What is Malassezia

Malassezia yeasts are members of the microbiota of healthy human skin. Malassezia Folliculitis is fungal skin condition caused by Malassezia yeasts that infects hair follicules. The infection causes acnelike breakouts on the t-zone area of the face, shoulders, chest and back.

These breakouts appear in clusteres of small whiteheads, often accompanied by itchiness and inflammation. Due to similarities in appearance, Malassezia overgrowth is often misdiagosed as common acne and traditional acne solutions are used as treatment. Yet whereas typical acne is caused by bacteria--Malassezia is a fungal issue.

If treated as common acne, the condition may persist for many years without resolution.
