How it works
A chemical peel uses an acid to loosen and remove the top layers of skin. Your body then makes fresh skin to take their place. This new skin is often smoother and more even in tone.
Peels come in three depths: light, medium, and deep. The deeper the peel, the bigger the results, but also the longer the healing and the higher the risk.
Superficial (light) peels. These use gentle acids like glycolic acid, salicylic acid, or azelaic acid. They help with mild acne, dullness, and light dark spots, with just a few days of flaking.
Medium peels. These usually use TCA and reach deeper to treat stronger pigment, sun damage, fine lines, and some acne scars. Expect redness and peeling for about a week.
Deep peels. These use phenol, the strongest option, for deep wrinkles and heavy sun damage. Healing takes two weeks or more and they are used less often today.
What to expect
Before. Your provider reviews your skin, health, and any medicines. You may need to stop certain products, like retinoids, for a few days first.
During. The skin is cleaned, then the acid is brushed on and left for a set time. You may feel stinging or warmth. Light peels take just a few minutes.
After. The skin looks red and may feel tight, then flakes and peels over a few days. Do not pick or scrub. Sun protection is a must — new skin burns easily, so wear broad-spectrum SPF 30+ every day.
Side effects & risks
- Redness, tightness, and peeling for several days
- Temporary darkening or dark spots (post-inflammatory hyperpigmentation), more common in darker skin tones
- Dryness and mild swelling
- Rare but serious: scarring, infection, or lasting color change
Who it's not for
Chemical peels may not be safe with an active skin infection, an open sore, or a cold sore outbreak. Tell your provider if you recently took isotretinoin, since peels are usually delayed for several months after. Peels are often postponed during pregnancy. Medium and deep peels carry a higher risk of pigment changes in darker skin tones.
Frequently asked questions
Q: Does it hurt?
A: Light peels cause mild stinging that fades fast. Deeper peels feel more intense, so your provider may use numbing cream.
Q: Are peels safe for dark skin?
A: Light peels are generally safe when done by a trained provider. Medium and deep peels carry a higher risk of dark spots, so gentler peels are often better.
Q: How long until I see results?
A: Most people see brighter, smoother skin 1–2 weeks after peeling stops.
Q: How often can I get a peel?
A: Light peels every 2–4 weeks; medium peels months apart; deep peels usually once.
