Between lash extensions, tints, lifts and manually applying false lashes every day, those looking to lengthen, define, and thicken their eyelashes without using mascara have plenty of avenues to explore. Most are temporary solutions though. Technically speaking, the prescription drug Latisse is the only FDA-approved product to truly promote lash growth. But for a more approachable alternative, over-the-counter lash serums can help improve eyelash health and prevent breakage, enhancing their overall appearance as result.

Ingredients like biotin, keratin and peptides, among other extracts, are commonly found in these products to help enhance, condition or nourish lashes. Below, find eight of the best eyelash serums that check the box for all of the above.

Best Eyelash Serum For Thicker Lashes
Enriched with arginine, an amino acid that helps restore the condition of hair, this serum helps lashes grow denser and thicker in practically no time. Ok, it may take eight to 16 weeks (according to a consumer survey of 100 women), but good things do take time. An added bonus? The formula can be used on your brows too.
Best Eyelash Serum For Sensitive Eyes
If you’re looking for a clean lash serum that’s free of irritants, hormones and carcinogens, then you’ll love this plant-based, science-backed formula. It’s spiked with naturally derived, safe-to-use ingredients like red clover and mung bean that promote length and thickness.
Best Eyelash Serum For Damaged Lashes
Just as the name suggests, this serum gives lashes a revitalizing boost using a blend of amino acids that helps condition damaged hair follicles. With an ultra-precise brush applicator, you can easily target any hard-to-reach areas (we’re looking at you, inner eye corners). For best results, apply the formula onto the lash line and sweep it from root to tip.
Best Eyelash Serum Mascara
Kill two birds with one wand with this hybrid mascara. Not only does it instantly elongate lashes, it also makes them stronger over time thanks to its green tea extract-infused formula.
Best Eyelash Serum for Brittle Lashes
As far as lash serums go, RevitaLASH is a cult-favorite buy. The formula specifically works to improve lash flexibility, prevent breaking and boosting moisture, but reviewers claim 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.
Best Drugstore Eyelash Serum
This affordable brush-on serum uses 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. You can also help with the latter by going easy on your eyes during mascara, eyeshadow and eyeliner removal.
Best Hemp-Based Eyelash Serum
A multitasking, two-in-one product, this serum treats both the eyelashes and eyebrows. The formula’s star ingredient is hemp-derived cannabis seed extract, which helps condition those tiny, delicate hairs. Many Sephora reviewers note that it’s non-irritating and claim how beneficial it is for eyebrow fullness.
Best Multitasking Eye Lash Serum
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 that it needs to be used consistently for five months to see full results.
