Melasma: control it now, and the long-term plan
Melasma is not cured — it is put into remission, and kept there. Here is how I think about it: what it is, what actually works, the numbers, and the long-term plan.
What melasma is — and why it behaves the way it does
Melasma is a chronic pigment condition producing symmetrical brown patches, typically across the cheeks, forehead and upper lip. It is driven by three forces working together: hormones (pregnancy, the pill, HRT — systemic oestrogen carries more risk than topical), light (not just UV — visible light and infrared heat flare melasma, which is why ordinary sunscreen isn't enough), and genetics. It can be epidermal (superficial), dermal (deeper and more resistant), or mixed. It is not dangerous and never becomes skin cancer — but it is relentless if managed casually.
Step one: photoprotection — where 95% of patients go wrong
- Tinted SPF 50+ is mandatory — the iron oxides in the tint block the visible light that untinted sunscreen lets straight through.
- Dose properly: two finger-lengths (3–5 mL) for face and neck, at least twice daily. If you can't faintly see it on your skin, you haven't applied enough.
- Outdoor and active patients: reapply every 2 hours (hourly when swimming or surfing); tinted sunscreen sticks make reapplication a 10–20 second job. A 50 mL bottle should last weeks, not months — which is exactly why the questionnaire asks.
- Layers behind the sunscreen: topical antioxidants (vitamin C/E/ferulic), oral Polypodium leucotomos 480 mg daily, and vitamin D supplementation to offset the sun you're now avoiding.
- Heat is the trap: infrared is NOT blocked by sunscreen. Saunas, hot kitchens and hot climates flare heat-sensitive melasma regardless of SPF.
The numbers make the point: treatment success is roughly 85% in patients who get protection right, 75–80% for active outdoor patients, 50% for heat-activated melasma — and 20% for non-compliant patients. Same treatments; the difference is the foundation.
Step two: pigment suppression
A supervised, rotated program of pigment inhibitors — entry-level actives (azelaic acid, niacinamide, kojic acid, arbutin, vitamin C) stepping up to cysteamine or compounded prescription creams, with a prescription oral or topical agent where suitable. The evidence is encouraging: triple-combination prescription cream cleared or nearly cleared melasma in ~70% of patients at 8 weeks; azelaic acid 15–20% and niacinamide 4% each perform comparably to the prescription-strength standard with fewer side effects.
Step three: pigment removal — with the right devices only
| Treatment | Typical course | Realistic result |
|---|---|---|
| Picosecond laser | 4 sessions, no downtime | 80–85% clearance — my workhorse; effective across skin types, low flare risk |
| Novel peels (Vi Precision Plus / Cosmelan) | 1 treatment + aftercare | 55–60% / 60%+ clearance; Cosmelan carries 7–14 days of recovery and common irritation |
| Traditional AHA peels | Series | 20–30% clearance — gentle, modest |
| Fractional thulium laser | 6–8 sessions | Used for dermal remodelling toward remission; flares possible |
| IPL | — | Avoid — flares melasma in the vast majority of cases |
| Aggressive heat-based fractional lasers | — | Avoid — excess heat is a melasma trigger |
Overall, 80–85% of patients respond to properly sequenced combination therapy (more than half the pigment cleared). Poor responders share a pattern: deep dermal pigment, outdoor work, poor sunscreen compliance.
The long-term solution: dermal remodelling
Clearing pigment is not the same as keeping it away — most melasma recurs somewhere between 4 and 80 weeks after conventional treatment stops. For the right patient (typically over 40, sun-damaged skin, pigment beyond melasma alone), I stage a longer program aimed at remission, not repetition:
- Stage 1 — pigment reduction (3–20 weeks; 2–4 sessions): lasers, peels and medical therapy — over 85% successful.
- Stage 2 — scaffolding (3–4 sessions): biostimulator injectables preparing the dermis for new collagen.
- Stage 3 — dermal remodelling (3–6 sessions, 4–12 weeks apart): RF microneedling, fractional non-ablative lasers, HIFU — rebuilding the aged dermis that keeps reactivating pigment.
- Stage 4 — consolidation: prescription retinoids (introduced late — they irritate, and irritation can flare melasma), pigment inhibitors and antioxidants to hold the result.
Results build from 4–6 months, peak at 14–24 months, and the full program spans roughly 18–24 months. Success rates run 75–85%, with remission lasting anywhere from a year to 10+ years depending on sun behaviour, genetics and maintenance. The supporting evidence is sobering in the other direction too: in a 2024 trial, patients who stopped treatment without maintenance remodelling regressed back to baseline within 6 months.
