Heal Your Skin Barrier

Medically reviewed by Dr. Teo Wan Lin, board certified dermatologist, Author of Skincare Bible  

Skin barrier products are more than moisturisers. The ideal skincare product repairs the barrier from inside out and also builds skin resilience. But it turns out that it’s not just a single product that will work. According to board-certified dermatologist Dr Teo Wan Lin, author of Skincare Bible: Dermatologist’s Tips on Cosmeceutical Skincare, “the ideal skincare routine must address all functions of the skin—and a healthy skin barrier is but the most important.”

What is the skin barrier?

The skin barrier refers to the protective function of skin—namely comprising the epidermis and the dermis. This forms a barrier between your internal organs and the external environment. Typically, a breach in the skin barrier can be caused by a cut, injury or because of underlying inflammation. This can trigger off allergic reactions, as external allergens like dust, pollen can present itself to the immune cells. It can also lead to infections due to bacteria coming into contact with areas of broken skin.

Skin barrier damage symptoms

We begin with understanding the symptoms of a damaged skin barrier. 

  • Redness
  • Itch
  • Stinging
  • Flaking
  • Skin tightness
  • Swelling 
  • Irregular skin texture 

These are the commonest symptoms. However, dermatologists usually screen for a personal or family history of

  • Eczema
  • Allergies
  • Allergic rhinitis
  • Asthma 

These are known as the atopic triad, which increases one’s risk of developing itchy sensitive skin problems known as dermatitis 

Skin barrier damage causes

Eczema or dermatitis are common conditions related to skin barrier damage. However, there are subsets of dermatitis i.e. contact dermatitis which is due to direct allergy or irritation from caustic substances. Nickel allergy is a type of allergic contact dermatitis. Frequent hand washing leading to hand dermatitis is a type of irritant contact dermatitis. On the face, facial eczema can occur due to use of harsh cleansers or it could be due to underlying atopy. Atopic dermatitis can also be triggered off by changes in the weather, due to increased transepidermal water loss.

The process of repairing the skin barrier is as follows:

Layer your moisturisers for maximum effects







The mnemonic SLEMM created by Dr TWL summarises how to approach the sequence of using skin barrier repair products. 

The key principles are: 

  • Use the most lightweight textures first, followed by the heavier creams
  • All products are applied on damp skin this increases absorption of skincare
  • The layering process re-creates a moist environment which is ideal for wound healing
  • The key is consistency and frequency—facial mists are an example of a skin barrier repair spray type moisturiser that can heal the skin barrier when used frequently

How can I strengthen my skin?

The skin barrier has been described as a brick wall model—bricks joined by cement which dermatologists refer to as a ceramide, a fatty lipid produced by the body. If you have eczema, you likely have a genetic defect in a gene known as fillagrin. Fillagrin deficiency causes severe cases of atopic dermatitis and also icthyosis vulgaris, where fish-scale like lesions appear on areas such as the shin. This is generally an inherited condition. 

Strengthening the skin barrier can be understood as a sandwich model. The layers you apply essentially create the ideal skin healing environment.

The main principles are: 

  1. Use a layering technique as above
  2. Enhance absorption skincare products by using technology
  3. Preventing escape of moisture to the environment (known as Transepidermal Water Loss)

What product is good for the skin barrier? 

When choosing a product to incorporate into your skin barrier repair regimen, you should consider the following:

1. What is the texture of the product?

If you live in a humid country such as Singapore, you may find that cream moisturisers are uncomfortable to use in the daytime. If you have oily skin you may find it more appealing to use lightweight serums and lotions instead. You can use a moisturising cream at night. The type of moisturiser formulation makes a difference to skin barrier repair efficiency—ceramide based non-occlusive, non-comedogenic formulations are important for those with combination/oily skin types. 

2. How easily can I incorporate this into my daily skincare routine? 

Most people find it impractical to reapply moisturiser throughout the day. The facial mist is one product that helps deliver moisture consistently—easily apply over, under makeup, even use it for refreshing your skin and touch-ups in the day time. 

