A Chemical peels is a procedure in which a chemical solution is applied to the skin to remove the top layers. The skin that grows back is smoother. With a light or medium peel, you may need to undergo the procedure more than once to get the desired results. Chemical peels are used to treat wrinkles, discolored skin and scars — usually on the face. They can be done alone or combined with other cosmetic procedures. And they can be done at different depths, from light to deep. Deeper chemical peels offer more-dramatic results but also take longer to recover from.
