On the effect of glycolic acid on acne scars
Among skin diseases, acne scars are often suffered by patients. Recently, the use of glycolic acid in skin care has attracted more and more attention, especially its effect on acne scars.

Glycolic acid belongs to the class of fruit acids, with tiny molecules that can quickly penetrate the surface of the skin. Its primary function is to promote the shedding and renewal of stratum corneum cells. The cause of acne scars is mostly due to abnormal accumulation of the stratum corneum and skin metabolism disorders. Glycolic acid can gently exfoliate old keratin, make the skin surface smooth again, and slow down the bumps of shallow acne scars.

Furthermore, glycolic acid can stimulate the production of collagen in the dermis. Collagen is the support structure of the skin, and its content is related to the elasticity and firmness of the skin. When acne occurs, the dermis is damaged, collagen is lost, and scars are formed. Glycolic acid can stimulate the activity of fibroblasts, making them synthesize more collagen, making the skin firm and scars lighter.

When using glycolic acid, you should also pay attention. It is irritating to a certain extent. For those with sensitive skin, there may be discomfort at the beginning of use, such as redness and tingling. Therefore, it is advisable to try it on a small scale before use to see if the skin tolerates it or not. And the frequency and concentration of use should be gradual, from low to high, to ensure skin safety.

In conclusion, glycolic acid has great potential for the improvement of acne scars. Rational use can help patients reduce scar distress and restore smooth skin. However, individual skin conditions vary, and its effect varies, so it should be used with caution.
