As we age, the skin and muscles of the eyelids stretch and fat redistributes, which can cause the eyes to droop and give the face a tired appearance. Upper eyelid surgery is a procedure that removes excess skin from the upper eyelids and is considered when sagging skin obstructs vision or makes the eyes feel heavy. Lower eyelid surgery addresses bulging fat and sagging skin in the lower eyelids to reduce under-eye sagging and dark circles. The approach may vary depending on whether the drooping eyelids are caused by a simple skin issue, are accompanied by ptosis (weakness of the muscles that open the eyes), or are caused by sagging eyebrows or forehead; therefore, identifying the underlying cause is crucial. For upper eyelid surgery, stitches are typically removed after about a week, and swelling and bruising are common. Since the aging process continues even after surgery, the results may not be permanent, and there is significant individual variation in recovery and maintenance periods.
