Dark Circles #2

Under eye dark circles or Peri orbital Melanosis in Dermatology Terms, is a difficult to treat condition. There are many causes for it. Marked periorbital melanosis is seen as a genetic trait. Pigmentation of the periorbital skin can also be post-traumatic, post-inflammatory or can accompany hormonal changes. Chemical pigmentation can occur from prolonged use of a mercurial or silver preparation, producing a slate-blue or greybrown discoloration. Local increase in pigmentation may also be due

to cosmetics containing phototoxic agents, usually psoralens. Increased pigmentation can also follow inflammatory dermatoses such as eczema and lichen planus. Even Acanthosis nigricans is now a days implicated in causing pigmentation around the eyes.
