The primary advantage of blepharoplasty is the improvement in facial aesthetics. By removing excess skin and fat from the upper and lower eyelids, this surgery can create a more youthful and refreshed appearance. It can also help reduce puffiness and dark circles around the eyes, making the face look more vibrant. Additionally, blepharoplasty can address functional issues such as sagging eyelids that obstruct vision, providing both cosmetic and medical benefits.
