Chemical peels can fade many kinds of hyperpigmentation. They work best on sun spots, freckles and flat dark marks left by acne or irritation. Melasma responds too, but it needs prescription creams and daily sun protection alongside the peels, and it can come back.
The key is matching the peel to the type of pigment and to your skin tone. This guide shows you how.
Which type of hyperpigmentation do you have?
| Type | What it looks like | Common causes | How well peels work | What else helps |
|---|---|---|---|---|
| Sun spots (age spots) | Flat tan or brown spots on the face, hands and chest | Years of sun exposure | Often well, over a series | Laser for brown spots for stubborn spots |
| Freckles | Small light brown spots that darken in summer | Genes and sun | They lighten, but return with sun | Daily sunscreen |
| Melasma | Brown or gray-brown patches on the cheeks, forehead or upper lip | Sun, hormones such as pregnancy or birth control pills, some medicines | A helpful add-on, not a cure | Prescription creams, sun protection, sometimes tranexamic acid |
| Post-inflammatory hyperpigmentation | Flat dark marks where a pimple, rash or injury healed | Inflammation from acne, eczema, bites or cuts | Often well, once the cause is treated | Treating the cause, sunscreen, fading creams |
Not sure which you have? A dermatologist can usually tell by looking closely at your skin, sometimes with a special light that shows how deep the pigment sits.
Which chemical peel is best for hyperpigmentation?
There’s no single best peel. The right one depends on the type of pigment, how deep it sits and your skin tone.
| Peel | Best for | Good to know |
|---|---|---|
| Glycolic acid | Melasma, sun spots, uneven tone | The best-studied peel for melasma. A 2024 review of 24 studies found it the safest and most effective option. |
| Salicylic acid | Dark marks on oily or acne-prone skin | Also treats the breakouts that cause new marks |
| Lactic acid | Sensitive or dry skin | Gentler, with less flaking |
| Kojic acid and glutathione | Brightening and uneven tone | Trillium’s brightening peels. Kojic acid is one of the fading ingredients the AAD lists. |
| TCA (moderate strength) | Stubborn sun spots | More peeling and downtime. Used with more caution on darker skin. |
| VI Peel | Pigment mixed with texture or acne | A blended medical-grade peel |
At Trillium, board-certified dermatologist Dr. Stefan Weiss performs every peel himself. He offers mild to moderate peels, including all of the above, and every peel starts mild and steps up as your skin allows.
Chemical peels for melasma: what to expect
The American Academy of Dermatology says there’s no one best treatment for melasma. A typical plan includes:
- Sun protection every day. A broad-spectrum SPF 30+ with zinc oxide, titanium dioxide or iron oxide, plus a wide-brimmed hat.
- A prescription cream. Often hydroquinone, a triple combination cream, or gentler options like azelaic acid, kojic acid or vitamin C.
- A procedure, if needed. Chemical peels are one of the options dermatologists add when creams alone aren’t enough.
Results usually take 3 to 12 months. Melasma often returns with sun or hormone changes, so most people need ongoing care. See our melasma treatment page and melasma guide for the full picture.
How many chemical peels do you need?
Most people need a series. At Trillium, 4 to 8 peels spaced 10 to 14 days apart is typical. The AAD notes that light peels often take 3 to 5 sessions.
Some people follow a skin care plan for 2 to 4 weeks before the first peel. It can improve results and lower the risk of side effects. Results build over the series, and sun spots and freckles can come back without daily sun protection.
How to avoid new dark spots after a peel
A peel can temporarily darken the skin, and existing dark spots may look darker while your skin peels. That usually fades as the skin heals. To lower the risk of new pigment:
- Wear sunscreen daily. A tinted SPF 30+ with iron oxide also blocks visible light.
- Don’t pick or peel flaking skin. Picking can leave new dark marks.
- Wait to restart your usual products. Most people go back to their normal routine after about day 7.
- Skip saunas, hot tubs and very hot water until peeling stops.
If darker patches haven’t faded within a few weeks, let us know. They usually respond to fading creams and sun protection. Full aftercare steps are on our treatment instructions page.
If you have darker skin
Medium and darker skin tones get hyperpigmentation more often, and they’re more likely to form new dark spots after irritation. Mild peels, a slow step-up and daily sunscreen keep that risk low. The AAD advises seeing someone experienced with darker skin, because the wrong peel can cause lasting pigment problems. Read our guide to chemical peels for skin of color.
If your dark spots are from acne, see chemical peels for acne scars and dark marks.
Why at-home peels are risky
In July 2024 the FDA warned against buying or using chemical peel products without professional supervision. Some products sold online contain acid levels too high to use safely at home and have caused serious skin injuries. On skin prone to pigment, a burn can leave dark patches that last longer than the spots you started with.
