The ingredient was developed to deliver a smooth, skin-friendly particle and to concentrate beauty-related components such as γ-oryzanol, vitamins and ceramides while retaining rice bran’s natural profile. Kaken produced the ferment by micronising rice bran to a fine texture, then fermenting it for 18–24 hours to boost lactic-acid-bacterial activity and enhance functional compounds. The resulting Rice Bran Ferment was positioned for incorporation into [cleansing formulas](https://www.trendhunter.com/trends/byoma-foaming-rice-deep-cleanser) to improve moisture retention, reduce roughness and leave a comfortable post-cleanse skin feel. For brands and consumers, the ingredient pairs [traditional Japanese fermentation knowledge](https://www.trendhunter.com/trends/the-protein-brewery-fermotein) with modern processing, offering an [upcycled, culturally rooted option](https://www.trendhunter.com/trends/red-quinoa-cleansing-sorbet) for gentle high-performance cleansers. Its combination of enhanced skin benefits and sustainability fits rising demand for clean, heritage-backed actives.
