Chemical peels are acids which are applied to the skin about once every two weeks.1-2 These acids chemically exfoliate the top layers of skin. This exfoliation signals the cells inside the skin to produce more rapidly, which can help hasten skin turnover and prevent pores from becoming clogged. At this time there is no evidence showing whether any one type of peel works better than another. From the data we currently have, they all appear to have similar efficacy. Chemical peels are also sometimes used to help lessen the appearance of acne scars.
Do they work?
Studies show about 45-50% reduction in acne lesions after a series of 4-6 peels. Most study participants report a “fair” to “good” result.Results tend to last for 1-2 months, with acne beginning to reassert itself at this time.
Most people experience a sun burnt look with obvious peeling of the skin in the days after their first peel. This redness and peeling tends to be less pronounced with each consecutive peel.
Because chemical peels peel away the protective layers of the skin, your skin will be much more sensitive to sunlight and UV rays. It is extremely important to keep your skin out of the sun after a peel and to use an adequate SPF.
