A chemical peel is a cosmetic procedure that uses a chemical solution to improve the appearance of the skin on the face, neck, hands, and chest. During the procedure, a chemical solution is applied to the skin, which causes trauma or injury to the skins layers. The skin layers eventually peel off, revealing more youthful skin that is usually smoother with fewer lines and wrinkles, has a more even color, and is brighter in complexion. Chemical peels can be used to treat certain skin conditions or to improve the tone and texture of the skin. They are used to treat wrinkles, discolored skin, scars, and acne. Chemical peels can be done at different depths, from light to deep, and deeper chemical peels offer more-dramatic results but also take longer to recover from. There are three basic types of chemical peels: light, medium, and deep. Chemical peels can cause various side effects, including redness, irritation, and sensitivity to the sun. It is important to consult with a dermatologist to determine the best treatment plan for you.
