Does The Ordinary Lash Serum Work? Ingredients and Results
It is one of the most affordable lash serums on the market, but does The Ordinary lash serum actually work? We review the peptides and the expected results.

For years, the gold standard for eyelash growth was prescription Latisse (bimatoprost). While highly effective, prostaglandin analogs carry risks like orbital fat loss and permanent changes to eye color. The beauty industry has responded with peptide-based alternatives, most notably The Ordinary's highly affordable Multi-Peptide Lash and Brow Serum. But without those aggressive medical ingredients, does The Ordinary lash serum work?
How it Works: The Power of Peptides
The Ordinary's serum relies entirely on a complex blend of 11 active peptides (including Myristoyl Pentapeptide-17 and Biotinoyl Tripeptide-1). Peptides are essentially fragments of proteins. When applied to the lash line, they act as messengers, signaling the hair follicles to produce more keratin (the protein that makes up hair).
Instead of artificially forcing the lash into a prolonged growth phase like a prostaglandin does, these peptides nourish the follicle, creating an optimal environment for the lash to grow to its maximum natural potential before shedding.
The Results You Can Expect
If you are expecting the dramatic, spider-lash effect of Latisse, you will be disappointed. However, clinical studies and thousands of reviews show that The Ordinary's serum absolutely works for its intended purpose:
- Density: Lashes appear significantly thicker and denser at the root.
- Health: The serum acts as a heavy-duty conditioner, preventing premature breakage so your lashes naturally reach a slightly longer length.
- Timeline: Because it is non-hormonal, it takes longer. You must use it twice daily for a minimum of 8 weeks to see visible results.
The Safety Advantage
The biggest selling point of this serum isn't just the price; it's the safety profile. Because it is free of prostaglandins, it has a 0% chance of causing iris darkening, sunken eyes (orbital fat loss), or severe irritation. It is safe for pregnant women, those with sensitive eyes, and contact lens wearers.
Summary
Does The Ordinary lash serum work? Yes, it is a highly effective, scientifically sound conditioning treatment that uses peptides to maximize the thickness and natural length of your lashes. It will not give you artificial-looking length, but it is one of the safest and most affordable ways to achieve naturally healthier lashes.
