Matrixyl definition
Matrixyl is a cosmetic lipopeptide used in extracellular-matrix and dermal-fibroblast research workflows. Matrixyl is classified as a palmitoylated cosmetic signal peptide. Palmitoyl pentapeptide-4, commonly written Pal-KTTKS, a palmitic-acid conjugated collagen-fragment signal peptide.. Supplied by Nexus Laboratory for in-vitro research use only — not approved for human or veterinary therapeutic use.

Research context.
Because Matrixyl is a trade name, final labeling should use the chemical name palmitoyl pentapeptide-4 and verify whether the supplier uses the Pal-KTTKS molecule rather than another Matrixyl-family peptide.
Verification standard.
Every Nexus Laboratory batch ships with a Certificate of Analysis documenting HPLC purity (target ≥98%), mass spectrometry identity (expected versus observed mass), and endotoxin screening — verified by third-party laboratory testing and publicly archived. Review Nexus lab verification.
Matrixyl is part of the Nexus Cosmetic & Skin catalog. Copper peptides and cosmetic signaling compounds. Each listed variant is priced from the consolidated Nexus catalog and intended for qualified research use only.
