You'll probably be surprised to find out that washing your face before you exercise is what's so very important in trying to prevent acne breakouts from sweating during exercise. Nobody would dispute that exercise is terrific for your body, your heart and your mind. But I think it's controversial as to whether all the sweating that occurs during exercise does anything good at all for your skin. But one thing's for sure; the sweating that occurs is annoying. So what do we do? Of course, we wipe it away and when we wipe it away that motion is fast and it's not gentle. And effectively what it does is grinds any make-up, dirt, debris or oil that's on the skin into the pores. And in doing that, you promote clogs and acne breakouts. So how do you prevent that? The best way to do that is to make sure that before you exercise, take off your make-up and wash your face thoroughly and then tone it thoroughly to make sure that you removed all of the make-up, all of the oil, dirt, debris so that when you do wipe your perspiration away you won't clog your pores or cause acne breakouts.
