Due to aging and genetic reasons, the muscles around the eye area loosen up, allowing the eyeballs to fall down and compress the fat in the lower part of the eye, causing the fat to protrude forward, which visually causes the lower eyelid area to bulge out. Under-eye bags are a result of laxity of the lower eyelid skin, subcutaneous tissue, muscles and orbital diaphragm, thin eyelid skin, thin and lax subcutaneous tissue, and fat behind the orbit that protrudes to form a bag-like protrusion called an under-eye bag. This results in under-eye bags. There are many factors that contribute to the formation of under-eye bags, genetics is an important factor, and it becomes more and more obvious as we age. However, if you take good care of your eyes, the bags can be controlled. Also, you should not stay up late at night, as this will also produce bags under the eyes, and you should pay attention to daily hygiene and rest. Under-eye bags are common in middle-aged and elderly people around 40 years old, both men and women can occur, it is one of the early manifestations of human aging. Of course, with the improvement of people’s material and cultural living standards and the development of science, it is possible to delay the occurrence of under-eye bags. Generally speaking, adults, especially women, will have bags under their eyes between 25~30 years old. This is mostly the result of fat accumulation. The age at which annoying bags appear depends on the person, and most of them occur around the age of forty-five. The bags have a great impact on the appearance of the eyes, which not only make people look old, but also cause complications such as lower lid ectropion and lower lid edge inversion by the relaxation of the orbital septum. Scholars suggest that the process of facial aging change is actually the process of increasing facial curves. The aggravation of bags is an important sign of aging changes in the lower eyelid. As the skin of the lower eyelid relaxes with age, the orbital septum becomes less supportive, the orbital septum prolapses, and the tone of the orbicularis oculi muscle decreases, resulting in a pouch-like enlargement above the inferior orbital rim and a deepening of the cheek-lid furrow, forming the so-called eye bags. The aggravation of bags under the eyes is caused by excess fat. This is also a very representative understanding that the orbital fat has its normal physiological function and its main function is to protect the eye. It is also one of the reasons for the formation of bags under the eyes. The “pouch-like” appearance is due entirely to the hypotonicity of the orbital septum. The way to remove these bags is to perform surgical liposuction. If surgical liposuction is performed without repairing the orbital septum, the result will inevitably be a recurrence of under-eye bags. If a large amount of fat is removed, that will inevitably cause depression of the lower lid and aggravate the appearance of aging. The muscles around the eyes loosen and allow the eyeballs to fall downward, compressing the fat in the lower part of the eyes and causing the fat to protrude forward, which is visually seen to bulge out in the lower eyelid area, causing unsightly and prominent capsular bags.
