The Mesoestetic Cosmelan peel is the gold standard for treatment of hyperpigmentation and melasma. During a Cosmelan treatment, a depigmentation mask will be applied to the skin for a specific period of time. The skin will peel for up to one week after treatment. Patients will be instructed to follow a specific skin treatment regimen for 30 days to yield ideal results. Sun protection is crucial during and after Cosmelan for best results and to best diminish the risk of pigmentation recurrence.
