Anatomy and Aging of the Perioral Region.

Facial Plast Surg 2021 Apr 12;37(2):176-193. Epub 2021 Apr 12.

Medicina Estética, CM Clinic, Palma de Mallorca, Islas Baleares, Spain.

Perioral region, although severely impacted by facial aging, is often overlooked in texts on facial rejuvenation. Sun exposure, bone resorption, dynamic contraction of the sphincteric and nonsphincteric oral musculature, gravitational pull, histological changes of the skin, and unhealthy habits all take their toll in this area. Fine wrinkling on the lips, deep nasolabial and mentolabial folds, elongation and flattening of the upper lip, downturned corners of the mouth, marionette lines, diminished vermillion and upper teeth show and chin irregularities are the main signs of this process, raising great concern amongst patients and making the perioral region the most demanded area for facial rejuvenation treatment.
