False eyelashes with a coat of mascara are just one of the various methods that can instantly deliver longer and thicker-looking lashes, but comfort is not always promised. Rather than have to glue on a pair of fake eyelashes daily, an Amazon eyelash serum has made headlines for its promise to deliver eyelash growth in as little as two weeks. That way you can enjoy the look of your natural eyelashes and ditch the lash glue.

Luxury eyelash growth serums come with a designer price tag, but what’s unique about KL Killer Lashes is its ability to help naturally stimulate hair growth for only $30, making it a major beauty deal. The formula relies on ingredients such as Myristoyl Pentapeptide-17, which helps to stimulate hair follicles while the use of biotin increases the rate of follicle growth.

KL Killer Lashes Eyelash Serum

KL Killer Lashes serum comes with a tube of gentle gel-like formula that’s sensitive skin-friendly and provides results in as little as two weeks when used regularly, according to the brand. Included is an applicator brush that you should apply to your lash line. From there, the serum will help widen, lengthen and thicken your lashes so you have fuller eyelashes over time. You can apply the beauty product any time of the day, but some reviewers have stated they like to put it on each night before bed.


Verified Amazon reviewers can’t get over how effective the serum has been, with one stating, “I [finally] have lashes I can see.” When it comes to applying the serum to your eyes, shoppers have said that it’s a “super smooth application with noticeable results.”

One reviewer even praised how their eyelashes are noticeably longer and thicker saying “applying mascara is a breeze because I don’t have to apply layer after layer.” Yes, you’ll still want to add a coat of mascara after you use the Killer Lashes product, as it’s only a growth serum and does not add color.
