By What is Tinea Versicolor?
The fungus Malassezia is a type of yeast found on the surface of the skin. It normally doesn’t cause any health problems. In fact, many of the microbiota (or microscopic organisms), including yeasts like Malassezia, that live in large communities on your skin help protect you from infections and other pathogens that can cause harm or disease. They live alongside your body’s cells in symbiotic relationships, with skin cells and tiny organisms supporting and benefiting each other.
Sometimes, however, this yeast can grow out of control and affect the natural color or pigmentation of your skin. When this happens, you may develop patches of skin that are lighter or darker than the surrounding skin. This condition, which isn’t contagious, is known as Tinea Versicolor, or pityriasis versicolor. The condition occurs when a type of yeast from the Malassezia family causes an infection or suppresses your immune system.
