Dark circle

Black or dark circles under or around the eyes can be caused by many different factors. The following are the most common causes of those unattractive dark circles.

Like varicose veins, dark circles under the eyes are usually an inherited trait. If you have dark circles, there is a good chance that others in your family also have them.

The more transparent your skin, also an inherited trait, the darker the circles appear.

Deep set eyes may have a tendency to develop dark shadows under them. In fair-skinned persons, dark eyes become more obvious.

Increased exposure to the sun can draw pigmentation the skin’s surface and create dark circles.

Any condition that you have that causes your eyes to itch can contribute to darker circles under the eyes because rubbing or scratching the skin can darken the skin. Hay fever sufferers particularly 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.

Any medications that you are taking that causes blood vessels to dilate, can cause circles under the eyes to darken. Because the skin under the eyes is very delicate, any increase blood flow shows through the skin.

A lack of sleep or excessive tiredness can cause paleness of the skin, which again allows the blood underneath the skin to become more visible and appear more blue or darker.

If you have a propensity to have dark circles under you eyes, as you grow older, they are likely to become more noticeable and permanent. Excess folds of skin under the eyes will also make dark circles more pronounced.
