A hydrating plant extract. Safe.
Oryza Sativa (Rice) Lees Extract is an extract from rice lees, the residue left after sake fermentation. It is rich in amino acids, sugars and fermentation derivatives, and in cosmetics it is used as a hydrating ingredient supporting a more even tone. It appears in serums, essences and ferment-inspired creams. On efficacy, an honest read. The amino acids and sugars humectate the surface and improve feel, and the fermentation heritage has appeal, but clinical evidence for tone brightening is limited. It is a supporting hydrating active with a light touch on radiance, not a depigmenting agent with solid backing. For topical use in pregnancy and breastfeeding there are no risk signals. Systemic absorption from skin is minimal, so it can be used in these stages. Tolerance is good. Low irritation and low allergy potential, suitable for sensitive skin. Most people see no reactions.
