Behind the skin and muscles of the lower eyelids, there is a membranous connective tissue that prevents the fat in the lower eye socket from protruding outward. When the eye socket fat is excessively accumulated, or the strength of the film tissue becomes weak, the fat bulges, making the lower eyelid look like a bag, which is called the "under the eye bag." In addition, the spirit of the night is not good, and then the lymphatic circulation speed will slow down, and the "waste" that cannot be discharged smoothly will gradually accumulate. Over time, it will also produce annoying eye bags.

The circulation of capillaries around the eyes is poor, and the nutrient and oxygen supply capacity is weak. If the lack of sleep, excessive fatigue, resulting in poor blood circulation, it will form dark circles. If it is caused by hereditary dark circles, I am afraid it is more difficult to cure.
