A 2017 study found that spending an hour pounding the pavement could translate to an added seven hours to your life. Other research has shown that regular running makes you happier (see our fitness director Jen Ator’s Insta for more on how we feel about that). And of course, it’s a great cardio workout.

But when it comes to your skin, there are some interesting concerns that runners don’t always think about. So we caught up with dermatologist Robert Anolik, M.D., and Goesel Anson, M.D., plastic surgeon and founder of skin-care brand FIXMD, to talk more about the skin concerns specific to runners.
