you could try apple cidar vinegar n water mixed and put it on it. some mix 50/50 some mix 70 water/30 vinegar but they say to get the one that says mother on it. hibliclenz has yeast properties its a soap though you wet put it on and rinse it off. duoxo pads are good for this and can be ordered online. probiotics can help get rid of it and can be added to the treatment. it kills it inside out. yes any fungal med will work such as athlete foot treatments and jock itch treatments. also need to see whats causing it as its usually allergy related on bullies.
