Matrixyl 200mg (Topical)

Matrixyl is a palmitoylated pentapeptide (Pal-Lys-Thr-Thr-Lys-Ser) that is studied for its regulatory effects on the synthesis of the extracellular matrix and skin signaling. It increases the expression of collagen and fibronectin genes in cultured fibroblasts via TGF-β- and integrin-mediated signaling pathways. Matrixyl serves as a topical research model for investigating peptide-driven cell communication, matrix remodeling, and mechanisms of fibroblast activation.

Matrixyl is often referred to as Palmitoyl-Pentapeptide-4 (often written as Pal-KTTKS), a lipidated peptide motif that is used as a laboratory tool compound to investigate the biology of the extracellular matrix (ECM) and the behavior of peptide–lipid conjugates in controlled experimental systems. In research workflows, lipidation (e.g., palmitoylation) is frequently used to alter the hydrophobicity of peptides, membrane association, and local microenvironment interactions, enabling a mechanistic exploration of structure–function relationships in peptide-based modulators.
