Why does it need so long to get rid of athlete's foot fungus?

Fungus is everywhere: Usually fungus infections of the skin will take 7-14 days to resolve wtih a good topical antifungal using it appropriately. If you are not consistent it is hard to get rid of it. Once it does clear you have to continue to use a topical on a regular basis to keep it from returning. If you are suseptible to the fungus, it is likely to return without regular treatment. Dr. L.

Thick skin: The skin on the foot is thick and the warm, dark, moist environment is conducive to fungus. Using a topical regularly will normally clear the fungus. Once you stop the medication, the skin can get reinfected. Have the topical handy to start at the first signs of a fungal infection. Dr l.
