Between extensions, tints, lifts and manually applying false lashes every day, those looking to lengthen, define, and thicken their lash lines—without mascara—have plenty of avenues to explore. But the idea of holding onto that fluttery lash look permanently is much more appealing to many, which explains why eyelash growth serums continue to dominate in popularity.

Truthfully, though, finding the best eyelash growth serum for you starts with understanding the caveats of the category. The only product on the market that is truly FDA-approved to promote eyelash growth is a prescription drug called Latisse.

According to Dr. Annie Chiu, a board-certified dermatologist at the Derm Institute, Latisse is made with a prostaglandin analog called bimatoprost.

“Latisse works by lengthening the eyelash growth phase, as well as the number of hairs produced,” Dr. Chiu said. When used daily along the upper lash line, Latisse typically results in longer, thicker and darker eyelashes. As for many of the over-the-counter lash serums out there, they probably won’t give you growth benefits. It’s worth noting that Dr. Chiu said that if they do not contain a prostaglandin analog, they will “likely have a limited effect in the increase of actual growth length, or darkening of lashes.” So, you’ll want to keep that in mind when you read product labels.

However, what most lash serums can do is help improve lash health and prevent breakage, therefore improving your eyelashes overall appearance. That’s another reason you’ll see lash serums typically described as enhancing, conditioning, or nourishing in their names. These products commonly contain ingredients such as biotin, panthenol, peptides and keratin, among other extracts. Check out this roundup of seven of the most popular lash serums out now.


As far as lash serums go, RevitaLASH is a cult-favorite buy. The formula specifically works to improve lash flexibility, prevent breaking, and boost moisture, but reviewers claim seeing noticeable and impressive results in length and volume, too. To get the most desirable effects, the brand recommends being consistent with your routine and applying the serum once a day.


A clean and vegan formula, LASHFOOD’s lash serum is made without silicone, synthetic fragrances, synthetic dyes, mineral oils, GMOs and more. Its formula is meant to deliver the appearance of longer lashes by strengthening, conditioning, and soothing through ingredients like lavender water, soy protein, and an herb extract-based Phyto-Medic Complex.


This affordable brush-on serum utilizes a blend of lash-loving ingredients like hyaluronic acid and the amino acid arginine. It’s said to promote thicker-looking eyelashes and help prevent lash loss while removing makeup. Avoiding aggressively rubbing your eyes while taking off mascara, eyeshadow, and eyeliner can also help with the latter.


A multitasking, 2-in-1 product, this serum treats both the eyelashes and eyebrows. The formula’s star ingredient is hemp-derived cannabis seed extract, meant to condition those tiny, delicate hairs. Many Sephora reviewers note it’s non-irritating and claim it’s been beneficial for eyebrow fullness.


Another product that can be used both on the eyelashes and the eyebrows, Dr. Lara Devgan’s formula uses ingredients such as vitamin b5 and clover flower extract to help improve the appearance of lash and brow hairs. While it’s scored a plethora of five-star reviews on Sephora, the brand notes it needs to be used consistently for five months to see full results.


What sets this lash serum apart from all the rest is that it’s actually an eye serum, too. This brightening and firming formula is designed to target fine lines and dark circles.

To further promote a well-rested look, it can be applied along the lash line via the cooling applicator, as well. The brand says it will strengthen and improve the appearance of lashes.


Peter Thomas Roth’s popular lash serum claims to help improve the eyelashes’ overall natural appearance — targeting fullness and length — through a series of conditioning and moisturizing ingredients like an 11% peptide complex and biotin.
