Common Name(s): Saccharomyces lysate extract filtrate,saccharomyces lysate extract filtrate,saccharomyces postbiotic,yeast ferment active
CAS Number: N/a
DESCRIPTION
What It Does: Provides yeast-characteristic beta-glucan dectin-1 receptor stimulation, ergosterol-derived vitamin d precursors, and fermentation-biotransformed substrate metabolites.
Why It's Used: Saccharomyces yeast ferments deliver consistent postbiotic activity from well-characterised organisms with a long cosmetic safety record.
How It Works: S. cerevisiae fermentation: glycolysis → ethanol + co₂; anabolic: glucan synthesis, ergosterol pathway, mannoprotein secretion; substrate biotransformation releases bound actives.
Typically Found In: Ferment skin care,microbiome
