Hydrolyzed Yeast Extract
What is Hydrolyzed Yeast Extract?
Hydrolyzed yeast extract originates from Saccharomyces cerevisiae yeast, which undergoes hydrolysis to break down its proteins into smaller peptides, amino acids, and nucleotides. This process creates a water-soluble ingredient commonly used in skincare formulations like creams, serums, and masks within the skin conditioning category. It functions primarily as a humectant, drawing moisture to the skin's surface and aiding in hydration retention. Additionally, its bioactive components support skin barrier integrity by promoting lipid organization and providing emollient effects that enhance smoothness. In cosmetic products, it appears at low concentrations to deliver these conditioning benefits without altering texture or stability, making it suitable for various formulations targeting daily skin maintenance.
