Predisposing factors for panda eyes
Dark circles are a common problem that can make people look tired and have no spirit. Many people want to go and then go quickly. Why is there a dark circle? According to the report of Dr. Launn of France in 1992 The causes of dark circles include the following:
(1) Congenital or acquired eye pigmentation: the congenital eyelid muscle of the patient is more congenital, or the pigment of the eye skin. The congenital constitution is darker and darker than the skin pigment of the adjacent part, so it appears Dark gray eyes.
(2) The eyelids are aging and slack, and the skin wrinkles together to cause the appearance of the skin to deepen.
(3) Eye bags appear to cause shadows.
(4) The lower side of the eyelid is sunken to form a naso-jugal groove to form a shadow.
(5) The retention of blood flow in the eyelid veins causes the skin to darken.
(6) Pigment particle penetration of cosmetics: Commonly used cosmetics, there may be some dark cosmetic particles that penetrate into the eyelids. For a long time, it will show dark circles.

Dark circles are actually divided into two colors, one is cyan dark circles, this is because the venous blood of the microvessels is retained; the other is brown dark circles, which are caused by melanin production and metabolism, and the causes of the two dark circles are completely different. . The black-black eye circles usually occur in the age of 20, and people with irregular working schedules are particularly difficult to avoid because of the slow blood flow in the microvessels, the increase in blood volume and the increase in oxygen consumption, and the result of a large increase in hypoxic hemoglobin. The skin appears dark blue. Because there are many microvessels around the eyes, factors such as lack of sleep, eye fatigue, stress, anemia, etc., can cause congestion and edema around the eyes. The cause of tea black circles is closely related to the increase of age. Long-term sun exposure causes pigmentation in the eye area. Over time, it will form lingering dark circles. In addition, the melanin metabolism caused by blood retention is slow, and the skin is too dry. It will lead to the formation of brown dark circles.
Diagnosis
Differential diagnosis
The eyes are black, usually in three cases:
The first is that the skin of the upper and lower eyelids near the eyelashes is brown or light grayish black, sometimes accompanied by mild roughening or wrinkling of the skin. This type is rare, and it only appears after middle age. The causes of this type of eye circles are more complicated, and some are more likely to leave more prominent pigmentation spots after trauma. Some have seborrheic dermatitis, black lesions, and upper eyelid nerves in the skin of the eyelids. After dermatitis, dermatomyositis or severe blepharitis, different degrees of rough skin, thickening and pigmentation can be formed.
The second type is a tan or light gray black-curved strip with a 45-degree angle from the inner corner of the eye. When it is young, it is not obvious. When it reaches the middle and old age, it starts to go outside and reaches the outer corner of the eye. It is a complete semicircle. , about a few millimeters. This type is more common, almost all of the youth to the old age, only the difference in color and shade. This type of eye circles is black, usually formed with changes in age and physical health, mostly due to severe insomnia, anemia or certain women's diseases, such as irregular menstruation, functional uterine bleeding and sexual intemperance, etc. The color will be aggravated and obvious.
The third is the reflection of certain pathological changes on the periocular capillaries. Such as arteriosclerosis, menopause, poor physical condition, will cause congestion around the eyes, and then blood stasis, will also make the eyes black.
In short, most healthy people can have different degrees of black circles, not morbid, usually pay attention to adequate sleep and proper nutrition, eat more fruits, vegetables and foods rich in vitamin C, if necessary Some eye massage, warm compresses, etc. The motherland medicine believes that people's "blood and blood" ups and downs and changes in viscera often reflect on the face. Therefore, if the change is more obvious and the duration is longer, you should promptly check with your doctor.
