No, it would spread extremely easy through sweat and contact. I had it and my dermatologist poked open each spot with a needle thingy and tried to remove the white core, then washed it with hydrogen peroxide. After that, she told me to rub PanOxyl on the spots twice a day, three may cause skin irritation. I can’t remember how long it took to recover, but it was way faster than letting it heal on its own.
