SNAP-8

Acetyl Octapeptide-3, a topical peptide studied for smoothing expression lines with a “Botox-like” mechanism.

SNAP-8 (Acetyl Octapeptide-3) is a topical cosmetic peptide studied for reducing expression lines by competing in the SNARE complex to limit acetylcholine release. Topical clinical studies with measured wrinkle-depth endpoints support its cosmetic use.

Why BLP features SNAP-8

Included because it has topical clinical studies with objectively measured wrinkle-reduction endpoints and a clear cosmetic mechanism. Its measured outcomes and growing use place it among the better-supported cosmetic peptides, though it remains a topical cosmetic research ingredient.

Mechanism

Competes with SNAP-25 in the SNARE complex to limit acetylcholine release.

Relaxes facial muscles responsible for dynamic wrinkles.

Reduces expression-line depth over time with consistent topical use, without paralysis.

WHAT THE RESEARCH MEASURED

Research findings

Findings describe study outcomes, not expected personal results.

Human research findings

Clinical studies with 10% formulations reported wrinkle-depth reduction up to roughly 63% around the eyes over 28 days.
Reported average reductions of 30–35% in forehead and crow's-feet expression lines.
Reported improved skin smoothness, elasticity, and texture.
Effects build with twice-daily application, often noticeable in 4–8 weeks. Mostly well tolerated; rare mild tingling or redness.

Mechanistic & supporting research

SNARE-complex mechanism characterized in cosmetic-science research.
Wrinkle-reduction endpoints measured in topical formulation studies.

Regulatory status

SNAP-8 is a topical cosmetic research ingredient and is not an FDA-approved drug. Sold and offered strictly for laboratory and research use.
