Get the Facts About Common Cosmetic Procedures: Chemical Peels

In this article:

What is it? The American Society of Plastic Surgeons (ASPS) calls chemical peels "one of the least invasive ways to improve your skin's appearance." It involves using an acid-based solution to blister and peel the top layer or layers of your skin, revealing smoother skin beneath. Peels are light, medium or deep, depending on the level of damage you're trying to improve.

Why might I get it done? To reduce the appearance of acne scars, age and sun spots, fine lines and wrinkles, freckles, rough skin and scaly patches, scars and sun damage.

Who is it appropriate for? People with sun-damaged or unevenly colored skin.

How is it done? A peel takes between 30 minutes and three hours, depending on the type used. Your face is cleaned, then a chemical solution composed of several acids is brushed on and left for up to 10 minutes with a mild peel, less with a medium peel. Then the solution is neutralized and cleaned.

With a deep chemical peel, you are given a cream or lotion to use for up to eight weeks to thin the top layers of the skin. The solution is left on for up to two hours and covered with petroleum jelly or strips of adhesive tape for two days.
