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?).

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)

This multitasking serum 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 more than 21,000 five-star ratings on Amazon, happy shoppers praise the "miracle bottle" as an "affordable option" that actually works! 

"I've been using it for two months now and OMG...it's legit," one reviewer wrote. "I look like I wear fake eyelashes and I love it! I have used it religiously every night before I go to bed and I could probably go down to one time every other night...but I'm kind of enjoying having ridiculously long lashes." 

Best On Amazon: Grande Cosmetics GrandeLash-MD Lash Enhancing Serum

Reigning number one on Amazon's best-sellers list for lash enhancers, the GrandeLash-MD Lash Enhancing Serum brings short and brittle lashes back to life with a superstar blend of strengthening and nourishing ingredients. Among them are hyaluronic acid, amino acids, and vitamin E. This pick also comes with a soft-tip, liquid liner-type brush that's designed to deposit the serum along the upper lash line with precision, meaning that no product goes to waste. More than 14,900 shoppers have given it a five-star rating and many shared that it takes at least three months of consistent usage to see results. 

"I've been using this product for over a year...I love it," raved a shopper. "My lashes are so long and have become darker. When I wear this with my good mascara, people always ask if I have falsies on — and I'm a blonde! [I] highly recommend, especially for us gals over 40 who need some thickness and length to our lashes."

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)

"This product is amazing and [I] highly recommend," shared another shopper. "I have used this for six weeks and I cannot believe the growth. My lashes were damaged from using the eye curler. It is expensive but if you want healthy-looking lashes, this is the product."

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 $15 Amazon find has more than 4,300 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

This 4.8-star rated lash serum from EssyNaturals is clinically proven to boost thickness and length in just three weeks of daily use. Not to mention, users saw a 55 percent increase in 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. In fact, 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. 

Another wrote, "There's no mess or fuss. It's just like putting on eyeliner. Always the skeptic, I wasn't sure anything was going to happen. Until I noticed my lashes getting longer and thicker about three weeks in. I was so excited!" 

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 gently 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. (Related: 15,000 People On Amazon Are Obsessed with This Dual Lash and Brow Serum)

"This is my second tube and I am very pleased with the results," one Nordstrom customer said. "I apply two times 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." 

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. No wonder why it has more than 900 perfect ratings! 

Best for Anti-Aging: Vichy LiftActive Serum 10 Eyes and Lashes

You'll love that this anti-aging serum not only quickly tightens and moisturizes the gentle skin around your eyes through a revitalizing dose of peptides and hyaluronic acid, but also boosts the length and shine of your lashes over time. Best of all, it takes just one drop of the serum to effectively cover your entire eye area in its wrinkle-reducing, firmness-boosting formula. 

"It does not sting and it goes on so smoothly," one said. "I love that the pump delivers the exact amount-my previous eye cream was in a tube and I always ended up dispensing too much of the product. I have noticed a difference after only a couple of weeks. Someone even complimented me on my eyelashes. The low price is a bonus."

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 such as 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?)

"I've tried a number of lash serums; several didn't work, and the ones that did were too irritating for my eyes," one Dermstore shopper began their review. "I've been using this one for several months now and not only do my lashes look darker, fuller, and longer, I've experienced no irritation… The longer I use this one the better the results. Excited I've finally found a serum that works!" 

Best Drugstore Option: Rimmel Lash Accelerator Serum

For noticeably longer, fuller lashes without the luxury price tag, this drugstore accelerator serum is a great option. It's packed with the same peptides, biotin, arginine, and castor oil often seen in pricier formulas, and one five-star reviewer said they used to pay $150 for eyelash growth serums, only to discover this $8 alternative actually gave "better results." (Related: The Skin-Care Products Derms Would Buy If They Had $30 to Spend At the Drugstore)

Another shared, "After having lash extensions for four months, my natural lashes were short and thin. I needed something to nourish them and help them grow, so I decided to try this. I've been applying it to my lashes and lash line before bed for about three weeks now and I can definitely tell a difference. My lashes look amazing." 

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 were touted as a win for many reviewers. For one person with sensitive eyes, they've seen "no adverse reactions" but definitely have longer-looking lashes.

"I have tried several brands of eyelash renewal products and this is the only product that increased my lash volume and length," another customer shared. "And I experienced an added bonus of lash darkening. I have naturally blond eyelashes and Rapid Lash has darkened them to the point that I do not always feel the need to use mascara."

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 a near-perfect 4.8-star average rating on Dermstore's site from customers who say they've seen quick, noticeable results in fullness and length.

"Let me just say, it was well worth the money," declared one shopper. "I've used it twice a day per [the] directions, and after just three weeks my lashes are growing thicker and longer! Ladies, if you're thinking about buying, do it! After stopping lash extensions, my natural lashes were thin and few. Now I'm on a natural lash journey and this product has been magical." 

Best with Hemp: Vegamour Gro+ Advanced Lash Serum

Vegamour gave its best-selling volumizing serum a major update by adding a dose of full-spectrum hemp oil. This unique addition helps the rest of the plant-based formula's bioactive ingredients — including mung bean, red clover, curcumin, and magnolia bark — better penetrate the hair follicle to stimulate growth without causing irritation. The brand promises you'll see serious results in 30 days, and a few reviewers say they saw noticeable growth in even less time. (Related: What's the Best Full-Spectrum CBD Oil?)

"I'm Asian and my lashes are naturally short, sparse, and straight," began one shopper. "I started noticing a tiny bit of lift at the ends of my lashes after just one week of consistent two-time daily application, and now a month later I can tell my lashes and thicker and fuller." 

Best for Damaged Lashes: Skin Research Laboratories neuLash Lash Enhancing Serum

Whether your lash damage is the result of extensions and lifts or copious amounts of mascara and falsies, a nourishing formula like the neuLash Lash Enhancing Serum will nurse them back to health. Inside, peptides, biotin, and panthenol join forces to strengthen, condition, and rejuvenate the follicles to boost your lashes' thickness and length. They also get a dose of vitamins and minerals from pumpkin seed extract, which blankets your lashes in fatty acids, vitamin B, zinc, and iron to make them softer, fluffier, and more resilient. 

"I had eyelash extensions for months and after removing my lashes, I chose to look for a lash serum to help with growth and strengthen my lashes," said one Dermstore shopper. "Within one week, my damaged lashes were making a comeback! After three months now of using it, my lashes are so long and curly! People ask me if these are my natural lashes. They are so strong and long." 

Best Primer: L'Oreal Paris Voluminous Lash Boosting Conditioning Primer

Grow your lashes while increasing their volume with this multitasking primer from L'Oreal Paris. The drugstore-favorite formula can be worn with or without mascara, but when it's used as a primer, you'll notice an instant boost in thickness and length. In fact, it also helps prevent your favorite mascara from clumping or flaking thanks to its iron-strong grip. For some shoppers, the conditioning primer, which uses hydrating ingredients to nourish and prevent breakage, even makes their straight lashes hold a curl. This Amazon best-seller currently has more than 21,000 five-star ratings from reviewers.  

"I struggle with making my lashes look fuller and longer without looking clumpy," one wrote. "The primer went on easily, dried quickly, and I could immediately see results in the length and thickness of the lashes — before I ever applied mascara."
