Common Name(s): Rhizopus/saccharomyces/rice ferment,rhizopus and saccharomyces (dual-organism traditional fermentation) ferment,rice grain (whole) ferment filtrate
DESCRIPTION
What It Does: Delivers bioactive compounds from rhizopus and saccharomyces (dual-organism traditional fermentation) fermentation to condition and support skin health.
Why It's Used: Fermentation of rice grain (whole) by rhizopus and saccharomyces (dual-organism traditional fermentation) produces enriched filtrate with enhanced bioavailability of skin-beneficial compounds.
How It Works: Microbial fermentation transforms rice grain (whole) components into smaller, more bioavailable peptides, organic acids, and metabolites that support skin barrier function and microbiome balance.

SCIENTIFIC NOTE
Traditional dual-organism rice fermentation using rhizopus (koji mold) and saccharomyces yeast; rhizopus produces proteases and amylases that break down rice proteins and starch; combined fermentation (similar to sake/rice wine production) produces kojic acid, ceramide precursors (glucosylceramide), and ferulic acid from rice bran.
