The physical activity is probably contributing because of loss of moisture to the skin from sweating and more frequent showers. There are a number of natural products available that both stop the breakouts and prevent future ones. I don't think that you will have to stop playing football....it is good for your health and you obviously enjoy it. You may want to give some natural products a try. There are a few companies that have great products with money-back guarantees if the products don't help. If you email me, I can send you more info on the companies and what is out there. Good Luck!
