What is a damaged skin barrier?

Generally refers to the damage of the stratum corneum, usually manifested as: thinning of the stratum corneum, obvious skin capillaries (redness), poor ability of the skin to lock in moisture and protect the skin (dry and peeling), and skin tolerance Weakened ability (allergies, tingling, itching), large redness or acne, and recurring skin problems.
What should we do if the skin barrier is damaged?
First of all, you need to know what the common repair ingredients are, and choose the correct ingredients according to your own skin problems.

Common repair ingredients:

1. Hyaluronic acid - moisturizing
It can carry more than 500 times its own water molecules, and is currently the best moisturizing substance in nature. It is given the title of ideal natural moisturizing molecule, which can quickly replenish the water lost by sebum.
2. Collagen - water lock repair
It can improve the elasticity and toughness of the mesh fibers of the dermis, lock in moisture, and make the skin less prone to water loss. It can also repair skin damage and maintain skin stability.
3. Amino Acids - Repair Damage
The molecules are small and easy to absorb. After entering the skin, it can repair damaged keratin, hydrate and nourish, improve elastic network breakage, and improve skin immunity.
4. Ceramide - moisturizing and repairing
The main component that constitutes the intercellular matrix can maintain the balance of water and oil, reduce redness and water loss of the stratum corneum, and can also strengthen the skin barrier and remodel cells.
5. EGF epidermal growth factor - repair damage
It can promote cell growth, proliferation and synthesis, and stimulate cell turnover. EGF active small molecules can penetrate deep into the bottom of the muscle, reach the surface of the dermis, repair damaged cells, and also have a good repair effect on acne-prone skin and sensitive skin.
6. Squalane - promotes penetration and locks water
A lipid closest to human sebum, with high affinity, it can accelerate the penetration of other active ingredients into the skin, thereby repairing sebum in time and forming a natural barrier on the skin surface.
