^{【Product Overview】 We are a specialized global supplier of Tripeptide-10 Citrulline, a synthetic tetrapeptide famously known by the trade reference Decorinyl. This peptide is designed to mimic the function of Decorin, a small proteoglycan that binds to collagen fibrils. In aging skin, truncated decorin leads to disorganized collagen bundles. Tripeptide-10 Citrulline regulates fibrillogenesis, ensuring that collagen fibers are uniform in diameter and regularly spaced, resulting in skin that is not only firmer but also more supple and resilient.}

^{【Key Advantages】}

^{Collagen Organization (Quality Control): Boosting collagen synthesis is not enough; the fibers must be organized to be functional. Tripeptide-10 Citrulline acts as a "guide," regulating the assembly of collagen fibrils to prevent chaotic clumping (which feels like stiffness). It ensures the skin's structural network is neat and robust.}

^{Decorin Mimicry: It specifically targets the binding sites on collagen fibrils that Decorin would naturally occupy. This compensates for the age-related decline of functional Decorin, restoring the "young" structure of the dermis.}

^{Improved Suppleness: By organizing the extracellular matrix (ECM), it improves the skin's biomechanical properties. Clinical data shows a significant increase in skin plasticity and suppleness, making it ideal for "elasticity-boosting" formulations.}

^{Perfect Partner for Matrixyl: This is the ultimate "Quality Assurance" ingredient to pair with collagen boosters (like Palmitoyl Pentapeptide-4). One ingredient produces the raw material (Collagen), and Decorinyl organizes it into a strong building.}

^{【Logistics & Service】}

^{Cosmetic Grade Quality: Manufactured under strict cGMP guidelines for cosmetic ingredients, ensuring low bio-burden and absence of heavy metals.}

^{Global Export: We are experienced in shipping cosmetic peptides globally. We provide full HS Code support (typically 2937.19 or 3504.00) and COA/MSDS documentation for your regulatory files.}

^{Formulation Advice: Stable in aqueous solutions and emulsions. Can be added at the final stage of manufacturing (below 40°C).}
