Darkness around the eyes is commonly seen in dark circles. Dark circles are common in physiological as well as pathological states. For physiological states, they are mostly caused by staying up late, mood swings, eye fatigue, aging, etc., when the blood flow under the skin of the eyes is too slow, forming stagnation and leading to the dark phenomenon. In addition, for pathological diseases, such as insufficient oxygen supply to the tissues and excessive accumulation of metabolic waste in the blood vessels, can also lead to pigmentation of the eyes, resulting in dark circles. In older people, the subcutaneous fat around the eyes becomes thin and the dark circles become more pronounced at this time. For dark circles around the eyes, attention should be paid to avoid straining and to exclude organic diseases. It is recommended that blood tests be performed to clarify whether there is anemia, and systematic tests can also be performed to clarify whether there is organic heart disease or respiratory disease, resulting in insufficient oxygen supply to the tissues.
