Key takeaways
- A chemical peel is a solution applied to the skin to remove its outer layers, revealing smoother, brighter skin.
- There are three depths, light, medium and deep; the deeper the peel, the stronger the result and the longer the healing.
- A light peel usually needs 3 to 5 sessions, and the skin heals within a week.
- Darker skin needs an experienced dermatologist to avoid permanent pigment problems.
- Daily sunscreen after a peel is essential to protect the result.
What do chemical peels treat?
- Some types of acne.
- Age spots and freckles.
- Melasma and uneven skin tone.
- Dull, rough-feeling skin.
- Fine lines, especially under the eyes and around the mouth.
- Sun damage, and some precancerous growths (actinic keratoses).
What types of peels are there?
| Type | Healing | Sessions | Notes |
|---|---|---|---|
| Light (superficial) | 1 to 7 days | 3 to 5 peels every 2 to 5 weeks | Best for dull skin, mild spots and acne |
| Medium | 7 to 14 days | Can be repeated as your doctor advises | Needs an antiviral medicine for 10 to 14 days |
| Deep | 14 to 21 days, with 2 to 3 weeks at home | Only one in a lifetime | Needs an antiviral and total sun avoidance for 3 to 6 months |
How to prepare for a peel
- Your doctor may set a 2- to 4-week skin care plan to prepare your skin.
- Tell your doctor if you get cold sores (herpes); an antiviral may be prescribed.
- Share all your medicines and topical products, especially retinoids and exfoliants.
- Avoid tanning before the session.
After the peel
- Follow aftercare instructions closely, and don't pick at peeling skin.
- Once your skin heals, apply sunscreen every day.
- After a deep peel, avoid the sun completely for 3 to 6 months.
What are the possible risks?
- Redness that lasts longer than expected.
- Temporary darkening of the skin.
- Lightening of the skin.
- Scarring, which is very rare.
Peels and darker skin
Brown and darker skin can benefit from peels, especially for spots and melasma, but is more prone to pigment problems if a peel is stronger than needed. Choosing the peel type and strength calls for a dermatologist experienced with darker skin, to avoid pigment problems that can be permanent.
Can I peel at home?
Mild at-home exfoliating products are one thing; medical peels are another. The U.S. Food and Drug Administration warns to use chemical peels only with professional supervision, because at-home products have caused serious injuries.
If the goal is to treat melasma, scars or dark spots, a peel should be part of a medical plan, not a home experiment.
Common questions
- Will my face visibly peel? With a light peel there's usually only mild flaking; peeling increases with medium and deep peels.
- Does it help melasma? Yes, as part of a plan, but melasma also needs daily sunscreen and topical treatment.
- Is it covered by insurance? Usually not, as it's considered cosmetic.
