Slugging is a term coined by K beauty and recently popularized on the social media platform Tiktok. This skincare trend refers to the process of sealing your skin with an occlusive agent – Vaseline, white soft paraffin, or petrolatum. It is touted to keep your skin moisturized and prevent transepidermal water loss.
While this technique has been recently popularized again, dermatologists have been recommending this as the last step in the treatment of severe eczema, sealing in moisturizer and helping to trap in moisture. However, this is not commonly recommended for the facial skin, especially in humid climates like Singapore. Because, the face is usually greasier due to the distribution of oil glands. Applying an occlusive substance like Vaseline if you produce quite a bit of oil or if you have acne, is not a good idea.
The science behind slugging
Petrolatum, the ingredient found in Vaseline, Aquaphor and other topical creams, acts as an occlusive and a skin protectant – which means it prevents transepidermal water loss or evaporation of moisture from the skin.
“The trend of skincare slugging is essentially borne out of moisturising in layers. For example, what dermatologists usually recommend for individuals who suffer from severe body eczema is applying first a ceramide dominant moisturiser, one that is formulated correctly with the lipid ratio, then as a final layer, petroleum jelly. This is to increase the occlusive effect on the skin’s microenvironment and this can actually help to maintain moisture in the topmost layer of the skin.
The Multi-CERAM Cream is a new generation “Smart Moisturiser” formulated as a Prescription Emollient Device. It is formulated with an optimal skin lipid mixture, containing a mixture of plant-derived phytoceramides and synthetic ceramide. Antioxidants that fight skin inflammation are incorporated for optimal treatment of eczema.
However, slugging should be applied with other moisturizers for the best effects. The use of ceramides in moisturisers is crucial in preventing and repairing skin barrier dysfunction. When paired with the process of slugging, it can help to increase absorption of the moisturizer and speed up healing of the skin barrier,” accredited dermatologist, Dr. Teo Wan Lin.
Eczema and dry skin
Eczema is primarily due to a defect in the skin barrier and quite frequently presents as itchy and dry skin. The condition is genetically determined and can be made worse by skin irritants, allergies, environment and stress. In my practice, only ceramide-based moisturisers which focus on restoring the skin barrier are prescribed. Ceramides are lipids that occur naturally on the epidermis and are integral to locking in moisture to the skin and regulating healthy skin barrier function.
In layman terms, you may think of the skin as a protective brick wall, and ceramide being the cement that holds the bricks together and prevents water from seeping through, in order to perform an effective barrier function. Intensive moisturising with ceramide is often recommended through the course of an eczema treatment so as to restore healthy barrier function to the skin. In cases of more severe eczema, wet-wrap therapy, which enhances absorption of topical medications by the skin, may be employed over the topicals and moisturiser applied on to the skin as part of treatment.
Slugging is often recommended as the last step in order to seal in ceramide-based moisturizers for increased absorption and enhanced healing.
Is Vaseline safe to use on skin?
Mineral oils in petroleum jelly or Vaseline are completely safe for skin. As long as it’s approved for cosmetic use, the origins of this mineral oil component is not going to cause any damage to your skin. In fact it’s an effective skin smoothener and can help to prevent water loss to the environment.
Is slugging for everyone?
If you do have oily acne prone skin or active acne we don’t recommend applying a petroleum jelly on your skin. Using occlusives on an acne-prone individual can cause a form of occlusion-type comedogenic acne. Instead, opt for a moisturiser that is either cream, serum or lotion based to hydrate and protect the skin barrier.
In humid, tropical climates like Singapore, skincare slugging can increase the occlusiveness of any product that is applied to the skin. This holds truer still with the wearing of the face mask. Sealing on a layer of Vaseline will increase the comedogenicity of any moisturiser that is potentially applied on your face when it’s applied under occlusion.
Additionally, while it does act as a barrier to trap in moisture from leaving the skin, if applied on unwashed skin, it can also trap in any bad bacteria, dirt and grime – leading to breakouts.
