Chemical Peel involves applying a thin layer of chemical agent on the skin to remove the dry dead layer on the surface, therefore creating a smoother and fresher-looking skin. The deeper the peel, the more extensive the skin is renewed. Medium and deep peels stimulate collagen renewal, resulting in firmer and tighter skin.
Alpha hydroxy acid (AHA) is the commonest kind of chemical peeling agent used. This is a group of acids commonly known as fruit acids and includes glycolic acid, lactic acid and citric acid. Glycolic acid is the commonest used and this provides a superficial peel. Other chemical agents include TCA and Jessner's solution. These penetrate deeper than glycolic acid giving medium to deep peels.
