Lustrous, fluttery lashes have always been a beauty holy grail. While the traditional route to getting them has been promise-all mascaras, lash extensions or more controversial lash boosting treatments like Latisse, a prescription strength lash serum that though effective can come with side effects – a darkening of the skin and a change in eye colour. More recently, however, we’ve seen a slew of eyelash serums with promising claims.
Many lash serums work by adding growth-encouraging ingredients like peptides, proteins and conditioning ingredients (commonly vitamin E, hyaluronic acid and castor oil) to the lashes.
But one thing to note is that sadly, this isn’t an overnight experiment. To really see any change, you do have to commit to see any results, and get into the habit of applying it routinely (keeping it by your bedside table is a good idea to help jog your memory.)
And because each person reacts differently to them, some might see results faster than others – though as a ballpark, three months (our lashes have a 90-day cycle) is a good time to look back at your progress.
One way of making sure you’re seeing a difference, is to take a profile shot before and after picture – comparing in monthly intervals. And thing to bear in mind, they tend to work with continual usage – so if you stop using it entirely, the results might not stick around.
Another thing to note is that our eyes, and the skin around it is extra sensitive, so even if a product is hypoallergenic, stop if you notice any irritation and consult your doctor.
We tested a number of eyelash serums over the period of many months to see how efficacious each one was. Above all we were looking for glossier, healthier lashes, with added length as a bonus.

A firm favourite in the beauty industry and one of the OG lash serums, this isthe one to beat. Revitalash works by slowing down the growth cycle of the lashes so that they stay at fuller-length for longer. With one swipe across a dry lash line at night, RevitaLash says you can potentially see a difference in a couple of weeks.
The serum was created by Dr Brinkenhoff, an ophthalmologist, who was looking to help his wife regain her lash confidence after cancer. It contains ingredients like peptides (the building blocks of proteins), moisturising agents (like glycerine) and nourishing botanicals. We found that it applied easily, and that – as its rave reviews suggest – our lashes looked noticeably more conditioned, thicker and longer after roughly six weeks of continual usage. A definite repeat purchase.
RapidLash eyelash enhancing serum
One of the more affordable options, RapidLash aims to strengthen your lashes using a blend of polypeptides and also stimulate growth by using the vitamin biotin. It’s clinically proven to help boost the look of your lashes, with an everyday application that’s pretty similar to Revitalash – you simply paint it along your lash line once a day. The brand says you can expect to see results in as little as eight weeks and while we saw that there was a definite improvement in length and condition in this time, the results didn’t feel quite as dramatic as RevitaLash, though were still noticeable.
Elizabeth Arden PRevage clinical lash and brow enhancing serum
On the pricier end of the market this brow and lash serum (swiped across the lash line or brows) uses a combination of vitamins A, C and E, peptides and lash conditioners to support the natural lash cycle, for glossier and less dry-looking lashes. While the brand says it’s not intended to prevent hair loss or promote growth, but that you can see an improvement in condition in as little as two weeks, we think it’s best suited for anyone with very parched, damaged lashes looking to recondition them. However, after a month of painting it on, we did notice that our lashes looked longer and felt more robust too – a great choice for anyone who wears false lashes frequently to help condition your natural lashes.
Vichy LiftActiv anti-aging serum 10 eyes and lashes
More of a multi-tasker, this eye serum-meets-lash booster aims to target signs of ageing around the entire area and help your lashes to boot. It’s a much less fiddly application than the paint-on lash serums, so a great option for anyone looking for a multi-purpose, fast option. It contains rhamnose (an anti-inflammatory ingredient), ceramides (which help to prevent moisture loss) and instant light reflectors too. While this one didn’t give us the dramatic results some of the others did, it did improve the condition of our lashes leaving them looking healthier and our eye area definitely looked brighter after a month of usage.
Luna Nectar the moon boost tonic for lashes and brows
This cult US brand uses antioxidants and plant-nutrient formulas promising to nourish lashes and brows in just under three weeks, by prolonging the growth phase of the hair follicles. Using ingredients like nourishing vitamin E and argan oil and soothing aloe, after three weeks we did see that our lashes looked visibly glossier, healthier and appeared thicker too. We also liked that it’s vegan, and fragrance-free – and a great choice for anyone looking to recondition their parched lashes.
No7 lash impact serum
One of the less expensive options, this serum – applied at the lashes – is designed to give thicker and darker lashes and brows in eight weeks. It’s hypoallergenic, which is a big USP, and although the brush applicator isn’t the easiest to use this is a great entry level option to the world of lash serums. With ingredients like protein-rich keratin and plenty of conditioning agents, we definitely noticed a gentle difference in the eight-week period. But it wasn’t quite as dramatic as some of the other options.
L'Oreal Paris clinically proven lash serum
Using nourishing castor oil, boosting vitamin b5, moisturising hyaluronic acid, this impressive formula aims to help strengthen the lashes and nourish them. You can even brush it on as a base coat before you apply mascara as it acts like a moisturising mask for the lashes. The brush made it easy to apply and after three weeks we noticed lashes looked more conditioned, and a little longer – although it wasn’t a dramatic change. This could be a great option for anyone looking to up the condition of their lashes post extensions.
UKlash eyelash conditioning serum
Using hyaluronic acid, peptides and biotin as its mainstay this serum is ideal for anyone with sparse lashes looking to beef them up a tad. Its recommended usage period is eight to 12 weeks, so on the longer side. But it does contain similar ingredients to some the pricier serums, which is great. We did have a little redness from this one, which went away after we skipped a night, but there was a visible difference after eight weeks, in both length and condition too.
Indeed labs peptalash
Using a pen applicator, this well-priced option says it can lengthen, thicken and darken lashes, promising more volume in a very short 15 days. It uses plant stem cells from a rare Swiss apple plus a blend of two peptides which aims to create less lash breakage, as well as helping soothe the skin around the eyes as a bonus. This one needed to be used twice a day, and although the pen was a little hard, the results showed more conditioned lashes, with a definite improvement in their health, in 15 days.
Lancôme cils booster activating serum
Definitely the chicest looking of the bunch, this luxury lash serum is infused with hyaluronic acid, a four amino acid concentrate and cicaa reparative plant extract to help nourish the lashes. After a month of usage, we saw a big improvement in the condition of our lashes and a little growth too. The formula was thicker and heavier than the others, making it ideal for bedtime use – it felt like a hair mask for the lashes. It could be one for anyone with very dry lashes, as a brilliant conditioning treatment.
The verdict: Lash serums
RevitaLash Advanced was definitely the one that made the most dramatic impact on the length of our lashes. But we also liked Luna Nectar’s conditioning and more holistic approach for a gentler approach to reconditioning your lashes – so that could be a great regular-use option too.
