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).
Enter: our edit of the best eyelash serums to nourish and strengthen your lashes properly…
Best eyelash serum overall
Why we love it: A gentle yet mighty formula that's developed by physicians and comes clinically approved by both ophthalmologists and dermatologists. It contains a biopeptin complex packed with biotin, green tea, peptides and lipids, which work together to help strengthen lashes and stimulate healthy hair growth. Plus, this bestselling lash growth serum is also packed with plenty of natural ingredients, including plant and flower extracts, as well as vitamins and antioxidants. And did we mention it's also hypoallergenic, oil-free, vegan, cruelty-free and suitable for sensitive skin? Truly the best of the best.
Key ingredients: BioPeptin Complex, ginseng and Swertia Japonica extracts, saw palmetto, amino acids and vitamin B.
Review: “I started to see the difference after 3-4 weeks of use, so much so that everyone around the office started asking whether I was wearing eyelash extensions. I didn't notice any irritation whatsoever, and the results speak for themselves,” – Mayola Fernandes, GLAMOUR's Commerce Writer.
Best volume-boosting eyelash growth serum
Why we love it: Fortified by nutrient-rich ingredients that stimulate keratin growth such as grape seed extract, swertia japonica extract, pentapeptide-17 and vitamin B7, this viral eyelash serum is 100% worth the hype. It lengthens and strengthens your lashes at the same time and is even suitable for wearers of both false lashes and eyelash extensions. It's also reasonably affordable when it comes to lash serums, which is always a big plus in our book.
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. It only took me a couple weeks of use to start notice improvement and by week 8, the results were undeniable. All that for under £40? Yes, please.” – Neamh Randall, GLAMOUR's Commerce Photo Editor.
Best eyelash serum for quick results
Why we love it: Looking to achieve naturally longer and fuller-looking lashes? Say no more. Powered by a blend of amino acids, prostaglandin, peptides and hyaluronic acid, this moisturising eyelash serum will give you what you want and then some. And although it's certainly an investment, the good news is that it's frequently on sale on Amazon for a fraction of the price. Suitable for people who wear contact lenses and promises visible results in just 4-6 weeks.
Key ingredients: L-Proline, hyaluronic acid, vitamin E, panthenol, glycerin and aloe barbadensis leaf juice.
Review: “I've used the GrandeLASH-MD Lash Enhancing Serum for just under 4 weeks, and judging by the impressive results, this might just be one of the most effective eyelash growth serums I've tried. 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.
Best eyelash growth serum for length
Why we love it: Proven to improve the appearance of your lashes and boost their natural length as well as volume, this eyelash enhancing serum is enriched with Hexatein 1 Complex, a special cocktail that combines six high-grade ingredients: peptides, biotin, amino acids, panthenol, soybean oil and pumpkin seed extract.
Key ingredients: Hexatein 1 Complex, amino acids, pumpkin seed extract, biotin and panthenol.
Review: “I'm always on the lookout for a quality lash serum, and this iteration from RapidLash is definitely one of my favourite formulas. I was first intrigued by its affordable price, but what impressed me most was the boost of length that I noticed after 5 weeks of use, which worked amazingly alongside my go-to mascaras,” – Fiona Ward, GLAMOUR's Acting Website Director.
Best affordable eyelash growth serum
Why we love it: When it comes to affordable yet reliable beauty products, not many do it better than The Ordinary. This water-based eyelash and eyebrow serum is suitable for all skin types and has a lightweight, non-greasy formula that nurtures both the hairs and skin. It comes with 11 different active ingredients, including arginine, four peptide complexes and a whole set of natural extracts to give your lashes and brows the boost they deserve.
Key ingredients: Myristoyl Pentapeptide-17, Biotinoyl Tripeptide-1, Oligopeptide-2, Acetyl Tetrapeptide-3 and caffeine.
Review: “I'm a firm believer that quality beauty products shouldn't always come with a premium price tag, and this eyelash serum from The Ordinary is proof. 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.