How to do skincare slugging the right way?
Apply a ceramide-based moisturizer on dry, flaky, eczema-prone skin on the body.
Seal the products in with a thick layer of white soft paraffin, Vaseline, or a petrolatum based ointment.
Eczema is the most common skin condition in children we see in our clinic. The persistent itching can result in a disruption of daily activities, and understandably, can cause distress to both the child and the parent.
A dermatologist is a qualified skin specialist who has undergone board certification for diagnosis and treatment of all skin, hair and nail conditions. Pediatric dermatology is the diagnosis and management of common dermatological conditions that occur in childhood.
What are some of the common dermatological conditions that can affect children? In this article, we’re going to focus on the treatment and diagnosis of eczema in children by a pediatric dermatologist.
1. Know the Location and Type of Eczema
First of all, how does a pediatric dermatologist diagnose eczema? The clinical pattern of eczema, is as follows. The commonest type of eczema, is a “dry” type of eczema. It occurs generally over the flexures or the extensors of the elbows and the knees. It can also occur on areas which are a bit more sensitive to friction such as the neck and the back of the ears.
Some individuals may have a form of the disease that occurs around the mouth, known as perioral dermatitis. In children who suffer from facial eczema, it is important to rule out if there is an element of irritant contact dermatitis. Very young children who drool may develop facial eczema due to salivary enzymes that cause skin irritation on contact.
The ‘wet’ type of eczema is also known as exudative or discoid eczema. Discoid refers to “coin-like” referring to the round, well-demarcated lesions of discoid eczema. The diagnosis is sometimes confused with other types of skin diseases, such as skin infections i.e. impetigo is a secondary skin infection of the skin can occur together with eczema, causing pus and yellowish discharge. Discoid eczema is a wet type of eczema that is particularly stubborn and may need treatment with oral steroids together with potent topical steroids.
2. Understand Triggers for Eczema
During your consultation with your pediatric dermatologist, it is important to identify triggers for eczema flares. Some of the common triggers would include dust mite allergies, pet fur, carpets and environmental pollution. Stress can also affect eczema flare ups. A HEPA filter may help remove allergens. Stuffed animals can be washed at high heat, sunned or removed to reduce exposure to house dust mites, a known trigger for eczema.
3. Distinguishing Irritant Contact Dermatitis from Allergic Contact Dermatitis
There are two main types of dermatitis. The first is known as irritant contact dermatitis and the second type is allergic contact dermatitis. The two categories are different, because of the way the skin reacts to environmental exposures. In an individual with irritant contact dermatitis, it is a result of accumulated exposure to a substance that breaks down the skin barrier over time. In an individual with allergic contact dermatitis, the key difference is that it is not due to the accumulated damage on skin due to a caustic substance for example, in soaps, or disinfectants.
Rather because of the individual’s true innate allergy to the substance. This means it doesn’t matter if you’ve used the product once or if it’s your 100th time using it—you will still develop an allergic reaction. In fact each allergic contact dermatitis reaction may become more severe. Is it possible to develop allergic contact dermatitis even if you have previously tolerated the product? The answer is yes.
This is due to a process known as skin sensitization. Over time your body’s immune cells build up a memory to these substances that trigger off an allergic reaction in your skin. Common examples of allergic contact dermatitis would be that induced by metals in the environment. Nickel contact dermatitis is due to the presence of the environmental contaminant nickel, in a lot of metal alloys, for example in costume jewelry. Children can become sensitized to the presence of nickel, if they wear costume jewelry from an early age.
The types of irritant contact dermatitis that we encounter in a dermatologist practice are commonly due to cleansing agents, the use of harsh soaps in individuals who have to do a lot of wet work. Working in the kitchen or doing housework, such as laundry or dishwashing without gloves, predisposes to developing irritant contact dermatitis.
The location of the dermatitis will give us a clue as to the cause of it.
