Melasma: Is a stubborn pigmentation seen mainly in women. Occasionally, men too get affected by this condition. It is characterized by a patchy tan or brown discoloration that occurs over the upper lip, cheeks, forehead, chin and bridge of the nose. The areas affected are bilateral and frequently symmetrical.
