Science
Mechanism of Action
Tridecapeptide-1 operates by interfering with neuromuscular signaling at acetylcholine receptors. Upon topical application, it prevents the neurotransmitter acetylcholine from binding to its designated receptor sites, effectively blocking the signals that initiate muscle contractions. This leads to a relaxation of facial muscles, which in turn diminishes the visibility of expression lines and prevents new wrinkle formation.

Key findings
- 01 Clinical trials demonstrated a visible reduction in fine lines and wrinkles, particularly around the crow's feet area, observable as quickly as 15 minutes post-application.
- 02 Sustained application within the 1-10% concentration range contributes to long-term wrinkle reduction by consistently maintaining muscle relaxation, thereby minimizing both existing and new wrinkle formation over time.
- 03 After four weeks of twice-daily use in leave-on formulations, the peptide was also shown to enhance skin texture, resulting in a smoother complexion.
