What causes the dark circles under my eyes?
under the eyes have several possible causes.
many people, the skin of the lower eyelids is very thin, and the dark that
you see is the venous blood in the veins underneath that thin skin. No good treatment is available for that condition, because we don't know
how to coax the veins to carry less blood.
the dark circles are actually excess pigment in the skin of the lower
eyelids, as if the skin had a huge freckle that covered much of the lower
eyelid skin. You can tell if that's what is going on by stretching
the lower eyelid skin down and to the side, and carefully comparing the
color of the skin to the color of the adjacent cheek skin. When
pigment is the problem, it can often be treated with topical bleaching
creams (not hugely effective) or with a skin peel, which tends to pull
excess pigment out of the skin.
dark circles can just be shadow. With time, the lower eyelids
usually develop little bulges, which represent the fat that cushions the eyeball
pushing forward. The fat bulge makes it look as though there were a
little groove underneath the bulge of fat, and that semi-circular groove looks
like a dark circle. Fat bulges can be treated with lower eyelid
surgery, also called a lower eyelid blepharoplasty.
