There are several different types of chemical peels, each indicated for different types and degrees of skin problems. Light (glycolic acid, salicylic acid, lactic acid in lower concentrations) chemical peels, sometimes referred to as “superficial” can improve rough, dry skin, as well as uneven pigmentation. They can also improve the texture of sun-damaged skin and help control acne. A light chemical peel is the mildest type of peel and penetrates the epidermis the least, multiple treatments may be necessary to achieve the desired results. Medium (glycolic acid, salicylic, lactic, TCA in higher concentrations) are best for people who want to smooth out fine wrinkles, remove superficial blemishes, and even out skin pigmentation. Medium skin peels can be used on any part of the body, and the peel depth can be adjusted to best suit the needs of the individual patient. Deep (Phenol) peels can remove major blotching, such as that caused by aging, sun exposure, or birth control pills. Deep peels can also be used to smooth deeper wrinkles. Deep skin peels are only performed by a licensed physician. Deep peels are much more risky and can cause permanent scarring if not used correctly. Acne peels help to control acne and smooth acne scars. A mild, medium, or deep chemical peel may be used, depending on the patient’s skin condition. As with cosmetic chemical skin peels, an acne chemical peel can also reduce or eliminate wrinkles and improve skin pigmentation. Most acne related peels consist of the active ingredient “salicylic acid”, a well known effective treatment for acne patients.
