A superficial chemical peel removes the top layer of dead skin cells. It is performed to give the skin a smoother appearance that is more even in colour. These peels can be used to treat sun-damaged skin and fine wrinkles, increased pigmentation and acne.
Superficial chemical peels can contain trichloroacetic acid, glycolic acid, lactic acid and salicylic acid.
You often need 4-6 peels spaced 4-6 weeks apart. The skin may be slightly red and tingle for up to a few days after treatment.
