7 Beauty Editor-Approved Lash Serums To Invest In

From Russian extensions and keratin lash lifts to tinted mascara and magnetic falsies, there are so many products and treatments that boost the length and thickness of scant eyelashes. But as effective and popular as these treatments may be, it’s hard to ignore the allure of lash growth serums.

Currently trending, lash serums boast ingredients such as biotin, hyaluronic acid and peptides, and claim to lengthen and thicken sparse lashes naturally, without the need for makeup, lash glue or a lengthy salon appointment – all in a few weeks. But do they really work? And how do you choose the right one for you?

Ahead, we round up seven lash serums adored by beauty editors, influencers and lash obsessives alike.

Reviewers claim that this lash serum is best for boosting the thickness, rather than the length, of lashes over time. So if yours are on the scant side, this is one for you.
Eyelash Emporium Stunt Double Lash Thickening Serum, $19.95 Buy
This lash serum is on the pricey side but beauty editors and influencers can't get enough of it, and for good reason. Lash growth and thickness is pretty much unrivalled thanks to hair-stimulating ingredient MDN, as well as strengthening biotin and hydrating hyaluronic acid. The key is consistency.
M2BEAUTE Eyelash Activating Serum, $128.00 Buy
This lash serum works fast and a little goes a really long way. It's filled to bursting with peptides (essentially proteins), which are like lash food for stubbornly short hairs. Users have reported a noticeable growth spurt in as little as two to three weeks.
RevitaLash Advanced, $125.00 Buy
The original and, as some might argue, the best, RapidLash uses amino acids, proteins and nourishing oils to encourage length and thickness akin to natural lash extensions. The five-star reviews speak for themselves.
Rapidlash Eyelash Enhancing Serum, $39.99 Buy
This lash serum has countless reviews, with beauty lovers waxing lyrical about the lusciously long yet convincingly natural results in just six weeks. Top tip: take care not to get the formula inside your eye or too close to the lash line to avoid sensitivity.
Grande Cosmetics Lash Enhancing Serum, $51.36 Buy
Regularly treating lashes and brows with this conditioning and strengthening gel serum helps to fill out sparse patches and boost brittle hairs, so they are less likely to break or fall out.
Rimmel Lash Accelerator Serum, $17.99 Buy
This smart lash serum boasts proteins which prompt hair follicles to stimulate and speed up hair growth. Apply twice daily, morning and evening, for lashes that appear wispy and full.
XXTRALASH Regenerative Eyelash Serum, $60.00 Buy
