Science
Mechanism of Action
Oryza Sativa Bran Water functions as a natural humectant and emollient, aiding the skin in moisture retention to maintain softness. Its rich composition of vitamins and antioxidants, including ferulic acid, vitamin E, and gamma-oryzanol, actively neutralizes free radicals, thereby protecting skin cells from environmental damage and supporting the integrity of collagen to minimize the appearance of fine lines. This ingredient also fortifies the skin's natural moisture barrier through components like linoleic acid and other lipids, effectively preventing transepidermal water loss. Furthermore, it gently exfoliates due to natural phytic acid content and contributes to fading hyperpigmentation by inhibiting excessive melanin production, while helping to balance the skin's natural pH and encourage cellular renewal.

Stability
For optimal stability and to inhibit enzymatic rancidity, it is recommended to add Oryza Sativa Bran Water to formulations when the temperature is below 50°C. While the optimal pH for endogenous lipases in rice bran is around 7.5, maintaining a lower pH within the 4.5-7 range can aid in preserving ingredient integrity.
