I started occasional running/jogging about 7 years ago, progressed to running 6 days a week and then stepped it up a bit this year to more intense (but still under 1 hour), daily runs but still consider myself a beginner.
I've been enjoying regular hill repeats and speed work and running daily for 20-60 mins for about a year and been feeling a lot more healthy (I suffer from depression, severe OCD and BDD). However I just read about 'Runner's face' the other day and I'm quite concerned about it!!
As a BDD sufferer I am very concerned about the undereye bags and lines developing (I'm 27) on my face (to the extent that I avoid having my photo taken altogether, avoid meeting friends and spend a long time trying to conceal my facial features).
According to some sources 'Runner's face' occurs when the retaining ligaments of the face are stretched beyond repair due to constant motion of running, while others suggest it is caused by 'Oxidative Stress', which supposedly occurs during more intense exercise/when exercising at higher heart rates. As I run on hills every day and sprint my heart rate frequently rises to 205 (max: 214) and everyday it rises above 195. Am I damaging my (already fairly ugly) face by running?!
I think this one is going to be difficult to answer, because your BDD will probably influence how you interpret answers given. However I've had a quick read of the research and from a scientific viewpoint it appears to be garbage. Ignore it.
