Chemical peels renew the skin by increasing skin tone, reducing fine lines, wrinkles, and smoothing overall skin texture by fading areas of dark discoloration. Additionally, these peels are often used to clear acne prone skin! Superficial chemical peels typically employ glycolic or salicylic acid in varying concentrations. These may be used in a series to achieve the best results and may also be applied to the neck and used to spot treat problem areas, like chicken pox scars.
