Is there anything I can do reduce the dark circles around the eyes?

Several skin care lines carry products which focus on lightening dark circles around the eyes.  The process incorporates increasing the micro circulation of the skin under the eye, as well as exfoliating and lightening the skin.  Some dark circles are visible due to the shape of the eye socket, which casts a shadow.  Other causes can be an accumulation of fat beneath the lower eyelid, which also casts a shadow.  In that case, surgery would be an option to decrease the appearance of dark circles.  Technology has improved greatly in this area, whereas previously there was nothing that could be done to decrease dark circles.  Depending on the cause of the dark circles, the newer products have shown tremendous improvement for patients dealing with that problem.
