Chemicals peels are cosmetic treatments performed on facial skin. These involve one or more exfoliating agents being applied to the skin to remove the rough upper layer of skin, decrease wrinkles or skin sun damaged, and stimulate the rejuvenation of new skin cells. Chemical peels are used to improve and smooth the texture of the facial skin, neck and hands. Using different levels of chemicals, the treatment causes the dead skin to slough off and eventually peel off. The chemical peels can be light, medium or deep, according to the depth that they penetrate the skin. Light and medium peels are used for superficial wrinkles and skin discolouration, whereas deep peels are used for conditions like severe acne.
