form of resistance to that. It is simply that the severity of acne has progressed or in the first place it wasn’t sufficient acne treatment. 

Adult Acne Treatment

For patients with mild acne, they will have approximately 3-5 pimples every month and they tend to be of the teenager age group. Once you are past your teenage years, from the age of 21 onwards, it is a different ballgame of what dermatologists term as adult acne. If you still suffer from acne then, meaning having an average of more than 5 pimples every month after the age of 18, it is at the minimum, a case of moderate acne.

Moderate severity acne means that while you don’t have severe scarring or cystic acne, it is still very persistent and would need to be treated medically by an accredited dermatologist. In my clinical experience, moderate acne does not respond well to topicals only regimens. Topicals are only useful as an adjunct in the treatment of moderate acne.

On the other hand, using appropriate cleansers and pimple-clearing gels works well and is sufficient for mild acne. It may be a selection bias by default, given that attendances at a dermatologist practice would be moderate cases.

This is because the mild cases perhaps get treated at the GP level before they do get to us. Moderate cases of adult acne would need more treatment than just topicals. According to international dermatology guidelines, there are two options for the treatment of adult cystic acne.

Oral Acne Treatments

Firstly, the oral pathway for which I must emphasise that there are many oral medications that are safe and effective that have been widely prescribed by dermatologists internationally for decades. Examples of commonly prescribed medications include low dose oral antibiotics like doxycycline, erythromycin. These function primarily as anti-inflammatory medications to prevent comedone formation.

Minocycline is less frequently used these few years as it has been linked to a few rare cases of hypersensitivity syndrome, on top of potentially causing blue-grey skin discolouration.

Erythromycin in particular is safe for pregnant and lactating individuals. Oral contraceptive pills such as Diane-35 and Estelle-35 contains estrogen as well as cyproterone, which blocks androgen (testosterone activity). Androgens are male hormones that trigger off oil production, exacerbating adult hormonal acne.

Women with a history of irregular menstrual periods with cystic acne may have undiagnosed polycystic ovarian syndrome (PCOS). Such individuals will benefit from joint management of a dermatologist and a gynaecologist. Treatment of PCOS is with hormonal therapy, which will benefit adult acne treatment as well as preventing infertility.

Non-Oral Acne Treatments and Physical Therapies

Secondly, we have the non-oral pathway for acne treatment which involves physical therapies that have to be administered in a clinic setting. For example the usage of LED wavelengths, blue-light, two times a week for one month.

Blue light is therapeutic for treating acne that is especially worsened by the bacteria Propionebacterium Acnes. This has been proven to be effective in a regimen of twice weekly 30 minutes duration for a one month regimen. 

Chemical Peels and Lasers for Acne Treatment – Can they be used independently?

Use of chemical peels and specific lasers like the carbon laser helps to shrink the oil glands of someone with active acne, especially in individuals that may not want to go on oral medications.

I always recommend those with persistent moderate acne to go for a short course of a safe antibiotic such as erythromycin or doxycycline in conjunction with any of these physical therapies. This is the most cost-effective option that targets inflammation that goes on in acne rather than blindly treating it from the surface.

What about Isotretinoin for Cystic Acne

For severe acne, you may suffer from deep painful cysts which often involve pus and bleeding and there will be a lot of scarring. The treatment for this is very straightforward, our first line is always this medication called isotretinoin.

The medication is also known as accutane or oratane which are brand names of the forms of isotretinoin available. Isotretinoin is an extremely effective oral medication which works essentially by shrinking your oil glands.

Without oil, your skin simply doesn’t produce acne. However, isotretinoin use does come with drawbacks like increased sun sensitivity, dryness of the lips and eyes. One also has to monitor your liver function and cholesterol levels whilst on isotretinoin.

Time taken by Acne to heal with a pimple cream

A lot of patients in my practice have asked me to gauge the number of days to determine if an acne product works and my answer is simply this. 

The Wound Healing Process of a Pimple’s Life Cycle

When a pimple forms it is best viewed as an injury caused by inflammation to the skin. You may go by the principles of wound-healing, especially when it only involves the top two layers of the skin (the epidermis and dermis).

Within the first 2-3 days of a cyst, there should be signs of pus draining. Should there be blood coming out of it, soon one should observe the redness and swelling resolving as well.

Acne That Does Not Heal

Acne may progressively accumulate and get larger instead of reducing in size. For example, the acne may get more painful, accumulate more pus and blood that doesn’t seem to be draining. When this occurs, one has to consider that there is an underlying cyst forming. 

What is An Acne Cyst?

The formation of an acne cyst involves the collection of haemoserous material – blood, sebum, dead skin, keratin and debris. These substances subsequently get “cordoned off” by the body with a wall around it. This is part of the immune system’s response to inflammation. Acne cysts do not respond well to any topical treatment.

