SNAP-8: cosmetic wrinkle claims and the actual test formula
How does it work?
SNAP-8 is the cosmetic name for acetyl octapeptide-3. The maker proposes that it interferes with SNARE-complex formation, a step involved in neurotransmitter release. Cell assays support biochemical activity, but do not show that a topical cream acts like injected botulinum toxin in facial muscles. [1]
What do studies show?
The manufacturer’s technical sheet describes a 28-day skin-topography test in 17 women using a cream with 10% of its SNAP-8 solution twice daily. The supplied solution contained 0.05% active ingredient, so “10%” is not 10% pure peptide in a cream. The sheet reports a maximum wrinkle-depth reduction, but provides limited independent trial detail and no randomized comparison. It is preliminary cosmetic evidence, not a proven therapeutic effect. [1]
Safety
Topical cosmetic use and injection are different exposure routes. This supplier’s 20 mg research vial is not the tested finished cream; no injection efficacy or safety can be inferred from the manufacturer sheet.

EVIDENCE CONTEXT
Why?
The cited evidence does not establish a dose for this use or product.
The manufacturer describes 3–10% of its diluted SNAP-8 solution in a topical formula; the small volunteer test used 10% of that solution twice daily for 28 days. Those are product-formulation percentages, not an amount of pure peptide to inject. No safe or effective injectable dose has been established. [1]
