lash serums

Not all of us are blessed with long, luscious eyelashes. Whether your natural lashes are short and sparse or eyelash extensions have left you feeling a little naked around your eyes, some of us could use a little boost on our fringe.

Talk to any lash obsessive and they'll tell you that a lash serum can save the day -- it just comes down to sifting through all the different brands, formulas and price points. Some products promote natural lash growth by adding volume or length, while others primarily condition the lashes you already have and help prevent breakage. Many do both -- and can even be used to amp up your eyebrows.

So what makes a good, effective eyelash serum? The ones we love contain hardworking ingredients like biotin and hyaluronic acid, come with an applicator brush for precise application and, ideally, are available online and over the counter. (Popular brand Latisse -- with active ingredient isopropyl cloprostenate -- has been proven to be incredibly effective but requires a prescription.)

One piece of advice: Don't expect longer lashes overnight. If you choose to introduce any of these products to your beauty routine, wait at least a couple of weeks before you expect to start to see results. In the meantime, there's always mascara and eyelash curlers.

Below, the eyelash growth serums we have our eyes on right now.


This Vegamour vegaLASH Volumizing Serum is 100% cruelty-free and vegan. This lash enhancer doesn't have any carcinogens or known hormones in its unique formula. vegaLASH has been formulated to provide fuller, longer and thicker lashes within the first 30 days of use.

Milk Makeup

Clean beauty brand Milk Makeup hit a home run with its lash serum, which uses natural ingredients like cannabis seed extract, plant peptides and quinoa to nurture lashes. This is a vegan option to help achieve the look of fuller lashes. And it smells great.

Lash Enhancing Serum

Neulash's powerful lash serum uses sodium hyaluronate to drench your lashes in moisture, plus amino acids, biotin and panthenol to fortify. Try using this nightly until you get the lash growth you're looking for, then switch to applying every other day.
