Common Skincare Myths Revealed by a Dermatologist

January 4, 2021

There has been a lot of skincare advice thrown around the internet- but not all of it is good. In fact, some of these “advice” may be harmful to your skin. It’s time to clear the air and put these skincare myths to rest, so that you can start making informed decisions when it comes to your skin.

In this article, we will reveal the truth behind common skincare myths, share dermatologist recommendations on skincare products, and include excerpts from Skincare Bible: Dermatologist’s Tips for Cosmeceutical Skincare by Dr. Teo Wan Lin, dermatologist at TWL Specialist Skin & Laser Centre.

Skincare Myth #1: Skin problems like pigmentation, acne and sensitive skin can be treated with skincare products and facials

Almost every brand is boasting a special cleanser or cream that can treat these problems over the counter, be it in the form of lightening cleansers or anti-acne cleansers or anti-redness creams. The truth is, healthy skin can be maintained with cosmeceutical skincare recommended by dermatologists, but when you have any one of these issues, they are actually true medical conditions of the skin.

My advice is, if you have any of these symptoms, stop self-medicating and applying a bunch of anti-redness or “sensitive skin” products. See a dermatologist as soon as you can because all of the above can be promptly treated with proper medications. This will probably save you a lot of pain, money and regret in the medium to long term.

I have seen so many patients who have spent thousands of dollars on online supplements, fad diets, facials at spas or aesthetic centres, did not get better and actually had a true dermatological condition, such as perioral dermatitis (which looks like acne, for example, but occurs in adults) and rosacea which can be effectively treated by a dermatologist with the correct medications.


Skincare Myth #2: Scrub and use a clay mask.

Dermatologists do not agree with a lot of what beauty companies/aesthetics providers are telling the public. Dermatologists have seen way too many complications because of an incomplete understanding of the actual science of how skin behaves. Scrubbing with harsh beady grains of sand would work if your skin was made of wood, if you imagine using it like a sandpaper. In reality, you do not brighten or “exfoliate’’ your skin with that; rather, you are causing damage and irritation to your skin, that’s maybe even the cause of your sensitive skin and red face problems.

Clay masks are also totally unnecessary, even for oily and acne-prone skin types because it’s actually the salicylic acid content in these masks that causes your acne to get better, but not without really dehydrating your skin after that and causing facial eczema in the long term. Yes it is possible to have oily acne prone skin and facial eczema at the same time.

Dermatologists do not prescribe clay masks for any skin problem because there are much more effective options for treatment of oily skin and acne. What counts in a skin treatment product is the active ingredient in these masks and products, so again, so, do thorough brand research, check the ingredient list of your next bottle or just go with what your dermatologist would recommend.

Skincare myth: clay masks. Use a polysaccharide mask instead.

The MoistureMax Skin Healing Polysaccharide Facial Mask has a unique porous structure that traps cosmeceutical active ingredients in mini-reservoirs within the mask, with enhanced delayed release of cosmeceuticals with minimal transepidermal water loss.

The Silkpeel Home Medi-facial Kit is a home chemical peel equivalent. The effects of the SilkPeel Home Facial Peel System are that of microdermabrasion which has a similar effect to microscopic skin exfoliation.

“Glass skin, a poreless appearance of the skin, popularised by K-beauty isn’t a myth. Cosmeceuticals such as polyglutamic acid, which is a large molecule, sits on the surface of the skin while functioning as a humectant 5x more effective than hyaluronic acid. The SilkPeel system utiliizes polyglutamic acid based solutions with potent antioxidants delivered via vacuum microdermabrasion that helps to achieve a translucent appearance of the skin, reducing the appearance of pores,” accredited dermatologist, Dr. Teo Wan Lin.

Skincare Myth #3: Lower SPF coverage is fine, since SPF represents the duration of sun protection, not the quality.

I read this in a beauty magazine about an aesthetic doctor’s sunscreen product  and honestly this is the sort of stuff that would make a dermatologist cringe, because it is dangerous to spread this sort of belief and sun protection isn’t just about beauty but also skin cancers. It is very enticing  given our humid climate when such brands promise that their sun protection mist offers lightweight cover without leaving a white stain.

Skin cancer can be avoided with good sun protection. In fact, you should never go without a good sunscreen because the harmful sun rays is also the number one cause of ageing. However, beware of the dangers of misleading labels on sunscreens. You should go for a sunscreen recommended by your dermatologist that is at least SPF 30.

A sunscreen should effectively block both UVB and UVA rays, which is possible with an agent that has an SPF of 30 or greater. It is also important that your sunscreen is labeled with the term “broad spectrum”, which means it protects your skin against UVA rays. There are differences between 15, 30, and 50.  SPF is measured in the laboratories whereby the amounts applied at 2g/cm2 and this never happens in real life.

And on top of that, most of us don’t apply sunscreen properly. SPF (sun protection factor) is derived by taking the time it takes you to burn with sunscreen on and dividing it by the time taken for you to burn without sunscreen on. SPF specifically protects against ultraviolet B (UVB) rays that cause sunburn. I would recommend a minimum of SPF 30 for an everyday sunscreen and SPF 50 when outdoors for extended periods of time.

The SunProtector is SPF 50/PA+++ and is exquisitely formulated for humid climates. It is a broad-spectrum sunscreen that also regenerates and soothes sensitive skin. Designed with unique pigments blended to be almost invisible under make-up.
