We tried the best eyelash growth serums to see if they actually work
Spoiler: they do
Eyelash growth serums really can have magical effects. Yes, you can rely on a great volumising mascara, but that will only get you so far. You need an efficacious serum to take your natural hairs from stubby to sky-high.
Many come with bold claims; they promise towering, fuller lashes within a matter of a few weeks. Some, truthfully, are a fad, but if you find the right formula and are willing to spend more than a fiver, there are a trusted handful that the Cosmo beauty team won’t go without.

How do we test lash serums?
To bring you the very best eyelash growth serums, I've examined ingredients, ease of application and the results of each and every tube. Of course, everyone will have a different growth journey, but the ones that made it into my edit delivered impressive improvements to the length, density and condition of the lashes when used regularly.
They're also easy to use and apply directly onto the lash line without spilling onto the surrounding skin – and if you're sensitive prone, you'll find this especially important. Price point plays a role too. I'm a big believer that if you want to see results, you have to spend more than a fiver. But, to cover all bases, I've included some budget players that do a damn good job too.
So, if you're looking to ditch the falsies and are in search of eyebrow-skimming lashes, take a scroll below. The UKLash serum has remained a loyal must-have (oh, and fyi, the UKLash hair growth serum is now a thing) and while it may be spenny, I can testify that Revitalash genuinely works.
