SNAP-8 (Acetyl Octapeptide-3) is a synthetic octapeptide derived from the N-terminal region of SNAP-25, a core protein of the SNARE complex that governs vesicle-mediated neurotransmitter release. It is a two-residue extension of Acetyl Hexapeptide-8 (Argireline) and is studied as a competitive, reversible modulator of SNARE complex assembly — mechanistically distinct from agents that cleave SNAP-25 irreversibly. Best known as a topical cosmetic ingredient, it remains a standard reference peptide in expression-line and dermal formulation research.

BENEFITS/SNAP 8 Peptide

• Expression-line research — studied for effects on dynamic wrinkle depth in topical models

• SNARE-complex modulation — competes with SNAP-25 during vesicle docking assembly

• Reversible mechanism — competitive occupancy rather than proteolytic cleavage

• Topical formulation — water-soluble and stable across common cosmetic research bases

• Argireline comparison — the standard side-by-side reference for Acetyl Hexapeptide-8

WHAT RESEARCHERS LOOK AT

• Wrinkle-depth and periorbital line measurement across 28-day protocols

• SNARE complex assembly and presynaptic vesicle docking kinetics

• Catecholamine and neurotransmitter release in cell-based assays

• Comparative potency versus Acetyl Hexapeptide-8 (Argireline)

• Percutaneous penetration and peptide stability in topical carrier systems
