How can doctors tell if I have tinea versicolor?
Doctors can tell by looking at the patches. To know for sure, they may use an ultraviolet (UV) light to look at your skin. Tinea glows under UV light and other rashes don't. Doctors sometimes take small scrapings from your skin to look at under a microscope.
How do doctors treat tinea versicolor?
Doctors may treat tinea versicolor with:
Antifungal cream to put on your patches
Special shampoo, if you have patches on your scalp
Medicine by mouth, if you have patches all over your body or get tinea versicolor often
Your skin may not go back to its normal color for months or years after treatment.
The infection often comes back after treatment. To keep it from coming back, doctors may have you use special soap or apply antifungal cream once a month.
