Acetyl Octapeptide-3
An extended version of Argireline with two additional amino acids, designed to interact with SNAP-25 protein more efficiently. Inhibits SNARE complex formation to relax muscles driving expression wrinkles. Clinical evidence suggests greater potency than Argireline at comparable concentrations.
Topical serum 4–8%, AM and/or PM. Most potent applied to expression-prone areas before lighter serums set.
