Argireline- Summary
- Carnosine is an endogenous dipeptide (beta-alanine + histidine) found in high concentrations in muscle and brain. It is a potent anti-aging molecule with broad spectrum antioxidant, anti-glycation, anti-carbonylation, and metal chelating properties, making it one of the most protective naturally occurring dipeptides.
- 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
- ~1.5 minutes (rapidly hydrolyzed to beta-alanine and histidine by carnosinase in blood; tissue levels maintained via constant synthesis)
- N/A — topical application; effect duration linked to formulation contact time
- Admin Route
- Oral, Topical