Proper Treatment of An Acne Cyst

Acne treatment of cysts involves a combination of the following. Firstly, an injection known as an intralesional steroid injection helps to reduce inflammation locally. It is injected right into the centre of the nodule and within 3 days, swelling will reduce the underlying swelling.

It is very important for the injection to be administered. This is because untreated acne cysts can lead to more severe problems like facial abscesses with drainage of pus.

Furthermore, it can spread to other parts of your face which is rare but has been documented. Concurrently, large painful acne cysts should be treated with an oral antibiotic such as amoxicillin, sufficient to treat the secondary bacterial infection that causes this reaction.

In the light of the Covid lockdown, our clinic is open to TeleDermatology services for acne treatment. This includes complimentary doorstep courier of prescription, contactless delivery within 3 working days. Same day delivery can also be arranged.

If you suffer from mild to moderate acne, you may try these over the counter cosmeceuticals proven for acne treatment.

Chemical Peel In Singapore – Dermatologist’s Best Tips

A post shared by Teo Wan Lin (@drteowanlin) on

Dr. Teo Wan Lin is an accredited dermatologist and an expert on cosmeceutical skincare research and development. She is the author of  “Skincare Bible – Dermatologist’s Tips for Cosmeceutical Skincare”  which was published July 2019 by leading bookstores Barnes & Noble, Baker & Taylor and Apple Books and available in bookstores islandwide from January 2020. She is the founder of Dr.TWL Dermaceuticals, a specialist cosmeceutical skincare line with evidence-based active ingredients for anti-ageing and skin health. Dr. TWL Pharmacy is the only full fledged online specialist dermatologist compounding pharmacy in Singapore and is jointly headed by a trained pharmaceutical engineer for strict quality controls. In this series “Dermatologist Talks” she shares her top tips on common skincare topics. In this article, she talks about chemical peels, are they necessary and are there any alternatives for those who wish to do it at home? 

What is a chemical peel?

A chemical peel is the application of a high yet safe concentration of a certain acid on the skin. Superficial peels involve the use of acids such as  salicylic acid and glycolic acid. They induce epidermal injury and the induced exfoliation is followed by dermal and epidermal regeneration from adjacent epithelium and skin adnexa, which results in improved surface texture and appearance of the skin. Superficial peels are most commonly used for mild skin disorders such as dyschromia, acne, postinflammatory hyperpigmentation, melasma, and actinic keratosis.

What are the benefits of a chemical peel?

Chemical peels exfoliate the dead outer layer of your skin and are mainly used to treat:

  1. Acne (i.e Blackheads, whiteheads & pimples)

Chemical peels reduce inflamed lesions, loosen and reduce open and closed comedones (colloquially known as blackheads and whiteheads respectively). Chemical peels also lighten mild acne and facial scars from past blemishes. It can be used to compliment topical or oral medication to treat pimples and control acne breakouts. 

  1. Wrinkles

Reduce fine lines under eyes, around the mouth and on the forehead. 

  1. Facial scars 

Lighten mild acne and facial scars.

  1. Pigmentation

Reduce age spots, freckles, and dark patches (melasma) due to pregnancy or taking birth control pills. 

  1. Sun-damaged skin

Remove the sun-damaged outer layers, leaving you with smoother skin.

Chemical peels also increase the absorption of skincare products into the skin because the removal of the topmost layer of skin ensures that there are no dead cells impeding the penetration of products.

SA has anti-inflammatory, antimicrobial and depigmenting properties. It is safe in skin of all Fitzpatrick phototypes. Because of SA’s lipophilic and comedolytic effects, it is particularly effective for comedonal acne. 

What are the side effects of a chemical peel?

The side effects of the treatment tend to be mild and temporary. Most side effects subside after 3 days.

  • Stinging
  • Skin peeling
  • Redness
  • Scabbing of the skin (due to skin cells being removed)
  • Increased sensitivity to the sun

How is a chemical peel performed at your clinic?

A certified nurse will hand you a consent form for the chemical peel before proceeding to explain in detail what you can expect during the peel and the benefits. The peels we use in our clinic are: Lactic Acid, Salicylic Acid and Glycolic Acid. Before the procedure, your face will be cleansed and eye protection like goggles or gauze may be applied. During chemical peel, the nurse will use a cotton pad or brush to apply the chemical solution to your face. You may feel a slight stinging sensation however the nurse will assess the skin and monitor the reaction to the acid. Once complete, the chemical solution will be removed or a neutralizing solution will be added. The strength and peel times are tailored to individual patients skin type and needs. After the peel, we will apply AMINO ACID 360° MASQUE  and leave it on for 10 minutes to soothe the skin. It contains a potent concoction of skin brightening Vitamin C which soothes inflamed acne and lightens scars. LARECEA™  Extract with lifting amino acids penetrate the epidermis to stimulate collagen regeneration, resulting in all round 360 degrees lifting effect for a youthful, smooth contour of face.

