The ingredient narratives reshaping clean beauty.
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.
- modest reduction in expression-line depth with sustained use
- well-tolerated, no irritation or photosensitivity
- stacks with other peptide families for combinatorial benefit
- expression-line serums
- peptide complexes
- lip and eye treatments
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.
Real effect is modest. 'Topical Botox' claims overstate. Not a substitute for actual neuromodulator injection in expression-line treatment.
Trusted as a clean-credentialed synthetic peptide.
