As someone who may have the world’s shortest eyelashes—ones that fall out with every nightly wash of my face—I dream of the kind of thick, fluttery lashes that seemingly only models and celebs are blessed enough to have. Sure, the best mascaras out there promise sky-high, voluminous lashes in a few swipes, but the effect is only temporary, and sometimes—well, actually, all the time—your lashes are begging for some TLC.

Eyelash extensions, false and magnetic eyelashes, makeup removers, and even some mascaras can all weaken lashes over time. Thankfully, because we live in the 21st century, the beauty gods have blessed us with a kind of technology only money can buy: eyelash serums. The best eyelash serums will take your lashes from short and stubby to long and luscious in a matter of a few weeks. I myself have had some impressive results with two serums—GrandeLASH-MD (opens in new tab) and The Ordinary Multi-Peptide Lash and Brow Serum (opens in new tab) (more on these products down below). After a few months of consistent use, my lashes are long enough that I can confidently step out with just a swipe of mascara.

But if you’re skeptical of the magic of lash serums, we’ve consulted lash experts—Dr. Nazanin Saedi and Dr. Diane Hilal-Campo—to get the lowdown on everything you need to know. Read on to shop our favorite lash-growing serums and hear from the pros on the ingredients to look for, safety concerns, and how to achieve the results of your dreams.  

The Best Eyelash Growth Serums

How Do Eyelash Growth Serums Works?

Eyelash serums have become a tried-and-true method for many seeking a doll-eyed look and their miraculous results all come down to the serum’s lash-boosting ingredients. Board-certified dermatologist, Dr. Nazanin Saedi, MD, explains that these serums contain “peptides, biotin, keratin, oil, and other natural and active ingredients.” With these ingredients, lash serums “work by supporting and strengthening the hair follicles within your lash line and stimulating and extending the growth cycle.” 

When it comes to eyelash serums and their ingredients, you can also decide to go the all-natural route, which also comes derm-recommended. “I highly recommend only looking for growth serums that use natural ingredients to promote longer lashes,” says Dr. Diane Hilal-Campo, board-certified ophthalmologist and founder of twenty/twenty beauty. “These ingredients include castor oil, which features fatty acid ricinoleic acid to help grow lashes, and nutrients like selenium and biotin, which support healthy hair growth.” 

Are Eyelash Growth Serums Safe?

No, not all eyelash growth serums are safe. In fact, Dr. Hilal-Campo says there are “very few” serums she actually recommends her patients use, and it all boils down to one specific ingredient commonly found in serums—Prostaglandin analogues. Prostaglandins are fatty lipids naturally found in the body, whereas prostaglandin analogues are lab-made and used in serums to prolong the growth phase of the lash growth cycle. “While they do effectively stimulate lash growth, they come with lots of risks and side effects,” says Dr. Hilal-Campo. 

Side effects include fat atrophy around the eyes, discolored eyelid skin, pigment changes of the iris, red, dry eyes, cystoid macular edema, and iris cysts. To see if an eyelash growth serum contains prostaglandin analogues look out for bimatoprost, isopropyl cloprostenate, and dechloro-dihydroxy-difluoro ethylcloprostenolamide in the ingredient list. Dr. Hilal-Campo does not recommend any eyelash growth serums that contain prostaglandin analogues as they could cause permanent harm to the eye.

It’s also important to note that Latisse, aka bimatoprost, is the only FDA-approved eyelash growth serum and you do need a prescription from your doctor for it. Dr. Hilal-Campo explains that Latisse was originally approved as a glaucoma eyedrop treatment and eye doctors are aware that eyelash growth is a side effect of the medication, as well as the side effects mentioned above. “When you're at risk of losing vision with glaucoma, which is a blinding eye disease, these side effects are worth it. They are not if you solely want longer lashes,” says Dr. Hilal-Campo. 

She warns that cosmetic companies have made their own versions of Latisse that are not regulated, do not come with side effects disclosed, and may even be stronger than the prescription strength Latisse, causing greater side effects. All in all, it’s important to research the ingredients of an eyelash growth serum before purchasing, and if you start to experience any side effects or irritation, stop using the serum immediately

How Long Before You See Results From Eyelash Growth Serums?

I’m sure you’ve heard the saying “consistency is key” when it comes to diet and exercise, but the phrase also applies to your lashes. “As with any hair growth journey, you need to be committed and consistent,” says Dr. Saedi. She recommends adding your lash serum to your daily skincare routine and if you stick with it, you should start to see fuller, thicker lashes in about three months. 

Of course, pay attention to the serum’s application instructions, as this could affect your results. Some serums are only applied once a day, while others are applied in the morning and evening. Don’t make the mistake of impeding your results by not bothering to read the instructions!
