The Application of Glycolic Acid in the Cosmetics Industry

In the salon, the beautician first cleans and rinses the skin area to be treated, and then applies the glycolic acid solution or gel with fingertips or cotton tips or brushes. When treating the face, leave the solution / gel in place for 5-10 minutes, then rinse off with gauze dipped in cold water. Occasionally, use the solution / gel a second time and leave it in place for 5-10 minutes before rinsing. Hand, foot and other body parts are treated similarly.

According to industry sources, products applied to body parts other than the face are usually washed off after about 15 minutes. The end of the treatment is to apply moisturizing cream, which usually contains a sun protection factor (SPF) of 15. A typical course of treatment includes 6-10 peels over 4-6 weeks.

When using at home, lotions, gels, lotions and creams are applied once or twice daily with fingertips or small cotton balls. Scrubs, that is, lotions or creams containing polished particles, rub the skin with a cloth or sponge, and then rinse off with water.

Hair care products such as shampoo and conditioner will apply foam to the hair for a few minutes and then rinse off with water. Intensive hair care products are usually applied to the hair and stay in. In some cases, the glycolic acid manufacturers  recommends covering the head with a plastic film or towel for 15 minutes, then rinse the product under the shower.
