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.
