The cause of dark circles under the eye can be lack of sleep. Other known causes is heredity, or a poor diet. To avoid the dark circles, drink plenty of water and get some rest.
Rubbing the eyes too much can cause circles under the eyes as can not getting enough sleep. Aging can also cause circles under the eyes.
According to what I have read, the causes of dark circles under eyes, begin in the capillaries, the tiny blood vessels that web the delicate skin around the eyes. Or in short caused by leaky capillaries.
Lack of sleep, blood vessels under your eyes can become dilated and cause black circles also.
Malnutrition, lack of sleep, and too much contact with rays from the laptop/TV.
