What Is Cosmelan and How Does It Treat Pigmentation?
Cosmelan is a professional-grade depigmentation program that reduces excess melanin production to address melasma, sun spots, post-inflammatory hyperpigmentation, and uneven skin tone. The treatment works by inhibiting tyrosinase — the enzyme responsible for melanin production — through a multi-phase program that includes an in-clinic mask application followed by a structured home care routine over several months.
How the Cosmelan Program Works
Cosmelan is not a single treatment — it’s a comprehensive program designed for stubborn pigmentation including melasma. The active ingredients suppress the melanin production pathway at multiple points across an in-clinic and home-care protocol.
The program is used for:
- Melasma (hormonal pigmentation)
- Sun damage and age spots
- Post-inflammatory hyperpigmentation (from acne, injury, or previous treatments)
- Uneven skin tone and discolouration
The 3-Phase Cosmelan Timeline
Phase 1 — Pre-Treatment (Weeks 1–4)
Your skin is prepared with prescribed products that begin regulating melanin activity and strengthening the skin barrier. This phase ensures your skin responds optimally to the mask application and reduces the risk of adverse reactions.
Phase 2 — In-Clinic Mask Application (Day 1)
The Cosmelan mask is applied in the clinic and left on for a prescribed period (typically 8–12 hours, depending on your skin type and the severity of pigmentation). You’ll leave the clinic with the mask on and remove it at home as directed.
In the days following, you’ll experience controlled peeling and redness as the active ingredients work on the pigmented cells. This is expected and a sign the treatment is working.
Phase 3 — Home Care Maintenance (Months 1–6)
This is where the long-term results are built. You’ll follow a specific home care routine using Cosmelan 2 cream and supporting products. Strict adherence to this routine is essential for maintaining results and preventing pigmentation from returning.
What Results Can You Expect?
Results vary depending on:
- The type and depth of pigmentation being treated
- Your skin type and tone
- Sun exposure habits (strict SPF50+ daily protection is essential throughout)
- Hormonal influences (particularly relevant for melasma patients)
- Adherence to the home care routine
Many patients see a gradual reduction in pigmentation across the program, with continued improvement over the full 6-month course. Outcomes vary by individual.
Important Aftercare Requirements
- SPF50+ sunscreen must be applied every day — including on overcast days and when indoors near windows
- Avoid direct sun exposure as much as possible during the program
- Follow the home care routine exactly as prescribed
- Attend all scheduled review appointments
- Do not use any products not approved by your clinician during the program
FAQ — Cosmelan Treatment
How long does the Cosmelan mask stay on?
The mask is typically left on for 8–12 hours depending on your skin type and the severity of your pigmentation. Your clinician will provide exact instructions for removal.
When can I wear makeup after Cosmelan?
Most patients can resume wearing mineral makeup within 5–7 days after the mask application, once the initial peeling phase has settled.
Will my pigmentation come back after Cosmelan?
Cosmelan reduces pigmentation and suppresses future melanin overproduction. However, ongoing maintenance is required — particularly strict sun protection and continued use of prescribed products.
Is Cosmelan safe for darker skin tones?
Cosmelan can be used on all skin types (Fitzpatrick I–VI), but the protocol is adjusted for darker skin tones to minimise the risk of post-inflammatory hyperpigmentation.
