On the cause of acne caused by glycolic acid
The use of glycolic acid in skin care is quite extensive, but the suspicion of acne is often discussed by everyone.

Glycolic acid, which belongs to fruit acids, has the ability to exfoliate, can make the skin surface old exfoliation, make the skin renewed, and promote the metabolism of the skin, help skin care products absorption, which is also beneficial.

However, it may cause acne, but it is not without reason. First, excessive exfoliation. If the concentration of glycolic acid is too high and the frequency is too high, the stratum corneum of the skin will be excessively exfoliated, resulting in damage to the skin barrier. The skin loses its strong barrier and is easily invaded by external stimuli. In order to protect the skin, the sebaceous glands secrete more oil. The oil mixes with exfoliated keratin, blocking the pores, resulting in acne. Second, individual skin adaptability is different. People have different skin characteristics. Those with sensitive skin have low tolerance to glycolic acid. Even if used at normal concentrations, it may also trigger an inflammatory reaction in the skin, stimulate abnormal keratinization of the epithelial cells of the hair follicle sebaceous gland ducts, and then induce acne. Third, product impurities or irritation. Some glycolic acid products, if the production process is not good, contain impurities or irritating ingredients, which cooperate with glycolic acid to stimulate the skin, affect the stability of the hair follicle sebaceous gland microenvironment

If you want to avoid acne caused by glycolic acid, you should carefully choose the product according to your own skin condition, control the concentration and frequency of use, and try it on a small area of skin first to see if there is any discomfort. In this way, you can get the benefits of glycolic acid skin care and avoid the harm of acne.
