Chemical peels can improve the skin's appearance. In this treatment, a chemical solution is applied to the skin, which makes it "blister" and eventually peel off. The new skin is usually smoother and less wrinkled than the old skin.

Chemical peels can be done on the face, neck, or hands. They can be used to:

• Reduce fine lines under the eyes and around the mouth
• Treat wrinkles caused by sun damage and aging
• Improve the appearance of mild scars
• Treat certain types of acne
• Reduce age spots, freckles, and dark patches (melasma) due to pregnancy or taking birth control pills
• Improve the look and feel of skin

Areas of sun damage may improve after chemical peeling.

After a chemical peel, skin is temporarily more sensitive to the sun, so wear sunscreen every day. It should say "broad-spectrum" on the label, meaning it protects against the sun's UVA and UVB rays. Also, it should be a physical sunscreen and be above SPF 30. Limit your time in the sun, especially between the hours of 10 a.m. and 2 p.m., and wear a wide-brimmed hat.

Generally, fair-skinned and light-haired patients are better candidates for chemical peels. If you have darker skin, you may also have good results, depending upon the type of problem being treated. But you also may be more likely to have an uneven skin tone after the procedure.

Skin sags, bulges, and more severe wrinkles do not respond well to chemical peels. They may need other kinds of cosmetic surgical procedures, such as laser resurfacing, a facelift, brow lift, eyelid lift, or soft tissue filler (collagen or fat). A dermatologic surgeon can help determine the most appropriate type of treatment for you.

Tell your doctor if you have any history of scarring, cold sores that keep coming back, or facial X-rays.

Before you get a chemical peel, your doctor may ask you to stop taking certain drugs and prepare your skin by using other medications, such as Retin-A, Renova, or glycolic acid. The doctor may also prescribe antibiotics or antiviral drugs.

Work with your doctor to determine the depth of your peel. This decision depends upon the condition of your skin and your goals for treatment.

Ask the doctor in advance whether you will need to have someone drive you home after your peel.
