Blepharoplasty, also known as eyelid lift, is a cosmetic eyelid surgery used to refresh your appearance by removing the extra skin of the eyelids. As you age, your skin stretches and the muscles holding your eyelid skin weaken. Because the eyelid skin is so thin, it is common for the eyelid skin to droop and for wrinkles and bags around the eyes to develop.
