Bags under the eyes, also known as blepharoplasty, mostly occur in the lower eyelid. They are due to the relaxation of eyelid skin or hypertrophy of orbicularis oculi muscle, and the accumulation of fat globules in orbital septum, forming local drooping uplift of eyelid, often accompanied by drooping performance. More common in middle-aged and elderly people, both men and women can appear, which is one of the facial signs of aging. A small number of young people will also have bags under their eyes due to genetic or long-term bad work and rest, bad use of cosmetics and other factors. Bags under the eyes are generally caused by structural problems such as skin, orbicularis oculi muscle, orbital septum and orbital septum fat. Only non-surgical methods can only delay the progress of bags under the eyes, and the worse the effect, only through minimally invasive plastic surgery can the problem be fundamentally solved. By removing some slack skin, orbicularis oculi muscle and orbital septum fat and adjusting slack structures such as orbital septum, the eyelid structure can be restored to its young state. Bags under the eyes usually do not have adverse effects on the body, but only show abnormal eye appearance, but may make the face look old and sunken, affecting the appearance and beauty. The skin of the lower eyelid is swollen, swollen and drooping, which may be accompanied by skin relaxation. Sometimes, due to the serious drooping of bags under the eyes, it may lead to tears displacement, lower eyelid ectropion, tears overflow and other manifestations, and it is also easy to cause eye inflammation and foreign body sensation. Some patients may also have symptoms of dark circles. Bags under the eyes refer to the swelling of the lower eyelid tissue and drooping like a bag. Generally speaking, it means that the patient's lower eyelid forms a pocket-like structure. Specifically, it is mainly due to excessive fat accumulation in the orbit. Under the action of gravity, it gradually breaks through the limitation of the lower eyelid, highlights the orbit, and finally forms bags under the eyes. The people with high incidence of pouch are middle-aged and elderly people aged 40 ~ 50, and the proportion of women is higher than that of men.

If middle-aged and elderly people want to remove bags under their eyes, they need to remove excess lower eyelid skin in addition to excess fat, so they can choose external use. By removing the skin, the lower eyelid becomes flat, which takes a long time to recover.
