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 and The Ordinary Multi-Peptide Lash and Brow Serum (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.
Safety and Risks of Eyelash Growth Serums
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.
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.

Best Natural Eyelash Growth Serum
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." In fact, it only has three ingredients: castor, coconut, and argan oils.
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.

Best Ingredient-Packed Eyelash Growth Serum
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.
Customer review: "This stuff works like magic. It is the only one I use because the others haven’t worked for me like this one has! I couldn’t believe the length it gave me! This product only works with consistent use. If you only do it every now and then, you will not notice a difference." — Amazon
As it would turn out, you don't have to spend hundreds of dollars to significantly improve your lashes, not when great drugstore serums like this exist. This under-$15 serum works wonders at lengthening and thickening your lashes. In fact, you'll start to see thicker, shinier, healthier-looking lashes in as little as four weeks thanks to conditioning arginine and pro-vitamin B5. The longer you use it, the more luscious your lashes will become. Apply it twice a day from roots to lashes as you would mascara, and wait for it to dry completely before applying mascara.
Pros: Conditioning; Strengthening; Free of prostaglandins; Easy to apply; Under $15.
Cons: Some note the serum leaves a residue.
Customer review: "I have not found this product to be harmful to my eyes and have been using it consistently for the past couple months. I would say it has done more for my length rather than creating a thick appearance to my lashes. It's worth the money in my opinion!" — Amazon
Best Strengthening Eyelash Growth Serum
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.
Customer review: "I LOVE this serum that does what it says it will. It makes my skimpy, see-through (really!) lashes long and thick enough that mascara makes them look WOW!! It's pricey -- but it delivers and lasts a long time. Highly recommend." — Ulta
Best Cult-Favorite Eyelash Serum
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.
Pros: Conditioning; Vegan; Protects against breakage.
Cons: Contains a type of prostaglandin; Over $60 for a full-size tube.
Customer review: "I’ve tried many eyelash serums, and Revitalash is the best. Not only do I see a huge difference in my lash length, but the application is so easy. Unlike other serums that require a new brush each time, revitalash is similar to a liquid eyeliner applicator. Super convenient." — Nordstrom

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.

Best Splurgeworthy Eyelash Growth Serum
Don't get turned away from the price tag on this pick, this serum by the celeb-loved brand Augustinus Bader produces some serious jaw-dropping results. This nourishing serum contains a powerhouse list of ingredients—biotin, to increase hair growth and strength, roselle and safflower extracts, to decrease triggers of hair loss, and red winter algae, another ingredient to promote hair growth.

