Formula IngredientSkin Conditioning AgentSaccharomyces Ferment
INCI: Saccharomyces Ferment
Saccharomyces ferment is a skin conditioning ingredient derived from the fermentation of Saccharomyces cerevisiae (baker's/brewer's yeast). The fermentation process produces a complex mixture rich in amino acids, peptides, vitamins (particularly B vitamins), minerals, beta-glucans, and enzymes. It functions as a humectant and skin conditioning agent, helping to hydrate, soothe, and strengthen the skin barrier. It is also used in natural deodorant formulations due to its enzymatic ability to bio-convert odour-causing compounds.