Sodium lauryl sulfate, or SLS for short, when it is present in high concentrations without moisturizers in the cleansing formulation, is a major risk factor for the development of irritant contact dermatitis. Irritant dermatitis can occur on the hand and body parts that come into contact with the irritating substance.
Atopic dermatitis is a type of genetically inherited eczema, these individuals have what we termed the atopic triad, which refers to allergic rhinitis, asthma and eczema. A positive family or personal history of any one of these three conditions is a risk factor for the disease. Individuals who have atopic eczema have a genetic predisposition to defective ceramide production, due to a genetic mutation in the gene known as filaggrin.
4. Pathogenesis of Eczema including bacterial infection
The pathogenesis of eczema is best understood via the brick and mortar module of the skin wall. The bricks represent the individual keratinocytes, which form the barrier against the external environment, and the mortar would be the “cement” that holds the keratinocytes together, providing an effective protective barrier against the environment. Now, this cement, is actually the ceramide that “glues” skin cells together in individuals with atopic eczema. The defect in ceramide production leads to a “leaky” wall, which means that if you are exposed to dust, pet fur or other environmental triggers, your skin is more likely to mount an immune reaction trying to fight off these external triggers.
This immune reaction then causes skin inflammation, which leads to the signs of eczema. Signs that your dermatologist would look out for would include symptoms such as flaking, skin swelling and redness. In discoid eczema, pus formation and skin infection, which manifests with yellow crusts.
The role of bacteria in atopic eczema
Bacteria is usually present in healthy forms on a normal person’s skin. In an individual with atopic eczema or other types of acquired forms of the disease such as irritant contact dermatitis, allergic contact dermatitis, there is a disruption in the skin microbiome.
Microbiome dysbiosis refers to a disruption in the healthy balance of the skin bacteria in eczema patients. What dermatologists know is that there is an increase in the bacteria known as Staphylococcus aureus, which is otherwise harmless on normal person’s skin. However, in diseased patients, this causes a superantigen effect, meaning that on its own, the bacteria drives inflammation.
For this reason, skin infection occurs together with eczema and must be treated with all antibiotics in acute flare-ups of the disease.
General measures that can prevent worsening of skin infection in an individual with dermatitis include gentle effective cleansers, such as the Miel Honey Cleanser with medical grade honey with natural anti-bacterial effects. This helps to restore the skin microbiome.
Patients can consider bleach baths, or in the local Singapore context, the dermatologist usually advises patients to go for a weekly swim, as the chlorine present in pool water can reset the skin bacteria.
The role of food allergy in eczema
Food allergy in adults is extremely uncommon, and especially so as a trigger for eczema. However, in a child under the age of four years old, there are cases where foods can trigger off eczema. In this case, your dermatologist will advise you to keep a food diary, which helps to record the intake of specific foods and find a pattern of what may be causing the disease.
True food allergy, presents with the following symptoms. Eye and lip swelling, difficulty breathing and diarrhea, which occurs within four hours of exposure to the suspected food. It is important to manage this with appropriate appropriate dermatological care.
Investigations for Suspected Food Allergy
Skin prick tests can be performed in suspected cases of food allergy.
Other types of tests that will be useful include the RAST test for food allergy to detect specific serum IgE concentrations. A food challenge, can also be performed to determine if an individual should have a specific allergy to food.
5. Management of Eczema
Your dermatologist will first establish a diagnosis based on the clinical features, the pattern of involvement and determine if there are any environmental factors that are constantly triggering off the eczema.
A strong family history is indicative of a genetic mutation. This means the condition is likely lifelong. However, most patients do not display signs or symptoms of eczema if the condition is well controlled and treated. This is especially true for children under the age of 12, it is very important to get the disease diagnosed and treated. This is because by the time they reach adolescence, oil production begins, they have a good chance of outgrowing their eczema.
