Oryza Sativa (Rice) Bran Extract

Derived from the seed of Oryza sativa, a type of rice originating in China, purple rice extract helps preserve hyaluronic acid content in the skin. It supports hydration by inhibiting the body's ability to break down hyaluronic acid, allowing more of this moisture-binding compound to remain active in the skin.

Rice bran extract works through multiple mechanisms. Its phenolic compounds act as antioxidants, helping to neutralise free radicals that can contribute to skin ageing. The extract also contains natural emollients and conditioning agents that form a protective layer on the skin, reducing transepidermal water loss and maintaining hydration.Some research suggests that fermented rice bran extract may stimulate the synthesis of collagen and elastin at a cellular level, though this mechanism is not fully understood and requires further investigation in human studies.

Rice bran extract is most effective when used as part of a consistent skincare routine. It works well alongside other hydrating and antioxidant ingredients. There is no specific guidance on optimal usage frequency, but as with most conditioning ingredients, daily use in appropriate formulations is generally safe and may yield better results over time.

Rice bran extract is considered safe for cosmetic use across various product types. It is generally well-tolerated and does not typically cause irritation, though those with known rice sensitivities should avoid products containing this ingredient.
