Oryza Sativa (Rice) Lees Extract
What is Oryza Sativa (Rice) Lees Extract?
Oryza Sativa (Rice) Lees Extract comes from the lees, the nutrient-rich sediment left after fermenting rice grains from the Oryza sativa plant during sake production. This botanical extract captures components like amino acids, vitamins, and organic compounds inherent to rice fermentation. In cosmetics, it serves mainly as a skin conditioning agent in products such as moisturizers, lotions, and masks. It functions by depositing a thin film on the skin surface or delivering humectant-like substances that help retain moisture, thereby supporting the skin's barrier and promoting a supple texture. The extract is obtained through solvent or water extraction methods to isolate these beneficial residues, making it suitable for various formulations aimed at daily skin maintenance.