Looking Your Best – 3 Tips for Clear Skin and Healthy Hair From A Singapore Dermatologist 

March 23, 2020

1. Keep your skin acne and blemish free

Acne occurs when the oil glands under the skin, scientifically known as sebaceous glands, become clogged with sebum, an oily substance. This process is known as inflammation, and it is often genetically determined. Hence, if you have a family history of acne, you are at high risk.

A normal amount of sebum usually keeps the skin healthy. Your oil glands become active once you reach adolescence due to hormones and this is when acne usually starts. When clogged, bacteria grows in the glands. This leads to swelling, bumps and visible blackheads and whiteheads on the skin’s surface.

Acne can still affect adults. In fact, many adult females suffer from acne breakouts around the chin, especially during certain times of their menstrual cycle. This should be differentiated from other conditions such as perioral dermatitis, which may look similar but is treated differently.

Under proper dermatologist care, acne can be fully treated with the correct medications, creams and light treatments. For patients who prefer not to be on oral medications, some forms of laser therapies  are safe and effective acne treatment methods too. Blue light, a type of light therapy is designed to treat acne when it is active by killing Propionebacterium Acnes on the skin, which causes acne inflammation. Non ablative and ablative resurfacing lasers can treat subsequent acne scarring after it subsides.

In addition to treatment, prevention against future acne breakouts are also crucial. Diet and proper skincare are also important factors in contributing to one’s acne condition. Therefore, holistic counselling with specific advice about how to manage your condition is important.

For mild to moderate acne, you may consider over the counter dermatologist formulated cosmeceuticals such as the Anti-Acne Bundle here.

Anti Acne Bundle for Clear Skin

2. Use hair regrowth products

Originally prescribed only in my dermatologist practice, the Copper Peptide Hair Regrowth Serum uniquely contains Copper tripeptide, a novel molecule that stimulates hair growth. Clinically proven to have similar efficacy to that of 5% minoxidil, stimulating growth without irritation side effects or toxicity. Studies show collagen production is increased, strengthening existing hair and thickening the hair shaft.  

In conjunction with the hair serum, one can consider cosmetic camouflage for a quick fix.  I often recommend the Kerabuilt Follicle Hair Fibres, integrated with Biomimetic Hair Technology for natural-looking, instant results. In addition, it is chemical-free and hypoallergenic, recommended even for those with hair loss and sensitive scalps.  

In my dermatology practice, almost all patients suffering from hair loss had also done their due research online about possible causes of hair loss before seeing me. The real problem though, medical websites are not written for the layperson and the lists of diagnoses of conditions that lead to hair loss simply leave the hair loss sufferer worried and fearful. Those that do their research on forums and beauty websites are none the wiser, as they suggest many non-evidenced backed methods of hair growth or causes of hair loss which is simply unscientific and wrong information.

There are many different causes of hair loss, which can occur at the same time or individually, and dermatologists are best positioned conduct a thorough history taking, medical evaluation/examination and may recommend blood tests and other tests before diagnosing the cause of hair loss. For some rare causes of hair loss, especially of what is termed scarring alopecia, a scalp biopsy, which is where samples of the scalp are taken for microscopic examination may be required.

3. Consult a dermatologist for scarring on the skin

Treatment of scars on one’s skin can be in the form of chemical peels or lasers, which can be both ablative and non-ablative. Your dermatologist will advise which treatment option is best suited for your skin. In the meantime, a good concealer consists of a colour corrector. Orange is well suited to conceal dark scars and pigmentation whereas green conceals redness. Follow up with a CC cream with cosmeceutical active ingredients to treat and conceal your blemishes at the same time – achieving an overall even complexion.

How a Singapore Dermatologist treats Blackheads

In this series “Dermatologist Talks” she shares her top tips on common skincare topics. In this article, she shares about the importance of taking care of your neck area.

 

Treatment of Blackheads

  1. How do I get rid of blackheads?

First and foremost, it is important to know what blackheads are and how they arise. Blackheads, the colloquial term for open comedones, are a type of acne caused by an overproduction of oil, and tend to cluster around areas like the nose. The buildup of keratin and oil around the follicle is oxidised and turns blackish because the oil itself is oxidised by air.

Open comedones are best treated with:

  • A mixture of chemical peels, containing salicylic acid, lactic and glycolic acids to control the oil production.
  • Carbon laser peels to help shrink oil glands and reduce production of oil.
  • Prescription creams, containing tretinoin, that accelerate skin regeneration.
  • Oral medication will be necessary for acne, and a medication known as isotretinoin, may be prescribed to help to shrink your oil glands, which has to be taken under close medical supervision.

