The Best Lash-Lengthening Serums (Including Olaplex's New Launch)

Tired of having to apply layer after layer of mascara to lengthen your lashes? Let our edit of the best lash serums help you achieve longer, stronger lashes without all the hassle – and yes, they really can work.

With tried-and-tested recommendations from The Ordinary and Revitalash, as well as Olaplex’s super exciting new launch, if you want naturally longer and fluttery lashes (that won’t smudge, flake or require a trip to a semi-permanent makeup artist) these are the best lash serums to try.

What makes a good lash serum?

There are multiple reasons why your lashes might lack volume and length. Of course, there’s your genetics (some people simply have longer lashes than others), but aggressive removal of your mascara, overuse of eyelash curlers, frequent lash extensions, and even eye irritation can play a massive role in lash condition and breakage, ultimately leading to shorter lashes.

That’s why good lash serums are often really focused on nourishment, helping to recondition your lashes and support their growth (just like a hair mask might do for the hair on your head). However, to supercharge lash growth, you’ll want to look out for certain active ingredients too.

Prostaglandin – a lipid-based ingredient originally used to treat glaucoma – is perhaps the best-known for its lash-boosting effects, but its use is being phased out and is now only present in small doses (if at all) to avoid irritation and potential darkening or discolouration of the eye area. Other hero ingredients to look out for that are a lot more gentle (but still effective) include peptides, hydrators, and proteins, which work by stimulating hair cell production to boost growth.

The best lash serums for length and strength

OLAPLEX

The iconic haircare brand behind the hair damage-beating No.3 Hair Perfector has launched a repairative serum for your lashes. It contains all the heroes you love – a peptide complex and biotin for lash strengthening plus hyaluronic acid for nourishing hydration – aiming to make lashes not only look longer, but thicker too.

RAPIDLASH

One of the best-known lash serums on the market, this one is our recommendation if you have very brittle lashes (for example, after a lash lift or extensions). With its blend of peptides, biotin, amino acids and hydrators such as panthenol, it deeply conditions your lashes with impressive results if you are patient.

REVITALASH

If you don't want to give up your waterproof mascara (despite the fact that scrubbing it off can potentially damage your lashes), this serum can help. It's designed to be applied along your lash line pre-mascara, helping provide strength and flexibility to your lashes to prevent damage. The cocktail of botanicals and peptides then promote further growth too.

THE ORDINARY

This serum by The Ordinary is for your brows and your lashes, meaning it's especially good for anyone who overly embraced the 90s skinny brow trend. It also has a particularly small and delicate soft-brush tip for precise application of the peptide-rich formulas – to even your smallest hairs.

UKLASH

A social media-darling, UKLash's serum has hundreds of five-star rave reviews to support its lash-lengthening prowess. The most enthusiastic reviews (which we echo) are from those with thinner, coarse lashes, as the biotin peptide formula contains vitamin B5 and green tea extract to promote healthy lash growth.

SWEED

Sweed's formula is specifically designed to alleviate irritation to sensitive eyes, and its vitamin-rich formula also aims to make your eyelashes both more voluminous and glossy (aka another key attribute of healthy hair). You can thank the inclusion of pumpkin seed extract, hyaluronic acid and keratin peptides for that.
