Saccharomyces Ferment

Saccharomyces ferment ingredients are yeast-derived fermentation products used in skincare for hydration, conditioning and radiance support. Depending on the INCI, a product may contain ferment filtrate, lysate or extract, each representing a different processed material.

Fermented and postbiotic skincare is an active research area, but clinical data are preparation-specific and much less standardized than the marketing category suggests. Saccharomyces ferment should be evaluated as a supportive conditioning ingredient rather than evidence that a product modifies the skin microbiome in a predictable way.
