Argireline (Acetyl Hexapeptide-3)

Skin, Hair & Aesthetics
Phase 3

Argireline is a synthetic six-amino-acid peptide widely used in cosmetic skincare as a topical alternative to botulinum toxin injections. It works by partially blocking the nerve signaling pathway involved in muscle contractions, reducing the intensity of facial movements and softening expression lines around the eyes and forehead.

Overview of Argireline (Acetyl Hexapeptide-3)

Inhibits SNARE complex assembly to reduce acetylcholine release at neuromuscular junctions, relaxing facial muscles and reducing the appearance of dynamic wrinkles.

Skin / cosmetic

Mimics the N-terminal of SNAP-25, one of the three proteins in the SNARE complex required for synaptic vesicle fusion and neurotransmitter release.

Competes with native SNAP-25 for binding in the SNARE complex, destabilizing the complex and reducing vesicle docking efficiency.

Decreases acetylcholine release at the neuromuscular junction, reducing the intensity of facial muscle contractions that cause expression lines.

Wrinkle reduction

Targets dynamic wrinkles — lines formed by repeated facial expressions (forehead lines, crow's feet, frown lines).

Clinical studies report up to 30% reduction in wrinkle depth after 30 days of twice-daily topical application at 10% concentration.

Topical delivery

Applied topically in serums and creams as a non-invasive alternative to neurotoxin injections.

The acetyl group improves skin penetration compared to the unmodified hexapeptide.
