Argireline (Acetyl Hexapeptide-8)

aka acetyl hexapeptide-8 · acetyl hexapeptide-3 · ahp-8

The 'topical Botox' marketing molecule — a SNAP-25-mimicking hexapeptide that modulates neurotransmitter release in muscle-fiber expression-line areas. Real but modest clinical effect (5–17% wrinkle-depth reduction in 30-day trials at 5–10%); the 2025 conversation is honesty about the gap between marketing ('Botox in a jar') and biology (mild, cumulative softening of dynamic lines). The Ordinary, The Inkey List, and prestige peptide blends carry it.

Benefits
  • modest reduction in expression-line depth with sustained use
  • well-tolerated, no irritation or photosensitivity
  • stacks with other peptide families for combinatorial benefit
Example uses
  • expression-line serums
  • peptide complexes
  • lip and eye treatments
Formulation notes

Effective at 5–10% in serums; lower doses are cosmetic theater. pH 5–7. Pairs with copper peptides, signal peptides (Matrixyl), and HA. Penetration to neuromuscular junction depth is debated — most efficacy is likely upper-dermal signaling.

Watchouts

Real effect is modest. 'Topical Botox' claims overstate. Not a substitute for actual neuromodulator injection in expression-line treatment.
