(greater than 8 mm), medium (6 to 8 mm) and narrow (5 to 6 mm). The medial aspect of the heavy eyelid line starts at the inner corner of the eye or 1 to 2 mm above the inner corner of the eye and is usually highest at the junction of the inner 1/3 and middle 1/3 of the upper eyelid, while the lateral aspect is vertically above the outer corner of the eye and is 1 to 2 mm smaller than or equal to the middle height. The length of the eyelid line The eyelid line starts from the inner canthus and extends beyond the outer canthus by 3 to 5 mm. In older adults, the eyelid line can be extended outward to remove loose upper lid skin and eliminate crow’s feet, usually by 5 to 10 mm, but the longest should not exceed the vertical line at the end of the eyebrow.
