Oryza Sativa Extract comes from the rice grain, Oryza sativa. Rice extract has wound healing, antioxidant, anti-inflammatory, and hydrating properties.
Rice grains contain numerous antioxidants which may help with anti-aging, such as vitamin E. Antioxidants help stabilize free-radical molecules. Unstable free-radical molecules may damage your skin cells and accelerate signs of aging.
A study from 2002 found rice to help increase the rate of wound healing. The same study found an improvement of skin barrier function in the patients after taking rice baths.
Numerous in-vitro studies have found rice water to help decrease sun damage by increasing collagen production and inhibiting the process of tyrosinase.
Long story short- tyrosinase is an enzyme that controls melanin production. Our bodies start producing melanin (AKA tanning) when exposed to UV radiation to protect against damage. Rice water is found to partially block this process.
Though more research is needed on rice's ability to help with UV protection, recent studies seem promising.
Wondering why rice is hydrating? The protein in rice have emollient properties. Emollients create a barrier on the skin to trap moisture in, keeping your skin moisturized.
Some rice extract may have mildly-exfoliating properties. These are mainly limited to Oryza Sativa (Rice) Bran and Oryza Sativa (Rice) Germ Powder.
This rice was first cultivated in China over 10,000 years ago. Many cultures throughout Asia have used rice water on skin and hair for centuries.
