With advancing age, orbicularis oculi muscle and eye skin gradually lose elasticity, coupled with the weakening orbital fascia no longer able to well enclose the fat behinds it. As a result, the orbit fat bulges and pushes through the less reinforced septum, leading to the formation of eye bags. In addition to the impact of aging and gravity, staying up late at night and puffy face will make the eye bags look more prominent.
The conjunctiva lines the inside of eyelids. Underneath the conjunctiva lies the orbital fat enclosed by the orbital fascia (orbital septum). Exterior to the orbital fascia are orbicularis oculi muscles and skin. The tear trough ligaments originated from the orbital rim run through the orbicularis oculi muscles and skin and attach them to the orbital rim. The skin above the orbital rim is very thin and has no subcutaneous fat. The orbital fat is held in place by the orbital fascia right under the eyes. eyebag surgery taiwan Eye bags are mostly formed due to aging when the loosing orbital fascia (orbital septum) no longer able to hold the fat in place so the fat bulges forward. It has nothing to do with fat overgrowth. There are two ligaments (namely tear trough ligaments) lying along the tear trough groove and attaching the under-eye skin to the orbital rim. With the process of aging, the orbit undergoes continuous remodeling with resorption of the bone along orbit rim. As a result, the tear trough ligaments that attach the skin tightly to the orbital rim will pull the skin inward, resulting in deeper tear troughs.
