Pentapeptide-3 is a powerful yet safe wrinkle-relaxer that acts similarly to curare, the powerful paralytic nerve agent. As with curare, this powerful peptide acts at the post-synaptic membrane. The peptide prevents release of the sodium ion necessary for muscle receptors to receive nerve signals that cause the muscles to contract. The muscle stays relaxed and lines are not formed. Used in CSRx Retinol Peptide Resurfacing Complex.« Back to Glossary Index
