By removing excess fat, skin and muscle from the upper and lower eyelids, blepharoplasty can rejuvenate puffy, sagging or tired-looking eyes, giving a more youthful appearance. The procedure is also done to remove puffy bags under the eyes. It is typically a cosmetic procedure but can also improve vision by lifting droopy eyelids out of the patient's field of vision. Because blepharoplasty cannot be used to raise the eyebrows or reduce the appearance of wrinkles, crow's feet or dark circles under the eyes, the procedure is often combined with others such as a facelift and BOTOX treatments.
