Glycolic acid acne skin care solution

http://www.advancesinhealth.com/acne-treatment/acne-pimples/acne-problems/index.html Salicylic and glycolic acids are used to exfoliate. Soaps, tinctures, cotton pads and creams are all sold as treatments. Retin-A, a type of vitamin A, also works this way. It is topically applied under a doctor's supervision or taken orally.
