Cosmelan is a depigmenting treatment used to reduce the appearance of hyperpigmentation, such as melasma, sunspots, and age spots. It is a topical treatment that is applied to the affected areas of the skin.
Cosmelan is a prescription treatment, so you will need to see a doctor or dermatologist to get a prescription. Once you have a prescription, you can purchase Cosmelan from a pharmacy or online retailer.
