Leuphasyl Research Guide

Full name: Leuphasyl (Pentapeptide-18)

A pentapeptide mimicking enkephalin that binds enkephalin receptors on nerve cells, reducing neural excitability and complementing argireline for enhanced anti-wrinkle effects.

How Leuphasyl Works

Binds enkephalin receptors on neuronal membranes, reducing calcium influx and neurotransmitter release at the presynaptic level. Works upstream of argireline.

Dosing Protocol

• Typical dose: 3-5% solution
• Frequency: 2x daily
• Duration: 4-8 weeks
• Route: Topical

Reported Benefits

• Complements argireline action
• Reduces muscle tension
• Smooths expression lines
• Gentle mechanism

Potential Side Effects

• Minimal side effects
• Rare tingling

Research Citations

1. Synergistic anti-wrinkle effects of leuphasyl and argireline (2020) - 5% leuphasyl + 10% argireline reduced wrinkle depth by 47% vs 30% for argireline alone.
2. Enkephalin-mimetic peptides for cosmetic neuromodulation (2019) - Reduced nerve cell excitability by 35% through enkephalin receptor binding.