Cons: Over $100; Difficult to apply.
Customer review: "It does work! Takes longer a little longer than Grandelash, but I like this one because it conditions your lashes so they don't fall out! The moment I use grandelash, my lashes always fall out." — Dermstore
Best Eyelash and Eyebrow Growth Serum
No-frills skincare brand The Ordinary recently released their lash and brow serum over the summer, and it already has over 420,000 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; 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.
Customer review: "I’ve been using this serum on my eyelashes for the last month and I am seeing results already. I was an avid eyelash extension wearer, so my natural lashes were short, brittle and I had patches that were completely gone. My lashes are full, and longer than they’ve ever been. I will 100% be buying this again." — Sephora
Best Eco-Friendly Eyelash Growth Serum
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; Dermatologist-tested.
Cons: Over $60; May take longer to see results; 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."
Customer review: "While it took me a little longer than some others to see results, they came! I loved more than anything that it’s a natural product and not like some of the other harsh chemicals (with side effects) I’ve used for quicker results. If you want growth without side effects, it’s worth the wait!" — Luna Nectar
Best 24-Hour Eyelash Growth Serum
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.
Customer review: "Most things irritate my eyes and turn them red. This does not. I actually use both ends only in the morning and nothing at night. I wait about an hour before applying any other eye makeup. I like that it conditions, separates, and lengthen each lash. I use an eyelash curler after putting it on. I rarely wear mascara, and I like this as a substitute." — Ulta
Best Vitamin-Infused Eyelash Growth Serum
In my lash journey over the years, I've been burned by quite a few lash serums. Some made my eyelashes fall out, some made my eyelids red and irritated, and others showed little to no results. I'm happy to say this lash serum does not fall into any of those categories. After about three weeks of consistent use, I've noticed my once-brittle lashes are now so much stronger and have less fall-out. I've also noticed a tiny bit of growth, so I'm excited to see what a few more months will do. The best part about this serum, though, is because it uses peptides and vitamins to stimulate growth, you don't experience any pesky side effects!
Pros: Editor-approved; Clean and vegan formula; Free of prostaglandin and preservatives; Scent-free; Hypoallergenic; Contains peptides associated with hair growth (acetyl tetrapeptide and biotinoyl tripeptide).
Cons: Over $60.
Customer review: "So far 6 weeks into using it sparingly (about once a day) my lashes are long enough to curl. Even without curling, if I add mascara, you can actually see it. That's a first for me. Additionally, I have sensitivity and this doesn't seem to bother that." — Ulta
Unfortunately for me and my sensitive eyes, not just any eyelash serum is going to work for my needs. I need something that's not formulated with any of the bad stuff (i.e. hormones, silicones, parabens, or sulfates) and that actually provides results. Enter: Vegamour's GRO Volumizing Lash Serum. Using only plant-based ingredients, this vegan serum is totally safe for sensitive eyes while still delivering impressive results. After only using this serum for a little over two weeks, I've noticed my fall-out lashes have dramatically decreased, plus my lashes are starting to look denser. I still have a ways to go before I see my full results, but I'm excited.
Pros: Editor-approved. Great for sensitive eyes; Vegan formula; Prevents fall-out.
Cons: Over $60.
Customer review: "I’ve been using this product everyday for 1 month and I can definitely see results already! My eyelashes got longer, thicker, darker, and my bottom lashes grew too! I have very sensitive eyes but I’m impressed how great is this serum! I’ve been receiving many compliments and I really believe this serum is magic. Highly recommended." — Sephora
With the wear and tear of mascara, eyelash curlers, falsies, and extensions, our natural lashes go through a lot of damage. This serum is an easy and effective way to give them some TLC. Packed with amino acids (which help build elastin and collagen) and strengthening ingredients like threonine, arginine, and serine, this serum is a surefire way to make your lashes stronger. While this serum may not give you spidery long lashes, over time your lashes will be thicker, healthier, and much stronger than ever before.
Pros: Strengthening; Conditioning; Ophthalmologist tested; Free of prostaglandins; Under $50.
Cons: Takes longer to see results.
Customer review: "I have tried several lash serums and CILS Booster Lash Serum seems to be the most effective. It works toward thickness not so much lengthening of my eyelashes." — Nordstrom
If you're a beauty fan, I'm willing to bet you already know OLAPLEX for their viral bond-building hair products. If so, then it should come as no surprise that their lash serum is just as good. The formula contains the very same bond-building technology found in their haircare to restore damaged lashes from within. It's also chalk full of peptides to support the look of fuller, thicker lashes, plus hyaluronic acid and biotin to hydrate dry, brittle lashes. With consistent use, you'll start to notice a difference in just two weeks.
Pros: Conditioning; Strengthening; Hydrating; Free of prostaglandins.
Cons: Over $60.
Customer review: "Yes, this is pricey. And yes, it is worth every dollar. I am in my 60s and my eyelashes were falling out, thin and barely there. I use this every day, and in one month, my eyelashes are thick, long, full, and never fall out. I have been asked if I am wearing false eyelashes a few times now. This is a miracle formula. Thank you Olaplex." — Ulta
If you have extra sensitive eyes, especially sparse lashes, or hair loss, it may be worth talking to your doctor about Latisse. Latisse, aka bimatoprost, is the only FDA-approved eyelash growth serum and it requires a prescription from your doctor. 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 below. “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.
It is clinically proven to make eyelashes longer, thicker, and darker, and I've seen firsthand the dramatic results you can achieve with Latisse. My mother, who's in her 60s, struggled with short, sparse lashes before talking to her doctor about Latisse, and now has the long, fluttery lashes of her dreams, also inspiring me to get a prescription.
For an easy and quick doctor's appointment, I recommend using Ro, an online telehealth portal. See a doctor or nurse practitioner in the comfort of your home with Ro's online visits. Online, you will detail your symptoms, health history, and goals, then one of Ro's healthcare professionals will review your information, ask any follow-up questions, then make a personalized treatment recommendation. At any time you can ask your healthcare provider questions and check their credentials through Ro's online portal. I personally used Ro for my Latisse prescription and I've never had a more easier or seamless doctor's appointment.
How Do Eyelash Growth Serums Work?
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.”
What to Look For
As you can see, there are plenty of eyelash growth serums on the market, all with different formulas. When shopping for the best serum for you, there are a few factors to consider:
- Eyelash goals
First and foremost, consider what you are hoping to achieve with an eyelash growth serum. Are you wanting spidery long lashes à la Kim Kardashian? Consider Latisse or other serums with prostaglandins, which will have a far more effective lengthening effect than serums free of prostaglandins. Maybe you're looking to strengthen and hydrate dry, brittle lashes. If that's the case, look for serums that contain strengthening ingredients such as hyaluronic acid, biotin, peptides, and amino acids.
Even if you do want long, luscious lashes, your eyes may be too sensitive to handle the potential side effects of prostaglandins (outlined above). Consider your sensitivity levels and whether you want to risk any side effects before reaching for a prostaglandin eyelash serum. Don't think you're safe from side effects just cause your serum is prostaglandin-free, either. Preservatives, parabens, hormones, and silicones, can also be irritating to sensitive eyes. If you really want to steer clear of any irritation, consider all-natural formulas such as Vegamour's Gro Volumizing Lash Serum or the LashFood PhytoMedic Eyelash Enhancer.
How to Apply Eyelash Growth Serums
While you apply most eyelash growth serums the same, it's best to read the instructions thoroughly before applying. The majority of serums work by applying a thin line on your lash line as you would eyeliner, however, other serums are applied similar to mascara through the root and tips of your lashes. Frequency differs from serum to serum as well—some you apply once a day, others you apply twice. Again, make sure to check the instructions of your serum to ensure proper application.
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!
