^{【Product Overview】 We are a premier global supplier of Myristoyl Pentapeptide-4, a highly effective signaling lipo-peptide engineered for eyelash and eyebrow enhancement. Structurally similar to the famous Palmitoyl Pentapeptide-4 (Matrixyl) but modified with a Myristic Acid tail for targeted follicle penetration, this peptide is designed to significantly stimulate the expression of keratin genes. We provide high-purity powder to formulators creating premium lash growth serums and brow densifiers.}

^{【Key Advantages】}

^{Targeted Keratin Stimulation: Myristoyl Pentapeptide-4 is a signal peptide that specifically boosts the synthesis of Keratin proteins within the hair shaft. By mimicking the natural biological signals, it encourages the follicle to produce hair that is longer, thicker, and more resilient to breakage.}

^{Excellent Bioavailability: The attachment of the Myristoyl (C14) fatty acid chain transforms the water-soluble peptide into a lipophilic molecule. This ensures superior absorption through the lipid-rich layers of the eyelid and eyebrow skin, delivering the active ingredients directly to the hair root (Dermal Papilla).}

^{The "Cocktail" Strategy: It is an excellent ingredient to pair with Myristoyl Pentapeptide-17. While both target keratin, using different peptide sequences allows brands to market a "Multi-Peptide Complex" (e.g., "Contains 3 Growth Peptides"), which is a powerful selling point for high-end consumers.}

^{Safety & Compliance: A safe, non-drug alternative to prostaglandin analogues. It causes no iris discoloration or orbital fat loss, making it suitable for global cosmetic markets and "Clean Beauty" certifications.}
