Acetyl Hexapeptide-8: does it work, and at what %?
Acetyl Hexapeptide-8 is one of the actives we grade on evidence, not marketing. The benefit is real — but only when the dose clears the threshold the research supports. Here's the number, and the products that actually hit it.
The verdict: A study using a 10% acetyl hexapeptide-8 oil-in-water emulsion reported up to a 30% reduction in expression-line wrinkle depth after 30 days, though no double-blind anti-wrinkle trials are available.
How we grade Acetyl Hexapeptide-8
We check the disclosed concentration against the effective threshold from peer-reviewed dermatology literature and regulatory monographs, then weigh the formulation and any product-specific study. The grade is computed from the open rubric — re-run it on any ingredient list and you get the same letter. Also labeled as Argireline, Acetyl Hexapeptide-3, Ac-EEMQRR.

Common questions
What concentration of Acetyl Hexapeptide-8 is effective?
On Visage Theory's rubric, Acetyl Hexapeptide-8 reaches an effective dose at 10% and a strong, research-backed dose at 10%. Below that, the labeled benefit is unlikely no matter how good the marketing is.
Is more Acetyl Hexapeptide-8 always better?
Not necessarily — past the effective range you mostly add irritation risk, not benefit. What matters is clearing the threshold in a stable formula, which is exactly what our grade checks.
How do I know a product actually contains an effective dose of Acetyl Hexapeptide-8?
Most brands list the active but hide the concentration. When the dose isn't disclosed we can't confirm efficacy, so we withhold a grade rather than guess. Products that disclose an effective dose are graded and listed below.
