Science

Mechanism of Action

Oryza Sativa Extract delivers its comprehensive benefits through a synergistic blend of active compounds, including phenolic compounds, flavonoids, gamma-oryzanol, tocopherols (Vitamin E), ferulic acid, anthocyanins, proanthocyanidins, and carotenoids. These components collectively act as potent antioxidants, effectively scavenging free radicals and protecting against UV-induced oxidative damage. Its skin brightening and depigmenting actions are achieved by reducing melanin overproduction and inhibiting melanin biosynthesis, further supported by the gentle exfoliating properties of natural phytic acid. The extract deeply moisturizes and hydrates the skin via amino acids, natural oils, fatty acids (such as linoleic acid), squalene, and polysaccharides, which reinforce the skin's barrier. Additionally, its B vitamins and phytocompounds provide significant anti-inflammatory and soothing effects to calm irritation and redness, while its antioxidant defense also contributes to anti-aging by protecting collagen integrity and diminishing the appearance of fine lines. The ingredient also functions as a chelating agent.

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that Oryza Sativa Extract and other rice-derived ingredients are safe for use in cosmetic formulations under current practices and concentrations, generally considering them non-allergenic. The FDA has also recognized rice bran extract as 'Generally Recognized As Safe' (GRAS) for specific food applications (e.g., as a moisture retention agent) at a maximum level of 1.25% by weight. The CIR Expert Panel recommends that trace levels of pesticides and polychlorinated biphenyls (PCBs) in rice-derived cosmetic ingredients should not exceed established limits.
