What Is Saccharomyces/Rice Ferment Filtrate?

Saccharomyces/Rice Ferment Filtrate is produced through the co-fermentation of Saccharomyces yeast with rice, combining the benefits of both fermentation pathways. The yeast produces vitamins, amino acids, and peptides while the rice fermentation releases kojic acid, ferulic acid, and rice bran nutrients. This synergistic co-fermentation provides brightening (kojic acid), hydration (amino acids), gentle exfoliation (enzymes), and antioxidant protection (ferulic acid). A modern evolution of traditional sake fermentation for skincare.
