Chemical peel

A chemical peel is a procedure in which a chemical solution is applied to the skin to remove the top layers. The skin that grows back is smoother. With a light or medium peel, you may need to undergo the procedure more than once to get the desired results. Chemical peels are used to treat wrinkles, discolored skin and scars — usually on the face. They can be done alone or combined with other cosmetic procedures. And they can be done at different depths, from light to deep. Deeper chemical peels offer more-dramatic results but also take longer to recover from.

A chemical peel is a skin-resurfacing procedure. Depending on the issues you're addressing with the procedure, you'll choose a chemical peel in one of three depths: Light chemical peel. A light (superficial) chemical peel removes the outer layer of skin (epidermis). It's used to treat fine wrinkles, acne, uneven skin tone and dryness. You might have a light peel every two to five weeks. Medium chemical peel. A medium chemical peel removes skin cells from the epidermis and from portions of the upper part of your middle layer of skin (dermis). It's used to treat wrinkles, acne scars and uneven skin tone. You might need to repeat the procedure to achieve or maintain the desired result. Deep chemical peel. A deep chemical peel removes skin cells even deeper. Your doctor might recommend one for deeper wrinkles, scars or precancerous growths. You won't need repeat procedures to get the full effect. Chemical peels can't remove deep scars or wrinkles or tighten sagging skin.

A chemical peel can cause various side effects, including: Redness, scabbing and swelling. Normal healing from a chemical peel involves redness of the treated skin. After a medium or deep chemical peel, redness might last for a few months. Scarring. Rarely, a chemical peel can cause scarring — typically on the lower part of the face. Antibiotics and steroid medications can be used to soften the appearance of these scars. Changes in skin color. A chemical peel can cause treated skin to become darker than normal (hyperpigmentation) or lighter than normal (hypopigmentation). Hyperpigmentation is more common after superficial peels, while hypopigmentation is more common after a deep peel. These problems are more common in people with brown or black skin and can sometimes be permanent. Infection. A chemical peel can lead to a bacterial, fungal or viral infection, such as a flare-up of the herpes virus — the virus that causes cold sores. Heart, kidney or liver damage. A deep chemical peel uses carbolic acid (phenol), which can damage heart muscle and cause the heart to beat irregularly. Phenol can also harm the kidneys and liver. To limit exposure to phenol, a deep chemical peel is done a portion at a time, in 10- to 20-minute intervals. A chemical peel isn't for everyone. Your doctor might caution against a chemical peel or certain types of chemical peels if you: Have taken the oral acne medication isotretinoin (Myorisan, Claravis, others) in the past six months Have a personal or family history of ridged areas caused by an overgrowth of scar tissue (keloids) Are pregnant Have frequent or severe outbreaks of cold sores

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.
