A chemical peel is a skin-resurfacing procedure in which a chemical solution is applied to the skin to remove the top layers. The skin that grows back after a chemical peel is smoother and younger looking. Chemical peels are used to treat wrinkles, skin discoloration and scars — typically on the face. A chemical peel can be done alone or in combination with other cosmetic procedures. Chemical peels can be done at different depths — light, medium or deep — depending on your desired results. Each type of chemical peel uses a different chemical solution. Deeper chemical peels produce more-dramatic results, but also involve longer recovery times.
