Malassezia is a group of yeast that is most commonly found in the human skin microbiome. It is associated with both healthy skin and skin conditions like dermatitis, eczema, and dandruff [1]. While Malassezia has been identified in other locations on the human body, it is still unclear whether this detection is due to it colonizing those locations or if they have been contaminated from skin exposure [1]. There is some evidence from studies in mice that high levels could cause inflammatory bowel disease. (Adapted from Tiny Health) We consider a low or absent level of Malessezia to be optimum.
