What it is
Rice Ferment Filtrate is the filtered liquid produced when rice is fermented, a process related to traditional sake brewing. It is used in skincare and sunscreens as a skin-conditioning ingredient and humectant, often promoted for a smooth, hydrated feel. The fermentation yields a mix of small molecules such as amino acids and other water-soluble components.

Origin & sourcing
Natural in origin; derived from rice (Oryza sativa) through fermentation, then filtered to obtain the liquid.
History
