Runner’s face generally occurs in both men and women ages 40+ who exercise to improve their body, and in doing so end up with a skeletal and bony face. When exercising, an athlete burns off fat beneath the layers of his/her skin. The marked loss of fatty tissue results in a loss of volume which leads to a prominent appearance of the bones, accelerated development of skin laxity and deepening of wrinkles. Though you may look like a 20-year-old from the neck down—your face will easily give away your age.
“Runner’s Face” can occur in anyone who has a very lean face, including avid bikers (Lance Armstrong), tennis players (Ivan Lendl), and people with eating disorders (the late Karen Carpenter). Maybe “Skinny Face” is a better term for it.
