Chemical peels are the third most popular non-invasive cosmetic procedure worldwide, with over 1.3 million treatments performed annually in the US alone. But with so many types and brands available, how do you know which one is right for your skin?
How Chemical Peels Work
A chemical peel applies a controlled acid solution to the skin, causing a precise, measured injury. This triggers your body's natural healing response: within 5 minutes, inflammation begins. By day 9, a remodeled collagen network is already visible under microscopy — without any remaining inflammatory cells.
The process stimulates new collagen and elastin production, reorganizes structural proteins, and regenerates fresh skin cells. This collagen remodeling can continue for 6-12 months after treatment.
Three Depths of Peeling
Superficial Peels
These work on the epidermis (outer skin layer) using acids like glycolic acid, salicylic acid, lactic acid, or mandelic acid. Downtime is minimal — mild redness for 1-3 days. Ideal for acne, dull skin, mild pigmentation, and maintenance.
Medium-Depth Peels
Using higher-concentration TCA (trichloroacetic acid) or combination formulas, these penetrate into the papillary dermis. Expect 7-14 days of recovery with peeling and redness. Best for sun damage, fine lines, and deeper pigmentation issues.
Deep Peels
Phenol-based peels reach the mid-dermis for dramatic results, but with 2-3 weeks of downtime and only suitable for lighter skin types (Fitzpatrick I-III).
What Does the Research Say?
For Acne
A systematic review of 12 randomized controlled trials found that glycolic acid peels are 2.3 times more likely to produce excellent results compared to placebo. Combined salicylic-mandelic acid peels performed even better, achieving 85% improvement versus 69% for glycolic acid alone.
For Melasma (Pigmentation)
The most comprehensive study to date — a 2024 systematic review of 24 studies with 1,075 patients — confirmed glycolic acid as the safest and most effective chemical peel for melasma treatment.
For Acne Scars
When combined with microneedling, chemical peels become dramatically more effective. A 120-patient double-blind study found the combination was 5-9 times more effective than either treatment alone for atrophic acne scars.
Safety Across Skin Types
Superficial peels are safe for all skin types, including darker skin (Fitzpatrick IV-VI). A study of 473 treatments in darker-skinned patients found only a 3.8% complication rate with superficial peels. However, deeper peels require extra caution with darker skin types due to higher pigmentation risk.
Our Peel Portfolio at ihohud
We offer three professional peel brands, each with distinct strengths:
- Dermaceutic — French laboratory specializing in aesthetic dermatology. Their Cosmo Peel Forte showed 94% wrinkle reduction in a 63-patient study. The Milk Peel achieved 92% improvement in skin luminosity after just 2 treatments.
- Eneomey — 30+ years of glycolic acid expertise. Their precisely dosed formulas leverage the extensive clinical evidence for glycolic acid — the most studied peel ingredient available.
- SkinCeuticals — Part of L'Oreal's active cosmetics division. Their Advanced Corrective Peel delivered 31% improvement in skin tone and 45% in texture in a dermatologist-controlled study of 37 patients.
Having multiple options means we can match the right peel to your specific skin concern — not a one-size-fits-all approach.
What to Expect
Most superficial peels involve zero downtime — you can return to normal activities the same day. Peak peeling typically occurs on days 3-4. Your skin specialist will recommend the right depth and frequency based on your skin type, concerns, and lifestyle.
