What is the difference between Argireline and Matrixyl?

Argireline: Inhibits SNARE complex formation in facial muscles; reduces acetylcholine release locally; relaxes expression lines without systemic effects Matrixyl: Palmitoylated pentapeptide fragment of collagen I; binds TGF-β receptors on fibroblasts; upregulates collagen I, III, and fibronectin; procollagen production via MAPK pathway
