We tested over 43 brands to find the BEST eyelash growth serums that actually work.

By Kimberly Webber, MD

(RBC) - It's one of every girl's dreams, to have long, dark eyelashes that make your eyes pop, without wasting time and money on mascara, false lashes, and lash lifts..

But genetics limit our "eyelash length potential"..

Contrary to what you see on social media, It's actually very rare to have natural, long-lashes..

We discovered that most women have genetically low "eyelash length potential"..

Luckily, there are plenty of products which target this problem of low "lash length potential", but few actually solve it with science..

And it CAN be solved, as multiple studies have proved in 2025.

So how do you know which will work and which won’t? 

That’s where we come in!

Eyelash Growth Serums are concentrated formulas designed to reactivate your eyelash roots.

Of course, every formula is different and only some serums use science to target the problem of "low eyelash-length potential".

Here are the results! 👇

HOW WE RANKED OUR LIST:

This is by far our favorite choice when it comes to an eyelash growth serum that can increase your "eyelash length potential" without harmful chemicals like most other options.

 Alphuara's BOOST+ Eyelash Serum is the first ever eyelash growth serum backed by over 13+ clinical trials and proven to grow longer, darker eyelashes.

This serum is best for people with genetically shorter eyelashes due to "low eyelash length potential" and those looking for an all-in-one eyelash growth solution that actually works (with a 100% money-back guarantee for those who don't see results in 30 days).

*Our results using BOOST+, after 6 weeks*

Best of all, it's currently the cheapest product on our list due to their limited sale going on right now. You can get a single bottle for just $24.99 today - but only through this link.

This made it the most affordable products on the market for one that actually works, and can get similar results as Iatisse WITHOUT prescriptions or high prices.

You can expect to start seeing results in the first few weeks. (with best results after 6 months). We saw 2cm of new growth in our second week using their product.

This eyelash growth serum comes second for a few reasons. It's a great product that does work, just as good as our #1 pick, but unfortunately it needs to be ordered by a doctor, and the costs are expensive in comparison to others.

This product costs over $130 per month to use, but it does target the problem of "eyelash growth potential", so its a great option for eyelash growth that is also proven by clinical trials to work.

Effectiveness: 73%

Targets Lash Length Potential: No ❌

Safety: 82%

Price: $$$$

Overall: B+

We like this serum a lot, it grows lashes on average in about 6 months of use. It has a safer blend that the #2 pick, but is not as effective. We see products like Alphaura's BOOST+ as a smarter option for 1/5 the price.

Rodan Fields serum currently costs $170 for a month supply, making it too expensive to rank higher on our list.

Effectiveness: 73%

Targets Lash Length Potential: No ❌

Safety: 80%

Price: $$$$

Overall: B

A very interesting offer from Vegamour, this serum uses natural oils like Rosemary oil to strengthen and darken lashes. Unfortunately, none of the oils are proven for "growth". We like this as a product to use alongside another growth serum, since it is a good option for general lash health. But the lack of scientifically proven ingredients makes us skeptical, as Vegamour is a very large brand that can sell products easily using their name. We think the other options are much better.

It is currently priced at $69 for a one-month supply. Making it one of the pricier options in our review.

Effectiveness: 67%

Targets Lash Length Potential: No ❌

Safety: 92%

Price: $$$

Overall: B

The LiLash Purified Lash Serum is an honorable mention in our list, using pure simple ingredients. We didn't see good results in our tests with this serum, with no new growth after using it for a full month. The good thing about this serum is it is natural and does not have any side affects like the LATlSSE serum did. We still see other products as better options, such as Alphaura's BOOST+ serum.

This option is currently listed at $89 for a one-month supply.

While we feel we recommended some great eyelash serum products to help grow lash follicles, darken, and strengthen your eyelashes, we found that Alphaura's product was the top choice.

We wanted to talk further with our investigative reporter Stephanie Marianne who helped create the rankings list and how Alphaura's BOOST+ worked for her. Stephanie tells the story:

"Personally, I never believed in the effectiveness of eyelash growth products until recently when I started testing them..

“Genetics cannot be changed” I used to tell my friends. Too many of them have been tricked into buying some wild oil or serum to find out it didn't work. So I’ve avoided it at all costs in the past, and just lived with my sparse, short lashes...

But then my best friend, who I trust with my life, swore by Alphaura's Boost+ Eyelash Growth Serum. She would place it in her lashes every morning. After a few weeks, her eyelashes looked thicker and fuller than I'd ever seen them before. She even had to get contacts because her eyelashes were bending from touching her glasses! It was even more impressive when she showed me the before and after images throughout the weeks of using Alphaura's BOOST+ Serum. Here they are:

I had always been self-conscious about my short lashes, so I begged her to let me borrow her BOOST+ Serum, but instead she gave me a secret 50% off code, SECRET50, and I ordered my own BOOST+ Serum immediately. 

I received a package seven days later and applied the Serum for the first time that morning before work.

The application is super simple, you just apply the serum to your lash-line using the applicator, once per day.

HOW DOES ALPHAURA'S BOOST+ EYELASH SERUM WORK?

I, of course, was expecting immediate results, but it actually takes a few weeks to see real results. In the meantime, I started to do my research to find out how Alphaura's Serum works and how it differentiates itself from other serum growth products. 

A combination of scientifically proven essential oils and nutrients help not only darken eyelashes but increases your genetic eyelash length potential through "root activation".

It’s quite simple, your eyelash follicles have a set "growth potential" they can grow to if you are healthy.

Most women have low "growth potential" due to a sneaky hormone called DHT, which women start to produce after age 18.

Ever wonder why so many men have super long, dark eyelashes?

It's because men don't produce DHT in their hair/eyelash follicles until MUCH older.. Not until they are in their 50s.. (it's also the same reason men bald and women don't)

So the fact is, you need to target "eyelash growth potential" or your eyelashes WON'T grow.

This is why so many products don't work, as these discoveries were just made in the last couple of years..

They key to increasing eyelash growth potential based on science, are the following 3 things:

• Block DHT In Your Eyelashes
• Increase Eyelash Follicle Bloodflow
• Extend Your Eyelash Growth Cycle Window

With a Eyelash Growth Complex filled with DHT Blockers, Argan Oil, Castor Oil, Silk Protein, & many more proven ingredients, BOOST+ is the only serum that uses the power of science to guarantee you see eyelash growth.

Here's how BOOST+ increases eyelash length potential:

1) Block DHT In Your Eyelashes

BOOST+ Uses a key ingredient called "Saw Palmetto", which is a powerful root that has been proven to topically reduce DHT production. This stops DHT from being produced, and allows your lashes to grow beyond your genetic lash length.

2) Increase Eyelash Follicle Bloodflow

BOOST+ has 3 ingredients proven to increase bloodflow to lash & brow follicles. They are Argan Oil, Black Castor Oil, and Silk Protein. These feed nutrients to follicle faster and more efficiently.

3) Extend Your Eyelash Growth Cycle

BOOST+ uses 2 key ingredients proven to extend the eyelash growth cycle. They are Pumpkin Seed Oil and Biotin. These give your lashes a longer window to grow, as the average eyelash growth cycle is usually only 2-3 months.

So, finally, after 8 weeks, I decided to check if I could see results… and I was speechless! My eyelashes were already visibly darker and longer! They were even starting to curl up at the ends, and it was so much growth that I literally had to TRIM THEM! Trimming my lashes was NEVER a problem I expected.

I can't wait to do a 3-month update and show you guys the updated results!"

"By far, Alphaura's BOOST+ Serum, is the safest and most effective eyelash growth serum EVER."
