How you prepare

Choose a doctor with knowledge of the skin and procedure — a dermatologist or dermatologic surgeon. Results can be variable and depend on the expertise of the person doing the peel. Improperly done, a chemical peel can result in complications, including infection and permanent scars.

Before you have a chemical peel, your doctor will likely:

• Review your medical history. Be prepared to answer questions about current and past medical conditions and any medications you are taking or have taken recently, as well as any cosmetic procedures you've had.
• Do a physical exam. Your doctor will inspect your skin and the area to be treated to determine what type of peel you might benefit from most and how your physical features — for example, the tone and thickness of your skin — might affect your results.
• Discuss your expectations. Talk with your doctor about your motivations, expectations and potential risks. Make sure you understand how many treatments you might need, how long it'll take to heal and what your results might be.

Before your peel, you might also need to:

• Take antiviral medication. Your doctor might prescribe an antiviral medication before and after treatment to help prevent a viral infection.
• Use a retinoid cream. Your doctor might recommend using a retinoid cream, such as tretinoin (Renova, Retin-A) for a few weeks before treatment to help with healing.
• Use a bleaching agent. Your doctor might recommend using a bleaching agent (hydroquinone), a retinoid cream, or both before or after the procedure to reduce the risk of side effects.
• Avoid unprotected sun exposure. Too much sun exposure before the procedure can cause permanent irregular pigmentation in treated areas. Discuss sun protection and acceptable sun exposure with your doctor.
• Avoid certain cosmetic treatments and certain types of hair removal. About a week before the peel, stop using hair removal techniques such as electrolysis or depilatories. Also, avoid hair dying treatments, permanent-wave or hair-straightening treatments, facial masks, or facial scrubs in the week before your peel. Don't shave the areas that will be treated beginning 24 hours before your peel.
• Arrange for a ride home. If you'll be sedated during the procedure, arrange for a ride home.
