Why Is My Skin So Red & Flushed After Working Out? Derms Explain

Workouts can do wonders for the skin. The sweat can clear pores ("Sweat is the best cleanser," board-certified dermatologist Ellen Marmur, M.D., once quipped to us). Moving your body can improve circulation, thereby delivering more nutrients to the skin cells. And being in touch with your body can improve your mental well-being, which in turn can do wonders for skin health.

All around great, no? Unfortunately, there are some common skin complaints post-workout. Occasionally, individuals will complain of increased acne (which is actually the result of not washing your face, gear, or clothing correctly). Or if the increased workouts result in significant weight loss it may cause slight skin sagging. And for some: flushing. 

Often we speak of the post-workout glow (it's real!), but not everyone gets that dewy vibrancy. Some, especially those with light to medium skin tones, appear red—really red. 

Sure, flushing post-workout may be an annoying side effect of a hard-core workout for some, but the reason behind it is pretty cool. Allow board-certified dermatologist Hadley King, M.D., to explain. 

"When you exercise, your body temperature increases. One of the homeostasis mechanisms used by the body when body temperature increases to maintain a healthy body temperature is to carry more blood to the surface of the skin so that heat loss from the skin increases," she says. “This entails peripheral vasodilation—or widening of the small blood vessels found in the skin so that more blood is carried through them. This can cause a red, flushed face, particularly noticeable in fairer skin types." 

Essentially: Working out causes improved circulation no matter who you are—a good thing that has a laundry list of benefits for the skin and body—but for those with skin that's more transparent or even thin, the color comes through more visibly. 

In short: no, and you really don't want to. "There's no 'cure' for this because it's a normal body mechanism," says King. Remember, circulation to the skin boasts a major net gain—so even if the redness isn't ideal in the short term, in the long term you'll be happy.

If it really bothers you, however, "you may be able to minimize it by exercising in a cooler environment and wearing breathable fabrics," she says. 

But just because it may be inevitable for some, that doesn't mean you can't have a few tricks handy to calm the skin down following your sweat session: 

Redness post-workout is totally normal and may be especially prevalent in those who have light or thin skin. There's really no way to prevent it (not that you would want to, as it's good for skin overall), but there are plenty of quick, easy fixes to give a go post-sweat.
