Almost everyone seems to be after long, alluring eyelashes. Volumizing mascaras can only do so much and eyelash extensions can cost a fortune, but luckily, the beauty gods have blessed us with eyelash growth serums. They’re specially-formulated to give you the luscious, plentiful eyelashes of your dreams—and they really do work

Currently, there’s only one FDA-approved prescription eyelash growth serum on the market: Latisse. Packed with the hormone prostaglandin, the powerful formula is clinically proven to grow your lashes, but it requires a doctor’s prescription and comes with a lengthy list of potential side effects—including darkened eyelids and changes in your iris color (scary, right?). (Related: What I Learned from Trying Latisse to Boost Eyelash Growth)

Thankfully, there are plenty of other powerful active ingredients (like peptides and hyaluronic acid) common in non-Rx lash serums.  Most of the brands on the market rely on active ingredients that condition your lashes to fortify against breakage and moisturize your hair follicles to nourish future hair growth. (Here’s a full explainer on what’s in your eyelash serum.)

Heads up: Most eyelash serums will take at least a month to start showing full effects because your lashes are on a 30- to 45-day hair cycle. Even then, thicker lashes are never really guaranteed. However, the safe application of these over-the-counter options will, at the very least, ensure your lashes are hydrated and strengthened—which is always a win!

To help you find the right growth serum for your lashes, we scoured thousands of customer reviews across the Internet and outlined the highest-rated options out there. Made with a variety of nourishing ingredients, any of these picks will do wonders for your lash health. (Related: The Best Eyebrow Growth Serums for Healthier, Bolder Brows)

Here, the 14 best eyelash growth serums for longer, fuller lashes.

Best Overall: Pronexa Lavish Lash Eyelash and Brow Serum

The number one best-selling lash enhancer on Amazon will be the reason you finally break up with falsies. Its hypoallergenic formula combines a nourishing dose of peptides to encourage lash growth with a hydrating hyaluronic acid to nourish the hair follicle. The end result is a non-irritating serum that lengthens and strengthens with as little as two weeks of consistent use. Racking in over 29,000 five-star reviews on Amazon, happy shoppers praise the “miracle bottle” as an “affordable option” that actually works!

Best Conditioning Treatment: RevitaLash Advanced Eyelash Serum

Ophthalmologists developed this hypoallergenic formula to gently strengthen sparse, brittle lashes through a combination of growth-boosting peptides and conditioning biotin. This tiny bottle will last you three months when applied daily to your lash line—though clinical studies showed healthier-looking lashes for 98 percent of users in just six weeks. If you’re dubious about the studies, there are also plenty of rave reviews, with one user saying they experienced “really impressive results with no side effects” and another declaring “no other lash product compares.” (Related: The Anti-Aging Benefits of Peptides In Your Skin-Care Products)

Best Natural Formula: Kate Blanc Cosmetics Castor Oil

Des Moines makeup artist Ivy Boyd previously told Shape that she swears by organic castor oil as a completely all-natural (and affordable!) solution for conditioning lashes. While there’s no hard data to suggest castor oil *actually* promotes growth, it is a natural moisturizer that can nourish the hair follicle to promote longer, stronger lashes—similar to using a conditioner on your hair. Plus, this popular $10 Amazon find has more than 3,200 perfect five-star reviews and is USDA-certified organic (with the USDA’s official seal of approval). One reviewer called it their “saving grace” after eyelash extensions ruined their lashes: “So I normally don’t take the time to write reviews but for this it’s worth it. It has helped my eyelashes grow back thicker, darker and I would say a little longer than before. Highly recommend!!”

Best Budget-Friendly: EssyNaturals Eyelash Serum

There are over 4,000 perfect reviews for this budget-friendly growth serum on Amazon that’s clinically proven to boost thickness and length in just three weeks of daily use. Not to mention, users saw a 55 percent increase of natural lashes after six weeks. The star ingredient of the non-irritating formula is polygonum multiflorum, an herb prominently used in Chinese medicine to treat hair loss that’s been scientifically-proven to promote hair growth in mice. The all-natural serum can be applied to both your lashes and brows—one happy user said they’ve had amazing results with this “unbeatable” serum (they noticed a difference after a month), and it didn’t cause any eye irritation.

