Saccharomyces Ferment

Saccharomyces Ferment is a fermented ingredient derived from yeast, often Saccharomyces cerevisiae. The fermentation process breaks down complex molecules into smaller, more bioavailable compounds like amino acids, peptides, and organic acids. These components can help to hydrate the skin, provide antioxidant benefits, and support a healthy skin microbiome, contributing to overall skin vitality.