Lifestyle Measures to Prevent Eczema
Additionally, lifestyle measures to reduce the environmental triggers can be helpful. The application of moisturizers is important – the gold standard of moisturizer therapy is known as Prescription Emollient Devices (PED). PEDs are not normal moisturizers. The Multi-CERAM cream is a type of PED, the best moisturiser effective for eczema treatment. It has been formulated with the optimal lipid ratio that replicates the natural lipid barrier of the healthy skin. The moisturiser also contains antioxidants anti inflammatory ingredients that help to reduce the inflammation in skin.
The Multi-CERAM moisturiser is formulated as a Prescription Emollient Device (PED), the gold standard in eczema management. Dermatologist formulated to treat eczema, dry sensitive skin and to prevent skin ageing. Botanically derived anti-oxidants to improve the appearance of cellulite. Suitable for face and body.
Steroid Therapy for Eczema
An important point to consider is the use of medications. It is very critical to understand that eczema must be treated with prescription creams i.e. topical steroid creams. These must be used under medical supervision.
Steroid Withdrawal and Steroid Phobia
The phenomenon of steroid withdrawal and steroid phobia are commonly reported in the internet because of a poor understanding of how topical steroids work. Using steroid creams without the supervision of an accredited dermatologist can be dangerous. Inappropriate use of steroid creams can cause skin thinning, ulcers, prolonged redness and broken blood vessels. It can cause tachyphylaxis, whereby the individual develops “resistance” to steroid treatment. This is dangerous because there are a limited number of steroid classes available.
Equally, having steroid phobia, where an individual suffering from the disease refuses treatment with medicated creams such as steroids, can be dangerous. It is important to know that there are steroid-sparing alternatives such as calcineurin inhibitors, tacrolimus (trade name Protopic) or pimecrolimus which do not have steroid thinning side effects but can be more costly. These treatments can also cause burning and irritation of the skin. Consult with your dermatologist to determine if this is the best treatment for your eczema.
Steroid phobia or steroid withdrawal in an individual with eczema can lead to extreme inflammation. Worst cases end up as generalized exfoliative dermatitis, a form of Erythroderma that is potentially life threatening. It is a form of skin failure, which can lead to loss of electrolytes, dysregulation of body temperatures and overall organ failure in extreme cases.
Proactive Management of Eczema
Your dermatologist will advise you how best to control your eczema using a prescribed prescription steroid cream. A common method for long term maintenance is known as proactive management. Proactive management of the disease involves a program whereby the dermatologist instructs you how to cut down the topical steroid strength and frequency of application, in order to prevent flare ups of your condition. Gold standard moisturiser therapy with PEDs, wet occlusion therapy with double pajamas and antihistamines are also essential for management of eczema.

What is teledermatology?
Telemedicine is the practice of using telecommunication technologies to transfer medical information. Information can be shared through audio, visual and data communication. Teledermatology is a subset of telemedicine involving the dermatology specialty, that incorporates healthcare management such as during consultation, diagnoses, treatment and education via an encrypted digital platform.
What are some examples of teledermatology practices?
Teledermatology can be practiced in the following ways: Store and forward (SAF) and real time or interactive teledermatology. A simple example of SAF could be sending an email inquiry with an attached digital image of a lesion to receive advice on how to treat the skin condition. For real time teledermatology, it includes a live video conference between the medical provider and the patient. TWL Specialist Skin & Laser Centre developed a stringent teledermatology protocol incorporating both store and forward as well as real time interactive technology via an encrypted platform.
How is it relevant for me?
Teledermatology has many benefits. First, it is a convenient practice as it does not require both parties to be present at the same location. Some skin conditions require follow up appointments up to two times per week. This can takes up a lot of time. As such, teledermatology can be used to drive down the time and costs required in such follow-up visits.
Teledermatology can also be used to help patients receive a second opinion on their diagnosis to improve accuracy. In the unusual healthcare situation such as that of the COVID-19 Virus currently, the availability of remote consultations will greatly assist in public healthcare needs. Teledermatology enables you to consult with a dermatologist right in the comfort of your home.