I do not recommend manual extractions as they can cause more inflammation, infections, and scarring. I personally treat both open and closed (whiteheads) comedones using a specialised machine with a vacuum handpiece that gently extracts blackheads and whiteheads without pain or scarring, at the same time infusing a customised blend of fruit-based acids that exfoliate the skin. Last year, we launched the Dr.TWL SilkPeel Home Medi-Facial Kit with our biomaterials team.

A post shared by Dr.TWL Dermaceuticals (@drtwlderma) on

The device basically combines the microdermabrasion benefits that we use in our clinic with a very gentle chemical peel effect to increase the absorption of the cosmeceuticals. This allows for the physical removal of the debris from both open and closed comedones (ie. Blackheads and whiteheads), reducing the appearance of blackheads and preventing subsequent formation.

  1. How do I reduce the formation of blackheads?

A good cleanser is important. For cleansers, look for the labels ‘’dermatologist-tested and formulated’’ for maximum clinical efficacy. I personally use a cleanser based on medical-grade honey which I have partnered with a laboratory to formulate, it effectively cleanses away dirt, bacteria and grime, as honey is a naturally derived emulsifier, unlike chemical lathering agents, and also possesses antibacterial properties, without stripping away the skin’s natural oils. Overall, a good cleanser should leave the skin feeling clean (not squeaky clean though as this usually means overcleansing) and also still soft and moisturised. It’s a misconception to go for really ‘strong’ harsh cleansers because it generally strips the skin of all moisture with strong lathering agents like SLS (Sodium Laureth Sulfate) leaving the skin red and flaky while the acne problem doesn’t go away.

  1. Do over-the-counter treatments work?

Nothing over the counter actually works well.

Pore strips help to physically remove the bits of keratin and oxidised oil but it tends to accumulate again and the problem recurs.

Products which contain salicylic acid usually have too low concentrations to be actually effective and higher concentrations can cause irritation.

Beware of traditional facial blotters to remove oil because it can cause the skin to paradoxically feel ‘dehydrated’ and the oil glands to produce even more oil to compensate. For patients with greasy skin in the day , it may help to just wash the grease off with a good cleanser rather than keep blotting. Either that, or use a fragrance/alcohol-free baby wipe to wipe off the grease before touching up makeup.

  1. How often should I go for treatments?

It depends on your skin condition. We recommend patients to firstly get their skin condition properly diagnosed by an accredited dermatologist, who would then subsequently recommend a regimen most suitable for them.

The Dangers of Dealing with Blackheads yourself

  1. Can you extract them at home?

Never pick your pimples or squeeze your blackheads (or whiteheads) as the bacteria on your fingers will cause infection, subsequently causing inflammation which may result in the formation of cystic acne.

Cystic acne is a severe form of acne which warrants specialist dermatologist care as it can leave terrible scars and can be secondarily infected leading to cysts and abscesses (collections of pus under the skin) if left untreated. See a dermatologist early, you definitely need oral medication and also may need a stronger form of anti-acne medication known as isotretinoin which helps to shrink your oil glands. Isotretinoin has to be taken under close medical supervision as it can have side effects on one’s liver and cholesterol levels.

Do not use scrubs with rough beady material as these only irritate the skin further besides being totally ineffective at removing blackheads, whiteheads and definitely can worsen cystic acne. Persistent acne is not normal and should be treated by an accredited dermatologist to avoid infections and scarring.

  1. What happens if you leave them be? Will they form pimples?

If you leave them alone, there is a chance of secondary infection in which these blackheads develop into active pimples. Otherwise, they remain as black dots on the skin which may be rather unsightly.

  1. Some people think by putting toner, you close the pores. Is this true? 

Toners with an alcohol base as an astringent draws water and oil out via an osmotic difference.  They may provide symptomatic relief right after application, where the skin feels dried up instantaneously and the appearance of blackheads is subdued due to the temporary removal of debris. However, over time, I find that this gives rise to a condition known as reactive seborrhea. The skin being subjected to these harsh agents, decides that it is dehydrated and paradoxically, produces even more oil. Hence, I did not include any toners in the skincare regimen I designed. Instead, my recommendation for people with oily, acne-prone skin with blackheads is the Miel Honey™ Cleanser: a very effective anti-bacterial, anti-grease cleanser which also leaves a moisturising barrier. Medical-grade honey has a humectant property, meaning it is able to trap water underneath the skin. Additionally, we developed a specialised type of blotting paper for people with severely oily skin to help with the removal of oily patches throughout the course of the day. Our Anti-Inflammatory Oil Blotting Linen contains an extract of Cannabis Sativa which helps to restore the skin barrier when it comes into contact with the skin’s oil. This is unlike traditional blotters which dehydrate the skin causing it to produce even more oil. Finally, the use of a very lightweight moisturiser throughout the day, such as our Mineral Booster™, helps to restore the natural equilibrium of the skin with the environment. Overall, I find this cosmeceutical regimen is more sustainable for someone who is looking to reduce the production of oil and the appearance of blackheads, especially when used in combination with topical prescriptive items.

