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 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 featuring environmentally sustainable makeup and skincare materials. 


1. What are the benefits of BOTOX?

Botulinum toxin therapy functions to diminish signs of aging and to treat hyperhidrosis— a medical condition characterised by excessive sweating.

  • Frown lines between the eyebrows.
  • Fine lines and wrinkles around the eye i.e Crow’s feet.
  • Excessive sweating in the underarms when treatment applied to the skin does not work well enough.


2. Can BOTOX be used to treat excessive sweating? 

BOTOX can be used as a treatment for a condition known as hyperhidrosis whereby the body produces excessive amount of sweat under normal environmental temperatures. It is predominantly injected over areas such as the face, underarms and palms. Speak to your dermatologist to find out if you are a candidate for BOTOX used to treat hyperhidrosis.

3. Is it mandatory to consult a dermatologist to undergo BOTOX?

The success of a cosmetic treatment is dependent on the skill and knowledge of the person performing the treatment. Board-certified dermatologists receive many years of education and training, which gives them expertise in this area. During the first consultation, Dr. Teo will inform you if the procedure will deliver the desired results, based on the condition of your skin as well as your age and health.

A medical license is required to purchase Botulinum Toxin. Products you can purchase online without a license are illegal and potentially dangerous. They differ greatly from products used by a dermatologist. Using online products may result in severe complications. Cases of long-term muscle paralysis, Bell’s palsy, and permanent eye damage are just a few examples

4. What occurs during the procedure at TWL?  

A consultation with our accredited dermatologist will determine if you are a suitable candidate for BOTOX. Full financial counselling is provided and informed consent is taken before the nurse prepares you for the procedure. Numbing cream is then applied to the areas where Botulinum Toxin will be injected. The procedure itself takes about 10-15 minutes depending on the number of injected sites. Thereafter a cooling lifting mask is applied to ensure optimal healing. 

When treating fine lines and wrinkles, the dermatologist injects botulinum toxin into targeted muscles on the face or neck. This temporarily relaxes the targeted muscles, causing fine lines and wrinkles to diminish. The effect lasts about 3 to 4 months — and sometimes longer.

When treating excessive sweating, a dermatologist injects directly into the skin on the underarm. A single treatment can provide up to 6 months of relief from excessive sweating. 

5. Are there any risks and/or side effects of BOTOX?

The side effects of the treatment tend to be mild and temporary. Bruising of injection sites may occur. If this happens, the bruising lasts about 1 week.

After receiving injections, people have experienced:

  • Swelling
  • Redness
  • Soreness
  • Bruising
  • Mild headache (uncommon)
  • Weakness in a neighbouring muscle, leading to a temporarily droopy brow or eyelid (rare)
  • Signs and symptoms of botulism, including problems breathing, swallowing, or speaking (very rare)


6. Will I lack facial expressions after treatment? Will it “freeze my face”?

Skilled injectors will ensure that the correct amount of toxin, proportionate to the severity of the wrinkles, is injected to avoid having the frozen face look. 

7. At what age can I start the treatment? Is BOTOX suitable for me? 

Aging is assessed based on the staging on the Glogau Photo-damage Classification Scale. Typically anyone beyond the age of 25 will start to show signs of aging and will hence be a suitable candidate. 

8. How often do I have to return for treatments?

The effects of the treatment last about 3 to 4 months — and sometimes longer. 

9. How soon will I see the results of the treatment?

Majority of my patients see results within 3 to 7 days.

10. Are there any alternatives to BOTOX? 

If you do not have time to visit a dermatologist for your BOTOX procedure, consider these home aesthetic treatments with cosmeceuticals that can help you. 

Dr. TWL’s Oligopeptide vegetal capsules contain argireline. With its clinically proven anti-aging properties, our Oligopeptide capsules relaxes facial tension lines resulting in less noticeable fine lines and wrinkles making it an alternative to BOTOX therapy.

Why Your Dermatologist Would Recommend Soft tissue fillers

October 3, 2017
Soft Tissue Fillers by Singapore Dermatologist

What are soft tissue fillers?

Soft tissue fillers are injectables that aim to reduce wrinkles, hollows, and furrows or “plump up” or the skin to give the skin a smoother and more pleasing appearance. Derived from either natural or synthetic substance, these fillers are effective at contouring specific areas of the face, such as around the lips and mouth, and correcting depressions and scars.

Who are soft tissue fillers for?

Each filler product is designed for different purposes and effects. For those looking to correct wrinkles, enhance their lips through volume augmentation, correct thin, superficial lines around the eyes, mouth and forehead area, looking to contour the areas around their chin and cheeks area and correct deep folds, soft tissue fillers are an effective treatment method.

What should I know about soft tissue fillers?

Soft tissue fillers come in two forms — natural and synthetic. Synthetic fillers are often a popular choice as they produce immediate results and have a lasting effect in comparison to natural fillers. This is because synthetic fillers are derived from animal and non-animal stabilised hyaluronic acid complex. The sugar chains in these complex are often stabilised for a longer period of time, resulting a lasting effect on the skin when treated with soft tissue fillers. As soft tissue filler are able to create volume for wrinkle, facial folds, lips and lines treatments, you are able to see immediate results.

What are the side effects of soft tissue fillers?

With recent technological breakthroughs, new synthetic and natural filler substances have been created to reduce side effects such as allergic reactions, redness and occasional bruising, swelling, itching, minor lumps, or tenderness which usually resolves quickly. However that being said, one should be wary of the mentioned side effects and consult a dermatologist immediately.