3. How often can I apply it? Is it convenient to use? 

Consistency is key when it comes to skin barrier repair products. Consider using a skincare routine planner if you are new to building a skincare regimen.

1. Skin barrier cream

The Multi-CERAM Moisturiser Cream is formulated for universal skin types based on an ideal lipid ratio with additional anti-inflammatory benefits. It is dermatologist recommended for adjunct treatment of eczema and other forms of dermatitis. It is also non-greasy and helps to heal the skin barrier from the inside out. A combination of active ceramides and botanicals creates the optimal skin microenvironment.

2. Skin barrier spray 

Spray on products are especially helpful. Since moisture is lost to the environment constantly, the more often moisturisers can be reapplied, the more effective the skin barrier repair therapy will be. The best skin barrier repair spray takes the form of a facial mist — one that contains traditional moisturising ingredients such as glycerin, hyaluronic acid and polyglutamic acid. Don’t just use thermal water sprays—minerals are beneficial for skin but active ingredients need to help skin attract moisture from the environment. This is where humectants are beneficial. Newer facial mists contain multifunctional actives that can also help to boost skin resilience. This means that it can also improve the skin’s ability to fight off free radical damage—known as oxidative stress caused by environmental pollution. 

3. Skin barrier repair serum 

Hyaluronic acid is a star when it comes to skincare products, but most don’t realise that concentration is the most important. Maximum concentrations of 1% are used in our in-house formula, which ensures deep hydration. Hyaluronic acid doesn’t just attract moisture— we utilise a multi-weighted formulation that targets all levels of skin. The epidermis, dermis and also the cells involved in immune function. Hyaluronic acid participates in a process known as cell talk which encourages holistic healthy functioning of skin.

4. Which moisturiser is best for skin barrier?

Ceramide based moisturisers directly replace the deficient lipids, but dermatologists are more concerned with how often moisturisers are applied and the technique of application. 

Here are the best practices according to Dr. TWL:

  • Choose a holistic moisturiser that contains ceramides, hyaluronic acid and anti-inflammatory botanicals that can reduce long term reliance on steroid creams 
  • Always apply on damp skin and keep your skin damp as long as possible to let the moisturiser deeply penetrate skin 
  • Using a wet cotton towel or using a polysaccharide material can significantly enhance
  • Check the effectiveness of your skin barrier repair routine with a skin hydration analyzer.

5. Skin barrier repair mask  

There are 3 main types of face masks

  • Wash off
  • Leave on sleeping masks 
  • Dry masks 

Wash off gel masks can contain slightly irritating acidic ingredients like vitamin C which can help to brighten skin and strengthen skin immunity. Leave on masks tend to be overnight masks which are really just moisturisers marketed as sleeping masks. Use a palm-sized amount and leave on overnight. Dry masks are quite novel, they essentially recreate the optimal skin microenvironment under occlusion. Silicone or other polymers for instance like hydrocolloid can be very efficient skin barrier repair masks. These are usually applied overnight or for at least 3 hours at a stretch. It can significantly improve the barrier function of the skin. 

6. Skin barrier loving face cleanser

Le Lait Milk Cleanser Moisturising Face Wash

Face cleansers are the second most important skin barrier repair product. Cleansing is essential in order to maintain a healthy skin microbiome. However, many commercial cleansers are based on harsh surfactants. Alternative emulsifiers such as amino acid surfactants or botanicals like soy or honey-based products are gentler on the skin barrier. Our pharmacy’s top pick is a cream cleanser which really is an emulsion—this is an oil in water formula that helps dissolve oil dirt and grime. It also contains multiple skin hydrating ingredients so you cleanse and moisturise your skin in just 1 step

7. Skin barrier loving makeup removal pad

Makeup wipes are terrible for the skin barrier—that’s one thing you should ditch. Instead, invest in a gentle microfibre reusable makeup pad that can work to remove makeup without the use of surfactants. Our micellar makeup pad utilises hydrophobic/hydrophilic interactions to remove tough makeup pigments with just the hydrating cleanser alone.