Top 5 Harmful Chemicals in Your Makeup and Other Beauty Products

October 15, 2019

Skin irritation? Breakouts? Allergies? Think it may be due to bad diet and unhealthy lifestyle? Or maybe because of your dirty beddings or perhaps pollution? All of that may be possible contributors to your unlikely skin concerns but have you ever wondered that maybe the problem could be in the makeup that you use?

 

 

Makeup is all fun and games until you learn about the risk it comes with using them. If using makeup products is part of your daily routine, then it is important to know about what you put on your skin! Did you know that the average woman ingests about 6 tons of lipstick in her lifetime? You may not notice because you don’t literally eat your lipstick, but every time lipstick gets unto your teeth, or whenever it transfers on to your food when you eat, the main thing is it’s now down your tummy! So before anything else, it’s now time to question on whether or not the products that you use are safe for you.

You may be reading the ingredient list of your makeup products but do you think that’s all it is? Some companies hide “certain substances” or mask it under deceptive titles. Others may have listed them, but what’s lacking is that there is not enough information on the potential harm it may cause for their consumers.

 Certain ingredients used in the production of makeup and cosmetics can cause more harm than benefits and these can cause problems that may put your health at serious risk. Issues related to the use of products with these harmful ingredients may associate with skin allergies, cancer, weakened immunity, and more.

“For patients who suffer from sensitive skin and allergies, it’s often a vicious cycle with makeup products which are used for concealing the skin imperfections, and the same preservatives and ingredients in these products cause an exacerbation of the underlying skin condition,” says accredited dermatologist Dr. Teo Wan Lin.

How about for those without skin problems? Dr. Teo says, “Makeup is in direct contact with skin, and as skincare can deliver benefits to skin via topical absorption, makeup can also be used as a means to improve the health of the skin when it is incorporated with cosmeceutical active ingredients as an anti-ageing formula— while at the same time offering concealing of imperfections, which can improve individuals’ self-esteem. For products applied to mucosal areas such as the eyes and lips, it’s worthwhile to switch to pure mineral colorants in cosmeceutical bases because these are sensitive areas that are prone to irritation, and have thinner skin that will cause any harmful substances to be directly absorbed.”

 We have listed down below the Top 5 harmful chemicals that are used in the production, preservation, and manufacturing of makeup products that you may be using everyday. Guess what, these ingredients don’t have to be present in your makeup— if you switch to mineral makeup for the eyes and lips!

 

 1. Phthalates

 This chemical is most commonly found in perfumes, colour cosmetics, nail polish, and hair care products. Phthalates are linked to endocrine disruption, developmental and reproductive toxicity, and cancer. Phthalates may be labeled as phthalate, DEP, DBP, DEHP and “fragrance”. Some companies intentionally exclude this on their ingredients list. Products that list “fragrance” on the label should be avoided to prevent possible exposure to phthalates.

2. Paraben

Paraben…paraben… One of the most famous ingredients for makeup. Though you may not know much about this chemical, you’ve probably heard about this already because you may have previously encountered the term “paraben-free” on some beauty products and wonder what does it mean. Parabens are preservatives used in a wide variety of personal care products and foods to prevent the growth of microbes. Parabens are not water soluble and can penetrate the skin. As a result, repeated application of a product or multiple products containing parabens could mean almost continuous exposure. These endocrine-disrupting chemicals can be absorbed through skin, blood and the digestive system.

Effect of Paraben: causes endocrine dysfunction, interferes with male reproductive functions, and can lead to rapid skin ageing and DNA damage.

 Paraben may be labeled as ethylparaben, butylparaben, methylparaben, propylparaben, isobutylparaben, isopropylparaben, and other ingredients ending in –paraben.

3. Lead

Lead has continuously been a very controversial component of lipstick. But did you know that it is often used in makeup foundation and whitening toothpaste as well? High levels of lead may pose a very serious risk on our health and studies have shown that there is no safe amount of lead exposure as though even at small amounts, lead can be very dangerous. Medical experts are clear that any level of lead exposure is unhealthy. The FDA or Food and Drug Administration has been determined to limit the usage of lead in lipstick and in a variety of other cosmetics. Read here.

 Exposure to lead has been linked to a host of health concerns:

  • Neurotoxicity: It has been linked to learning, language and behavioral problems.
  • Reduced fertility in both men and women
  • Hormonal changes and menstrual irregularities
  • Delayed onset of puberty in girls and development of testes in boys.

