A chemical peel is a skin-resurfacing procedure in which a chemical solution is applied to the skin to remove the top layers. The skin that grows back after a chemical peel is smoother and younger looking.
Chemical peels are used to treat wrinkles, skin discoloration and scars — typically on the face. A chemical peel can be done alone or in combination with other cosmetic procedures.
Chemical peels can be done at different depths — light, medium or deep — depending on your desired results. Each type of chemical peel uses a different chemical solution. Deeper chemical peels produce more-dramatic results, but also involve longer recovery times.
Why it’s done
A chemical peel can be used to treat various skin problems. 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, or superficial, chemical peel removes the outer layer of skin (epidermis). It can be used to treat fine wrinkles, acne, uneven skin tone and dryness. You might have a light chemical peel as often as once a week for up to six weeks — depending on your desired results.
- Medium chemical peel. This type of chemical peel removes skin cells from the epidermis and from portions of the upper part of your middle layer of skin (dermis). A medium chemical peel can treat wrinkles, acne scars and uneven skin tone. You might repeat a medium chemical peel after 12 months to maintain results.
- Deep chemical peel. A deep chemical peel removes skin cells from the epidermis and from portions of the mid to lower layer of your dermis. Your doctor might recommend a deep chemical peel if you have deeper wrinkles, scars or precancerous growths.
A chemical peel can’t eliminate deep scars or reduce the size of pores.
A chemical peel can cause various side effects, including:
- Redness. Normal healing from a chemical peel involves redness of the treated skin. After a medium or deep chemical peel, redness might last for several 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. Changes in skin color are more common in people who have darker skin and can be permanent.
- Infection. A chemical peel can cause a flare-up of the herpes virus — the virus that causes cold sores. Rarely, a chemical peel can lead to a bacterial or fungal infection.
- Heart, kidney or liver damage. A deep chemical peel uses carbolic acid (phenol), which can damage the 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 in portions at 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 acne medication isotretinoin (Amnesteem, others) in the past six months
- Have a dark complexion
- Have red hair and a pale, freckled complexion
- Have a personal history of ridged areas caused by an overgrowth of scar tissue (keloids)
- Have abnormal skin pigmentation
- Have facial warts
- Have a history of frequent or severe outbreaks of cold sores
What you can expect
A chemical peel is typically done in an office-based procedure room or outpatient surgical facility. Before the procedure, your doctor will clean your face and might cover your eyes with ointment, gauze, tape or goggles. He or she might also protect your hair.
Pain relief isn’t typically needed for a light chemical peel. If you’re having a medium chemical peel, you might have the option of taking a sedative and a painkiller.
If you’re having a deep chemical peel, your doctor will likely numb your skin with a local anesthetic and give you a sedative or use regional anesthesia — which numbs a certain part of your body.
During the procedure
During a light chemical peel:
- Your doctor will use a brush, cotton ball, gauze or sponge to apply a chemical solution typically containing glycolic acid or salicylic acid. The treated skin will begin to whiten.
- You might feel mild stinging while the chemical solution is on your skin.
- Your doctor will apply a neutralizing solution or wash to remove the chemical solution from the treated skin.
During a medium chemical peel:
- Your doctor will use a cotton-tipped applicator or gauze to apply a chemical solution containing trichloroacetic acid, sometimes in combination with glycolic acid. The treated skin will begin to whiten.
- After a few minutes, your doctor will apply cool compresses to soothe treated skin. You might also be given a hand-held fan to cool your skin. No neutralizing solution is needed, however.
- You might feel stinging and burning for up to 20 minutes.
During a deep chemical peel:
- You’ll be given intravenous (IV) fluids, and your heart rate will be closely monitored.
- Your doctor will use a cotton-tipped applicator to apply carbolic acid (phenol) to your skin. Treated skin will begin to turn white or gray.
- To limit your exposure to phenol, your doctor will do the procedure in portions at about 15-minute intervals. A full-facial procedure might take about 90 minutes.
After the procedure
After a chemical peel of any depth, follow your doctor’s directions for cleansing, moisturizing and applying protective ointments to your skin.
After a light chemical peel, treated skin will be red, dry and mildly irritated — although these effects might be less noticeable with each repeat treatment. Your doctor might apply a protective ointment, such as petroleum jelly, to soothe the area.
Treated areas develop new skin about four to seven days after a light chemical peel. New skin might temporarily be lighter or darker than normal.
After a medium chemical peel, treated skin will be red, tight and swollen. You’ll feel stinging. Your doctor might apply a protective ointment, such as petroleum jelly, to soothe the area.
Use ice packs or the breeze from a fan for comfort. Over-the-counter pain-relieving medication, such as ibuprofen (Advil, Motrin IB, others) and naproxen sodium (Aleve, others), may help reduce any discomfort. You’ll likely schedule a checkup soon after your treatment so that your doctor can monitor your healing.
As swelling decreases, treated skin will begin to form a crust and might darken or develop brown blotches. Treated areas develop new skin about five to seven days after a medium chemical peel, but redness might last for months.
After a deep chemical peel, you’ll experience severe redness and swelling. You’ll also feel burning and throbbing, and your eyelids might swell shut.
Your doctor will apply a watertight dressing to treated skin. He or she might also prescribe painkillers. Sleeping in a semireclined position may help reduce swelling.
Treated areas will develop new skin within about two weeks after a deep chemical peel, although cysts or white spots might appear for several weeks and redness might last for months. Treated skin might become darker or lighter than normal or lose the ability to tan.
You might prefer to remain at home while you’re healing from a chemical peel. Once new skin completely covers the treated area in about two weeks, you can use cosmetics to conceal any redness.
