Science
Mechanism of Action
Saccharomyces/Hydrolyzed Rice Bran Ferment Filtrate provides the skin with an easily absorbed complex of antioxidants, vitamins, minerals, amino acids, peptides, and organic acids. It acts as a powerful antioxidant, neutralizing free radicals to shield against environmental damage and decelerate visible signs of aging. The ingredient profoundly nourishes and hydrates, reinforcing the skin's natural protective barrier. It stimulates cellular regeneration, refines skin texture, and enhances radiance, while boosting collagen and elastin synthesis and promoting fibroblast migration for improved skin elasticity. Brightening is achieved through ferulic acid's ability to inhibit tyrosinase activity and reduce melanin production. Additionally, it possesses anti-inflammatory properties, functions as a humectant, and can help balance the skin's microbiome, potentially offering astringent and anti-sebum effects.

Key findings
- 01 A 30-day clinical evaluation demonstrated that a 20% dilution of an alcohol-free rice bran fermentation solution led to a 9.29% improvement in skin whitening and a 44.31% increase in moisturization. Concentrations from 1% to 15% also yielded positive, albeit lesser, effects on both parameters, with no observed cytotoxic impact.
- 02 Studies on brown rice filtrate fermented with Saccharomyces cerevisiae revealed a significant increase in hyaluronic acid (HA) levels and enhanced expression of hyaluronan synthase 2 and aquaporin 3 (AQP3) in HaCaT cells, crucial components for maintaining optimal skin hydration.
- 03 Fermented rice bran extract has been shown to promote the synthesis of collagen and elastin, enhance fibroblast migration, and improve the skin's mechanical properties, contributing to anti-aging benefits.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that rice-derived ingredients, including similar hydrolyzed rice bran extracts, are safe for cosmetic applications. Yeast-derived ingredients generally exhibit an excellent safety profile, with some Saccharomyces ferment filtrates utilized at concentrations up to 90.7% in leave-on products. This ingredient is widely tolerated with no obvious cytotoxic effects observed in studies.
