Trust us, these eyelash growth serums will give you the longest, thickest lashes of your life (2024)

Uklash Eyelash Serum

UKLash's serum has been a fan-favourite for years, and the incredible before and after transformation pics prove why.

Its impressive formula is co*cktailed with a bunch of high-grade ingredients – like pentapeptide-17 and vitamin B7 – to encourage growth by stimulating keratin (protein) production, which is already present in your lashes.

Plus, if you aren’t convinced, you can get a 100-day money-back guarantee. It’s a win-win really.

RapidLash Eyelash Enhancing Serum

RapidLash is one of the most affordable and effective eyelash growth serums on the market.

Apply the clear serum to your upper lash line once or twice a day (morning and night) for eyebrow-skimming lashes. You can also stock up on an eyebrow version (RapidBrow) which is just as effective.

Beauty Pie Lash Fuel Advanced Peptide Serum

Members price: £19.50

Trust us when we say that Beauty Pie's Lash Fuel serum is always out of stock, so get your fill now if you want brow-skimming lashes.

What's the secret sauce? It's all about peptides, which are chains of amino acids that make up proteins in the hair structure. When you feed your lashes with this serum, the peptides will stimulate quicker and stronger growth, resulting in enviously dense and fluffy lashes.

Stay loyal to it and you may see results in as little as two weeks.

RevitaLash Advanced

This one needs little introduction: Revitalash was created by an ophthalmologist who wanted to help his wife's confidence after she lost her lashes to cancer.

It uses a co*cktail of peptides (the building blocks of protein) and antioxidant botanicals to stimulate hair growth and density, while protecting your lashes from environmental damage.

You can also grab the serum in 2ml, 3ml and 3.5ml tubes which is a pretty handy feature.

Glow For It Lash Growth Serum

If your 'For You' page looks anything like ours, you would have spotted this pink tube making many appearances. Glow For It's Lash Growth Serum has developed quite the hype, with TikTokers raving about how the formula has improved the length and strength of their lashes.

Naturally, we had to test it for ourselves and we can confirm that the hype is warranted. In just two weeks we saw a noticeable difference in the density of lashes (we're waiting on length). Plus, it uses natural ingredients, like pumpkin seed extract, ginseng and calamus root, to stimulate hair follicles.

Blink Brow Bar Luscious Lash Oil

Blink Brow Bar may be your go-to for microblading or a lash lift but know that the London-based salon also has some stellar products to use in your home.

The Luscious Lash Oil is described by the brand as a "health shot for the lashes". Rather than prostaglandin it calls on a unique and plant-based oil blend to condition the lashes and stimulate growth – there's castor oil, jojoba, apricot kernel and rosemary, just to name a few.

Sweed Eyelash Growth Serum

Sweed’s clever serum is boosted with nourishing and growth-stimulating ingredients to encourage fuller, longer lashes.

Bolstered by vitamins and hyaluronic acid, the lightweight formula feeds your lashes with hydration while strengthening brittle hairs. Alongside added peptides, the serum aids keratin growth to result in silky, longer lashes.

I also appreciate the super-slim brush to ensure that the product is only applied directly onto the lash line, and not the surrounding skin.

Maybelline Lash Sensational Mascara Serum

If you’re scraping the sides of your expensive tube and need one to keep you going till payday, here’s one I'd recommend.

The Lash Sensational Boosting Serum is enriched with arginine (a form of amino acid) and provitamin B5 to strengthen and improve density.

After a few months of consistent use, it helps to give your lashes a fuller-looking effect but, side note, it doesn’t shine as brightly in the lengthening department.

Also, one thing to be aware of, it comes with a mascara-style wand rather than a brush, which you may love or hate. However, with a price tag that’s cheaper than a takeaway pizza, how can you complain?

Augustinus Bader The Eyebrow and Lash Enhancing Serum

This pick isn’t something you’d casually pick up at the checkout while shopping for a new mascara.

It’s an investment for those who are serious about the length and long-term health of their lashes – because when I say it works, it works.

If I can’t believe it myself, the number of times I’ve had people ask if I’m wearing falsies proves it. It’s hard to part with the cash but, if you want to ditch the lash extensions for good, it’s the best way forward.

Scandinavian Biolabs Eyelash Growth Serum

Scandinavian Biolabs' Eyelash Growth Serum is the perfect fit for the sensitive souls out there. The formula is crafted with scientists and medical doctors to ensure that each ingredient is as safe as it is effective.

Dedicate a daily swipe along your lash line and over time you'll notice thicker lash hairs sprout. And just to show how confident the brand is in this serum, you can get a full refund after 150 days if you don't see the results you're after (although we bet you will).

Olaplex Lashbond Building Serum

If you’re an Olaplex girlie, you’ll be thrilled to know that the brand also has a lash serum – and this is like no other I've tried.

Like your hair needing a healthy scalp to grow from, the same rule applies to your lashes. If your barrier is compromised (think: mascara wiggling and excessive scrubbing) it’ll prevent long lash growth.

Lashbond uses the brand’s bond-building technology to support the skin around your lash line, as well as peptides to stimulate growth. It's a quick worker too, with results showing after a few weeks.

The Ordinary Multi-Peptide Lash and Brow Serum

The Ordinary is famed for its ingredient-led formulas that genuinely do bits. So, nothing is different with its lash serum – and at a budget-friendly price which we could all do with right now.

While the results won’t be as transformative as costly alternatives, with loyal use it’s a great middle ground if you’re wanting to boost the overall health of your lashes.

Use twice daily and the peptide complex helps to stimulate denser, fuller lashes.

There are so many factors that can contribute to lash loss. Tugging too hard with makeup remover is a main culprit, curlers can put stress on your lashes and even something as innocent as an eye mask can rub and cause brittle and weak lashes. Not to mention falsies and extensions – that's a different story.

Luckily, a top-quality lash serum with a nutrient-packed formula can recondition lashes and stimulate faster growth. So, what's the secret?

It all started with prostaglandin – a lipid-based ingredient used to treat glaucoma that was later discovered to have lash-lengthening benefits. But if you’re looking for a formula that contains high levels of prostaglandin, you won’t have much luck as earlier formulas were subject to controversy for causing low-risk side effects (think: redness and pigmentation).

So, as you may have guessed, most serums are now fortified with a much weaker prostaglandin base – or an alternative active – so that even the most sensitive can get on with them. Peptides and proteins also feature heavily, working to stimulate growth and encourage dense, dark lashes.

While every product on the market will have been tested heavily, and many are dermatologically and ophthalmologist tested too, it's important to read the instructions and follow them fully as some serums may suggest a patch test.
