Peptide Comparison

EGF vs Matrixyl

Q: What is the difference between EGF and Matrixyl?

EGF: Binds EGFR (EGF receptor / ErbB1), activating RAS/MAPK and PI3K/Akt signaling cascades. Matrixyl: Palmitoylated pentapeptide fragment of collagen I; binds TGF-β receptors on fibroblasts; upregulates collagen I, III, and fibronectin; procollagen production via MAPK pathway

Both are Skin & Cosmetic peptides.
