What is Galactomyces?

Galactomyces Ferment Filtrate (GFF) is a fermented yeast extract that brightens, hydrates, and refines skin texture. It's the star ingredient in many First Treatment Essences. The fermentation process creates a nutrient-rich filtrate packed with amino acids, vitamins, and minerals that boost skin's natural radiance. SK-II's Pitera (a proprietary form of galactomyces) made this ingredient famous worldwide.
