Science
Mechanism of Action
Operating as a single-chain recombinant human peptide, SR-RICE POLYPEPTIDE-1 is structurally identical to human EGF. This allows it to stimulate fibroblast cell growth and proliferation, initiating the endogenous synthesis of collagen and other extracellular matrix components critical for skin strength and elasticity. Beyond its profound anti-aging actions, it further functions as an antimicrobial, antioxidant, humectant, and protective agent, contributing comprehensively to skin health and resilience.

Formulation
Stability
While native rice protein can have limited water solubility, this specific polypeptide form is processed to significantly enhance its aqueous solubility. Although the optimal pH for SR-RICE POLYPEPTIDE-1 stability is not explicitly defined, solubility improvements for general rice protein are often achieved within a pH range of 6.5-7.5.
Safety
Safety Profile
Direct safety assessments from CIR or SCCS for SR-RICE POLYPEPTIDE-1 are not currently available. However, plant-derived proteins and peptides are generally considered safe for cosmetic application, and rice protein is recognized for its low antigenic potential. FDA warnings concerning cosmetic products with 'rice' in their names do not specifically target this ingredient itself.
