About
Water filtered through yeast fermentation — delivers amino acids and beta-glucans for mild conditioning. Popular in Asian-market products.
Saccharomyces water is water obtained from the fermentation or culture of Saccharomyces yeast strains, carrying low levels of yeast-derived amino acids, peptides, beta-glucans, B-vitamins, and organic acids. Positioned as a skin-conditioning and hydration-supporting ingredient, it is popular in K-beauty and J-beauty products. It differs from Saccharomyces ferment filtrate primarily in concentration of active metabolites. There is no dedicated SCCS opinion; safety is inferred from long use history of Saccharomyces-derived ingredients. Yeast allergens are a rare but possible reactivity concern. No GHS hazards at cosmetic concentrations.
