While UKLash may look sleek with its minimal packaging and stylish bottle, the product itself left us with more concerns than compliments.

The formula is marketed as hypoallergenic and gentle, but several testers noted mild stinging or redness around the lash line after application, suggesting that it may not be as irritation-free as claimed. The thin brush also makes it easy to accidentally overapply, leading to serum dripping into the eyes – not exactly the smooth, seamless experience the brand promises.

As for results, while a few reviewers did notice changes after a couple of weeks, the growth was inconsistent. Some saw no difference at all, while others felt their lashes became brittle over time, raising questions about the long-term health of lashes with continuous use. The claim that you can stop wearing mascara altogether feels exaggerated.

Although it can technically be used on brows too, we didn’t find it nearly as effective in that area, making its “versatility” claim feel more like a marketing angle than reality.

In the end, UKLash may be budget-friendly and beautifully packaged, but the inconsistent results, potential irritation, and lack of lasting impact make it far from a reliable favourite.

Groa Lash Serum promotes itself as a clean, prostaglandin-free formula with peptides and biotin. On the plus side, it is vegan, cruelty-free, and does leave lashes feeling a bit softer and more conditioned. However, when it comes to actual lash growth, results were minimal — more like a light lash moisturizer than a true growth serum. The thin, runny texture makes application tricky, and some users experienced irritation when it seeped into their eyes.

While the price point and “clean beauty” appeal are nice, those seeking dramatic lash growth may be left underwhelmed.

RevitaLash has built a strong name for itself in the lash serum category, but its reputation comes with a steep price tag. At nearly £90 a bottle, it’s hard to ignore that several other serums deliver very similar — if not better — results for a fraction of the cost.

The formula does contain peptides and biotin, which helped some of our testers see modest improvements in lash length, thickness, and shine after a couple of weeks. But the gains were far from dramatic, and like all lash serums, the results vanish once you stop using it.

The packaging is simple, the serum works to an extent, but the high upkeep cost makes it difficult to justify when more affordable options can offer equal or better performance without draining your wallet.

This lash serum positions itself as a science-backed formula, but the brand’s claims of being “clinically tested” are questionable, with no real evidence of proper trials. At such a high price point, you’d expect more transparency — and a bottle that lasts longer.

Performance-wise, it does condition and add some length and thickness, but the improvements were modest, hardly enough to justify the cost. To make matters worse, the formula includes sodium benzoate, phthalates, and parabens — ingredients known to trigger irritation, redness, and itchiness for sensitive users.

Some online reviewers have even reported changes in iris color, which is alarming, though we didn’t experience this firsthand. While the 30-day money-back guarantee offers a little reassurance, the risks and inflated price make this serum difficult to recommend.

With its luxury price tag, you’d expect Lancer Lash Serum to deliver extraordinary results — but it doesn’t. While our testers did notice some added length and fullness within a few weeks, the improvements were no better than those from much cheaper serums, making the cost hard to justify.

The formula includes biotin, panthenol, and glycosaminoglycans, which help condition and keep lashes feeling soft. The sleek packaging and eyeliner-style applicator also make it easy to use. But despite these positives, the serum contains potential irritants like the triple peptide complex, which can trigger redness, swelling, and itching in sensitive users.

What’s more, the brand provides no solid scientific evidence that this serum truly stimulates lash growth — and with no money-back guarantee, the high upkeep feels like a gamble. Overall, it works, but not well enough to warrant the £90 price tag when more affordable options perform just as well, if not better.

Neulash by Skin Research Laboratories comes in sleek packaging and boasts amino acids, fatty acids, and hydrating ingredients like sodium hyaluronate. On paper, it sounds promising, but in practice the results were underwhelming. Lashes grew slightly longer, but the promised thickness and strength never really appeared, even after six weeks of consistent use.

At around 6ml per bottle, it’s still expensive for the minimal payoff, especially when considering ongoing upkeep. More concerning is the inclusion of prostaglandin — an ingredient known to irritate sensitive skin. Several of our testers experienced redness and itching, with one forced to stop altogether due to a burning sensation.

While it may work for some, the combination of high cost, modest results, and potential irritation makes Neulash hard to recommend. Cheaper serums not only perform better but are also less risky for sensitive eyes.

This mid-priced serum from Cosmetic Alchemy has been on the market for years and has built a loyal following, but it comes with clear limitations. The small bottle runs out within a couple of months, so maintaining results quickly becomes an ongoing expense.

Formulated with mostly natural ingredients like lupinus albus seed extract, almond oil, silica, and panthenol, it’s marketed as gentle and versatile — suitable for both lashes and brows. While our testers experienced only mild, temporary itchiness, reports of burning, redness, and irritation from other users make it less ideal for those with sensitive skin.

In terms of performance, the serum does deliver some improvement. Lashes appeared slightly longer and fuller, but nowhere near the dramatic results many hope for. If you’re after a subtle enhancement, it’s passable, but for anyone chasing bolder, thicker lashes, better options exist at this price point.

Packaged in a sleek black bottle, M2 Lash Serum certainly looks premium — but the performance is far from it. Despite a hefty £128 price tag, our testers saw almost no improvement. Lashes remained the same, with only one reviewer noticing the slightest thickening, nowhere near the 50% growth the brand boldly claims.

The formula contains biotin, hyaluronic acid, and M2’s own “Prodew” nutrient blend, which are supposed to condition and activate lash roots. In reality, they delivered little beyond basic hydration. While the product is dermatologically tested, non-irritating, and cruelty-free — which we appreciate — that’s hardly enough to justify the cost.

Overall, this was the weakest performer in our testing. At least it comes with a manufacturer’s guarantee, so you can get your money back when the results don’t show up.

Elizabeth Arden is a globally recognized brand, so expectations for their lash and brow serum were high — especially at £90 a bottle. Marketed with a triple peptide complex, vitamins, and botanicals, it promises healthier, thicker, revitalized lashes. The catch? The brand carefully uses the word “support,” meaning there’s no real guarantee of actual growth.

After testing, our lashes did feel softer, looked shinier, and appeared healthier overall. But in terms of added length or fullness, there was virtually no change. The clinical claims are also misleading: Elizabeth Arden cites a 100% success rate, but this only refers to improved lash condition, not growth.

For what it delivers, a simple natural oil like olive oil could achieve the same conditioning results at a fraction of the cost. At £90, it feels more like paying for the name than for true performance.
