"On the Effect of Glycolic Acid on Periwiry Keratosis"

Periwiry keratosis, commonly known as "chicken skin", has fine papules on the skin, reddish or normal in color, mostly on the outside of the upper arm, the side of the thigh and other parts. Although there is no major problem, it affects the appearance.

Glycolic acid is an important member of the fruit acid family. Its small molecule and good permeability have attracted much attention in the field of skin care.

For periwiry keratosis, glycolic acid has a significant effect. First, it has excellent exfoliation power. It can loosen the connections between keratinocytes, causing the accumulated stratum corneum to gradually fall off, making the skin surface smooth. The abnormal keratin accumulation in the peri-hairy keratosis area can be gradually improved by the action of glycolic acid, and the roughness of the papules can be relieved. Second, glycolic acid can stimulate the synthesis of collagen in the dermis. Long-term moderate use of products containing glycolic acid can enhance skin elasticity, improve local skin texture, and make the skin more delicate. Third, glycolic acid can also adjust the acid-base balance of the skin, optimize the skin microenvironment, create good conditions for the normal metabolism of the skin, and is conducive to the relief of peri-hairy keratosis.

However, when using glycolic acid, you should also be cautious. Because of its certain irritation, it is advisable to start with low-concentration products at the beginning of use and gradually build up skin tolerance. During use, if the skin experiences redness, swelling, tingling and other discomfort, it should be stopped immediately and a professional should be consulted.

In short, glycolic acid has great potential in improving pericarp. Reasonable and moderate use is expected to help patients regain smooth skin.
