A chemical peel is a technique used to improve the appearance of the skin on the face, neck or hands, and sometimes the back. The solution is applied to the skin for a certain time, and that causes it to exfoliate. The new, regenerated skin is usually smoother than the old skin.
Chemical peels can be classified into 3 different types:
Superficial or lunchtime peel: Mild acid is used to penetrate only the outer layer of skin to gently exfoliate it. The treatment is used to refresh the skin.
Medium peel: examples include Glycolic or trichloroacetic acid (TCA) is applied to penetrate the out and middle layers of skin to remove damaged skin cells. The treatment is used to improve age spots, fine lines and wrinkles, freckles and moderate skin discoloration.
Deep peel: examples include Tricholoracetic acid (TCA), Jessner or phenol is applied to deeply penetrate the middle layer of skin to remove damaged skin cells. Patients will see a dramatic improvement in skin appearance. This treatment has the longest downtime.
