Overview
Argireline is classified as a cosmetic peptide peptide. Topical wrinkle reduction, SNAP-25 inhibition, muscle relaxation (neurocosmetic).
Competes with SNAP-25 (synaptosomal-associated protein 25) for binding at the SNARE complex, partially inhibiting acetylcholine release at the neuromuscular junction, reducing repeated facial muscle contractions that cause dynamic wrinkles. Applied topically, it does not cross to the dermis at meaningful concentrations.
Also known as: Acetyl Hexapeptide-3, Acetyl Hexapeptide-8, AH-3

How Does Argireline Work?
Competes with SNAP-25 (synaptosomal-associated protein 25) for binding at the SNARE complex, partially inhibiting acetylcholine release at the neuromuscular junction, reducing repeated facial muscle contractions that cause dynamic wrinkles. Applied topically, it does not cross to the dermis at meaningful concentrations.
At the molecular level, Argireline operates through pathways characteristic of the Cosmetic Peptide class, interacting with target receptors and downstream signaling cascades to produce its observed effects.
