The best eyelash growth serums for conditioning and enhancing your eyelashes

9 best eyelash growth serums that actually work to lengthen natural lashes

Posted by for Beauty

No doubt you’ll have heard about eyelash growth serums like RevitaLash and RapidLash, but do they really work? We review them all to find out. 

While the want for longer, defined lashes continues, we’re all looking for ways to boost our own natural lashes. Because, whilst lengthening mascaras and eyelash curlers are helpful, they’re not a ‘wake-up and go’ option. They’re a ‘make sure to remember to do’ option. Very different.  

This explains the popularity of semi-permanent lash extensions and why it continues to skyrocket as we shift to a ‘my lashes but better’ approach. Over the past year, there’s been a 110% increase in Google searches for “best lash growth serum” in the UK and it’s showing no signs of slowing down. 

There’s also a growing demand for lash-lifting treatments and growth-enhancing lash serums to boost what nature gave us. Tempted? Stylist’s digital writer, Megan Murray can vouch for the results you can get from the lash-lifting treatment, LVL

In-salon lash lifts (Nouveau Lashes’ LVL is the most popular) work by straightening natural lashes at the very root which, alongside a tint, gives the illusion of extra length and volume. They won’t damage lashes and don’t require any upkeep, unlike extensions. The results (above) can be pretty phenomenal. 

Of course, getting an in-salon lash treatment might not be possible but lash growth serums are the perfect at-home solution. These serums are designed to be applied daily, using ingredients that actively stimulate growth.

Then there are lash conditioning serums – formulas that work more like hair conditioners. They won’t necessarily lengthen lashes but help to keep things healthy, preventing brittleness and breakage which in turn can encourage them to become thicker and longer.

Dermatologist Justine Hextall advises looking out for the same hydrating ingredients you’d find in good skincare. “Hyaluronic acid and glycerine are humectants that hydrate skin and lashes by attracting and holding on to water,” she explains. “Biotin is important for healthy keratin to strengthen lashes, and plays a role in the growth of thicker hair. And vitamins B5 and B6 also promote healthy hair because your body uses these nutrients to nourish your hair follicles,” Hextall adds.

The key to making them work? Be patient. Our lashes have a cycle of up to 90 days so you may not see full results until then and be consistent, no skipping days. Before applying, make sure your lash-line is free from oily make-up removers or cleanser residue that could create a barrier.

Prefer a formula boasting cutting-edge technology and proven ingredients? We’ve rounded up the best lash-boosting products on the market.

(Quick reminder: if you find that your skin or eye area doesn’t take well to the formula, take a few days off to identify if the lash growth serum or lash conditioner is the culprit. If it is, leave it to the side and revert back to manual lash enhancers (mascaras, curlers or a lash lift). An allergic reaction is a sign to pull back, not push on.)

The best lash growth serums and lash conditioning serums

  • Best for ultimate length: RevitaLash Cosmetics RevitaLash Advanced

    Loved by beauty industry experts, Meghan Markle and even one of our contributors (read the detailed review here), RevitaLash is considered the gold standard in lash growth serums. Commit to just one speedy swipe each night and you’ll see a visible difference in two to three weeks. It works by slightly slowing your lashes’ growth cycle so, while they’re still fall out eventually as is required for healthy eyes, they’ll stay put that little bit longer – allowing them to reach extra lengths.

    Masterminded 11 years ago by a doctor who wanted to help his wife suffering from lash loss after cancer, the company is still family-run and dedicates substantial time and funds towards breast cancer research and awareness.

  • Best mid-priced lash growth serum: RapidLash Eyelash Enhancing Serum

    This is another industry favourite. Again, it harnesses proven, growth-stimulating ingredients although they’re slightly different to RevitaLash and testers have found the results to be a little less dramatic. Still, you’ll get a marked increase in length and thickness that’ll be noticeable, not just by you, but others, too.

    Most lash serums are for nightly use but this gem is to be slicked on morning and night. It’s worth the extra pre-make-up step, though. After leaving it to dry for 60 seconds, you’ll notice your mascara glides on more smoothly and lashes appear a little fuller and more defined. Over time, castor oil, vitamin b5, hyaluronic acid and Filloxane (the same ingredient found in L’Oreal Paris’ best-selling hair thickening shampoo) will get to work.
