On glycolic acid and the improvement of skin roughness
The state of the skin is related to the beauty of the face. Nowadays, glycolic acid has attracted much attention in improving skin roughness.

Glycolic acid is a member of the α-hydroxy acid family. Its molecules are small and can easily penetrate the surface of the skin and reach the depths of the stratum corneum. In the stratum corneum, the outermost barrier of the skin, its cells are closely connected. Sometimes, due to slow metabolism, keratin accumulates, and the skin appears rough.

Glycolic acid has a unique ability to loosen the connections between keratin cells, making old keratin easy to fall off. This process is like a spring breeze blowing away dead branches, making the skin look new. With the removal of old keratin, the surface of the skin becomes smoother, and the original rough texture gradually becomes more delicate.

And glycolic acid can stimulate the rate of skin metabolism. Metabolist, the process of skin cells reclaiming the old and new. When this rate is accelerated, new cells quickly replace old cells, and the vitality of the skin is improved. New cells are rich in moisture and collagen, which can fill the skin and further improve the roughness caused by dryness and sagging.

In addition, glycolic acid may promote the synthesis of collagen. Collagen is also the support structure of the skin. If collagen is sufficient, the skin is firm and elastic. When collagen synthesis increases, the texture of the skin is more uniform, and the roughness will be reduced.

However, the use of glycolic acid to improve skin roughness should also be cautious. Because it is irritating to a certain extent, if used improperly, it may cause skin redness and tingling. Therefore, before using it, conduct a skin test, and choose the appropriate concentration and frequency of use according to your own skin tolerance.

In summary, glycolic acid does have potential to improve skin roughness, but it can be used reasonably to achieve the effect of beautiful skin and achieve a delicate and smooth skin.
