Salicylic and Glycolic Acid
Glycolic acid is contained in some cosmetics that are labeled “non-comedogenic,” meaning that they do not clog your pores. Salicylic acid, on the other hand, is used in acne-fighting products. Salicylic acid is a type of acne-fighting ingredient found in a number of over-the-counter products such as cleansers, toners and even moisturizers. According to the Mayo Clinic, alpha hydroxy acids are synthetic acids made from sugary fruits. A common alpha hydroxyl acid is glycolic acid, and is contained in acne products as well as cosmetics and chemical peels. The Mayo Clinic explains that salicylic acid works by reducing the amount of dead skin cells that trap inside the pores. This prevents the formation of acne pimples and helps remove blackheads and whiteheads.
