Those long unexpected Summer runs sounded so fun . . . until you start feeling that familiar pesky rash that comes from your thighs rubbing together for long periods of time. Although you're likely to dismiss it as a serious health issue, it can lead to long-term scarring and discoloration. Prevent inner-thigh chafe by equipping a handy bandelette and body balm when you're out and rubbing coconut oil on the affected area to prevent scarring and ease pain.
