Argireline- Summary
- Cortagen is a synthetic tetrapeptide (Ala-Glu-Asp-Pro) developed at the St. Petersburg Institute of Bioregulation as a cardioprotective and vascular bioregulator. It stimulates repair of cardiac and vascular tissue, with demonstrated benefits for coronary artery disease, atherosclerosis, and cardiac aging.
- Argireline is the most widely researched topical 'Botox-alternative' cosmetic peptide, an acetylated hexapeptide that inhibits neuromuscular transmission to relax facial muscles and reduce dynamic wrinkle depth by 17–27% in clinical studies.
- Half-Life
- Short peptide half-life; gene regulatory effects persist beyond peptide clearance
- N/A — topical application; effect duration linked to formulation contact time
- Admin Route
- SubQ, IM, Oral
