Research Overview
Pentapeptide-18 (Leuphasyl) is a synthetic pentapeptide that mimics enkephalin to reduce catecholamine release at the neuromuscular junction. This produces muscle relaxation through a different pathway than Argireline (SNARE) or Syn-AKE (nicotinic receptor), making it a complementary anti-wrinkle peptide.
Key Research Findings
- •Enkephalin-mimetic mechanism — reduces catecholamine release for muscle relaxation
- •Complementary anti-wrinkle mechanism to Argireline and Syn-AKE
- •Can be combined with other muscle-relaxing peptides for synergistic effect
- •Targets a different neuromuscular pathway than other wrinkle-relaxing peptides
Research Dosage Protocols
Applied topically at 3-8% concentration in anti-wrinkle formulations.

Frequently Asked Questions
What is Pentapeptide-18?
Pentapeptide-18 (Leuphasyl) reduces wrinkles through an enkephalin-mimetic mechanism, relaxing facial muscles via reduced catecholamine release — a different pathway than Argireline or Syn-AKE.
