About Leuphasyl
- What it is
- Leuphasyl is the trade name for pentapeptide-18, a synthetic peptide related to the natural opioid peptide leu-enkephalin. It is used in topical cosmetic products, sometimes alongside other peptides, and is marketed to soften the appearance of expression lines. Its cosmetic activity is supported mainly by manufacturer and laboratory data. It is regulated as a cosmetic ingredient.
- How it works
- It acts as an enkephalin-like ligand at neuronal receptors and is proposed to modulate the signaling that drives muscle contraction.

Disclosure. Some vendors above are Peptul partners and pay us a commission when you buy through our link. Rows are ordered by: Peptul partners first, then what is in stock, then single vials before multi-vial packs, then price per milligram. Paying us moves a vendor up this order and changes nothing else - not their trust tier, COA badge, Peptul Score or reviews, which come from evidence and are worked out the same way for everyone. Available discount codes are shown beside the prices above. Discounted prices require the displayed code where indicated.
