Argireline
Also known as: Acetyl Hexapeptide-3 · Acetyl Hexapeptide-8 · Leuphasyl synergist · AH3

What It Is
Argireline (Acetyl Hexapeptide-3) competitively inhibits the formation of the SNARE complex by mimicking the N-terminal (1–9) sequence of SNAP-25. By competing for binding at the SNARE complex, it reduces the stability of the ternary complex (SNAP-25/syntaxin/synaptobrevin) required for synaptic vesicle fusion and acetylcholine exocytosis at neuromuscular junctions. This partial inhibition of ACh release from motor neurons reduces muscle contraction force in facial expression muscles, smoothing dynamic wrinkles. It also inhibits catecholamine release and may have some indirect effects on extracellular matrix remodeling.

Dosing Protocols
Timing: Evening skincare routine. Apply to target areas (forehead, periorbital, glabella). Pat gently u2014 do not rub aggressively.
↓ Apply these values to the reconstitution calculatorTiming: Morning and evening. 10% twice daily showed significant wrinkle reduction in clinical studies. Apply on clean, slightly damp skin for best penetration.
↓ Apply these values to the reconstitution calculatorTiming: Morning and evening u2014 first step after cleansing. Combine with Leuphasyl (5%) and Snap-8 (5%) in the same formulation for maximum synergistic NMJ inhibition. Follow with GHK-Cu for collagen boost.

| Week | Expected Effects |
|---|---|
| Week 1 | Subtle softening of fine lines; skin feels smoother |
| Week 2 | Early wrinkle depth reduction visible in good lighting |
| Week 4 | Measurable reduction in expression line depth; forehead and crow's feet noticeably improved |
| Week 8 | Maximum effect with consistent use; wrinkles at rest visibly reduced; prevention of new line deepening |

Mechanism of Action
Argireline (Acetyl Hexapeptide-3) competitively inhibits the formation of the SNARE complex by mimicking the N-terminal (1–9) sequence of SNAP-25. By competing for binding at the SNARE complex, it reduces the stability of the ternary complex (SNAP-25/syntaxin/synaptobrevin) required for synaptic vesicle fusion and acetylcholine exocytosis at neuromuscular junctions. This partial inhibition of ACh release from motor neurons reduces muscle contraction force in facial expression muscles, smoothing dynamic wrinkles. It also inhibits catecholamine release and may have some indirect effects on extracellular matrix remodeling.

Frequently Asked Questions
Clinical studies show 10% twice daily produces the most significant wrinkle reduction (~17u201327% depth reduction in 30 days). 5% once daily shows more modest results but is a good starting point.
Yes u2014 crow's feet and periorbital lines are primary targets. The periorbital skin is thin and highly expressive, making it ideal territory for SNARE-inhibiting peptides.
No u2014 unlike Botox, Argireline requires consistent topical application over 2u20134 weeks to show measurable results as the peptide must accumulate in sufficient concentrations at the neuromuscular junction.
