^{【Product Overview】 We are a specialized global supplier of Myristoyl Tetrapeptide-12, a potent lipo-peptide engineered for the specific enhancement of eyelashes and eyebrows. While many peptides focus on length, Myristoyl Tetrapeptide-12 targets the thickness and density of the hair shaft. It is the ideal strategic partner to Myristoyl Pentapeptide-17. We provide high-purity powder to formulators looking to create "3D Effect" eyelash serums that claim both length and volume.}

^{【Key Advantages】}

^{The "Volume" Specialist: This peptide works by stimulating the expression of keratin genes distinct from those targeted by other peptides. It focuses on the structural integrity of the lash, making individual hairs appear thicker and fuller (increasing the diameter of the hair shaft).}

^{The Perfect Synergy (The "Combo" Strategy): It is rarely used alone. The industry standard for premium lash serums is to stack Myristoyl Tetrapeptide-12 with Myristoyl Pentapeptide-17. This dual-peptide approach targets the follicle from two different biological pathways, maximizing clinical results and justifying a higher retail price point.}

^{Eyebrow Restoration: Due to its ability to improve density, it is exceptionally effective in Eyebrow Serums, helping to fill in sparse areas and create the "Bold Brow" look that is currently trending.}

^{Deep Penetration: Like its counterpart, the attached Myristoyl fatty acid chain ensures the peptide can penetrate the oily sebum of the eyelid and reach the hair root (Dermal Papilla) efficiently.}

^{【Logistics & Service】}

^{Cosmetic Grade Quality: Manufactured under strict cGMP guidelines for ophthalmic safety.}

^{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.}

^{Formulation Advice: We recommend a 1:1 ratio with Myristoyl Pentapeptide-17 for a comprehensive "Length & Volume" claim.}
