About this ingredient
Rice bran extract is derived from the pericarp and germ fractions of milled Oryza sativa. Long used in Japanese household skincare via togijiru (rice-rinsing water) and nukabukuro (rice-bran poultices). The extract concentrates gamma-oryzanol, ferulic acid, tocopherols, and B-vitamins, and pairs well with other rice-derived materials.
