Skin barrier: “A strong shield” for healthy skin

2025-02-05

Nowadays, we are facing plenty of harmful environmental factors such as bacteria, viruses, or even using unsuitable skincare products, causing skin barrier to become weaker! With broken skin barrier, more and more skin problems appear, such as dry skin, irritation, and uneven skin color. Therefore, by understanding and focusing on building strong skin barriers, your skin will come closer to being healthy and bright overall!



What is a skin barrier?

Your skin barrier is part of the stratum corneum, the outermost layer of your skin, and is composed of tough skin cells held together by lipids. Inside the skin cells, you will find keratin and natural moisturizers. 

The lipid layer consists of three main types: cholesterol, fatty acids, and ceramide (anti-aging ingredients account for about 40-50%). The more "solid" this barrier is, the more "equipped" your skin is with the ability to withstand toxic substances and potential pathogens from the environment that can penetrate and bring negative impacts to your body, and your skin, in particular. 

Besides, skin’s protective barrier also helps retain the necessary amount of water for the skin, avoiding escape and evaporation. Thanks to that, your skin will be healthy, moisturized, and have good elasticity!


Signs and causes of skin damage

When the skin barrier is damaged, you will notice it through signs such as: 

  • Skin inflammation: At this time, the skin will lose the ability to prevent harmful components from the environment, such as bacteria, viruses, and pollutants. It results in showing more skin problems: redness, swelling, and burning. Dermatitis can cause your skin to become more sensitive and more susceptible to damage. 
  • Irritation: You will easily notice it, especially after using skincare products that contain strong, active ingredients such as retinoids, acids, or strong exfoliating cleansers. Those ingredients can penetrate deep into the skin layer with broken skin barrier, causing redness and tingling. 
  • Dry, flaky skin: This happens when the lipid layer in the skin gradually disappears, causing the skin to no longer be able to maintain moisture as well as before. Plus, the skin gradually becomes rough and peels off into small scales. Gradually, this dry skin condition leads to more signs of aging appearing, such as sagging skin, wrinkles around the eyes and mouth, and crow's feet. 
  • Dullness: Your skin starts losing its radiance and brightness with a compromised skin barrier. In addition, a damaged skin barrier also leads to an imbalance in the production of melanin (skin's natural pigment). Along with dullness, you could also see brown spots and uneven color, which often appear when you get old, however, with a broken skin barrier, this process becomes faster!


How to repair damaged skin barrier?

  • Minimize your skincare routine: One of the reasons that weakens the skin barrier starts from trying to apply too many product layers in a complicated way. Consider only using skincare products that are suitable for you, avoid using too many special treatment products, and "listen" to how your skin reacts to that product! 
  • Pay attention to pH: pH is an index measuring the acidity or alkalinity of a substance on a scale from 0 to 14. As pH shows part of your skin's health at that time, choosing suitable products with an ideal pH (4.5 to 6.5) is important in strengthening healthy skin. 
  • Invest in more products with “skin-loving” ingredients: Famous ingredients include Hyaluronic Acid (HA), Niacinamide, Ceramides, Peptides... Each ingredient has a special effect to protect the skin, and helps the skin's "wall" become stronger, from protecting moisture, increasing elasticity, and reducing wrinkles to stimulating collagen production. All help create smoother and more youthful skin!
