What it is
Saccharomyces ferment is produced by fermenting substrates with Saccharomyces yeast and collecting the resulting metabolite-rich fraction, which contains amino acids, peptides, and other small water-soluble compounds. In cosmetics it is used as a skin-conditioning and moisture-supporting ingredient and is a common feature of fermentation-positioned Korean and Japanese formulas. It is typically used in the water phase.
Safety & warnings
Yeast ferment ingredients are generally well tolerated, though as biologically complex fermentation products they may occasionally cause sensitivity in reactive individuals, who may wish to patch test. It is not associated with comedogenicity.
Origin & sourcing
Derived from the fermentation of Saccharomyces yeast, yielding a complex aqueous fraction of fermentation metabolites.
