What is Skin Barrier?
What is the skin barrier? The answer is simple: it is a system of cells and a matrix.
The topmost layer of the skin is called the Stratum Corneum. This layer is composed of tough skin cells aligned as bricks. The matrix that fills the spaces between these cell bricks is called Mortar and is composed of lipids, cholesterol, fatty acids, ceramides, and proteins. This compact system is selectively permeable and allows only valid substances into the body.
Another essential component of the skin barrier is Natural Moisturising Factors (NMF). These natural moisturisers are called Humectants and act as water magnets, trapping moisture in the skin cells. Some of the Natural Moisturising Factors are,
- Free amino acids
- Urea
- Lactic acid
- Sodium PCA

Common Causes of Skin Barrier Damage
In order to know how to improve the skin barrier, we must understand its causes. There can be several different causes of skin barrier damage. External trauma or any aggressor can disrupt the skin barrier. Some of the causes of skin barrier damage are discussed below:
Extreme Weather
Extreme hot or cold temperatures can disrupt the skin barrier.
Harsh Chemicals
Harsh chemicals in soaps, detergents, and skincare products can damage the skin barrier. Harsh chemicals can even burn the skin. So, you should be very careful when selecting products for the skin.
Sun Exposure
Sun exposure is another common cause of damaged skin barrier. Prolonged exposure to UV rays can not only cause heat rashes, but it can also damage the skin barrier.
Over Exfoliation
Both chemical and physical exfoliation are great ways to get rid of dead skin cells, but over-exfoliation can not only dehydrate the skin, but it can also damage the skin barrier.
Skin Conditions
Underlying skin conditions like eczema, rosacea, and psoriasis can contribute to disruption of the skin barrier.
Ageing
Ageing affects the cellular turnover and production of collagen. This can result in a vulnerable skin barrier, which can be easily damaged.

Best Ingredients for Skin Barrier Repair
To repair skin barrier damage, you need to heal the skin or let it heal by using soothing, moisturizing, calming, and hydrating ingredients. Here are some skin barrier repair skincare ingredients:
Ceramides
Ceramides are Lipids that form part of the natural skin barrier. They perform skin barrier protection by filling spaces between the skin’s brick cells.
Niacinamide (Vitamin B3)
Niacinamide is another wonderful ingredient that helps to strengthen the skin barrier by promoting lipid production in the skin. It also reduces inflammation and redness.
Hyaluronic Acid
Hyaluronic acid is an excellent humectant. Hyaluronic acid provides skin barrier protection by attracting and trapping water molecules in the skin, leaving bouncy, supple, and well-hydrated skin.
Fatty Acids
Fatty acids are naturally present in the skin barrier. Linoleic acid is an example of a fatty acid that promotes skin barrier protection.
Oats Beta Glucan
This ingredient is derived from oats. It is very helpful in reducing inflammation, hydrating the skin, and replenishing the damaged skin barrier.
Panthenol (Vitamin B5)
Panthenol is a calming ingredient. It reduces inflammation and irritation and helps in repairing the damaged skin barrier.
Glycerin
A staple in our mothers and grandmothers’ barrier repair skincare, glycerin is an ingredient that deeply nourishes the skin and hydrates it from within.
Centella Asiatica (cica)
Centella is an ingredient gaining popularity in Korean Skincare. It is known to calm the skin and repair the damaged skin barrier by reducing inflammation.

Too many Products
Adding too many serums, essences, toners, moisturizers, night creams, etc., in your skincare regime can harm your skin barrier.
