Background:Melasma is a common hyperpigmentation disorder characterised by symmetrical, marginated, light to dark brown patches that occur mostly in sun exposed areas of skin, mostly on the face, occasionally affecting the neck and forearms. The exact cause of melasma is unknown, however many factors have been implicated in its etiopathogenesis, mainly sunlight, genetic predisposition, pregnancy and certain drugs. Among the factors mentioned above, excessive sun exposure is the most common cause.
