Lash Peptides
Myristoyl pentapeptide-17 and acetyl tetrapeptide-3 are short chains of amino acids made for lash and brow care. The first is tagged with myristic acid, a fatty acid, so it clings to the lash line; the second is best known from brow and hair care.

Why it’s in a formula
They condition lashes and brows for a fuller, longer look over several weeks of nightly use. They are the gentle alternative to prostaglandin analogues, the drug-like ingredients in many lash serums.
- Most of the evidence for them comes from the ingredient makers’ own studies. Expect conditioning and a fuller look with steady use, not the effect of a prescription lash drug.
- Neither is a prostaglandin analogue.

Questions
What is myristoyl pentapeptide-17?
A lash-conditioning peptide: five amino acids joined to myristic acid. It is the main active in many prostaglandin-free lash serums.
How long do lash peptides take?
They are used nightly for weeks, not days. Most people judge them at six to eight weeks, and results vary from person to person.
Are lash peptides safe for sensitive eyes?
They are generally well tolerated, far more so than prostaglandin analogues. Apply to the lash line only, keep the serum out of the eye, and stop if it irritates.
