How to repair a damaged skin barrier

Our skin is such a complicated yet sophisticated organ. It is made of many layers to keep our bodies protected from external environmental stressors or microorganism. To keep our skin’s health and to function normally, our skin is armed with a barrier layer or also commonly known as the “skin barrier”. Read the whole article if you want to learn more about what the skin barrier is, how to keep it healthy, how to prevent a damaged skin barrier, and what to do when it unintentionally damaged.

What is the skin barrier?



Our skin barrier is part of the top layer of our skin called the stratum corneum. It is made up of corneocytes (skin cells) and lipid interface that glued them together. To make it easier, it is also called as the “brick-mortar” structure. Corneocytes as the brick and lipid interface as the mortar. The lipid interface is made up of free fatty acids, cholesterol and ceramides. On their best state, this skin barrier will shed off their top layer which causes our skin natural exfoliation, keep our skin’s moisture intact and protect allergens from getting inside and causing irritation.

Causes of Skin Barrier Damage

Our skin barrier can be disrupted due to many possible reasons. When it’s damaged the tight arrangement between the skin cells are lost. This allows external irritants to get in our skin a lot easier and lead to more water leaving our skin. Damaged skin barrier is characterized by an easily irritated, dehydrated and flaky skin. Your skin is red, irritated, tight yet very oily.


Does this sound familiar to you? When these happen out of the blue, most probably your skin barrier has been damaged. Now before we learned on how to deal with it, it is better to track down their root causes since some of it might be caused by our own skincare mistakes that we can prevent in the future. Here are some of the most common causes of a damaged skin barrier:

Common external causes of damaged skin barrier can vary from our basic routine up to environmental factors, such as:

1. Overwashing

An overexposure to water and harsh cleanser could be the cause of a damaged skin barrier. It can strip away the natural lipid barrier on our skin. Instead of protecting your skin from dirt and impurities, it could damage the skin's first protective layer which provides most of the protection.

2. Over-exfoliating

With more varieties of exfoliating products on the market and tendency for an instant gratification in your skincare routine, over-exfoliating is more of a common thing recently. When you over-exfoliate your skin, you’re not only taking away the unwanted dead skin cells on the top layer of your skin but also the functional “skin barrier” that are present to protect you in the first place. Always be mindful while you’re using your exfoliating products and observe any differences on your skin, this allows you to STOP doing it when needed.

3. Pollution, bad or dry air quality

Research has shown that pollution and dry air can affect our skin barrier layer. Thus, it is very common for people to experience sensitive and itchy skin when the air quality is poor. Therefore, it is best to limit outdoor activities during pollution, wear protective mask and clothing outdoors or use an air purifier in your living space to keep the air clean. This won’t only benefit your skin but also your general health in general.

4. Stress and lack of sleep

Have you ever experienced any “bad skin” day when you have lack of rest and sleep? Yes, because it has been shown through research that lack of sleep or rest can damage your skin barrier and lead to an increased transepidermal water loss. Get more rest, sleep and protect your skin barrier!

Some internal factors that are out of our control in general are:

1. Genetics

While this is much beyond our control, some people have genetically impaired component of the skin barrier. They are either lacking in production of any components which is linked to one another on keeping our skin barrier. We commonly see this on people with atopic dermatitis or eczema. However, we can totally practice a safe and healthy skincare habits to prevent them from getting even worse.

2. Ageing

Unfortunately, as we age, our skin barrier get weaker. This is why it’s not uncommon for people to experience drier and more sensitive skin as they aged.

How to repair damaged skin barrier?



So once it happened, what should you do next? Here we compile some tips on each step and what to do when your skin barrier is damaged.

1. Find the root cause

Yes, it’s not as easy as it sounds, but once you narrow down any possible causes (especially if it’s due to your own skincare habit) it’s a lot easier to tackle and prevent from happening in the future. Check on each of the causes point that we’ve mentioned above. Have you been over washing or over-exfoliating? How’s the air quality or your sleep quality?

2. Limit frequency and time for face washing

While water is necessary to keep our skin function normally and hydrated, it can dry out our skin even more and lead to more damage. Therefore, wash your face just once or at maximum twice a day with lukewarm water, and gentle and low pH cleansers that won’t exacerbate the loss of lipid barrier on your skin.

3. Stop exfoliating for a while

With a compromised skin barrier, stop exfoliating! This will allow your skin to regenerate it’s skin barrier. Once all the symptoms have resolved, you can slowly start incorporating exfoliation back to your routine.

4. Moisturize your skin

The most essential step in your skincare routine, especially during this time point. Putting back just hydration won’t do as much as it will be easily evaporated through the damaged skin moisture barrier. Therefore, it is important to seal them with your moisturizer, while your skin is losing more water than it usually is, all you want to do is to keep water in our skin for as long as possible. Ingredients such as ceramide, niacinamide, panthenol and fatty acids are the best to keep your skin barrier happy and healthy.

5. Don’t test out new skincare products

While your skin is not at its prime, it’s not the best idea to try out new products since your skin is more easily irritated and may react to new product. Ingredients have a greater chance of irritating your skin and exacerbates the inflammation, therefore avoid trying out new products at this period.

6. Keep your skincare routine simple

Yes, always go with the basic. This allow less chance of irritation on your already irritated skin. The basic step to maintain a healthy skin barrier when it is at its’ lowest are: Cleanse, Moisturize, and Protect. These three steps are the essential step while your barrier is recovering. Any additional hydration from a toner and/or serum is a bonus but make sure that you are familiar with the serum that you’re currently using.

  • Hi Zintle. I’ve been on a heck of a journey to repair my skin barrier after using retinol. It led to endless cystic acne breakouts that have been tormenting me and I thank Covid that I don’t have to put on makeup frequently. I’ve been doing so much research trying to sort this out. This is one of the articles I’ve read (that are available) that gets down to it – simplify the routine – cleanse, moisturize, protect. I’ve recently started using products by Innis free – most helpful has been the cica balm for moisturizing. Holy crap! Within 24 hours of using it, cystic acne that was developing started fast forwarding all the way to white heads. For the first time in 2 months I don’t have 4 new cysts a day. I’m still breaking out (it’s that time of the month too) but the cica balm really is working and I know I’m finally moving in the right direction towards clearer skin. I’ve just purchased an emulsifier sunscreen that’s also produced by Innis free to lock in that moisturize for when I have to leave the house without getting the ghost face that comes with using sunscreen made with zinc oxide and it’s also non-comodogenic. My skin isn’t in the clear yet, but it feels the most amazing that it’s felt in YEARS. I highly recommend it. Get away from antibiotics and prescription meds. They’re stripping away the natural defenses that are skin has to produce a result that isn’t even guaranteed to last, let alone work.

  • My face skin is damaged. Because I have acne,I’ve tried to use different products & they are not helpful…
