In medicine, bags under the eyes are also classified into different categories, and different types of bags under the eyes are certainly treated differently, and the causes of bags under the eyes are also different. Generally speaking, the causes of under-eye bags can be divided into two types: congenital and acquired. Congenital under-eye bags, which are caused by genetics, start to appear around the age of 18. Acquired eye bags are also divided into youthful (light), middle-aged (medium) and old (heavy) types. After the age of 30, people are prone to skin laxity and increased orbital fat, while the orbital fascia also starts to relax and the support of eye fat decreases, which is why eye bags appear. In terms of treatment, congenital eye bags and acquired youthful type eye bags are usually simply too much orbital septal fat, without orbicularis oculi muscle and skin laxity, simply remove the fat without removing the lax skin, mostly using small incision minimally invasive conjunctival approach surgery, the surgery can be completed in about 30 minutes, the incision is not visible externally, and you can go to work after a day’s rest. In middle-aged and older people, in addition to excessive orbital fat, the orbital septum fascia, orbicularis oris muscle and skin are also combined, or the orbicularis oris muscle is hypertrophic, and the procedure is mostly performed through a skin incision, during which the excess orbital fat, part of the lower lid skin and the loose orbicularis muscle are removed.
