Best eyelash serums for healthier, stronger lashes

Your lashes will be back to their naturally voluminous ways in a matter of weeks.

Best eyelash serums

Updated on

It’s normal to lose some eyelashes as you get older but if the appearance of a more dense lash line is getting you down, the best eyelash serums can help to rejuvenate your lashes. Lash growth serums are packed full of ingredients that will stimulate hair growth in hair follicles. They encourage new lashes to come through while also nourishing and strengthening existing lashes. If you’re after more naturally voluminous and healthy eyelashes, a lash serum will certainly help.

Just like our hair naturally starts to thin during the ageing process, the same happens to our eyelashes. If you’re used to having thick, luscious lashes, this can give your confidence a knock. Unfortunately, it can't be solved with a coat of good quality mascara as that may only highlight gaps more. You can apply false lashes but if you prefer a more natural look, the best lash serums are designed to help add fullness back to your lash line. They'll also prevent further breakages over time. Ageing can also cause lashes to become brittle so a lash serum will make them more moisturised and hydrated.

Using a lash serum isn’t a quick win. It will require a couple of weeks and even months of continuous use for you to start seeing results. Many of the best eyelash serums are directed to be used nightly so they can work their magic overnight. This way you can easily incorporate it into your evening skincare routine. Just apply the serum around the same time you’ve added your under-eye cream and you'll be good to go.

Whether your goal is for longer, thicker lashes or to make your lashes stronger and softer, we’ve rounded up all the best eyelash serums to add some va-va-voom back to your natural lash line. With consistent use, you’ll soon start to see your lashes back to their naturally voluminous and healthy ways.

It might have been one of the first eyelash serums on the market when it launched back in 2008, but the RapidLash Eyelash Enhancing Serum is still the best in our opinion, even 16 years later. It contains essential proteins and vitamins as well as moisturising and rejuvenating ingredients to get your lashes looking and feeling in tip-top condition in just eight weeks of daily application.

Customer review: "I have used various lash growth serums over the years and keep coming back to this one because it's the one that actually works! You need to be patient and apply every night, but I do see results in the form of thicker, fuller natural lashes. With age, I've found my lower lashes have become more sparse, and RapidLash seems to be the only thing that has kick-started their growth again. I do advise following the application instructions to the letter, especially when being careful how much you apply as it can cause eye irritation if you apply too much. Use a very light hand when applying as less truly is more with this product."

Pros

  • Conditioning and moisturising formula
  • Makes lashes appear longer and thicker
  • Paraben-free formula

Cons

  • Takes up to eight weeks to see results

Best budget eyelash serum

The Ordinary Multi-Peptide Lash & Brow SerumBoots

At just over £14, The Ordinary Multi-Peptide Lash & Brow Serum is the lowest price serum on our list but just because it's cheaper than others on our list, doesn't mean it doesn't perform.

It utilises 11 active ingredients, including four peptide complexes to ensure your lashes are nourished and protected while also enhancing their overall appearance and density.

It's a clear serum that acts as a great nourishing base for your everyday eye look. Just apply it along your lash line at night and in the morning, add mascara from root to tip for natural-looking, defined lashes.

Customer review: "I was dubious that this product would work but as my lashes had become really sparse & gappy & I had even started looking for mascaras to volumise, which i'd never needed before, but they had got so bad that I decided to give the serum a go & I'm sooo glad I did, it really works !!! I'm one of the biggest cynic regarding beauty products and I've used a lot in my time! but this, I will definitely be buying more of & it's going to be a firm staple in my beauty routine. Not only are my lashes fuller but they are also much longer. I was even in the middle of buying some new glasses & the optician had to adjust my glasses as he commented that my eyelashes were now touching my lenses! I also now only need to add the merest slick of mascara & most days I go without which is a first for me. You need to let the product have time to work, don't expect a difference in a week & if there is none give up..... I've been using it since just before Christmas, so 4 months & I now have well-established long thick lashes. I took before & after pictures & the difference is clearly visible. I use it once a day before I go to bed & I'm just coming to the end of my first bottle so great value for money..."

  • Makes lashes fuller, thicker and darker
  • Suitable for sensitive skin

With over 7,000 reviews and an average rating of 4.6, the Wewell Eyelash Growth Serum is much-loved by customers on Amazon. Its ingredients are designed to work deep into the lash follicles to stimulate lash growth and nourish them from the root right up to the tip. The formula promises to increase lash growth and thickness while also being gentle and soothing to the skin around your eye area.

Customer review: "As a woman in my fifties, my eyelashes are now alot sparker, so I was looking for an eyelash serum to help nourish and grow them. This little beauty is absolute amazing, I have been using it for a few months now once or twice a week and it has strengthened and grown my lashes amazingly well. The first pic is with no mascara on and the second pic is just with a very light coating of mascara on. I really can't recommend this enough if you have short lashes, have gone through/going through the menopause or have long covid or any thing else and your eyelashes have suffered and you just want to have a bit of length again. Also it doesn't sting your eyes either and you only need to use a small amount as well so a little goes a long way."

Pros

  • Works from root to tip
  • Gentle and soothing formulation
  • Leaves lashes looking full and longer in a matter of weeks

Cons

  • A handful of reviewers reported irritation

Best lash serum UK FAQs

What is the best eyelash growth serum?

The ideal eyelash serum for you will depend on the end goals for your lashes, your preferences when it comes to what's in formulations, and your budget. Still, in our opinion, we think the best lash growth serum is the RapidLash Eyelash Enhancing Serum. One of the original eyelash serums on the market, it is proven to deliver results. It will leave your lashes looking fuller and longer in a matter of weeks while also moisturising and rejuvenating them to improve their overall condition.

Do eyelash serums actually work?

We understand that some of you may be sceptical about whether eyelash serums actually work and from our research, a lot of the reviews on products were a mixed bag. Lash serums do require commitment and time to work but they're worth putting into your make-up and skincare bag.
You need to use them religiously every day and apply them to the instructions of your chosen serum. Many serums just need to be applied from root to tip on each lash in the evenings whereas others may need to be applied twice daily. It may take a while for you to notice the results but with a little perseverance, you’ll be rewarded with fuller, stronger lashes in time.

How long does lash serum take to work?

You may be disheartened to not see results straight away but all the best lash serums take a few weeks for them to work their magic. A handful of eyelash serums say they take at least four weeks for you to start noticing the difference. However, most say to wait at least eight weeks to experience results.

What ingredients should you look for in an eyelash serum?

When looking for a serum to use on your lashes, you'll want to look for one that has ingredients that will help your lashes grow while nourishing and strengthening them. Here are some of the most common ingredients:
Peptides:
Peptides, which are a short chain of amino acids that are crucial for forming collagen and keratin, help nourish and condition lashes. Having Peptides present in any lash serums will prevent breakage and boost moisture levels as they work directly at the hair follicle.
Vitamins and antioxidants:
Look for a serum that’s rich in Vitamin E, Vitamin C and other antioxidants. These are designed to protect lashes from damage and contribute to their overall health and appearance. Vitamin B7 (biotin) and Vitamin B5 (panthenol) are also commonly used in eyelash serums, as well as hair and skincare products. Biotin will help strengthen and thicken your lashes while panthenol will help to moisturise and condition lashes to aid with reducing breakages.
Hyaluronic acid:
If you feel like your lashes need some added moisture, look for a lash serum that contains hyaluronic acid as it is a hydrating ingredient.
