A clear breakdown of chemical peel types, what they treat, what recovery looks like, and how to decide whether a light, medium, or deep peel is appropriate for your goals.

Chemical peels are one of the oldest aesthetic treatments that still holds up. Here's how to understand the tiers — and how to choose the right one without getting oversold.
A chemical peel applies an acid solution to the skin to accelerate exfoliation and stimulate collagen production. How deep the peel penetrates the skin determines both the results and the recovery. The three broad tiers:
| Peel depth | Examples | Targets | Recovery |
|---|---|---|---|
| Superficial | Glycolic (20–35%), lactic, mandelic | Texture, mild discoloration, dullness | Minimal; slight flaking 2–3 days |
| Medium | TCA 20–35%, Jessner's solution | Acne scars, fine lines, uneven pigment | 5–7 days of peeling/crusting |
| Deep | TCA 50%+, phenol | Deep wrinkles, significant scarring | 10–14 days; medical supervision required |
Light peels are what most aestheticians perform. They remove the outermost layer of the epidermis, leaving skin temporarily smoother and brighter. Results are real but subtle — you typically need a series of 4–6 treatments spaced 2–4 weeks apart to see meaningful change.
Good for:
What to expect: Tingling or mild stinging during application, slight pinkness for a day, and light flaking over the next 2–3 days. Most people return to work the same day.
Medium peels reach the upper dermis, where collagen remodeling happens. TCA (trichloroacetic acid) at 20–35% is the standard. Jessner's solution is often layered underneath to prime the skin and improve TCA penetration.
Good for:
What to expect: More significant "frosting" (the whitening you see during application), followed by 5–7 days of progressive peeling and temporary darkening. You'll look like you have a sunburn for the first 1–2 days, then your skin will visibly peel — plan to avoid social obligations. SPF 30+ is non-negotiable for 6–8 weeks after.
Melasma caveat: TCA can worsen melasma if the wrong concentration is used or sun protection lapses. Always disclose melasma history.
Phenol peels are the most aggressive option and are performed by physicians, typically under mild sedation. Results can be dramatic for deep wrinkles and significant photoaging — but so is the recovery: two weeks of significant redness and crusting, several months until full normalization.
Deep peels are rarely performed as a standalone offering at a standard med spa. If a non-physician clinic is offering "deep" phenol peels, ask hard questions.
Chemical peels carry a real risk of post-inflammatory hyperpigmentation (PIH) and hypopigmentation, particularly in skin types Fitzpatrick III–VI. Darker skin types can still benefit from chemical peels — but the acid type, concentration, and timing need to be carefully calibrated.
Mandelic acid (a gentler AHA) and lower-concentration lactic acid peels are generally safer starting points for melanin-rich skin. Jessner's/TCA medium peels are possible but require an experienced provider.
| Peel type | Average per session | Typical series |
|---|---|---|
| Superficial | $75–$200 | $300–$900 (series of 4–6) |
| Medium (TCA) | $200–$500 | Usually single session or 2–3 |
| Deep (phenol) | $1,000–$3,000 | Single session |
