1 . Patients often come into my office and ask, “How can I look younger?” While I always suggest healthy living — a balanced diet and regular exercise — in order to look and feel younger, I have never thought of facial exercises as part of that plan. That is, until a recent study, published in JAMA Dermatology (皮肤学), showed promising results that routine facial exercise may slow the merciless tide of time.
The theory behind the study originates from the fact that a major part of facial aging is due to the loss of fat and soft tissue, which leads to the growth and spread of wrinkles. If we can lift weights at the gym and enlarge muscles in arms, why couldn’t the same be done for muscles in our faces, therefore to create a more youthful face?
The concept of facial exercise is not a new one. A simple Internet search will produce a lot of blog posts and books on the subject, as well as various programmes that promise to be the next fountain of youth. What the JAMA Dermatology researchers did in their study, which was the first of its kind, was to examine this question from a more strict scientific aspect. They enrolled 27 women between the ages of 40 and 65 to perform daily, 30-minute exercises for eight weeks, and then continue every other day for a total of 20 weeks.
Dermatologists who did not know the participants were asked to rate their photographs before and after the exercise. The dermatologists found an improvement in cheek fullness and estimated the age of the participants at 51 years of age at the start of the programme and 48 at the end of the 20-week study. Furthermore, all the participants felt improvement in their own facial appearance at the end of the study.
While these results seem exalting, the study has some obvious limitations. Of the 27 patients involved, 11 gave up before completing the study. One reason may be that the programme was to time-consuming, clocking in at 30 minutes a day. The overall small size of the study also limits its generalizability to the larger population. In addition, there was also no control group, which would have helped reduce the possibility that this improvement happened by chance.
It’s also hard to draw conclusions about the longevity of these results. Probably the exercises must be continued to keep their effects. But for how long? And how frequently? Which exercises are most effective? Most studies are need to answer these questions.
