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. After the one week period, use the product every other night for one week to the face, chest, back of the hands and other sun damaged areas. It is OK to use the alpha hydroxyacid in the morning if you prefer.
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 treat microscopic lesions. When you put alpha hydroxyacid on your skin, it will burn for a few minutes. This is normal.
