Is this Clotrimazole 1% w/w Dusting Powder helpful for tinea versicolor?

Clotrimazole is an antifungal that does work against the yeast responsible for tinea versicolor, and a dusting powder can be especially useful for larger areas like the back or chest, since it keeps the skin dry as well as treating the infection. It usually needs a few weeks of consistent use, and the pale patches can take even longer to blend back with your normal skin tone after the fungus clears. If you don't see improvement in a couple of weeks, it's best to see a doctor to confirm the diagnosis and see if a different formulation suits you better.
