QUALASH vs. The Ordinary: which peptide lash serum is right for you?

Where QUALASH wins
Read our full QUALASH Activating Peptide Eyelash Serum review too.
The difference is in how the formula is built. QUALASH chooses three peptides that each tackle a different part of the process: Acetyl Tetrapeptide-3 for anchoring the lash, Octapeptide-2 for the growth phase and Biotinoyl Tripeptide-1 for strength and thickness. It's a targeted combination developed purely for lashes — and the reason the serum earns the highest peptide score in our ranking. If you want the most complete peptide profile and are happy to spend a little more, choose QUALASH.
Where The Ordinary wins
The Ordinary is the value champion. You get four named peptides — including the well-known Myristoyl Pentapeptide-17 — for a fraction of the cost of premium serums, and the same bottle works on your brows. On the other hand, the formula has fewer conditioning extras and results tend to build more slowly. If you're new to serums or want to check you can stick with a nightly routine first, The Ordinary is a logical first step. More budget options in the best lash serum under $20.
What they have in common
Both serums are peptide formulas without a prostaglandin analog, so both work gradually. With either, expect 4 to 8 weeks for the first visible change and around 12 weeks for the full result. Apply every evening to a clean, dry lash line — one stroke is enough — and let it dry before applying eye cream.
Our verdict
Choose QUALASH if you want the strongest, most targeted peptide profile on sale in 2027, purely for your lashes. Choose The Ordinary if price is the deciding factor or you want one serum for lashes and brows. To see the other six peptide serums — from SWEED to Clinique — head to the full Top 8.