What to expect from the treatment?

The duration of the treatment usually lasts nothing more than 30 minutes. Prior to the procedure, nerve blocks and local anesthetic creams could be used to minimize discomfort occurring during the procedure. An accredited and trained dermatologist will examine your face and then determine an exact location to inject the fillers to achieve optimal results.

Depending on the areas that are being treated, the depth of the lines, the condition of the skin and the lifestyle of the individual, soft tissue fillers can last up to approximately one year. For optimal results, patients may get their fillers topped up every six to nine months, or an alternative combination regime involving lasers can be discussed with your dermatologist for maintenance. Cosmeceuticals may also be used as adjuncts to maximise the benefits from filler procedures. Hyaluronic Acid for example, apart from being a constituent of fillers, can also be used in a topical form to enhance hydration and plumping effects on skin.

Botox Treatment Simplified by a Dermatologist

September 25, 2017
Botox Treatments by Dermatologist

Botox treatments were originally introduced as medical treatments for muscle spasticity such as cerebral palsy, some forms of headaches and reducing excessive localised sweating in the armpits. The treatment has come a long way since in making an impressionable mark in the beauty industry.

Botox are now a highly sought after, non-invasive and successful medical treatment for those looking to erase those wrinkles or facial lines for the quick dip into the fountain of youth. With rapid advancements in medical technology since the 2000s, there is no reason the late Joan Rivers or well renowned fashion designer Donatella Versace should scare you when it comes to botox.

Let’s face it, aging is both biological and environmental but fret not, there is something we can now do about our laugh lines, crows feet at eyes or scowl lines on your forehead from the constant smiling, squinting and frowning we subject our faces to. A botox treatment could very well be the solution to all of your worrisome lines. By blocking the signals from the nerves to the muscles, your wrinkles and facial lines tend to relax and soften, giving you a smooth finish. For a youthful glow, discuss with your dermatologist for botox treatments combined with suitable lasers and cosmeceutical skincare.

Side effects of botox treatment

However, to avoid common and significant complications such as ptosis — the drooping of eyelids — or to reduce side effects such as headaches and bruisings, it is advised that you visit an accredited dermatologist (find an accredited Singapore dermatologist here) instead of cosmetologists and aesthetic clinics for your botox treatments.

For a safer and more natural result, opt for a dermatologist who specialises in both medical and cosmetic dermatology. Caveats? Ladies who are expecting and are currently breastfeeding or those with certain medical conditions, botox is inadvisable. Otherwise, it’s the perfect go-to treatment for a fresher renewed look with minimal downtime and quick results.

BOTOX Treatments – A Wrinkle-Free Solution

May 12, 2017

By Dr. Teo Wan Lin, Consultant Dermatologist at TWL Specialist Skin & Laser Centre

Botox Treatments by Singapore Dermatologist

What is BOTOX?

BOTOX is short for botulinum toxin, a medical treatment for facial wrinkles and lines. Originally introduced to treat muscle spasms, further clinical studies have shown that BOTOX treatments reduce wrinkling over the treated muscle.

How does BOTOX work?

BOTOX is a neuromuscular blocking agent that causes the injected muscle to be relaxed by restricting the release of the neurotransmitter acetylcholine. Without this “chemical messenger”, the muscle has no instruction, limiting its ability to contract when we make facial expressions. Thus, the lines that normally result from the contraction of these muscles cannot form, effectively preventing the onset of wrinkles. Given that BOTOX treatments are localized (ie. it only affects the muscle that receives an injection), treatment is always targetted and will not affect the other muscles on the patient’s face and body.

How are BOTOX treatments administered?

Tiny quantities of the toxin will be injected by the dermatologist using a fine needle into the affected muscles. It usually takes three to five small injections to treat a frown line. The injection is almost painless—in fact, most merely describe it as a little pinch.

For more sensitive patients, local anesthesia can be administered prior to BOTOX treatments in order to prevent pain.

What can patients expect after BOTOX treatments?

Most patients do not experience any side effects from the use of BOTOX. However, some patients may experience a mild headache immediately after treatment, which can be treated easily through the use of paracetamol. There may also be slight bruising at the injection area—which can easily be covered by makeup.

Over the week following treatment, patients may also notice that they no longer contract the affected muscles when they frown. This is perfectly normal—it indicates that the treatment is taking effect.

The effect of BOTOX starts wearing off within a few weeks but another dose of it is not needed until three to six months after, where expression lines will return. Another dose will then be required to maintain the effect of BOTOX.

The effect of subsequent BOTOX treatments will typically last longer than the previous, allowing for more sporadic BOTOX treatments to maintain the same, desirable effect it has on a patient’s skin. Eventually, some patients may even be able to maintain the same effect without BOTOX treatment. This can happen because prolonged use of BOTOX has enabled them to break the bad habit that led to the frowning or squinting in the first place.

In addition, cosmeceuticals containing bioactive ingredients such as oligopeptides that stimulate collagen growth, may be used as adjuncts to maximise the benefit from BOTOX. For example, the Radiance Fluide Hydrating Emulsion and Elixir-V Recovery Serum, contain oligopeptides and potent antioxidant plant extracts which augment the anti-aging effects.

Is BOTOX for everyone?

BOTOX has the same efficacy, no matter of your gender and race. However, BOTOX is not recommended for certain groups of people, such as for women during pregnancy or breastfeeding, as well as those with certain neurological conditions such as motor neuron disease or myasthenia gravis.
