Dark circles simply refer to those shadows under your eyes that are caused by many factors. Next to lack of rest, the most common cause of dark circles is aging. There is a natural fat pad under the eye that begins to lose shape as you age. This process causes shadows under the eyes. Sometimes, these dark circles are just a reflection caused by the blood vessels and capillaries which are present in large numbers in the area under your eyes.
Often, the shape of your face and features seem to make these dark circles appear prominent. For example, if you have prominent or protruding cheek bones combined with eyes that are set deep, the dark circles under your eyes are more visible. Some people might have allergies, sinus problems, and more seriously leaking capillaries which are caused by the former. The medical reasons for dark circles under your eyes are poor diet, lack of enough sleep, poor or irregular blood circulation.
