Hydrolyzed Rice Bran Protein

Hydrolyzed rice bran protein is derived from rice bran—the outer layer of the rice grain—that has been broken down into smaller protein fragments through hydrolysis. This process makes the protein molecules small enough to penetrate or interact with the skin surface, rather than remaining as a large, inert film.In skincare formulations, it functions primarily as a conditioning agent, helping to improve skin texture and support the skin's natural moisture barrier.

Hydrolyzed rice bran protein works by forming a lightweight conditioning film on the skin. The small molecular size of hydrolyzed protein allows it to deposit onto the skin surface, where it helps to smooth the outer layer and reduce transepidermal water loss (moisture evaporation from the skin).Unlike occlusive ingredients that sit heavily on the skin, hydrolyzed proteins typically provide a more breathable conditioning effect, making them suitable for a range of skin types.

Hydrolyzed rice bran protein is typically used as a supporting conditioning ingredient in serums, moisturisers and body care products rather than as a primary active. It can be used daily as part of your regular skincare routine. It pairs well with other hydrating and barrier-supporting ingredients.

Hydrolyzed rice bran protein is generally well-tolerated and considered safe for cosmetic use. Those with rice allergies should avoid products containing this ingredient.
