Heredity [edit]. In most cases, the dark circles under the eyes are blood vessels that can be seen through the skin. The skin around the eyelids (periorbital skin) is the thinnest skin in the body (around 0.5 mm thick compared with 2mm in other areas). Like varicose veins, dark circles under the eyes are usually an inherited trait.
Any condition that causes the eyes to itch can contribute to darker circles due to rubbing or scratching the skin around them. Hay fever sufferers in particular will notice under-eye smudges during the height of the allergy season. Some food allergies can also cause the area under the eyes to appear darker.
