Snap-8 (Acetyl Octapeptide-3) (SNAP8) is a anti-aging peptide, at the cosmetic use stage in the published literature. Snap-8 (Acetyl Octapeptide-3) is a synthetic peptide developed by Lipotec as a milder, topical alternative to botulinum toxin for reducing facial wrinkles. It is an elongated version of Argireline (Acetyl Hexapeptide-3), with two additional amino acids providing enhanced stability and efficacy. The peptide works by interfering with the SNARE complex formation needed for neurotransmitter release at neuromuscular junctions, effectively reducing the intensity of facial muscle contractions that lead to expression lines. Multiple clinical studies have demonstrated a measurable reduction in wrinkle depth after 28 days of topical application. Snap-8 is widely used in the cosmeceutical industry and is found in many premium anti-aging skincare products.

Snap-8 competes with SNAP-25 for a position in the SNARE complex, which is essential for neurotransmitter release at neuromuscular junctions. By destabilizing the SNARE complex, it reduces acetylcholine release and diminishes excessive facial muscle contractions that cause expression lines.
