As is the case with most beauty products, eyelash growth serums come with some pretty big promises – claiming to deliver all the length, volume and flutter. Yet the question still stands: do they actually work?
Sure, some formulas can indeed help transform even the most brittle and damaged lashes in a matter of a few weeks, to a point when everyone will be quizzing you on whether you're wearing false lashes or eyelash extensions.
However, it's also important to keep in mind that not all eyelash serums are made equal, and some of them may not only prove less effective, but can also result in issues like irritation, stinging and itching.
So, how exactly do you go about picking the right formula? That's where we come in. As seasoned beauty editors with years and decades of product testing experience, we've curated the ultimate edit of the very best eyelash growth serums, having consulted industry experts and tested said formulas first-hand.
From cruelty-free, budget-friendly, dermatologist and ophthalmologist-approved formulas to those that have been especially formulated for sensitive eyes, we've made sure to include something that works for everyone. Here's everything you need to know.

Which eyelash growth serum is the best?
RevitaLash is a brand behind one of the most popular eyelash enhancers to date. This hair serum has been praised by the likes of Meghan Markle, largely due to its ability to target hair growth by simultaneously defending against environmental damage with antioxidant-packed green tea and the BioPeptin complex.
Our former Senior Visual Editor, Chelsea Hughes, reviewed the RevitaLash Advanced Eyelash Conditioner over the course of six weeks, and this is what she had to say: “To sum this product up; I’ve had numerous friends and family physically inspect my lashes to check whether or not I’m lying about them being real. The improvement is phe-nom-en-al!” Now, if this doesn't convince you, we don't know what else will. Other brands that are definitely worth considering include Uklash, Augustinus Bader, Elizabeth Arden, Maybelline, Lancome and Olaplex, to name a few.
How we tested eyelash growth serums
Over the years, the GLAMOUR team – alongside our freelance writers – have tested hundreds of eyelash serums from a variety of brands, ranging in terms of price, ingredients and packaging. We've made sure to assess whether of not the formulas resulted in any irritation or stinging as well as its efficacy and how quick it has helped us achieve optimal results (find out how we test here).

Best volume-boosting eyelash growth serum

Key ingredients: Biotin Peptide, vitamin B5, Myristoyl Pentapeptide-17 and green tea extract.
Review: “The Uklash eyelash serum truly deserves all the hype it gets. It doesn't irritate my sensitive skin and the redness is minimal.

Not to mention, I've started noticing the results after just 2 full weeks of use, which definitely scores extra points in my book," – Sophie Cockett, GLAMOUR's Senior European Commerce Editor.

I've been trialling this formula for over 6 weeks now, and I'm already seeing some promising results, having noticed a sizeable improvement to the length of my lashes as well as volume,” – Fiona Embleton, GLAMOUR's Associate Beauty Director.

Are eyelash serums worth it?
Meet the experts:
- Claire Larsen, global master educator at RevitaLash Cosmetics
- Nima Pourian, founder of Uklash
We have around 200-300 lashes on each eyelid, but we lose roughly four lashes a day. Then, it takes about three months for these full lashes to grow to their original length, before they shed and the whole growth cycle starts again. But in our efforts t to bless ourselves with long lashes (on average, they reach about 1cm in length), we’re constantly putting our peepers under undue stress – meaning the process takes longer.
The ultimate secret to long and naturally thick lashes largely lies in genetics, but achieving long, fluttery lashes is also perfectly doable through consistent and regular use of eyelash growth serums. And before you say it: no, eyelash serums aren't only meant for sparse and thinner lashes. Let's put it this way: even if you're naturally blessed with thicker and longer hair, you would still use conditioner, hair oils and hair masks to nurture it, right? Well, the same concept applies to your lashes.
What causes damage to our natural lashes?
- Even the best mascaras and eyeliners can make our lashes dry and brittle, making them more prone to breakage.
- Vigorous makeup removal can also exponentially increase the amount of lashes we shed each evening.
- Eyelash curlers can place stress at the base of our lashes, prising them out early.
- Long-wearing and waterproof mascaras sometimes require intensive removal process that leaves our skin raw and our eyelashes totally frazzled.
- Then there's the issue of false eyelashes and lash extensions, which can create damage to our hair follicles by overloading and putting too much weight on the lashes.
- Meanwhile, wearing sleep masks can cause friction and tug at lashes, encouraging them to shed prematurely, as well as bad habits like rubbing your eye area at the end of a long day (even though it feels so good).
How long does it take to notice the results?
According to Claire, results usually differ depending on the individual, however, the growth is often noticeable after six weeks of regular, daily use. "We conducted an independent consumer study with 63 participants. After six weeks of daily directed use, 98% reported improved lash appearance, 98% reported healthier-looking lashes, and 98% reported stronger lashes."
Meanwhile, Nima shared that the growth also depends on the stage of “your lash growth cycle.” "Our eyelashes and brows go through a cycle of around three months (12 weeks). This includes a growth phase (Anagen), a transition phase (Catagen) and a resting phase (Telogen)," Nima elaborates. “This is why Eyelash & Eyebrow serums are advised to be used once per day for 8-12 weeks to achieve best results - the same amount of time as a full growth cycle.”
Do eyelash serums have any side effects? Are eyelash serums safe to use?
"Aside from the positive benefits, some users can experience redness or irritation, particularly if they are excessively using," says Larsen.
Similar to many other beauty products with active ingredients, it's always better to tread carefully and do a patch test to observe how your skin reacts to your chosen eyelash serum. “It is very rare that someone would have a reaction, but the eyes can be sensitive so always best to check first," says Pourian. “It is also important to follow instructions correctly and not to overuse the serum.”
How do eyelash serums work?
"Eyelash serums help to grow your natural lashes, making them longer and thicker after continued usage – it is a commitment, but worth it for beautiful, natural lashes," explains Nima Pourian, founder of Uklash. “Eyelash serums absorb into the lash and brow follicles to help stimulate growth, reducing fall out and enhancing the thickness of hair by strengthening roots.”
According to Claire Larsen, global master educator at RevitaLash Cosmetics, eyelash serums are similar to a hair conditioner. "They hydrate the hair with conditioning ingredients for shine and flexibility, to prevent brittleness and breakage, they strengthen the hair with ingredients rich in vitamins and strengthening peptides," she shares.
“They protect the health of the hair with free-radical fighting antioxidants and they enhance the overall beauty of the lashes for healthier lashes.” "A comprehensive formula will contain a blend of ingredients like conditioners, vitamins, antioxidants and peptides to have a multi-faceted approach to beautifying the lashes and keeping them strong and healthier-looking," Claire explains.
