The amount of skin that rests below the eyelid crease. The fold is the redundant skin that folds over the crease. No everyone has an eyelid fold; some people may not have a fold if they have a high lid crease and no redundant skin. Others may have a low eyelid fold with some of the excess skin touching the lashes. Blepharoplasty surgery can change the eyelid fold depending on the desires of the patient.
