Home / Melasma
It is a common acquired pigmentary disorder where light to dark brown patches occur on face in a symmetrical distribution. It can also occur on the neck and forearms. It affects sun exposed areas and is commonly seen in women of child bearing age. It affects women more than men. The prevalence of melasma in women varies from 1.5% to 33% depending upon the geographical location and population studied. A study suggested that prevalence in men is 20%.
The exact cause of melasma is not known but multiple factors such as sun exposure, hormone replacement therapy, contraceptive pills and thyroid dysfunction have been implicated. There is a genetic predisposition to develop melasma. Family history is positive in around 30% of cases.
There are various topical medications available for melasma but the most important is sun protection. The more you protect yourself from sun rays, the faster the lesions will get better and stay so for a longer time.
