Hydrolyzed Rice Bran Extract
INCI: Hydrolyzed Rice Bran Extract
A gentle, antioxidant-rich extract that soothes and hydrates, ideal for sensitive or dry skin types.
In plain English
Hydrolyzed rice bran extract is made by breaking down rice bran (the outer layer of a rice grain) into smaller, skin-friendly pieces. This process makes it easier for your skin to absorb the beneficial compounds, like vitamins, minerals, and antioxidants. It helps calm irritation, provides light hydration, and protects skin from environmental stress. Think of it as a gentle, nourishing meal for your skin that also helps it stay comfortable and resilient.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.

Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A natural extract obtained from the bran of rice grains (Oryza sativa) that has been hydrolyzed, or broken down, to make its nutrients more accessible to the skin. It contains a mix of vitamins (especially vitamin E and B vitamins), ferulic acid, and other antioxidant compounds.
How it works
The hydrolyzed peptides and amino acids from the rice bran help attract and hold moisture to the skin's surface, acting as a humectant. The antioxidants, such as ferulic acid and gamma-oryzanol, neutralize free radicals that can cause premature aging. Additionally, the extract has mild anti-inflammatory properties that can help calm redness and irritation.
Pros
Gentle and soothing
Hydrolyzed rice bran extract is very well-tolerated, even by sensitive or reactive skin types, helping to calm redness and discomfort without stinging.
Antioxidant protection
It delivers a blend of antioxidants like ferulic acid and vitamin E, which help defend skin against pollution and UV-induced free radical damage.
Cons and cautions
Modest hydration alone
While it provides some moisture, it is not a heavy-duty humectant or emollient, so very dry skin may need additional hydrating ingredients like glycerin or ceramides.
Limited clinical evidence
Most research on rice bran extract focuses on oral consumption or general antioxidant activity; fewer studies specifically examine its topical cosmetic benefits in humans.
Best for
- People with sensitive or easily irritated skin looking for a gentle soothing ingredient
- Anyone wanting a lightweight antioxidant boost in their routine
Use caution if
- Individuals with a known allergy to rice or rice-derived ingredients
