 [ Symptoms ] hello i play football and i always end up with a rash on my chin and forehead anything i can do  it first starts out red and patchy but then turns brownish greyish it then peels about every two weeks i have used slip on covers for my chisntrap and the results do not change sun exposure also makes it much much darker any ideas on medications or what i have someone said it might be a heat rash and there is nothing i can do about it any ideas [ Disease ] i used to play football and suffered from this as well i personally put a little bit of vaseline on my chin and forehead before putting on my helmet it helped also if that doesnt work try putting a fungicide on your chin guard and the inside of your helmet it could be a form of jock itch you get sweaty in those helmets and they can be a breeding ground for all sorts of things hope this helps
