What is a chemical peel?
A chemical peel is a skin resurfacing procedure where a provider applies an acid solution to your face, causing controlled exfoliation of the outer layers. The treated skin peels off over several days. What grows back is smoother, more even-toned and less visibly damaged.
The procedure has been around for over a century. It's still one of the most cost-effective resurfacing options in aesthetics. The American Society of Plastic Surgeons reported over 1.4 million chemical peel treatments in the US in 2023, putting it in the top five nonsurgical cosmetic procedures that year.
Types of chemical peels by depth
Peels fall into three depth categories. Which one you need depends on your skin concerns, your Fitzpatrick type, how much downtime you can handle and what you're trying to fix.
Superficial (light) peels
These target only the epidermis. They're the gentlest option, good for first-timers and for maintenance between deeper treatments. Common acids:
- Glycolic acid (20-50%): An AHA derived from sugarcane. Works on dullness, fine lines and mild discoloration. It's the most widely used peel acid by a wide margin.
- Salicylic acid (20-30%): A BHA that's oil-soluble, so it actually gets into pores. That makes it the go-to for acne-prone and oily skin.
- Lactic acid (30-50%): A gentler AHA that also hydrates. Good for sensitive skin and people who've never had a peel.
- Mandelic acid (30-50%): A larger-molecule AHA that absorbs more slowly and evenly. Better tolerated by darker skin tones, with lower risk of post-inflammatory hyperpigmentation.
Recovery is minimal. Mild redness and light flaking for 1 to 3 days. Most people wear makeup and go about their day.
Medium-depth peels
These penetrate through the epidermis into the upper dermis. More downtime, but noticeably better results. The primary agent:
- Trichloroacetic acid (TCA) at 25-35%: The workhorse here. Treats moderate sun damage, deeper wrinkles, acne scars and melasma. A 2010 study in the Indian Journal of Dermatology (n=40) found 70% of patients achieved "good" or "very good" improvement in acne scars after three TCA peels at 25%.
- Jessner's solution + TCA combination: Jessner's (a mix of salicylic acid, lactic acid and resorcinol) is applied first to boost penetration of a lower-concentration TCA peel. The idea is medium-depth results with less irritation.
Recovery: 5 to 10 days of visible peeling, redness and sensitivity. Most patients take a day or two off work. Strict sun avoidance for 2 to 4 weeks after.
Deep peels
These reach the mid-reticular dermis. Results are dramatic. So is recovery. Most people get a deep peel once in their life, maybe twice.
- Phenol (Baker-Gordon formula): The strongest chemical peel that exists. Phenol can dramatically improve deep wrinkles, severe sun damage and pre-cancerous growths, with results lasting years. But phenol is cardiotoxic at systemic levels. Treatment requires cardiac monitoring and should only be done by an experienced dermatologist or plastic surgeon in a medical setting. (The Baker-Gordon formula hasn't changed much since 1961.)
- High-concentration TCA (50%+): Sometimes used instead of phenol for targeted deep peeling of specific areas, though scarring risk goes up substantially at these concentrations.
Recovery: 2 to 3 weeks of heavy peeling, crusting, swelling and redness. Full redness resolution can take 2 to 3 months. Sun avoidance for 3 to 6 months. Deep peels aren't recommended for darker skin types (Fitzpatrick IV-VI) because of the high risk of permanent pigment changes.
Cost comparison by peel depth
We pulled this pricing from 18,000+ verified providers across 1,000+ cities in our directory. In Manhattan, expect to pay toward the top of each range; in Phoenix or Dallas, closer to the bottom. Use provider search to compare costs near you.
| Peel Type | Active Ingredient | Cost Per Treatment | Sessions Recommended | Total Series Cost |
|---|---|---|---|---|
| Superficial (light) | Glycolic, salicylic, lactic acid | $150 - $300 | 4 - 6 (monthly) | $600 - $1,800 |
| Medium | TCA 25-35%, Jessner's + TCA | $300 - $1,000 | 1 - 3 (6-12 weeks apart) | $300 - $3,000 |
| Deep | Phenol, high-concentration TCA | $1,500 - $3,000+ | 1 (lifetime, rarely 2) | $1,500 - $3,000+ |
Who is a good candidate?
If any of these describe your skin, a peel is probably worth considering:
- Uneven skin tone: Sunspots, age spots, melasma and post-acne dark marks respond well to glycolic and TCA peels.
- Fine lines and wrinkles: Superficial to medium peels improve fine lines. Deep peels can soften more established wrinkles.
- Acne and acne scars: Salicylic acid peels work for active breakouts. TCA peels at medium depth can improve the texture of shallow acne scars.
- Rough or dull texture: Regular superficial peels keep things smooth. That's basically the whole job.
- Sun damage: Peels reverse photoaging by removing damaged surface cells and triggering collagen production underneath.
Patients with darker skin tones (Fitzpatrick IV-VI) need to be careful. Deeper peels carry real risk of post-inflammatory hyperpigmentation or permanent pigment changes. Superficial peels and mandelic acid are generally safer. A 2013 study in the Journal of Clinical and Aesthetic Dermatology (n=25) found mandelic acid peels produced better outcomes for melasma and PIH in darker skin types than glycolic acid, with fewer adverse events.
Chemical peels are one of the few treatments in aesthetics where a $200 procedure can deliver results that rival a $2,000 laser — if you pick the right acid, the right depth, and the right provider for your skin type.
What to expect during and after a peel
Here's the actual timeline:
- During the peel: Your provider cleanses the skin, applies the acid and watches the clock. You'll feel tingling, warmth or stinging depending on concentration. Superficial peels take 5 to 10 minutes; medium peels 15 to 20; deep peels can run 30 to 60 minutes.
- Right after: Redness like a sunburn. For superficial peels, it fades within hours. Medium and deep peels mean real redness and swelling.
- Days 2-5: Peeling starts. Light flaking for superficial peels. Visible sheets of skin for medium. Crusting for deep.
- Days 7-14: Most peeling wraps up for superficial and medium peels. Deep peels may keep going for 2 to 3 weeks.
- Aftercare: Don't pick at peeling skin. Seriously, don't. That's how you get scars. Moisturize, wear SPF 30+ daily and stay out of direct sun during recovery.
Chemical peels vs other resurfacing treatments
| Treatment | Best For | Cost | Downtime |
|---|---|---|---|
| Chemical peel (medium) | Pigmentation, texture, fine lines | $300 - $1,000 | 5-10 days |
| Microneedling | Scars, pores, collagen stimulation | $200 - $700 | 2-5 days |
| Ablative laser | Deep wrinkles, scars, sun damage | $1,200 - $3,000+ | 1-3 weeks |
| Microdermabrasion | Mild dullness, very fine lines | $100 - $250 | None to 1 day |

Finding a provider
Because chemical peels involve acid on your face, provider experience matters more than price. And deep peels specifically need to be done in a medical setting with cardiac monitoring. Search our provider directory to compare credentials and pricing near you.
