Riehl's Melanosis

definition

Spotty brownish-grey pigmentation on the face and occasionally on the neck and arms primarily seen in adult women with a history of exposure to cosmetics. Tar derivates and photoreactive substances in cosmetics are suspect. Nutritional and other factors may be involved, as this condition may also appear in men, children, and in individuals with no previous contact to cosmetics.