Best for Lash and Brow: Shiseido Full Lash Serum

You can apply this dermatologist and ophthalmologist-approved formula to both your eyelashes and eyebrows to gently hydrate hair follicles with arginine, an amino acid that can help promote hair growth and thickness. There’s enough serum in the bottle to gentle coat both your lashes and brows for one month. And though it can take up to two months to see results, rave reviews give enough reason to hold out: “This is my second tube and I am very pleased with the results. I apply 2x a day-morning and night-and have noticed a definite improvement, especially in my brows. I have very sensitive eyes and this serum doesn’t irritate at all.” (Related: 15,000 People On Amazon Are Obsessed with This Dual Lash and Brow Serum)

Best Mascara: Grande Cosmetics GrandeDrama Intense Thickening Mascara

You’ll see a noticeable volumizing boost the second you apply this mascara, but the real magic happens behind the scenes. The plant-based formula also includes a dose of VegaLash’s volumizing eyelash serum, which boosts eyelash length and retention in just 30 days through bioactive ingredients—including red clover, mung bean, curcumin, and magnolia bark. Plus, the mascara wand application means you’ll easily grab and coat every last lash. Even if you have super short lashes, one five-star reviewer writes you’ll feel like you have falsies once you see the difference in your lashes.

Best for Eyelash Extensions: LiLash Purified Eyelash Serum

You can use this cruelty-free serum with eyelash extensions because of its alcohol-free formula. (ICYDK, not only should you avoid products containing oils—since this can break the bond of your lash extensions—but alcohol can also be irritating to eyes, make lashes super brittle, and remove moisture from your lashes, which the glue needs to cure.) This serum is full of nourishing ingredients—like peptides, glycerin, and sweet almond extract (warning for those with nut allergies!)—that can actually help extensions stay on even longer. Naturally, there are tons of five-star reviews on Amazon from customers who call this “the only serum that works.” Better yet, it’s risk-free thanks to a 90-day guarantee.

Best for Sensitive Eyes: LashFOOD Phyto-Medic Eyelash Enhancer

You won’t have to worry about gluten, phthalate, sulfates, parabens, or fragrances in this clean, fast-acting formula that’s gentle enough for use on sensitive eyes. The dermatologist-tested treatment employs a combination of aloe vera and other herbal extracts to condition and moisturize your lashes, encouraging new hair growth sans irritation. Each tube has a 90-day supply—but you’ll see improvements in just four weeks. One reviewer over the age of 70 admitted she was a skeptic before trying this product, but discovered her “lashes are longer” and “a really thin spot has filled in beautifully.” (Related: What Is Hypoallergenic Makeup—and Do You Need It?)

Best Volumizer: Rapid Lash Eyelash Enhancing Serum

This cult-favorite serum uses ingredients like copper peptides, biotin, hyaluronic acid, and panthenol to fortify your lashes, which reduce hair breakage, increase shine, and make them appear fuller than ever. Plus, the gentle formula and lack of side effects was touted as a win for many reviewers—one person with sensitive eyes said they’ve seen “no adverse reactions” but definitely have longer-looking lashes.

Best for Bottom Lashes: SmartFX Original SmartLash Eyelash Enhancer

Many eyelash growth serums can only be applied along your top lashes, but this smart formula can be applied twice a day to both your top and bottom lashes. A consumer study found that the non-irritating lash enhancer gave 83 percent of users thicker lashes after just 28 days of use, thanks to a combination of nourishing ingredients like peptides and biotin. Plus, it earned over 3,700 perfect five-star reviews on Dermstore’s site from customers who say they’ve seen quick, noticeable results in fullness and length.
