Certificate Reference
For continuity with the current catalog, this page links to laboratory documentation for a component or a closely related product. The linked certificate is a reference only and is not represented as the batch-specific COA for Matrixyl.
Overview
Matrixyl is commonly used to refer to palmitoyl pentapeptide-4, a lipidated signaling peptide developed for extracellular-matrix and dermal-fibroblast research. The palmitoyl group improves association with lipid environments, while the peptide sequence is studied for its influence on matrix-related gene expression.

Research Focus
WHAT THIS FORMULA FEATURES
The research focus is collagen and extracellular-matrix signaling rather than simple antioxidant activity. In vitro work with cosmetic peptides including palmitoyl pentapeptide-4 has examined fibroblast viability, proliferation, and expression of collagen- and matrix-remodeling genes.
EXPECTED RESEARCH READOUTS
Common endpoints include fibroblast proliferation, COL1A1/COL3A1 and other ECM-related gene expression, procollagen/collagen output, fibronectin, matrix metalloproteinases, and comparison with unstimulated or growth-factor controls.
Research endpoints described above reflect published or model-based scientific observations and are not guaranteed outcomes. This product is strictly for research purposes only. Not approved for human or animal use.