References:

http://www.safecosmetics.org/get-the-facts/regulations/us-laws/lead-in-lipstick/

 

4. Asbestos

 Talc is used as an ingredient in face powders, blush, and eyeshadows. The incorporation of asbestos in talc is due to poor regulations involving cosmetic-grade talc, which is also known as talcum powder. Talc and asbestos are minerals that form together. That means talc mined for commercial uses can be contaminated with asbestos — a known cause of lung cancer and mesothelioma. Before purchasing any product that has talc, make sure it is labeled as asbestos-free. Health concerns of asbestos may include skin irritation, cancer, organ system toxicity.

References:

https://www.asbestos.com/products/makeup/

http://www.safecosmetics.org/get-the-facts/chemicals-of-concern/talc/

 

5. Butylated Compounds (BHA, BHT)

 Mainly used for preservation of our beauty products and personal care products such as moisturizer, lip products, hair products, makeup, sunscreen, antiperspirant/deodorant, fragrance, creams. Butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) are chemicals are linked to several health concerns including endocrine disruption and organ-system toxicity.

Don’t get fooled by this because butylated compounds are also used as preservatives in food like meats, sausage, poultry, baked goods, beer, etc.

We have no control over the ingredients or manufacturing of the mass market makeup available in the market, but is that where custom blend mineral makeup can perhaps fill a need? “Custom blend mineral makeup has its advantages especially for eye and lip makeup because pure minerals are utilised. The eyelid and lip area are high-risk locations and naturally have thinner and more sensitive type of skin—known as mucosal skin. “ says Dr. Teo, who remarks that she has been seeing an increasing number of patients in her practice with eyelid and lip eczema, often triggered by makeup products such as mascara, eyelash extensions and lipsticks.

Especially if the sources are clearly labelled and audited, the risk of manufacturing contamination for sensitive products such as lipsticks and eye shadows, which is of the highest concerns to regulatory authorities like the FDA and HSA as well, due to the risk of ingestion and absorption, is eliminated. “When produced in smaller batches, custom blended mineral makeup is preservative free and avoids the problems of lead contamination in mass market manufacturing, which is important in lip products because of the lead content which is inevitably ingested.” Dr. Teo says.

How does one avoid getting these toxic chemicals incorporated into your daily routine? Also, isn’t it time that skincare is infused into makeup, since both are applied for long hours on the skin? Head over here to get your hands on cosmeceutical make-up.

Dermatologist’s Best Guide on Polyhydroxy Acid (PHA)

June 13, 2019

Is PHA (polyhydroxy acid) suitable for all skin types? How does it compare to AHAs and BHAs?

Polyhydroxy acids encompass gluconolactone and lactobionic acids. It has been reported in medical papers as early as 2004 to be effective and better tolerated by sensitive, aging skin.

PHAs works similarly to AHAs by causing the dead skin cells (keratinocytes) to shed at a higher rate, causing reduction in skin irregularities such as uneven pigmentation and texture. In addition, they fulfil the same function of allowing cosmeceutical ingredients such as hyaluronic acid and vitamin C serums to penetrate deeper into the skin.

Is there a possibility of suffering from a chemical burn using skincare products that contain PHA?

PHAs are not as commonly used as AHAs and BHAs, especially as chemical peels in dermatologists’ office setting mainly because the depth of penetration and effectiveness may be less. However, in skincare, the medical literature seems to report that it is a much gentler and moisturising type of chemical exfoliant than the other acids present in skincare, which translates into a much lower risk of skin irritation. In fact, PHAs are large molecules which function as humectants meaning that they trap water under the skin, prevent trans-epidermal water loss and have moisturising properties.

Is there one form of PHA that’s stronger than the others? eg. Lactobionic acid vs Gluconolactone  

Clinical studies to date have grouped the use of gluconolactone and lactobionic acids under PHAs which differ from glycolic acids in the fact that they have a larger molecular structure, penetrate the dermis less and hence is less irritating in addition to having humectant (moisture trapping) properties. I am unaware of any head-to-head study which show whether one form of PHA is stronger than the other.

When should I use PHA? Should I use it in the toner, serum, moisturiser, or cleanser step?

The use of PHAs in skincare has been well-reported to have good exfoliating effects but without the irritation that glycolic (AHA) or salicylic acids (BHA) have. However, I generally do not put in chemical exfoliants in skincare because there is always a risk of skin becoming sensitive after being exposed to it on a daily basis.

There are some studies indicating that compared to glycolic acids which are incorporated in several brands of skincare, those which incorporate PHA are much more suited for people with sensitive, eczema skin. However, I would not prescribe that for my patients with eczema and rosacea in the first place due to the risk of irritation.

What should I be looking out for when I use PHAs?

I would say PHAs seem to be rather novel because it’s a term that hasn’t been used in the recent times but our knowledge of it has stemmed since the 1970s and clinical studies have been done with it since 2004. I think it’s important to prioritise, so the main concern really would be to ask yourself what your skin concern is. If it is anti-aging, then chemical exfoliation itself is not going to give you a miracle result.

