Science
Mechanism of Action
RH-RICE EXTRACT operates through a multi-pronged mechanism to enhance skin health. Its amino acid content actively hydrates and maintains moisture levels within the skin. Bioactive compounds like phenolic compounds, betaine, squalene, and tricin contribute to anti-aging, anti-inflammatory, and photoprotective actions, alongside skin brightening effects. Fermented derivatives introduce organic acids, such as lactic acid, facilitating gentle exfoliation, supporting the skin's natural pH, and fortifying the acid mantle. Furthermore, the extract promotes collagen and elastin synthesis, enhancing fibroblast migration and improving overall skin mechanical properties through its antioxidant and anti-inflammatory lipids and polyphenols.

Key findings
- 01 A 5% concentration of red rice extract in lotion formulations demonstrated excellent viscosity, homogeneity, and a skin-compatible pH range (5.0-5.5), indicating suitability for cosmetic applications.
- 02 Fermented rice bran extracts significantly boosted type I collagen synthesis, lowered MMP-1 expression, and inhibited IL-1α production in photoaged human fibroblast models. In vivo studies confirmed protection against UVA-induced aging in mice, characterized by reduced wrinkle formation and improved collagen organization.

Stability
RH-RICE EXTRACT integrates seamlessly into both water- and oil-based formulations while maintaining color stability. Formulations containing this extract typically achieve a skin-friendly pH between 5.0 and 5.5. Fermented rice ingredients tend to yield more stable, pH-balanced formulations, with specific fermented red yeast rice extract exhibiting enhanced stability in acidic environments, showing only a 3.80% degradation rate over 3 hours at an initial pH of 5.75.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has evaluated general rice-derived ingredients, such as Hydrolyzed Rice Extract and Oryza Sativa (Rice) Extract. However, specific data regarding 'RH-RICE EXTRACT' for a definitive CIR status (e.g., 'safe as used' or maximum concentration) remains insufficient. Globally, rice-derived components are widely considered safe, non-irritating, and hypoallergenic for topical use. No specific SCCS status was found.
