Unfortunately, melasma is a condition for which there is no cure. It can be improved with the use of Broad Band Light treatments, hydroquinone and retinoid treatments. Should you decide to manage your melasma with any of these options, sun avoidance and sunscreen are extremely important to minimize further pigmentation.
