If you’re looking to grow your lashes but aren’t ready to commit to extensions or falsies, a lash growth serum might be just what you need. And while it might seem like a modern-day miracle, the idea of lash-enhancing formulas actually started as a side effect.
“Patients using glaucoma drops began noticing their lashes were growing longer and fuller,” explains ophthalmologist Dr. Ashley Brissette. The active ingredient behind the growth? Bimatoprost—a prostaglandin analogue—later repurposed into the FDA-approved lash treatment, Latisse.
While effective, these ingredients come with risks like irritation, iris discoloration, and fat loss around the eyes. That’s why many new formulas are turning to gentler, prostaglandin-free ingredients like peptides and biotin, offering natural enhancement without the side effects.
We tested and reviewed dozens of lash serums, and these 10 rose to the top—each one recommended by eye doctors and loved by users.
