How does selenium sulfide treat tinea versicolor?

Selenium sulfide can be used to treat tinea versicolor (or pityriasis versicolor), a fungal skin infection that causes small patches of skin to become scaly and discolored. Tinea versicolor is caused by an overgrowth of a yeast-like fungus that grows in the oil (sebum) found on the skin. Selenium sulfide can destroy those fungus cells and reduce the symptoms of this condition. Talk to your doctor if you have questions about treating tinea versicolor with selenium sulfide.
