Argireline
Argireline (Acetyl Hexapeptide-3/8)
One of the most widely used cosmetic peptides, Argireline reduces expression lines by inhibiting neurotransmitter release at neuromuscular junctions.
Mechanism of Action
Argireline is a fragment of SNAP-25 that competes with the full protein for inclusion in the SNARE complex. By partially blocking SNARE complex formation, it reduces acetylcholine release, relaxing facial muscles.
