Eyelid rejuvenation is a surgical procedure that counteracts the effects of aging on the eyes. The procedure can be done on the upper eyelids, the lower eyelids or both. Eyelid skin usually starts to sag in the 40s. These procedures remove excess skin and fat, if present, to tighten the eyes and reduce puffiness. Upper lids can easily be done in the office under local anesthesia. Discomfort and downtime are minimal.
