Argireline results: what to expect and when
A topical cosmetic peptide with small, mixed wrinkle studies and limited skin penetration.
Also called: Acetyl hexapeptide-8, Acetyl hexapeptide-8 amide, Acetyl hexapeptide-3 (older name), AH8, Ac-EEMQRR-NH2.
Cosmetic peptides · SNAP-25-mimicking cosmetic hexapeptide.
A small wrinkle trial applied topical Argireline twice daily for four weeks before assessing results.
26 primary human records located, including cases and three registries without results. Small trials and mixed formulas limit confidence.
Key studies
- First wrinkle study: An early pilot found smoother wrinkles; its size limits confidence. (source)
- Cream versus gel: Both moisturizing formulas improved measurements without a placebo comparison. (source)
- Four-week wrinkle trial: A small trial found more responders than placebo. (source)
- Eyelid-spasm add-on pilot: The add-on pilot did not establish longer toxin benefit. (source)
- Higher-dose eyelid study: The tiny terminated study did not show useful symptom improvement. (source)
- Skin hydration and mechanics: The peptide changed one skin-mechanics measure; the base also moisturized. (source)
