Naturally fluttery lashes can be yours with the best eyelash grower serums on the market. These strengthening and growth-boosting products are sweeping the beauty industry and it seems like every brand is bringing out a version of a fortifying lash serum. 

If your lashes are sparse, short, and straight, even the best mascara might not be enough to achieve the flutter you desire. If you want to know how to grow eyelashes naturally, then trying an eyelash grower serum is probably the way to go. "When faced with stress, menopause symptoms due to declining estrogen levels, poor diet, topical stresses such as perming, tinting and lash extensions, the lash will not survive all three phases of the hair cycle,” explains Natalia Ferrara, Global Educator at Revitalash Cosmetics. “The best eyelash grower serum provides a healthy environment for your lashes to breathe and thrive by combating biological and topical stressors. This allows for your lashes to survive all three phases of your hair cycle.” 

With so many eyelash growth serums now on the market with vastly varying prices, it can be tricky to know where to turn. So our expert tester put the latest and greatest on trial to bring you our pick of the best eyelash grower serums for natural flutter. 

How do the best eyelash grower serums work?

All eyelash serums work by nourishing the roots of the lashes with active ingredients like peptides, Vitamin E, castor oil, or hyaluronic acid to support the growth cycle. “It takes three stages for your eyelashes to essentially replenish in their hair cycle: anagen-growth phase; catagen-transition phase and telogen-resting phase," explains Natalia. "During the anagen phase (lasting 30-45 days) only 40% of your upper lashes and 15% of your lower lashes are growing at any one time. It can take four to eight weeks to fully replace an eyelash. Lash pigment and follicle shrinkage happen in the catagen phase, and the lash sits in the telogen phase for over 100 days before the lash falls out and a new one is replaced.”

A powerful eyelash grower serum should support the lashes within the anagen phase to encourage growth. But you won’t be able to see a change overnight, average eyelash growth cycles are around three months, so it will take a little while to notice a change.

How long do eyelash grower serums take to work?

“There’s no one-size-fits-all answer to this question,” says Natalia. “Some people see results in terms of improved lash condition and overall lash shine and flexibility in as little as a week, but for the full effect, it’s usually longer. Generally, we say three to six weeks to capitalize on the anagen phase of the hair cycle.”

To see results as soon as possible, Natalia suggests applying your eyelash serum on a regular basis, “It’s important to apply the serum once a day for at least three months to achieve full lash benefits.” As with much of our hair and skincare routine, consistency is everything. Most of these products are meant to be applied at night but skipping a few days in between applications can lessen their effectiveness.

As this lash serum is full of hydrating ingredients like glycerin and panthenol, it's brilliant for dry, sparse lashes in need of a pick-me-up. Its hypo-allergenic formula is also great for sensitive eyes that get irritated easily. 

The more affordable price tag is a great plus and we did find it to be beneficial to the lashes, leaving them longer, fuller and darker. And while the formula isn't quite as advanced as some other eyelash grower serums on the market, it does make a great daily lash treatment if your eyes sting when using other ones.

Boasting the chicest packaging of the bunch, Lancôme's eyelash serum is formulated with a trio of powerhouse ingredients including their kerasolution complex (a combination of 3 amino acids) plus hyaluronic acid and cica.

The serum feels a little bit thicker than the others, almost like a deeply moisturising lash mask and is brilliant for sparse lashes or lashes that shed a lot more than usual. It's definitely one to try if your lashes need a deep conditioning treatment and after a few weeks use, we definitely saw some new lash growth.

Easy to apply to the lashes in a spill-proof brush applicator, it's one to buy if you're wanting to give lash serums a go but feel a little sceptical about splashing the cash. 

It's affordable, effective and great for improving the quality of dry, dehydrated lashes. We suggest applying once a day, morning or evening, for at least three weeks to see the best results.

Reasons to buy
+Vegan, cruelty-free formula+Easy to use

The conditioning pumpkin seed extract in Sweed's lash serum is very effective on dry, thin lashes that need some TLC. If you're an avid lash extension wearer, try giving lashes a break and applying this for a few weeks instead. Our tester definitely saw an improvement to the quality and density of their lashes. 

All of Sweed's products seem to fly off the shelves (they have brilliant individual and cluster false lashes) and we can see why this product has been so popular too. It is a pricier option but the vegan, cruelty-free ingredients mean you can buy with ethical confidence. 

Shiseido Full Lash Serum

8. Shiseido Full Lash Serum

Best for lashes & brows

Specifications
RRP: $36/£42
Key ingredients : Arginine, jujuba fruit extract
Reasons to buy
+Great for lashes & brows+Easy to use+Thickens hairs
Reasons to avoid
-Pricey-Doe foot applicator

One of the mid-range options, this lash serum can actually work on brows as well as eyelashes. Ingredients like arginine and jujuba fruit extract condition and strengthen the lashes and do a fab job of making them look fuller. 

The drawback (or plus, for some) is the doe foot applicator. It may not be the most convenient way of applying lash serum as the brand recommend wiping the wand for hygiene after applying. To us, that seems like a waste of an expensive product.

Our tester did love the formula though and found it comfortable to wear with no irritation so, if you can get past the applicator, this one is your winner for thicker lashes.

The formula contains a lovely blend of peptides, proteins, vitamins, bamboo extract and castor oil which does nourish the lashes and support healthy growth but it's not the most high-tech on offer, though, for the price, it's a great lash serum to buy. 

Rodial Lash and Brow Booster Serum

10. Rodial Lash and Brow Booster Serum

Specifications

Reasons to buy

-Pricey

As the name suggests, this lash and brow serum is great for giving hairs a little bit of oomph. With a mix of Vitamin B5, caster oil, hyaluronic acid and proteins, this product worked wonders on our tester's lashes, in time turning them from stubby and poker straight to long with a natural curl. 

If you have straight lashes, we can't recommend this lash serum enough but as it's a little more expensive than others on the market, it's definitely a beauty investment.

Best for fast results

Specifications
RRP: $49.99/£40
Key ingredients: Hexatein 1 Complex
Reasons to buy
+Effective on lash growth+Easy to use+Sophisticated formula
Reasons to avoid
-Pricey

If your lashes are seemingly beyond repair, this is the serum to go for. Its innovative Hexatein 1 Complex contains a mix of lash-boosting peptides and proteins that work together to restore healthy lash growth. 

It comes in at an average price point on the market, meaning it is a little bit on the pricey side, but you do get a sophisticated formula in exchange for that. Our tester loved the formula but did find it a little irritating on the eyes so if your eyes are a little sensitive, you may want to try something else.