Twl Specialist Skin & Laser Centre offers accredited Teledermatology services, via virtual interactive real time technology with our dermatologist. Available as of 1st February 2020, all consultations are also integrated with online pharmacy dispensary services. Delivery to doorstep fulfilment of prescriptions available for local and international patients.
What should I expect from a teledermatology appointment?
1. Book an appointment via our online booking system or call 63550522. Key in a valid email address and phone number which will be the main form of correspondence. You will receive a confirmation of the appointment within 1 working day.
2. A Payment Link will be sent, to be completed for First Consultation/Subsequent Consultation Fees before commencement of consultation.
3. A Post-Payment Secure Process will be communicated to you via email for the subsequent steps which will involve the following:
Filling up of 3 single page forms, submission of required images at least 2 hours before scheduled consultation time with our dermatologist*, a fully encrypted video call saved on our secure patient data base will be conducted.
Subsequent fulfilment of prescription is done by our in-house pharmacy with full courier services to your home.
Eczema is one of the most common skin disorders in infants and children. Apart from dealing with the medical aspect of the disease, affected patients may experience significant psychosocial effects. As such, any eczema treatment needs to be comprehensively managed and best by an accredited dermatologist
Also termed as atopic dermatitis, it is very common in children but may occur at any age.
How does Eczema arise?
Atopic dermatitis or eczema is caused by a complex interaction of genetic and environmental factors including:
Most patients with eczema have a lower amount of filaggrin in the epidermal skin layer., due to mutations in the filaggrin gene. Filaggrin is a structural protein that plays a vital role in normal barrier structure and function. A lack of filaggrin contributes to the development of eczema in several ways.
Filaggrin breaks down into amino acids and protein derivative to form natural moisturizing factors (NMFs) in the outer skin layers. NMFs provide moisture retention, maintain the acidic pH and buffering capacity of the skin barrier and prevent an overgrowth of bacteria.
Inadequate filaggrin would mean a reduced ability to maintain hydration, which can cause xerosis (dry skin), pruritus (itching) and subsequently, eczema. A dysfunction in skin barrier may also allow entry of allergens, leading to an inflammatory response thus causing eczema.
Having an impaired barrier function also causes colonisation of a bacterium called Staphylococcus aureus. Scratching disrupts the skin barrier, thus also leads to the bacteria adhering to the outer skin layers.
The extent of bacterial colonization is associated with the severity of eczema.
Apart from genetic factors, defects in immune pathways are usually observed in patients with eczema. They tend to have high levels Th-2 cells, which contribute to a defective skin barrier. Th-2 cells play an important role in the immune system. A poor skin barrier may mean water is lost from the skin and also allows the penetration of irritants (soap, dirt, detergent) and allergens (pollens, microbes, dust-mites).
There is also an overproduction of cytokines in the body. Cytokines are cell signalling molecules that aid in cell to cell communication. It regulates the movement of cells towards sites of inflammation and infection.
The excessive release of cytokines initiates new responses that eventually leads to inflammation, causing the red, itchy and painful symptoms common in eczema.
Patients also have high levels of an antibody called immunoglobulin E (IgE), which puts them at disposition for hypersensitivity to environmental allergens. Hypersensitivity is when the immune system produces undesirable or detrimental reactions, such as attacking the body’s own cells or tissues instead of protecting them. With elevated IgE levels, it would mean exposure to a certain allergen can causes the immune system to attack the body’s own tissues and therefore skin inflammation that may be observed with eczema patients.
When it comes to eczema treatment, there are 3 main components that target a specific manifestation of the disease. As a chronic, relapsing condition that may flare up at variable intervals, a comprehensive home treatment plan is important for successful management.
Repair & Maintain Healthy Skin Barrier:
Lubrication of the skin is required to maintain skin hydration, commonly known as moisturisation. This helps to alleviate the discomfort that xerosis (dry skin) may bring about.
