People's eyes are covered by upper and lower eyelids. The eyelid consists of skin, subcutaneous tissue, muscle, meibomian and conjunctiva. With the increase of age, the skin, orbicularis oculi muscle relaxation and fat protrusion will appear in the lower eyelid, and bags under the lower eyelid often form. The causes of pouch formation are mostly congenital factors, while acquired factors such as age, fatigue, insomnia, drinking water at night, inflammation around the eyes, edema and crying will only aggravate pouch. Generally speaking, eyelid skin and muscle relaxation, orbital septum fat swelling and meibomian relaxation are often caused by age factors, but orbicularis oculi muscle hypertrophy and orbital septum fat swelling can be caused by congenital factors. Congenital factors lead to the early age of pouch plastic surgery, about 20 years old, and age-related factors lead to relaxation deformity, generally after 25-30 years old. The formation of bags under the eyes is the manifestation of skin aging. It shows that people are beginning to enter middle-aged and elderly people. The different age of bags under the eyes is related to many factors such as everyone's living environment, habits, nutrition, rest, occupation, heredity and so on. Once the bags under the eyes are formed, the traditional solution is surgery. With the development of science and technology, a non-surgical method of removing bags under eyes has emerged, mainly ultrasonic method, which can effectively eliminate bags under eyes. Other auxiliary treatments, such as skin care and facial massage, can only slow down the aggravation of bags under the eyes, but have little effect on eliminating bags under the eyes.
