What is alpha hydroxy acid?
Alpha hydroxy acid is an acid derived from fruits. Various alpha hydroxy acids have been in use for centuries to help reduce wrinkles and exfoliate the skin of the face. In higher concentrations, alpha hydroxy acid is used in chemical peels. Alpha hydroxy acid products sold over the counter must have a concentration of 10% or less. Licensed dermatologists and cosmetologists can purchase products with a 20% to 30% concentration of alpha hydroxy acid. Doctors have access to potent concoctions with a concentration of 50% to 70%!
