Puffy eyes are caused by excessive accumulation of intraorbital fat or weakness of the lower lid support structure causing the intraorbital fat to break through the lower lid and protrude outside the orbit. Its formation is partly related to genetics, and partly due to ageing, poor rest, lack of sleep, chronic anxiety, and depression. People who work in front of a computer for a long time will also have more chances of having bags under their eyes. Under-eye bags not only make people look old and tired, but also affect their eyesight in serious cases. There are real and pseudo bags under the eyes. Pseudo eye bags will fade away as the cause of the problem is eliminated. However, true bags under the eyes are difficult to disappear and conceal with any medicine and superb make-up, and they will become more and more obvious with age. True under-eye bags must be treated surgically. Eye bags revision surgery is divided into internal incision and external incision revision surgery, internal incision surgery does not have any incision marks, external incision surgery incision in the lower lid margin under the eyelashes 1 ~ 2 mm, after recovery marks are basically invisible. Classification of eye bags: 1.Simple orbicularis muscle hypertrophy type eye bags, its prominent feature is close to the lower lid margin, arc-shaped continuous distribution, the skin is not loose, can not do surgery. 2.Simple skin laxity type In this case, the skin of lower lid and outer canthus is lax, but there is no orbital septum laxity and orbital fat protrusion, and small wrinkles appear around the eyes, mostly seen in middle-aged people aged 33~45. This type requires external eye bag revision surgery. 3.Mild to moderate bulging of lower lid is mainly caused by congenital overdevelopment of orbital septum fat or poor rest, mostly seen in middle-aged people aged 23~36. This type is feasible for internal incision eyebag revision surgery. 4.Severe bulging of the lower eyelid with orbital fat protrusion and skin laxity of the lower eyelid, mostly seen in middle-aged and old people aged 45~68. This type also needs to perform external eye bag revision surgery.
