This Eyelash Serum Is Sold Every 30 Seconds and Was Developed by an Ophthalmologist—Here’s Why We Love It

If you want to fake the appearance of longer, thicker lashes, there’s an entire Internet of options on the market to help you do it. You can coat ’em in mascara, slap on a pair of falsies, or go all-in on extensions. But if you want to amp them up for real (without spending your entire paycheck at the lash bar or having to learn how to apply fake eyelashes), your best bet is Revitalash Advanced Eyelash Conditioner and Serum ($150).

I was first introduced to the serum by a friend who used it every day for the six months leading up to her wedding. I cornered her at the rehearsal dinner, demanded to know who did her eyelashes, and was shocked to learn that the epic growth was a result of using Revitalash. Reviewers have called it the “best lash product ever” and confirm that it “definitely works,” and I can tell you firsthand that they are absolutely right.

The ingredients list is stacked with a combination of biopeptin complex, peptides, and botanicals, which work together to saturate the lashes in order to keep them soft and prevent brittleness and breakage. It’s a conditioner and a serum in a single formula (most lash products are either one or the other), and it delivers both benefits in a single swipe.

According to Joshua Zeichner, MD, a board-certified dermatologist based in New York City, using a product like Revitalash is critical for keeping your natural lashes looking long, luxurious, and healthy. “Our eyelashes help protect our eyes from dirt in the air, and applying and removing makeup can dry out lashes leading to breakage, and it can even lead to lashes falling out in extreme cases,” he says. “A lash conditioner will keep your natural lashes moisturized and give them the nutrients they need,” Amanda Robinson, founder of Los Angeles-based eyelash extension company Iris+West, previously told Well+Good. “A serum, on the other hand, is more likely to have ingredients such as peptides and amino acids that can actually help new lashes grow, lengthen, and add density to your natural lash line.”

The formula has an ophthalmologist’s stamp of approval, and has been reviewed by dermatologists and clinically tested to confirm that it’s hypoallergenic and non-irritating. The one thing you’ll want to watch out for, though, is that it may cause some discoloration on the skin around your eyes, and if that happens it’s a sign that it’s time to stop using. Swipe it on every night before bed, then get ready to tell everyone how your lashes got so long.
