What it is
Saccharomyces Cerevisiae Extract is obtained from the yeast Saccharomyces cerevisiae, the same species used in baking and brewing. It is rich in amino acids, peptides, polysaccharides, vitamins, and minerals that contribute conditioning and moisture-binding benefits to the skin. In cosmetics it is used as a fermentation-derived additive that supports a soft, hydrated feel.
Safety & warnings
Generally well tolerated in cosmetic use. Sensitivity to yeast-derived ingredients is uncommon. It is a water-compatible ingredient and is not associated with comedogenicity.
Origin & sourcing
Biotechnological, derived from cultured Saccharomyces cerevisiae yeast. The cells are processed and extracted to release their soluble components, yielding a complex of yeast-derived nutrients.
History
Yeast and fermentation-derived ingredients have a long history in skincare, particularly in East Asian cosmetics, where fermented preparations are valued for their nutrient-rich profiles.