Patients with eczema should use moisturizers that are fragrance-free and least amount of preservatives, as these are potential irritants.
Topical corticosteroids are the most effective and common form of eczema treatment. Corticosteroids are drugs that mimic cortisol, a hormone found in the body. They work by diminishing inflammation, itching and bacteria colonisation.
This medication can be classified according to its potency, ranging from class VII (low potency) to class I (super potent). Great care must be taken to balance the potency of drug needed for results so as to minimise potential side effects.
Side effects include:
Atrophy (decrease in size or wasting away of a body part/tissue)
Adrenal suppression (body produces lower levels of cortisol)
For moderate to severe eczema conditions, wet wrap therapy can be used with topical steroids and dermatologist-approved moisturisers. After the medication is applied to the affected area, it is wrapped with a few layers of wet gauze, followed by dry gauze. Such therapy reduces itching and inflammation by preventing scratching and improves penetration of corticosteroids.
Topical inhibitors of calcineurin – protein phosphatase associated with activation of the immune system, are newer forms of eczema treatment, which are considered on areas unsuitable for topical steroids (e.g. eyelids) or if other eczema treatment options do not yield results. For example, Pimecrolimus cream and Tacrolimus ointment are calcineurin inhibitors that have demonstrated good efficacy for eczema treatments and do not cause side effects that corticosteroids bring, but have other considerations of use that should be managed with an accredited dermatologist.
Antihistamines are commonly used to treat itching. Even without a significant rash, itching can be present. Oral antihistamines help to reduce the sensation of itching, ideally to decrease scratching and trauma to the skin.
Antibiotic or antifungal medicines are used to treat the infected rash, to reduce the amount of bacterium Staphylococcus aureus. Topical mupirocin is often prescribed to prevent further infection.
Taking care of the skin
Avoid dry skin. Asian skin is more susceptible to being dry. Dry skin can cause itching and scratching. Tips to avoid dry skin:
Moisturize, especially after a bath as evaporation can cause excessive drying. A ceramide-based moisturizer that is suitable for sensitive skin and face could be Radiance Fluide™ Hydrating Emulsionwhich is also infused with skin rejuvenation properties. For intensive replenishment of ceramides (which are naturally found in healthy skin barrier but deficient in diseased skin), a dermatologist-tested moisturiser such as the Multi-CERAM may also be considered.
Bathe with lukewarm water for 10-15 minutes.
Use neutral or weakly acidic pH soap. Consider a mild cleanser that soothes the skin like Le Lait™ Milk Cleanser.
Avoid high ambient temperatures.
Avoid irritants that can cause or aggravate a rash, such as perfumes, scratchy clothing or bedding and sweating.
Formerly known as Besnier prurigo, Eczema — also known as atopic dermatitis — is the most common form of dermatitis. It is categorised as a chronic, itchy skin condition. Eczema is less common in adults and more commonly affects 15–20% of children. It is almost impossible to predict whether the condition of one’s eczema will improve by itself or not in an individual.
Sensitive skin is a condition that persists life-long. In a meta-analysis of over 110,000 subjects, it was found that children who developed atopic dermatitis before the age of 2 had a much lower risk of persistent disease than those who developed eczema later in childhood or during adolescence. 20% of children with eczema still had persistent disease 8 years later. Fewer than 5% had persistent disease 20 years later.
Genetics in Atopic Dermatitis
Since ‘atopic tendency’ such as eczema, asthma and hay fever can be passed down through the family, knowing one’s own family history of asthma, eczema or hay fever is very useful in diagnosing atopic dermatitis in infants. The complex interaction between genetic and environmental factors causes and triggers atopic dermatitis. Defects in skin barrier function make the skin more susceptible to irritation by contact irritants such as soap, the weather, temperature and non-specific triggers.
