Double eyelid means that the skin of the upper eyelid has a shallow groove above the eyelid margin. When you open your eyes, the skin under this groove moves upward, while the skin above this groove hangs loosely at the double eyelid groove and folds down. To form a pair of beautiful double eyelids, we must comprehensively consider the shape and width of double eyelids, the swelling degree of upper eyelids, the width of eyelid cleft, the radian of eyelid margin, the ratio of eye height to eye width, the distance between eyebrows and eyes and other factors.
