Why do we sometimes have dark circles under our eyes?

Hundreds of tiny blood vessels in skin below eyes help drain blood from the head. These vessels dilate when ill or tired. Blood concentrates in the vessels and causes them to swell. Skin under eyes is very thin so engorged vessels become visible. Dark circles are actually pools of blood.

Definition: A bluish, grayish or brownish cast under the eyes.

Causes: Extra-thin under-eye skin, hyperpigmentation (the presence of larger than usual amounts of melanin), fatigue, bad circulation, a cold or other ailment.

Rx: After using an eye cream and before applying foundation, dot the under-eye area with a color-correcting underbase. Pale yellow hides bluish or grayish circles and light blue or mauve covers up brownish bags.
