i had tinea (yeast rash) on my skin and this is the only thing that worked.
you may want to swab the area with "clean and clear" or something like that which has sal. acid which topically kills the yeast.gold bond powder also helps/
also get some of those scrubby gloves to use with your neem soap. its better than a washcloth at removing excess skin and oil.
i get my neem soap here:
