At a Glance

Snap-8 (acetyl octapeptide-3) is a cosmetic peptide used in topical skincare products. Evidence and tolerability are formulation-specific, and many studies evaluate multi-ingredient products rather than isolated acetyl octapeptide-3.

⚠️ Educational Only: This page summarizes cosmetic research and intentionally does not include protocols/dosing.


Mechanism of Action (TBD)

Often described as “Argireline-like” in cosmetic framing; mechanistic claims should be validated against primary sources for a given formulation.


Evidence Summary

Microneedle patch study (multi-ingredient)

Low Confidence Observational ≤3 Years

A monocentric clinical study of hyaluronic-acid microneedle patches containing multiple bioactives (including acetyl octapeptide-3) reported improvements in measured skin properties and good tolerability; attribution to a single ingredient is not possible. [PMID: 31134751]


Safety & Unknowns

  • Topical tolerability varies by formulation and individual sensitivity.
  • Multi-ingredient formulations limit causal attribution to acetyl octapeptide-3 alone.
