An eyelid lift (eye surgery), technically known as blepharoplasty, focuses on the human eyes. The eyes occupy an extremely prominent part of the facial features that a person has. It is however the surrounding skin of the eyes, rather than the eyes themselves, that convey emotion. The muscle, fat, tissue, hair, and lashes all contribute to a very wide array of expressions. Sun exposure, heredity, and age are all factors that contribute to deep fine lines, wrinkles, and puffiness around the eyes.
