Several factors such as aging, sun damage, smoking and obesity can cause the eyelids to droop and sag as the supporting tissues deteriorate. This area is often one of the first to deteriorate, as the skin of the eyelid is thinner than the rest of the face. Eyelids that droop or bulge can cause people to appear much older or fatigued than they actually are. Blepharoplasty or eyelid surgery is a surgical procedure that improves the appearance of the upper and lower eyelids by tightening muscles and tissue or removing excess fat and skin. This procedure can be performed on men and women alike and offers a younger more refreshed look that reflects across the whole face.
