On the Effect of Glycolic Acid on Repairing Skin Barrier
The person who protects the skin barrier is like the guardian of the city. It is essential for the health of the skin. Since modern times, glycolic acid has attracted more and more attention in the way of skin care, and its ability to repair the skin barrier has been particularly explored by the world.

Glycolic acid is an alpha-hydroxy acid and the like. Its molecules are small and can travel unimpeded and penetrate deep into the bottom layer of the skin. Because of its hydrophilicity, it can attract water molecules from the skin, so that the skin is hydrated and full, which is the basis for repairing the skin barrier.

The damaged state of the skin barrier of the spectator often shows signs of dryness and weakness. The effect of glycolic acid is first to promote keratin metabolism. In the stratum corneum, if masonry is accumulated, it may cause disorder over time. Glycolic acid can peel off keratinocytes in an orderly manner, returning them to a regular arrangement, and restoring the density of the barrier.

And glycolic acid can stimulate the synthesis of collagen. Collagen, like the backbone of the skin, gives the skin elasticity and toughness. When the skin is disturbed by the outside world, collagen is gradually damaged, and the barrier is also not firm. Glycolic acid can activate the ability of cells, promote collagen regeneration, make the skin firm, and strengthen the barrier.

And it can regulate the acid-base balance of the skin. The skin has its own acid-base level, and imbalance is easy to attract external evil. Glycolic acid, with its characteristics, regulates the acid and alkali of the skin, creates a comfortable environment, and helps the barrier repair power.

When using glycolic acid, it is also necessary to be cautious. Because of its certain irritation, it should be paid special attention to those with sensitive skin. For the initial trial, low concentration and frequency should be used, and the amount should be adjusted gradually after observing the skin's response. And for daytime use, strict sun protection is required to avoid the risk of light sensitivity.

In short, glycolic acid has great potential for the repair of the skin barrier. When used properly and applied according to the nature of the skin, it can build a strong barrier for the skin and restore the brilliance of the skin.