The appearance of eczema varies from person to person. In acute eczema flares, inflamed, red, sometimes blistered and weepy patches are common. In between such eczema flares, the skin may appear normal or suffer from chronic eczema with dry, thickened and itchy areas. The appearance and feel of eczema varies from one’s ethnic origin, age, types of creams applies, the presence of infection or an additional skin condition. However, there are some general patterns to where the eczema is found on the body according to the age of the affected person.
Atopic Dermatitis Changes with Age
Although eczema can manifest itself in older people for the first time, the onset of eczema is usually seen before a child turns two. It is widely distributed amongst infants less than one-year-old. It is unusual for an infant to be affected with atopic dermatitis before the age of four months. However, they may suffer from infantile seborrhoeic dermatitis or other rashes prior to this.
As infant’s tend to scratch at their itchy skin with their sharp baby nails, the appearance of eczema in infants tend to be usually scaly, dry, and red. The signs of eczema are physically first apparent on cheeks of infants. Due to the moisture retention of nappies, the appearance of eczema in the napkin area is frequently spared. However, just like other babies, if wet or soiled nappies are left on too long, they can develop irritant napkin dermatitis. Although, eczema is often worst between the ages of two and four it usually improves after four and it may clear altogether by the time one enters into teenhood.
As toddlers tend to scratch vigorously at their itchy skins, the appearance of their atopic dermatitis may look very raw and uncomfortable. As they start to move around, the dermatitis tends to become more thickened and localised. Body parts and areas such as the extensor aspects of joints, specifically the elbows, wrists, knees and ankles and even genitals are most commonly affected in this age group. This changes as the child grow older. The pattern frequently shifts from extensor aspects of the joints to the flexor surfaces of the same joints, such as creases. This is when the affected skin often becomes lichenified; thickened and dry from constant rubbing and scratching.
However, the extensor pattern of eczema persists into later childhood in some children. Older school-age children tend to develop a flexural pattern of eczema which commonly affects the elbow and knee creases and other susceptible areas such as the scalp, eyelids, earlobes, and neck. It is possible for school-age children to develop recurrent acute itchy blisters on their palms, fingers and sometimes on the feet, medically known as pompholyx or vesicular hand/foot atopic dermatitis
Many children in this age group tend to develop a ‘nummular’ pattern of atopic dermatitis. This refers to the appearance of small coin-like areas of eczema scattered over the body. Commonly mistaken for a fungal infection such as a ringworm, the appearance of these round patches of eczema are usually red, dry and itchy. Most of the eczema tends to improve during school years and it may completely clear up by the time they reach their teenage years. However it is important to note that the barrier function of the skin is never entirely normal.
The presence of atopic dermatitis in adults are varied in many ways. Despite having a possibility to have a diffused pattern of eczema, eczema in adults is usually more dry and lichenified compared to eczema in children. Eczema is adults are commonly persistent, localised, and possibly confined to the eyelids, nipples, flexure, and hands or all of these areas. Hand dermatitis in adult atopic tends to appear thickened, dry but may also be blistered at the same time. Infections such as staphylococcal infections are both recurrent and a prominent possibility. Occupational irritant contact dermatitis can trigger eczema. This most often affects hands that are regularly exposed to water, detergents and /or solvents.
As eczema can be triggered by physical, environmental and cosmetic factors, particular occupations such as hairdressing, farming, domestic duties, domestic and industrial cleaning and caregiving tend to expose the skin to various irritants and, sometimes, allergens, aggravating eczema. As it is easier to choose a more suitable occupation from the outset than to change it later, tt is wise to bear this in mind when considering career options. Having atopic dermatitis does not exclude contact allergic dermatitis (confirmed by patch tests in children and adults).
It could take many months to years to treat eczema and treatments plans often includes: – Intermittent topical steroids – Reduction of exposure to trigger factors – Ceramide based moisturisers (such as the Multi-CERAM which helps restore healthy skin barrier function) – In some cases, management may also include one of more of the following: – Antibiotics – Antihistamines – Crisabarole ointment – Phototherapy – Topical calcineurin inhibitors, such as pimecrolimus cream or tacrolimus ointment – Oral corticosteroids – Longstanding and severe eczema may be treated with an immunosuppressive agent. – Azathioprine – Ciclosporin – Methotrexate
Clinical trials of biologics such as Dupilumab are promising cures for eczema.
