The Eyelash Growth Serums That Really Work
Mascara is good, but these growth-boosters are better.
You know that friend with the ridiculously long eyelashes – the one that swears she was simply blessed by the Gods? She’s probably lying.
While a decent mascara can get you far enough in the lash-lengthening stakes, for a flutter that seriously skims your eyelids, you need an eyelash growth serum.
Promising longer, stronger lashes in a matter of weeks, there's good reason you'll struggle to find a beauty editor that doesn't have one stashed by their bedside. Some are even so effective, you might just be tempted to ditch the mascara altogether (baby steps, ok).
How do eyelash growth serums work?
These mysterious tubes may appear to be magic, but there’s actually scientific reasoning behind the best lash serums on the shelves. Like the hair on your head, your lashes grow and shed according to a four-phase cycle: anagen, catagen, telogen, and exogen.
‘Active’ lash growth serums – in the UK, Revitalash and Rapidlash are the most well-known – contain ingredients that studies suggest are able to keep hairs in the anagen, or growth, phase of the cycle for longer.
These ingredients are known as prostaglandin analogues – and, while they may be the most reliable shortcut to brow-skimming lashes, it's important to know they have also been linked with some unwanted side effects, namely skin pigmentation and irritation. While every product on the shelves in the UK will have been thoroughly tested for safety, it's important to know what you are applying and to do so with caution – especially if your skin is sensitive. Read the instructions (one more time: Read. The. Instructions) and be sure to stop using your lash serum immediately if you notice any irritation or discomfort.
How about lash conditioners?
If you're keen to skip the prostaglandin altogether, you still have plenty of choices. Conditioning lash serums work in a slightly different way. They’re usually packed with amino acids, which are the building blocks of protein. Like the hair on your head, your eyelashes are made up of over 90% proteins, including keratin (for strength) and melanin (for colour). So, more amino acids = better potential for long, strong lashes.
If you’ve spotted peptides on your lash serum INCI list, that’s a good sign too: studies have found these ingredients to have the potential to stimulate lash growth.
Essentially, a conditioning lash serum is a nourishing, nutrient-dense meal for your lashes, providing them with the fuel they need to grow to their best ability.
So, ditch the falsies this season – you no longer need them. Here, discover our verdict on the best eyelash growth products to try now.
The best eyelash growth serums to invest in now
Beauty Pie Lash Fuel Advanced Peptide Serum
Beauty Pie Lash Fuel Advanced Peptide Serum
A powerful alternative to prostaglandin-based products, Beauty Pie’s lash-growth serum contains a specially developed peptide that has been shown to enhance lash length in two weeks. Biotin and soothing panthenol boost the efficacy further, making this the first thing you should be adding to your next Pie haul.
Olaplex Lashbond Building Serum
Olaplex's lash serum combines peptides, biotin, hyaluronic acid and red clover extract – which studies have suggested is able to support hair growth – in one powerful formula. It's free from prostaglandins, and the reviews are glowing.
The reviews for this one are borderline obsessive – and you'll quickly see why. The latest lash-enhancing name to know, UK Lash's active formula uses a low level of prostaglandin analogue alongside peptides and follicle-feeding plant extracts to encourage a seriously full flutter.
RevitaLash® Advanced Eyelash Conditioner
RevitaLash® Advanced Eyelash Conditioner
Revitalash was originally created by an ophthalmologist for his wife, to help boost her lash growth following chemotherapy treatment. It worked so well, the brand is now a leader in the lash-serum space. If your lashes are broken or brittle, this potent peptide blend is a major contender that delivers satisfying results after four weeks.
Rapidlash Eyelash Enhancing Serum
An OG lash growth serum, Rapidlash delivers results to rival the spendiest options for a price that won't make your eyes water. It might take you a little longer to get there, but this peptide-based formula will lead you to your longest lashes ever.
Susanne Kaufmann Lash and Brow Serum
Susanne Kaufmann Lash and Brow Serum
Susanne Kaufmann is the latest brand to create a natural, prostaglandin-free lash and brow serum – and trust us, this one really impresses.
It contains an edelweiss-derived peptide alongside plant extracts with high humectant and emollient properties to fortify brittle lashes. Early users claim results appear to sprout up at the two-month mark, so be patient.
The Ordinary Multi-Peptide Lash and Brow Serum
The Ordinary Multi-Peptide Lash and Brow Serum
Predictably well-priced and reliably results-driven, The Ordinary's peptide-based serum really works to encourage longer, darker lashes. It's not quite as potent as the OGs, but the performance far belies the bargain price tag.
As a make-up brand designed to honour, not mask, what you've got, it makes sense for Kosas to launch its own lash serum. This almost-entirely natural formula contains peptides and vegan keratin in a base of castor seed oil. If you're after strength alongside length, this is good one to try.

Bolstered by circulation-boosting plant extracts, this gentle serum hydrates lashes and encourages keratin production, leading to longer, glossier hairs in four weeks. Try it on both lashes and brows.
Hairburst Lash & Brow Enhancing Serum
Hairburst Lash & Brow Enhancing Serum
Hairburst's eyelash and brow serum is based around peptides, castor oil and hydrating hyaluronic acid. the star ingredient, however is red clover extract, which is said to help hairs anchor into the follicle, keeping them just where you want them for longer.
