Chemical peeling is a procedure used to treat wrinkles, acne, skin discoloration and other minor skin imperfections. It involves the application of a chemical solution, usually acid-based, to the skin in order to remove the outer layers. This results in the production of new, smoother and more evenly-toned skin. Chemical peeling can be used to treat wrinkles, reduce the appearance of acne scars, smooth out skin texture and lighten dark spots. It is generally considered safe when performed by a qualified professional.
