Argireline (Acetyl Hexapeptide-3)
Acetyl Hexapeptide-3 / Acetyl Hexapeptide-8 / Argireline
A synthetic hexapeptide that mimics the N-terminal end of SNAP-25, one of the SNARE proteins required for neuromuscular vesicle docking. By competing with native SNAP-25, Argireline reduces the release of acetylcholine at the neuromuscular junction, producing a mild 'Botox-like' effect that relaxes facial muscles and reduces expression lines. Often called 'Botox in a jar' though the effect is much milder (~30% wrinkle reduction vs Botox's near-complete paralysis).

Evidence Overview
Strength of evidence across clinical, expert, and experimental lanes.
How Argireline (Acetyl Hexapeptide-3) is dosed in practice
Usually taken on the skin. Typical range: Topical serum — typically 5–10% concentration. Half-life: N/A (topical application). Each card gives the dose, frequency and duration from one evidence lane: Clinical (human trials), Expert (practitioner protocols) or Experimental (early or animal data). These ranges describe what has been studied or used; they are not a prescription.
Work out the units to draw with the reconstitution calculator, how long a vial lasts with the vial duration calculator, and how levels fall between doses with the half-life calculator.
Wrinkle depth fell by up to 30% after 30 days with a 10% emulsion in a small 2002 study. A 2013 placebo-controlled trial of twice-daily use for 4 weeks on wrinkles around the eyes found improvement.
- Small study of a 10% emulsion (2002)
- Placebo-controlled trial (2013)
Best for prevention and maintenance between Botox appointments rather than as a standalone wrinkle treatment. Apply to clean, dry skin before moisturizer, targeting expression lines. Look for formulations with 10% Argireline. Realistic expectation: softening of fine lines, not elimination of deep wrinkles.
