Wash and dry the affected area. Then, apply a thin layer of the topical agent once or twice a day for at least two weeks. If you’re using shampoo, rinse it off after waiting five to 10 minutes. If you don’t see an improvement after four weeks, see your doctor. You may need a stronger medication.
Even after successful treatment, your skin color may remain uneven for several weeks, or even months. Also, the infection may return in warm, humid weather.
To help prevent tinea versicolor from returning, you can use the over the counter or the topical prescription treatment prescribed to you 1-2 times weekly.
