What It Does

A lightweight oil extracted from rice bran, rich in vitamin E and gamma-oryzanol. A versatile moisturizer rooted in Japanese rice culture.

Rice bran oil, extracted from the germ and inner husk of rice, is a lightweight oil rich in vitamin E (especially tocotrienols), fatty acids, and antioxidants like ferulic acid and gamma-oryzanol. It has been used in Japanese cuisine and skincare for generations. Rice bran oil is prized for its stability, mild scent, and non-greasy texture.

Rice bran oil provides emollient hydration, antioxidant protection, and UV-protective benefits from gamma-oryzanol. It absorbs quickly without leaving a heavy residue, making it suitable for all skin types including oily skin. The high vitamin E content makes it particularly effective for mature or sun-damaged skin.

Japanese skincare uses rice bran oil in cleansing oils, facial oils, and moisturizers. Brands like DHC, Shiseido, and Komenuka Bijin feature it prominently. It represents the Japanese tradition of utilizing every part of the rice plant for practical benefits. Rice bran oil is also popular in cooking, reflecting the Japanese philosophy that what is good for the body is good for the skin.
