Dark circles form when blood drains from the upper eye into the thin opaque skin of the Tear Trough area, just under the lower eyelid. Because the vessels that run along this trough are very narrow, "blood pooling" may occur causing dark circles to appear. This advanced eye cream formula firms and tightens the skin around the eyes and reduces fine lines and wrinkles. It also designed to increases the diameter of these vessels and speeds the flow of the pooled blood through the tear trough and away from the area. The addition of Kojic acids allows a lightening effect to happen in the pigment in the skin around the eyes, thus making the darkened area look much brighter.
