Cosmelan is a professional depigmentation system designed to address melasma and uneven skin tone. The treatment involves a two-phase process: a medical-grade mask applied in-clinic that works to inhibit melanin production, followed by a take-home maintenance cream used over several weeks. The procedure targets the overproduction of melanin responsible for dark patches and discoloration.

Cosmelan works best for individuals with melasma, post-inflammatory hyperpigmentation, or generalized uneven skin tone. It is suitable for most skin types, though those with sensitive skin or active inflammation may need to wait until their skin stabilizes. A qualified provider can assess your specific condition and determine if this treatment aligns with your goals.

The in-clinic session typically lasts 30 to 45 minutes. Your provider will cleanse your skin and apply the Cosmelan mask evenly across the treatment area. You will leave the mask on for a specified duration before removal at home, following precise instructions. The process is non-invasive and generally painless, though mild tingling or warmth may occur.

You can resume normal activities immediately after the mask application. During the following days and weeks, your skin will begin to peel as the depigmentation process unfolds. Strict sun protection is essential during treatment and maintenance phases, as sun exposure can compromise results and trigger melasma recurrence.

Visible lightening of dark patches typically begins within the first week and continues to improve over 2 to 3 months of maintenance. Results vary depending on the depth and extent of pigmentation and individual skin response. Maintenance is often necessary to sustain improvements, as melasma can recur without ongoing prevention.
