Dermatologists measured improvements in the appearance of the faces of a small group of middle-age women after they did half an hour of daily face-toning exercises for eight weeks, followed by alternate-day exercises for another 12 weeks.

Dermatologists looking at unmarked before-and-after photos saw improvements in upper cheek and lower cheek fullness, and they estimated the average age of women who stuck with the program as significantly younger at the end than at the start. The average estimated age dropped almost three years, from nearly 51 years to 48 years.

Participants also rated themselves as more satisfied with the appearance of their faces at the study’s end, Alam and colleagues reported in JAMA Dermatology.
