Thanks for the input Mike.
PJ, if you want to tell oif you still have the fungus on your skin, the yeast colony on your skin will flouresce (glow) yellow under UV light (like from a tanning bed).
About 3/4 of the infections clear up from topical treatments. If it proves more stubborn, you may have to go to the doc and get an oral antifungal. Topicals vary on how fast they work.
All of the above info is readily available on the internet. Google "treating tinea versicolor" to learn more.