Chemical exfoliation can be achieved with glycolic acids, BHAs and in this case PHAs may have the same function but with reduced skin irritation. However, chemical peels alone do not satisfactorily target all skin aging concerns, which lasers in combination with a good cosmeceutical regimen can achieve. It is important to caution that while all anti-aging treatments are aimed at increasing collagen production in the skin, an accredited dermatologist still needs to access the individuals’ problems and side effects before recommending combination treatment.

PHAs should be used in conjunction with cosmeceutical ingredients such as vitamin C as well as phyto which are plant-derived antioxidants that have been proven to fight free radical damage which is the key process in anti-aging. Nevertheless, PHAs are a beneficial form of chemical exfoliation and should be placed in the same category as the use of AHAs and BHAs in chemical peels.

One more thing to add, the clinical results in terms of the depth of skin penetration are likely to be less with PHAs. For patients with other forms of skin concerns, for example acne, they may still find that glycolic acid is much more effective in reducing oil control. If their concern is a medical condition like eczema and rosacea, then certainly I would recommend not using any form of chemical exfoliant at all and rather get treated by a dermatologist.

Facial Exfoliation – Dermatologists’ 1 Best Tip

January 20, 2019

Exfoliation, or the removal of dead skin cells from the outermost layer of the skin, is an important and necessary part of any skincare routine. However, if the word ‘exfoliation’ conjures up to you the action of scrubbing your face with harsh granules, you may be doing more harm to your skin than good.

So what is the right exfoliation technique for your skin?

Benefits of Facial Exfoliation

We shed dead skin cells naturally as new skin cells slowly travel up from the deepest skin layers to the surface. On average, this process takes about 27 days.  As we age, this cell turnover process slows down.

When we exfoliate, we remove the build-up of dead skin cells. Regular exfoliation can reveal younger, brighter skin with an even tone. 

Facial Exfoliation Best Dermatologist Tips

Types of Facial Exfoliation

Exfoliation can happen in two forms: physical and chemical.

Physical Facial Exfoliation:

Physical exfoliation relies on the rubbing of tiny granules or particles over the face to remove dead skin cells by physical force.

While this kind of exfoliation can leave you feeling refreshed, the technique can be too harsh for the skin, especially for individuals with acne-prone or sensitive skin. Physical exfoliation may even weaken the skin’s barrier function and leave your skin red or irritated.

For those of you without sensitive or acne-prone skin, physical exfoliation can still be an option. However, make sure to look out for exfoliating agents that are not too large.

Chemical Facial Exfoliation:

Chemical exfoliation relies on fruit enzymes and gentle acids to slough off dead skin. This mechanism is much gentler than physical exfoliation and more suitable for acne-prone and sensitive skin types.

Types of acids for chemical facial exfoliation

The two most well-known type of exfoliating acids is alpha hydroxy acids (AHA) and beta hydroxy acids (BHA).

AHAs: Alpha hydroxy acids work by causing skin cells to detach from the outermost layer of skin, making them easier to slough off. Once the dead skin cells are removed, new cells can rise to the surface.

Common AHAs used as chemical exfoliants are lactic, glycolic and mandelic acid.

Glycolic acid: Glycolic acid is the strongest AHA as it has the smallest AHA molecule. As such, it is able to penetrate deeper into the skin and can exfoliate at lower concentrations compared to other acids. However, if you are just beginning to try out chemical exfoliants, a different acid should be considered.

Lactic acid: Apart from exfoliating, lactic acid also moisturizes. Individuals with dry skin can consider lactic acid for this dual function.

Mandelic acid: With a larger molecular structure, mandelic acid is not able to penetrate deeply into the skin. This makes it a gentle AHA and safe to use, especially for people with sensitive skin.

BHAs: Beta hydroxyl acids (BHAs) differ from other AHAs as they are oil-soluble. This property allows them to penetrate deeper into our skin and pores.

BHAs exfoliate by softening the outermost layer of skin cells and dissolving unwanted skin debris. They also have anti-inflammatory and antibacterial properties, making them ideal for individuals with oily and acne-prone skin.

Chemical peels for facial exfoliation

Chemical peels are often done at a dermatologist’s office where the chemical agent used can be much more concentrated. Glycolic, lactic or salicylic acid is commonly used. A certified dermatologist is best able to identify the type of peel for your skin.

With regular use, these treatments exfoliate the surface skin and improve fine lines, wrinkles, skin discolouration and texture.

Chemical facial exfoliation at home

Most patients prefer to do chemical exfoliation on their own. However, this can cause skin sensitivity and redness for certain individuals over time without proper medical supervision.

