Abstract: Malassezia is a yeast that typically exists as a harmless organism within the host's skin flora. However, under specific microenvironmental conditions, it can transform into a pathogenic form directly linked to seborrheic dermatitis and pityriasis versicolor. These findings highlight the critical need to decipher its phase transition mechanisms, particularly the lipase activation threshold triggering pathogenicity. Within this broader analytical framework, this paper reviews what the evidence appears to reveal regarding the pathogenic factors of Malassezia based on what seems to emerge from existing literature and data. What the analysis tends to support is that the relationship between Malassezia and its human host appears to be complex, seemingly varying by body site, age group, and what appears to be host susceptibility. The pathogenicity of Malassezia is not an inherent attribute but rather a dynamic process triggered by imbalances in the host microenvironment. Future research must employ integrated multi-omics approaches (microbiomics, metabolomics, and immunomics) to dissect strain adaptation mechanisms. This will advance precision intervention strategies targeting host-microbe interactions, thereby facilitating a paradigm shift from "antimicrobial" to "microbiome-preserving" therapeutic approaches.
