We all condition our hair, so why are we neglecting our eyelashes? If you want your lashes to grow longer, look thicker, and appear more lush all around—sans extensions—you need to add a lash serum to your nightly skincare routine. And according to LASHFOOD’s Faith Kim, any lash serum falls into one of two categories.

“There are chemical bases—prostaglandin analog—and then plant-based ones,” says the clean beauty brand’s co-founder and president. “Prostaglandin is the active found in chemical enhancers. Latisse uses a prostaglandin analog called bimatoprost, which is a glaucoma drug.” Alternatively, you can look for serums made with Myristoyl Pentapeptide-17 (a peptide), biotin, arginine, or bamboo. The one catch? For real results, you do have to remember to apply the lash serum every single day. Ahead, 15 of our tried-and-true favorites.

How long does it take to see results from lash serums?

Although results vary from product to product, many users report seeing a difference in their lashes in as little as four weeks. The catch? Consistency is key, so don't skip an application.

Where do I apply lash serums?

It may seem intuitive to apply a lash serum on, well, your lashes, but many formulas recommend applying to the base of your lashes, like eyeliner. Of course, read and follow the instructions thoroughly as formulas vary.
