The most common alpha hydroxyacids used for treatment of these problems are lactic acid and glycolic acid . Alpha hydroxyacids work very well when combined with Retin-A for the prevention of precancerous skin lesions and also this combination will reverse some of the changes of aging including brown sun spots , fine lines and wrinkles. For the first week, use the product every other day to the face. It is OK to use the alpha hydroxyacid in the morning.
Men can use it as an after shave.
Wait 15 minutes before applying make-up or sunscreen over top of the alpha hydroxyacid. When using alpha hydroxyacid, apply to all of the skin in the area, not just to the spots you want to treat. This will help prevent new lesions. When you put alpha hydroxyacid on your skin, it will burn for a few minutes. This is normal.
