Acetyl Octapeptide-1 (commonly known as SNAP-8) is an advanced anti-wrinkle octapeptide designed to target expression lines caused by muscle contractions. Derived as an elongation of the classic hexapeptide Acetyl Hexapeptide-8 (Argireline), it offers enhanced efficacy in relaxing facial tension and smoothing fine lines.

Mechanism of Action

Acetyl Octapeptide-1 mimics the N-terminal end of SNAP-25, competing with natural SNAP-25 for a position in the SNARE (SNARE complex) assembly.

• SNARE Inhibition: By destabilizing the formation of the SNARE complex, it inhibits the calcium-dependent release of neurotransmitters (acetylcholine) at the neuromuscular junction.
• Muscle Relaxation: Reduced neurotransmitter signaling leads to attenuated facial muscle contractions.
• Line Smoothing: Softens expression lines around the forehead, crow's feet, and nasolabial folds without paralyzing the facial muscles.

Key Benefits & Clinical Performance

• Enhanced Anti-Wrinkle Efficacy: Outperforms standard hexapeptides in reducing the depth and density of dynamic wrinkles.
• Targeted Action: Highly effective on high-motion areas (orbitals, forehead, glabella).
• Synergistic Potential: Works exceptionally well in combination with hydrating actives (e.g., Hyaluronic Acid) and matrix-rebuilding peptides (e.g., Palmitoyl Pentapeptide-4).

Formulation & Handling Guidelines

• Recommended Dosage:
  • Powder form: 0.005% – 0.05%
  • Liquid solution (0.05% peptide content): 3.0% – 10.0%
• pH Range: 3.0 – 6.0 (Optimal formulation stability around pH 4.5 – 5.5)
• Incorporation: Add during the cooling phase of production (T<40℃). Avoid prolonged exposure to high temperatures or strong acids/bases to prevent peptide degradation.
• Incompatibilities: Strong oxidizing agents, heavy metal salts, and highly alkaline conditions.
