Spots that won't tan with the rest of your skin.
Tinea versicolor is a chronic, Malassezia-driven condition that thrives in heat and humidity. Learn what's actually going on, then build a Malassezia-safe maintenance routine from our collection of solutions that help manage symptoms between seasons.
Tinea versicolor is caused by Malassezia overgrowing on the skin and producing compounds that interfere with melanin production in the affected areas. The result is patches that are lighter or darker than your surrounding skin, often most visible after sun exposure.
It's common and harmless to your overall health. Once the yeast is back under control, the discoloration still takes time to even out, since pigment production needs time to recover.
