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
No-frills skincare brand The Ordinary just released their lash and brow serum over the summer, and it already has over 180,000 likes on Sephora. I've personally been using this serum for a little under two months now as a more wallet-friendly option, and so far I'm pleased with the results. My lashes have already started to lengthen, so I'm excited to see the difference a full three months will make. This lightweight serum is packed with peptides for fuller and healthier lashes and brows. And at just $15, this serum is a great option for those on a budget.
Pros: Under $15; Prostaglandin-free (more on this ingredient below); Can be used on lashes and brows; Contains peptides associated with hair growth (acetyl tetrapeptide and biotinoyl tripeptide)
Cons: Contains four preservatives (Sodium benzoate, Benzoic acid, Ethylhexylglycerin, Phenoxyethanol and Clorphenasin) that "can be damaging to the meibomian glands and the ocular surface, exacerbating a dry eye," notes Dr. Hilal-Campo; Chlorphenasin may cause swelling, redness, and irritation
The Revitalash serum is a cult favorite and for good reason. "Their Biopeptan Complex has a blend of biotin, lipids, and tea tree oil to help with lash growth," says Dr. Saedi. Not only will your lashes reach new heights, but this serum also acts as a conditioner to prevent breakage and to keep lashes strong, moisturized, and shiny. With its blend of vitamins and nutrients, your lashes may develop a natural curl, too. Dr. Saedi adds, "The company has also done extensive testing to demonstrate its results," which is a huge plus. If your eyes are prone to irritation, the brand just released a new formula for sensitive eyes (opens in new tab).
Pros: Conditions lashes; Vegan formula; Protects against breakage
Cons: Contains a type of prostaglandin; Over $60 for a full-size tube
This clinically tested product is chock-full of lash-loving ingredients. Key ingredients include keratin, biotin, plant-based stem cells, and pumpkin-seed extract to help grow your lashes to falsies-length. "With Borboleta Lash Serum, we’ve been blown away by the feedback from our lash fam," says Borboleta founder, Kim Jaynes. But as with any beauty product, Jaynes warns that consistency really is key when it comes to lash serum. With that being said, reviewers note that they start to see results in as little as four weeks.
Pros: Fast-acting; Safe with lash extensions; Conditioning formula
Cons: Contains a type of prostaglandin; Over $60 for a three-month supply
If environmentally friendly beauty is important to you, look no further than Luna Nectar's Lash Serum. This serum is completely vegan and all-natural, so Dr. Hilal-Campo counts herself as a fan. "I like that this serum uses entirely natural ingredients to promote lash growth and condition lashes, like castor oil and sweet almond oil," she says. The formula is water-free, meaning active ingredients are extra potent, resulting in faster results. The waterless formula also means that it doesn't contain preservatives, so it's gentle on the eyes.
Pros: Vegan and all-natural formula; Free of prostaglandin and preservatives; Can be used on lashes and brows
Cons: Over $60; Dr. Hilal-Campo noted the high number of ingredients, adding "the more ingredients in a product, the more the likelihood of having an allergic reaction to one of them;"
For many women, long and thick lashes evade them because the lashes aren't getting the nutrients they need. With RapidLash, each eyelash is given strengthening and conditioning ingredients that allow consumers to finally see the results they want. Strengthening and nourishing ingredients include polypeptides, biotin, panthenol, amino acids, soybean oil, and vitamin-rich pumpkin seed extract. With this ingredient-packed serum, lashes become fuller, stronger, and thicker in as little as eight weeks.
Pros: Strengthening and conditioning formula; Safe with eyelash extensions
Cons: Contains a type of prostaglandin; Reviewers say it's thick and hard to apply
There's a reason this cruelty-free serum has thousands of five-star reviews across the internet. It's jam-packed with vitamins, antioxidants, and amino acids built to tackle the brittlest of lashes. I can personally attest that this serum means business. My lashes grew dramatically in just three months with consistent use, making lash serums a staple in my skincare routine. Even Dr. Saedi is a fan of this cult-favorite serum. "Grande is my go-to for fuller, thicker lashes and brows," she says. "I’ve used GrandeLASH-MD for years, ever since my eyelashes thinned after pregnancy, and have seen amazing, noticeable, lasting result."
Pros: Contains vitamins, antioxidants, and amino acids; Hydrates lashes with hyaluronic acid
Cons: Contains a type of prostaglandin; Over $60 for full-size tube
Clean beauty is all the rage these days, and after using this all-natural formula, you'll see why. LashFOOD Phyto‐Medic Eyelash Enhancer uses a blend of medicinal herb extracts, soy protein, and arginine to nourish and grow lashes. With ingredients you'll actually recognize, this formula is 99 percent natural and is even Ecocert certified. With no preservatives or prostaglandins, you won't have to worry about irritation or longtime side effects. Reviewers note that the longer you use this product, the better the results.
Pros: All-natural formula; Free of preservatives and prostaglandins; Strengthens lashes
Cons: Over $60; May take longer to see results
If you're worried about potential side effects with eyelash growth serums, put your mind at ease with this ophthalmologist-developed (and tested!) product. Created by Dr. Hilal-Campo, she explains "it uses a blend of plant oils, including castor oil, to promote lashes that are naturally thicker, longer, and healthier. It also doubles as a treatment to soothe dry eyes. It does not contain any preservatives, which are also irritating to the eyes and can cause damage to the ocular surface."
Pros: Developed and tested by ophthalmologists; Free of prostaglandin and preservatives; All-natural and vegan formula; Can be used on lashes and brows; Under $60
Cons: Does not come with brush
The reviews don't lie when it comes to this serum—over 19,000 Amazon users swear by this inexpensive product and gave it 5 stars. This favorite serum contains biotin, castor oil, and peptides to create long, healthy lush lashes over time. Each ingredient is clinically tested and hypoallergenic, two major wins when it comes to eyelash growth serums. If the reviews aren't enough to convince you of this lash-boosting formula, the before-and-after pictures speak for themselves.
Pros: Under $60; Can be used on brows and lashes; Contains peptides to strengthen lashes
Cons: May take longer to see results
Who doesn't love a 2-in-1 product? This lash serum features a dual formula for night and day, so your lashes will always be nourished. Use the wand side as a primer before mascara for a long-lasting look alongside promoted growth. Then at bedtime, use the brush side to grow lush lashes overnight. Both formulas use a blend of Red clover extract, biotin, keratin, silk amino acids, vitamin B5, and hydrating fruit sugars to achieve the best lashes of your life.
Pros: Acts as a primer and serum; Contains peptides associated with hair growth (acetyl tetrapeptide and biotinoyl tripeptide); Prostaglandin-free
Cons: May take longer to see results
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!
