Eyelid projection, also known as LASH, is a medical procedure in which a patient's eyelids are surgically altered to create a more aesthetically pleasing appearance. This procedure can involve the removal of excess skin or fat from the upper and/or lower eyelids, as well as the reshaping of the eyelids to create a more open, youthful look. The procedure is often used to correct drooping eyelids, reduce puffiness, and improve vision.
