With advancing years the thin membrane that holds back this fat weakens, and the fat can protrude, producing bulges or bags in both the lower and upper eyelids. Bulges caused by protruding fat, especially in the lower eyelids, can be a hereditary problem even in younger persons. Lower eyelid surgery can improve these fatty bulges on someone who does not yet require tightening of the lower eyelid skin. Thus, during eyelid surgery, excess skin and protruding fat of the upper and lower eyelids are removed. These changes that you see around your eyelids are hereditary.
Different people acquire the changes at different ages, depending on how their parents' eyes aged.
Men can benefit in the same way from the same surgical techniques. This operation is usually performed on people in their forties and fifties, when the signs of aging are evident enough that the benefit obtained is a fair trade for the cost and risks of surgery. There is no upper age limit for having eyelid surgery. On the other hand, hereditary fat protrusions, especially in the lower eyelids, can occasionally make someone as young as twenty a good candidate for eyelid surgery. As gravity pulls on the facial skin over the years, loose excess skin becomes present in the forehead region, and the eyebrows drop in position.
