The most important thing is that this place even if you do laser or frozen, pay attention to ventilation, dry to keep clean, try to avoid picking with your hands, try to avoid rubbing when bathing, because the warts are caused by human papillomavirus infection, if rubbing or picking with your hands, it is easy to infect other places on the body to grow warts.
