Melasma is a common skin problem. It typically affects women of 20-50 years of age, causing brownish to blue-grey patches on the face. Most people get it on the forehead, bridge of the nose, chin and above the upper lip. It is uncommon in men.
Why do I get it?
The exact cause is unknown. It is due to increased number of melanocytes and melanin, therefore the colour.
Sun exposure is a well known risk factor. Ultraviolet (UV) light from the sun stimulates melanocytes.
