What can be used to treat a fungus that causes skin discoloration?

Antifungal medicine: Fungus infections of the skin usually change the skin color, but after a few to many months, the color should be back to normal. Common "ringworm", jock itch, or athlete's foot rashes are treated with over-the-counter lotriminaf cream. Tinea versicolor rash on the back and chest is treated with selsun blue shampoo. A doctor can check to be sure the rash is fungal, and give details on treatment.

Tinea Versicolor: Treatment of tinea versicolor with topical antifungals. Topical antifungal medications are the treatment of choice for tinea versicolor.
