Argireline
Also known as: Acetyl Hexapeptide-3, Acetyl Hexapeptide-8, AH3
Argireline is the most widely researched topical 'Botox-alternative' cosmetic peptide, an acetylated hexapeptide that inhibits neuromuscular transmission to relax facial muscles and reduce dynamic wrinkle depth by 17–27% in clinical studies.

Key Benefits
- Reduces depth of dynamic expression wrinkles 17–27%
- Non-invasive topical Botox alternative
- Smooths forehead, eye area, nasolabial fold lines
- Widely studied — published clinical efficacy data
- Synergistic with SNAP-8 for enhanced effect
- Reduces fine lines around eyes (crow's feet)
- Improves skin smoothness and texture
- Well tolerated across all skin types
Mechanism of Action
Argireline (Acetyl-Glu-Glu-Met-Gln-Arg-Arg-NH2) is a fragment of SNAP-25, a SNARE complex protein required for neurotransmitter vesicle docking. Argireline competitively inhibits formation of the SNARE complex at neuromuscular junctions, reducing acetylcholine release and thus muscle contraction intensity. The result is partial relaxation of facial expression muscles without paralysis — a mechanism similar to Botox but topically delivered at lower efficacy. Optimal concentrations are 5–10%; higher concentrations may cause temporary ptosis.
Dosing Protocols
Anti-Wrinkle Serum
- Dose
- 5–10% concentration
- Frequency
- Twice daily
- Timing
- AM after cleansing / PM before bed
- Cycle
- Ongoing; visible results in 28–56 days
Avoid >10% — can cause temporary muscle droop. Combine with SNAP-8 at 3–5% for synergy
Eye Cream / Crow's Feet
- Dose
- 5–8% concentration
- Frequency
- 1–2x daily
- Timing
- Around eye area, tap gently
- Cycle
- Ongoing
Allow to dry before applying moisturizer on top

Side Effects
- Generally very well tolerated
- At >10%: temporary eyelid/brow ptosis (drooping)
- Rare: mild redness in sensitive skin
- No systemic absorption at cosmetic doses
Contraindications
External use only. Not for injection. Keep below 10% concentration. Avoid eye contact. Not studied in pregnancy (no known risk but insufficient data).
Storage
Active ingredient: 2–8°C. Formulated products: cool, dry place per product label. Typically stable for 24 months.
