Chemical peeling and enzymatic peels involves applying a chemical solution to the skin to remove its outer layers in order to improve the appearance of the skin.
How much skin they remove and how deep they penetrate will depend on the type of peel used, its strength and how long it is left on.
The lower the pH, the deeper the peel, (except in the enzymatic peeling). Anything with a pH of less than 2.0 should be done by a doctor or nurse. Peels with a pH of 3 are what usually find in a beauty salon.
