World’s bestselling lash serum launches new advanced formula with results in 6 weeks

If your eyelashes are fine or sparse, using one of the best lash serums can really help to boost their growth – and this new launch sounds like one you need to try.

UKLASH, the world's number one lash serum brand – which already has its bestselling £38 Eyelash Serum – has just dropped a new formula that promises to be its most advanced yet. Complex Peptide Eyelash Serum, priced at £42, contains a cocktail of six different peptides to strengthen and support lash growth, with results in as little as six weeks.

In UKLASH's tests, 88% of testers reported longer lashes after six weeks of using this serum every day, and 86% said that lashes looked thicker.

If your brows are your biggest beauty bugbear, there's also a UKLASH Complex Peptide Eyebrow Serum, also £42, which has 86% of testers claiming it made their brows look fuller and healthier.

Tempted by both? You can buy the duo together for £75.60, saving you over £8 compared to buying them individually.

This supercharged new lash serum may have only just launched but it's already racking up five-star reviews from testers who have already been using it for a while.

"I started noticing a real difference at around 2/3 weeks and by week 6 I am speechless," one happy customer reported. "I used to have such sparse and thin lashes and now they're so long and much thicker. I will be forever restocking on this product!"

"I must say I am blown away by the results," another wrote. "I have only used it for 6 weeks but my lashes are a lot stronger and longer than before! I also love how easy it is to apply!"

Meanwhile a third review simply reads: "This serum actually works, results in 12 weeks. Stronger, thicker lashes. Yes please. I really do recommend this product."

Sounds like this a set to become another bestseller!

Other lash serums we've tried and love include Revitalash Advanced Eyelash Conditioner. At £129 it's pricey, but it's our beauty editor's tried-and-tested favourite for delivering noticeable results.

And if you're a fan of Olaplex hair products, you might want to try Olaplex LashBond Building Serum, £64, which has dozens of five-star reviews on LookFantastic.
