Dermamelan vs Cosmelan: Which Melasma Peel Should You Actually Use?
Dermamelan and Cosmelan both target melasma with phase 1 clinic mask + phase 2 home cream. Dermamelan is stronger. Here is who should choose each, with results and precautions.
Quick Verdict
Dermamelan and Cosmelan are both two-phase depigmentation protocols from mesoestetic — a phase 1 in-clinic mask (4-8 hours) followed by a phase 2 at-home maintenance cream for 60-180 days. Cosmelan is designed for skin that does not tolerate strong actives — milder, broader-indication, suitable for first-time melasma treatment. Dermamelan is the medical-grade upgrade — stronger formulation (higher active concentrations, typically including hydroquinone), prescribed for moderate-to-severe melasma or for patients who failed Cosmelan. Both protocols require strict sun protection and should only be administered by experienced providers.

How the Protocols Work
Both follow the same two-phase architecture:
Phase 1 — in-clinic mask
The provider cleanses the skin, applies the Cosmelan or Dermamelan mask thinly and uniformly across affected zones, and you wear it home for 8-12 hours. You return to the clinic (or follow home instructions) to remove the mask with a gentle cleanser. Over the next 3-10 days, treated skin darkens, then flakes and peels, revealing lighter skin underneath. This is the controlled chemical injury that removes existing pigment.
Phase 2 — at-home maintenance
For 60-180 days afterwards you apply the Cosmelan 2 or Dermamelan maintenance cream twice daily (gradually tapering to once daily). This phase is the mechanism that prevents melanin recurrence — you're not just stripping pigment, you're suppressing the melanocytes that would otherwise re-deposit it within weeks.
The maintenance phase is where most treatment failures happen — patients stop the home cream at 6 weeks because the visible result looks great, then melasma recurs at 3-6 months.
Key Differences
Active concentration
Cosmelan's active complex includes azelaic acid, kojic acid, arbutin, phytic acid, and niacinamide — all tyrosinase inhibitors. Dermamelan adds higher concentrations plus hydroquinone (a direct tyrosinase-complex disruptor), which is why it requires a dermatologist prescription and is not sold OTC.
Depth of effect
Cosmelan works in the epidermis and superficial dermis. Dermamelan reaches deeper and addresses mixed or dermal-component melasma better, at the cost of higher post-inflammatory hyperpigmentation (PIH) risk.
Recovery
Cosmelan's phase 1 visible downtime is 3-5 days of flaking. Dermamelan's is 5-10 days and more intense.
Suitability
Cosmelan is the first-line choice for a patient new to melasma treatment. Dermamelan is for patients whose melasma has resisted multiple prior treatments (topical tranexamic, hydroquinone, Cosmelan).
When to Pick Cosmelan
- First melasma-specific treatment (after SPF and OTC topicals)
- Mild-moderate epidermal melasma (Wood's lamp pattern positive)
- Fitzpatrick I-II where PIH risk is lower
- Wedding / event 3-6 months away with stable treatment plan
- Patient who cannot tolerate prescription hydroquinone
When to Pick Dermamelan
- Moderate-severe melasma
- Previously failed Cosmelan or topical hydroquinone
- Mixed epidermal + dermal component melasma
- Patient who will commit to 90+ days of maintenance cream
- Dermatologist-supervised environment (not esthetician-only)
Who Should NOT Get Either
- Pregnancy or breastfeeding (both contraindicated)
- Active inflammatory skin conditions (rosacea flare, eczema, acne flare)
- Recent (within 6 months) isotretinoin use
- Planned sun exposure in the 3 months post-treatment without strict SPF 50 plus iron oxide
- Patients unwilling to commit to 60-180 days of home maintenance cream
- Fitzpatrick V-VI without provider experience in darker skin
Post-Treatment Sunscreen Protocol
Both Cosmelan and Dermamelan require strict sun protection for 3+ months post-peel. Without it, melasma recurs reliably within weeks. Specific requirements:
- SPF 50+ mineral sunscreen (zinc + titanium) with iron oxide tinting
- Reapplication every 2 hours outdoors and every 4 hours indoors near windows
- Wide-brim hat during peak hours
- Avoid direct sun exposure for the first 14 days post-peel
- Avoid saunas, hot yoga, and heat exposure for 14 days
Frequently Asked Questions
Is Dermamelan stronger than Cosmelan?
Yes. Dermamelan contains higher concentrations of tyrosinase inhibitors plus hydroquinone (not in Cosmelan), reaches deeper into the dermis, and is reserved for moderate-severe melasma or patients who failed Cosmelan. The stronger formulation means better clearance for stubborn melasma but higher PIH risk and longer downtime.
Which is safer, Cosmelan or Dermamelan?
Cosmelan has the lower-risk profile — no prescription actives, lower PIH risk, shorter downtime, and appropriate for most skin types. Dermamelan requires dermatologist supervision and is specifically for patients where Cosmelan was insufficient. For first-time melasma treatment, Cosmelan is the safer starting point.
How long do Dermamelan and Cosmelan results last?
With adherent maintenance (phase 2 home cream for 60-180 days) plus strict sun protection, results typically last 12-24 months before a touch-up peel is needed. Without maintenance, melasma recurs within 3-6 months — the phase 2 cream is what makes the protocol durable.
Can you get Dermamelan or Cosmelan while pregnant?
No. Both protocols are contraindicated in pregnancy and breastfeeding. Pregnancy-safe melasma options are limited to azelaic acid 15-20% and strict sun protection with iron-oxide mineral SPF. Most pregnancy-related melasma (chloasma) fades spontaneously postpartum; aggressive treatment can resume 6-8 weeks after breastfeeding ends.
Bottom Line
Cosmelan is the starting protocol for most melasma patients. Dermamelan is the medical-grade upgrade for moderate-severe or treatment-resistant cases. Neither works without strict phase-2 maintenance and sun protection. Choose based on severity, skin-type tolerance, and whether you have a dermatologist willing to prescribe the stronger formulation.
