Decorin-mimetic fibrillogenesis peptide · found in Decorinyl-class actives · choose base, strength, and preservation
The INCI peptide found in supplier-branded Decorinyl (Lipotec / Lubrizol) actives. We supply our own 0.2% (1X) and 2% (10X) suspensions; we do not sell or represent Decorinyl.
Lys-Asp-Ile-Cit decorin mimic · CAS 117933-89-8
Tripeptide-10 Citrulline (Lys-Asp-Ile-Cit-NH2) is a decorin-mimetic tetrapeptide used in firming skincare. Published work describes it binding collagen fibrils and regulating fibrillogenesis so fibrils keep a more uniform diameter and spacing, which formulators position for suppleness, resilience, and elasticity in mature skin.
Market context: this is the INCI peptide found in supplier-branded Decorinyl (Lipotec / Lubrizol) actives, and it also appears in Decorinyl-class blends such as Trylagen (Lubrizol). Formulate Labs supplies Tripeptide-10 Citrulline in our own made-to-order suspensions. We do not sell, stock, or represent those trade names.
Formulate Labs offers it as a water-soluble suspension in glycerin / water or Sea Kelp Bioferment. Use about 5% of the 0.2% (1X) grade, or 0.5% of the 2% (10X) lab concentrate, for roughly 0.01% peptide in the finished formula.
Hair-care note: unlike dermal-papilla or DEJ-anchoring peptides, Tripeptide-10 Citrulline has no primary hair application - follicle growth and keratin shaft structure do not depend on collagen fibrillogenesis. Target facial and body firming skincare.*
These attributes are assessments based on the ingredient deck and the supplier information available to us. They are not third-party certifications (no Kosher, Halal, Vegan, or similar certifying body has audited or issued a certificate for this material). If your finished product requires a specific certified status, please reach out and we’ll walk through what we can document.
Every lot is produced to order in our AI-powered robotic factory. Nothing sits on a warehouse shelf going stale - you get a date-of-manufacture-fresh batch every time.
Tripeptide-10 Citrulline is the INCI name for the active ingredient; trade names such as Decorinyl refer to supplier-branded actives, which Formulate Labs does not sell or represent.
Tripeptide-10 Citrulline's efficacy in collagen organization and skin rejuvenation is supported by robust scientific research, including peer-reviewed studies that validate its mechanism as a decorin-mimetic peptide found in Decorinyl-class actives. These are independent, third-party papers we link for formulators evaluating mechanism, tolerability, and published panel data. We did not conduct this research and do not guarantee replication in your finished formula.
In vitro and in vivo testing confirmed the peptide regulates collagen fibrillogenesis and increases skin suppleness.
