Chemical peels work by "ungluing" the top layer of damaged and discolored skin so it can peel away and reveal the fresh new skin beneath. By forcing the turnover of the cells, the old dull and damaged cells peel off much more quickly.

Lighter superficial peels using Alpha Hydroxy acids such as Glycolic Acid can be very effective in a series of "no downtime" procedures. Your skin will have a light pink look and flaking or peeling may be unnoticeable. Superficial peels are ideal for improving pigmentation problems, fine wrinkles and sun damage. They can be used anywhere on the face and body.
