Galactomyces Ferment

Galactomyces ferment filtrate is a yeast-derived fermentation filtrate used prominently in Asian skincare. It contains a complex mixture of fermentation metabolites rather than one defined active molecule, so composition depends on the fermentation and filtration process.

Human studies of specific Galactomyces-ferment-filtrate-containing skincare systems report improvements in hydration, roughness, pigmentation and wrinkle measures. Those results support the potential of the ingredient category, but they are tied to particular formulations and do not prove that every Galactomyces product will perform identically.
