in some cases, dark circles are hereditary and there's nothing you can do about it.

the skin under the eyes is VERY thin and veins are close to the surface, hence the bluish cast.

creams with vitamin K are supposed to strengthen blood vessels and make them less noticeable. as Scarlet pointed out, reduced salt intake and elevating the head of your bed helps too.

use a yellow or orange-toned concealer to hide circles. my favourite for this purpose is from the stage makeup company Ben Nye. i like their "tattoo cover" in light orange.

don't put sunscreen too close to your eyes. wear BIG dark glasses whenever you're out in the sun! i have a pair that wouldn't have looked out of place on Jacqueline Kennedy Onassis!!!
