If your mascara just isn’t giving you the lash moment you’re after, a good lash serum could be worth adding to your routine. Whether you want lashes that look longer and fuller, need a little extra conditioning, or simply want to give your lashes some TLC, there’s a formula to suit.

We’ve rounded up five of our favourite lash serums, from TikTok-famous formulas and sensitive-eye options to an affordable pick that won’t have your beauty budget crying.

SWEED Pro Lash Growth Serum: The All-Rounder

If you’re not quite sure where to start, SWEED Pro Lash Growth Serum is our all-rounder. Its peptide-powered formula combines conditioning ingredients including panthenol, hyaluronic acid and vegan keratin to help lashes look stronger, fuller and healthier.

What really earns it a place on our list is its versatility. You can use it on your brows too, making it a great choice if you want one easy treatment for both.

Why We Love It: It’s a brilliant all-round option that combines lash conditioning with the convenience of a two-in-one lash and brow serum.

Glow For It Lash Growth Serum: The Viral TikTok Fave

 

If you’ve spent any time on TikTok, you’ve probably seen Glow For It Lash Growth Serum pop up on your For You page.

Its peptide-focused formula is designed for daily use and is aimed at helping lashes look longer, thicker and fuller. It’s also vegan, making it a popular choice if you are looking for a formula that aligns with your beauty preferences.

Why We Love It: It’s the one for anyone who loves discovering the next viral beauty product and wants to see what the hype is about.

RevitaLash® Advanced Sensitive: The Sensitive-Eye Option

 

The eye area is delicate, so if yours tends to be particularly sensitive, choosing a lash serum can feel like a bit of a minefield.

RevitaLash® Advanced Sensitive was created with sensitive eyes and lashes in mind. Its Revitasome® Technology delivers a combination of peptides and conditioning ingredients in a formula designed to be gentle around the eye area.

Why We Love It: If sensitive eyes have put you off trying a lash serum, this formula was specifically developed with sensitive eyes and lashes in mind. 

OLAPLEX LASHBOND® Building Serum: The Bond-Building Formula

You probably know OLAPLEX for its haircare, but did you know the brand has a lash serum, too? LASHBOND® Building Serum uses OLAPLEX Peptide Complex Technology™ alongside hyaluronic acid and biotin to help condition lashes while supporting a longer, thicker-looking appearance.

It’s a lightweight, clear formula that’s easy to add to your usual routine, and OLAPLEX says you may start to see visible results in as little as four weeks when used twice daily.

Why We Love It: If your lashes are looking a little worse for wear and you want a serum that focuses on both conditioning and the appearance of fuller, longer lashes, this is a great one to have on your radar.

The Ordinary Multi-Peptide Lash and Brow Serum: The Budget-Friendly Pick

Curious about lash serums but don’t want to invest too much? The Ordinary Multi-Peptide Lash and Brow Serum is a great place to start, especially if you want to try one without making a big commitment.

The lightweight, water-based formula contains four peptide complexes, alongside caffeine and plant extracts, and can be used on both lashes and brows. It’s also vegan, oil-free, silicone-free and alcohol-free. Using it twice daily, you may notice improvements in volume and overall lash and brow appearance in as little as four weeks with consistent use.

Why We Love It: It’s simple, affordable and versatile, a particularly good option if you’re new to lash serums or want one product that works for both lashes and brows.

How to Get the Most From Your Lash Serum

A lash serum only works as part of your routine if you actually remember to use it. Remember to keep things simple:

- Start with clean skin. Remove makeup, mascara and any residue before applying your serum.

- Follow the instructions. Different formulas have different application and frequency recommendations, so don’t assume more product means better results.

- Apply precisely. Most lash serums are designed to be applied to the upper lash line rather than coated over the entire lash.

- Be consistent. Whether your chosen serum is designed for once- or twice-daily use, regular application is key.

- Give it time. Lash serums aren’t an overnight fix. Results vary between products and people, so stick with your routine rather than expecting an instant transformation.

- Pay attention to your eyes. If you experience irritation or an unwanted reaction, stop using the product and follow the brand’s safety advice.
