In our reference data, Yeast/Rice Fermentation Filtrate can feed Malassezia (fungal acne).
Yeast/Rice Fermentation Filtrate is a fermentation-derived liquid (notably associated with Galactomyces and Pitera-type filtrates) rich in amino acids, vitamins, organic acids, and minerals, used to hydrate, brighten, and improve skin texture. It is reported to support the skin barrier and may have mild antioxidant and exfoliating effects.