As a result, Dr Teo Wan Lin, an accredited dermatologist at TWL Specialist Skin & Laser Centre, recommends using active ingredients such as stabilised vitamin C (sodium ascorbyl phosphate), hyaluronic acid, phyto plant extracts or LARECEA™ extract. These ingredients are proven to deliver health to your skin without the sensitivity that AHA or BHA might cause when used without medical supervision.

Over facial exfoliation – what happens if you over exfoliate?

The benefits of chemical exfoliation may make it tempting to use AHAs and BHAs often. However, too much exfoliation can disrupt your skin barrier and cause the skin to become red and inflamed. Some encounter a form skin burns when dabbling into prescription type chemical exfoliators, whilst others may even develop eczema of the facial skin due to repeated unsupervised repeated exfoliations.

If you are a beginner to AHA and BHA, start slow with low doses. If you do not have sensitive skin, you may consider exfoliating every week with mild home use agents. Those with sensitive skin should not attempt self exfoliations. Discuss with your dermatologist to have your underlying skin condition resolved first before thinking how often you should get chemical peels or exfoliations.

How bad does your skin react to alcohol?

What happens to your skin when you drink too much?

To maintain the health of your skin, you may want to think twice before you reach for one too many drinks. Alcohol can be pretty harsh on the skin.

Here’s why.

Premature ageing

When broken down, alcohol produces molecules called aldehydes. Such molecules cause damage to the body’s cells by destroying their ability to function. When cells are damaged or die, our body produces new cells to replace them. However, a single exposure to alcohol can reduce the body’s ability to multiply cells.

Another effect of alcohol is the widening of small blood vessels in the skin. This allows more blood to flow closer to the skin’s surface, which produces the distinctive flush and feeling of warmth often associated with alcohol consumption. Over time, this can cause an unhealthy appearance including dullness, enlarged pores, sagging, discoloration and a lack of skin resilience. Such effects can last for days.

Excessive alcohol consumption can further limit the liver’s ability to remove toxins, which can also make you look older.

Dehydration

Alcohol interferes with the body’s ability to regulate water levels. Your brain produces a hormone called anti-diuretic hormone (ADH) that acts on our kidneys to control the amount of water secreted in your urine. When your body is dehydrated, your brain sends a signal to pump out ADH. ADH stops you from urinating as much, allowing you to retain your water levels.

Alcohol inhibits ADH levels. So even when you drink a lot of water alongside your alcoholic drinks, your body only hangs on to about a third of it while the rest goes out in your urine. In other words, alcohol increases urine volume and leaves your body dehydrated.

This dehydrating effect worsens skin elasticity, thickness and density. It also makes wrinkles and fine lines more noticeable. 

Itchy skin

Most itchy skin diseases are exacerbated by alcohol consumption. Alcohol causes eczema to be twice as common, likely due to its suppressive effects on the immune system.

Alcohol also makes psoriasis harder to treat. Psoriasis refers to the condition of red, itchy skin. While alcohol itself does not cause psoriasis, it increases the body’s susceptibility to infection and exacerbates the condition. Heavy drinkers are also more resistant to therapy.

Flushing and Rosacea

Flushing is a common after-effect of drinking and tends to go away the next day. It is more prevalent in individuals who do not have an enzyme that breaks down aldehyde. (Alcohol is broken down via two general steps, first into aldehydes and then to acetate.) An accumulation of aldehydes causes flushing and rapid heart rates.

An impaired alcohol metabolism can also worsen rosacea, a common skin disease with a tendency to blush or flush more easily than others. It can further cause an increased incidence of telangiectasia or the appearance of spider veins at the surface of the skin. 

Inflammation

When alcohol is broken down in the body, reactive oxygen species (ROS) is released as a by-product. ROS are important signalling molecules in the body.

However, excess ROS production can be harmful to the skin as it alters the body’s immune response, triggers inflammation and causes the body to attack itself. This can compromise the skin’s wound healing processes.

Consequently, alcohol can cause skin conditions such as eczema, psoriasis or, in some cases, acne to take much longer to heal than before.

Resveratrol in red wine

Resveratrol is an antioxidant often found in red wine. (Antioxidants work to fight against the oxidative stress that your skin cells encounter.) Resveratrol also has therapeutic benefits against various skin disorders and protects the skin against harmful UV rays. Given that UV radiation is a major cause of ageing, resveratrol is popular for its anti-ageing abilities.

However, there are other ways to get resveratrol that do not include the harmful effects of alcohol.

For a dermatologist-formulated anti-ageing serum, go for Elixir-V™ Total Recovery Serum. It contains a potent concoction of resveratrol, hyaluronic acid and oligopeptides that work together to give you the perfect V-face look.

Seek for professional help

If your skin condition worsens, schedule a visit with a dermatologist as soon as you can. The dermatologist can determine the best course of action and suitable treatment that would be effective for your condition and your lifestyle.
