The labial ledge.
With aging, orbicularis contractions stretch and elongate the upper-lip area, contributing to an aged appearance. The author describes the ideal height of the labial ledge (mustache area) as shorter or equal to the area from the lower-eyelid margin to the supratarsal crease. He explains his technique of shortening the labial ledge and augmenting the philtral columns and upper and lower lips. (Aesthetic Surg J 2002;22:177-180.).
