^{【Product Overview】 We are a specialized global supplier of Acetyl Tetrapeptide-2, a bioactive tetrapeptide famously known by the trade reference Uplevity. This peptide is specifically engineered to combat the effects of gravity on aging skin. Unlike standard peptides that simply boost collagen, Acetyl Tetrapeptide-2 focuses on Elastin Assembly. It ensures that collagen and elastin fibers are correctly organized, providing the mechanical resistance needed to hold the skin up and maintain a youthful facial contour.}

^{【Key Advantages】}

^{Defying Gravity (The V-Shape Effect): Its primary selling point is "Anti-Sagging." By strengthening the skin's internal architecture, it helps lift the jowls and define the jawline, addressing the "inverted triangle" of aging.}

^{FBLN5 & LOXL1 Activation: It works by upregulating the expression of Fibulin-5 (FBLN5) and Lysyl Oxidase-Like 1 (LOXL1). These are critical proteins responsible for the proper assembly and cross-linking of functional elastin fibers. Without them, elastin is just unstructured "clumps" that offer no firmness.}

^{Dermal Cohesion: It enhances the cohesion between cells and the extracellular matrix (ECM), making the skin denser and more resistant to deformation.}

^{Mature Skin Specialist: It is the ideal ingredient for formulations targeting 50+ skin, neck creams, and body firming lotions (upper arms/thighs) where loss of firmness is the main concern.}

^{【Logistics & Service】}

^{Cosmetic Grade Quality: Manufactured under strict GMP 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: Acetyl Tetrapeptide-2 is thermostable and easy to formulate. We recommend adding it in the final cooling phase of emulsions.}

^{Regulatory Disclaimer: This product is supplied as a Cosmetic Raw Material for further manufacturing and R&D use only. It is intended for topical application and is not for injection.}