Definitely. If one or more parents suffer from eczema, the child is also more likely to develop the condition.
3. What should parents look for when trying to detect the onset of eczema in children?
Eczema typically starts as an itchy, dry skin condition in the first year of life or later. Parents may notice red, scaly patches occurring on areas such as scalp, face, chin, body, arms, legs or knees. Children may rub themselves against bedding to relieve themselves of the itch. This could be severe because it will interrupt children’s sleep at night.
4. Are food and allergies always linked for eczema in children?
Food does not cause eczema. However, some studies show that children below the age of 4 may find that certain foods worsen the condition of eczema. It is important to consult with your child’s dermatologist before excluding food from your child’s diet as children need a balanced diet . Only children with established food allergies will find that certain food can aggravate their eczema condition.
5. What should children with eczema refrain from doing?
Eczema in children can be especially hard to manage if good habits are not inculcated early on. Instead of scratching, children should be taught to pat their skin. At the same time, they should also keep the skin properly moisturised, keep their fingernails clipped and wear cotton gloves to bed. They should also wear clothing of light, breathable material such as cotton to sleep.
6. How should parents shower their child with eczema?
It’s best to use soap-free cleansers or bath oils. Try to avoid soaps containing sodium laureth sulphate as it contains a lathering agent that can irritate and dry the skin even more. Parents should also avoid abrasive materials such as loofahs or wash clothes.
The shower is preferably kept short, using lukewarm rather than hot water. After the shower, pat the skin dry with a towel and use moisturiser liberally when the skin is slightly damp.
After showering, diligent moisturising with a ceramide-based moisturiser such as the Multi-CERAM is also an important part of eczema management. The skin barrier may be thought of as a brick wall and ceramide, the cement that is sealing in between the bricks that confers a strong barrier function to the wall to prevent water penetration. Diseased eczema skin is often deficient in ceramides, resulting in poor skin barrier function and allowing rapid trans epidermal water loss. Hence, one may see the appearance of dry scaly patches around the diseased areas.
Diligent moisturising with a ceramide moisuriser – i.e. using a thick visible white layer on affected areas several times a day initially, is imperative in any eczema treatment. This is in order to replenish ceramides naturally found in the skin and support restoration of healthy skin barrier function. Healthy skin will in turn kickstart its own production of ceramide which will help to sustain the benefits of intensive ceramide moisturisation initially.
7. When do parents need to bring their child to a dermatologist?
Eczema in children and at any age needs to be treated, ideally by a dermatologist. In the situation when eczema gets out of control, such as when the itch significantly affects the child’s daily activities. If the skin is infected — red with pus oozing out or if the child is unwell — then it will be necessary to seek medical attention.
8. I heard eczema cannot be cured, is that true?
The root cause of eczema in children or adults is in the genetics, which cannot be changed. With better understanding of eczema these days, it can be fully treated and controlled by a dermatologist. Topical steroids are of paramount importance when reducing inflammation caused by eczema.
9. Are there any side effects of steroid treatments?
If steroids they are used inappropriately, they can cause skin thinning, which is cosmetically disfiguring. There is also a phenomenon called tachyphylaxis, which is when normal steroids lose their effects, and stronger steroids are required instead.
However, if you are getting your eczema treated by a qualified medical professional, the correct dose, potency, duration and class of steroid will be given — appropriate to your child’s eczema depending on the location, age group and severity of eczema.
Dr. Teo is an accredited dermatologist at TWL Specialist Skin & Laser Centre who is well-versed with childhood eczema. She has been interviewed on the topic by Singapore magazine, Motherhood, and Singapore news channel, Channel NewsAsia.
