An Analysis of Glycolic Acid and Perioral Dermatitis
In recent years, the way of skin care has attracted much attention. Glycolic acid is quite common in skin care products. However, the public also doubts whether glycolic acid can cause perioral dermatitis?

Glycolic acid is an alpha-hydroxy acid, which is often found in many skin care products and has the ability to exfoliate and promote skin metabolism. It can exfoliate the old waste exfoliation on the surface of the skin, making the skin smoother and more delicate, and the color must be brightened.

However, the tolerance of various parts of the skin is different. The skin around the mouth is relatively delicate and the stratum corneum is thin. If the concentration of glycolic acid in skin care products is too high, or the individual does not take proper care of the skin around the mouth, glycolic acid may irritate the skin around the mouth. When the skin is irritated by this, or triggers an inflammatory reaction, it gradually causes perioral dermatitis. Symptoms may be erythema, papules, with itching and burning.

However, it cannot be generalized that glycolic acid will cause perioral dermatitis. Many factors are related to whether it causes this disease. If the skin care products are well formulated, the concentration of glycolic acid is appropriate, and the user uses them moderately according to their own skin conditions, it may not cause perioral dermatitis. And individual skin characteristics vary greatly, and those with sensitive skin are more tolerant of skin, and are more susceptible to perioral dermatitis due to glycolic acid

To prevent peri-oral dermatitis caused by glycolic acid, users should read the product ingredients carefully and choose the one with the right concentration of glycolic acid. For the first time, skin care products containing glycolic acid can be tried before small pieces of skin to see if they are uncomfortable. Daily skin care should also pay attention to peri-oral skin care to keep it hydrated and increase skin tolerance.

To sum up, glycolic acid may be one of the causes of peri-oral dermatitis, but it is not absolute. Users need to understand their own skin characteristics, choose skin care products carefully and use them reasonably, in order to enjoy the benefits of skin care and avoid peri-oral dermatitis.
