Selenium sulfide
"I developed tinea veriscolor during a particularly hot summer about 3 years ago.  I've been to 5 different doctors and been prescribed every pill and lotion imaginable. None of them worked! I was embarrassed to go out, I felt like everyone could see it and I was so frustrated that nothing helped. THEN, I was in urgent care for an unrelated condition and the Dr took a look at my neck while checking my ears and told me to use Selsun (selenium sulfide 1%) as a lotion.  I started using it at night a few days ago and my skin is redder, patchier and tender but I can SEE THAT IT IS WORKING! Moisturizing lotion is a necessity during the day with this treatment!"
