Yeast Ferment Extract
What is Yeast Ferment Extract?
Yeast Ferment Extract originates from the controlled fermentation of yeast, typically Saccharomyces species, yielding a bioactive mixture rich in amino acids, peptides, vitamins, minerals, and polysaccharides like beta-glucans. In cosmetics, it belongs to the skin conditioning category, where it acts primarily as a humectant and emollient. This extract draws moisture into the skin, helping to reinforce the barrier function and promote a supple texture. Formulators incorporate it into creams, serums, and masks at low levels to enhance product feel and stability. Its gentle profile stems from natural fermentation processes that concentrate nourishing components while minimizing harsh residues, making it suitable for daily routines across various formulations.
