9 Things Women with Great Skin Do Before and After a Workout
If you're exercising outside while the sun is up, you obviously need sun protection. But if you work out in a sun-drenched gym or your favorite piece of equipment happens to be the one next to the window, you need SPF too. UVB rays, the main cause of sunburn, can't penetrate glass, but at least 50 percent of UVA rays, which contribute to significant sun damage and skin cancer, can. Pick a broad-spectrum water-resistant or sweat-proof formula and apply it 15 minutes before you start working out so your skin has time to absorb it.
