Rice Ferment Filtrate (Sake)
What is Rice Ferment Filtrate (Sake)?
Rice Ferment Filtrate (Sake) is a clear liquid derived from fermenting rice grains with yeast, mirroring the initial stages of traditional Japanese sake brewing. This process breaks down rice starches into beneficial metabolites like amino acids, polypeptides, ferulic acid, and trace vitamins, enriching the filtrate. Classified as a skin conditioning agent in cosmetics, it appears in toners, essences, and creams at low concentrations. It works by adhering lightly to the skin, aiding water retention and bolstering the moisture barrier through humectant and emollient properties. Fermentation boosts the solubility and absorption of rice's natural components, supporting overall skin suppleness without heaviness.
