How is Argireline different from Botox?

Both target SNARE-mediated neurotransmitter release, but Argireline is a topical peptide with a milder, reversible effect, whereas botulinum toxin is injected and far more potent.

Is Argireline the same as Acetyl Hexapeptide-8?

Yes. Argireline is the trade name and the INCI naming has been updated to Acetyl Hexapeptide-8, referring to the same six-amino-acid peptide.

Acetyl Hexapeptide-3 (Argireline)

Also known as: Argireline, Acetyl Hexapeptide-3, Acetyl Hexapeptide-8

Argireline is a topical cosmetic peptide marketed as a needle-free alternative to neuromodulators, used to soften the appearance of expression lines.

Mechanism of Action

Acetyl Hexapeptide-3 is a fragment that mimics the N-terminal end of SNAP-25, a component of the SNARE complex required for neurotransmitter vesicle docking and fusion. By competing with native SNAP-25 for assembly into the SNARE complex, it partially destabilizes the complex and reduces catecholamine and acetylcholine release at the neuromuscular junction. This attenuates the muscle contractions that drive dynamic expression lines, producing a mild, reversible softening of fine wrinkles when applied topically.
