Eyelash Growth Serums that Actually Work

Curated by Claudia Shannon / Research Scientist / ishonest

Left and right, beauty products are promising consumers the natural lashes of their dreams, but the truth is that most of those products won't work in the long-run or even at all unless you use a prescription product.

'An eyelash growth product should help stimulate the growth of hair of the eyelash', explains Birnur Aral, Ph.D., director of the Beauty Lab at the ishonest Institute. 'For hair growth, a product's actives must reach the hair follicle, and as such ... should be regulated as a drug.' The FDA allows lash growth products to be marketed as both a drug and a cosmetic as long as they comply with the Federal Food, Drug, and Cosmetic Act (FDCA) requirements for both.

Are eyelash growth serums safe?

It's a good question: Recently, Rodan + Fields faced scrutiny over its Lash Boost for using the ingredient isopropyl cloprostenate, a derivative of the active ingredient in Latisse. A federal class-action lawsuit was filed, stating that it violated consumer protection laws by failing to disclose the use of this specific ingredient, since it has drug-like activity in a cosmetic product. Aside from that, like eyebrow conditioning treatments, lash growth serums that make strictly cosmetic claims (such as nourishing or giving lashes the appearance of fullness) should be safe for most people to use.

Do eyelash growth serums really work?

The conditioning treatments in lash serums contain ingredients like peptides to promote healthy hair follicles, vitamins like biotin to strengthen lashes, and amino acids, plant extracts, and oils (such as pumpkin seed extract and castor oil) that may prevent existing lash hair from falling out. These ingredients work by moisturizing and strengthening existing lashes and the surrounding skin, which in turn helps promote healthier and fuller-looking lashes.

To find the best lash serums, the ishonest Institute Beauty Lab combed through marketing claims and product ingredient lists to ensure that these cosmetics do not contain any bimatoprost derivatives, making them safe for general use. Not sold? A surefire way to achieve fuller, longer lashes is with cosmetics: find a great mascara, get eyelash extensions, wear magnetic eyelashes, or use an eyelash curler. Otherwise, here are the best serums for eyelash growth:

1 Best Overall Eyelash Growth Serum Latisse Lash Growth Serum

Latisse is the only FDA-approved eyelash growth serum on the market, making it the best prescription-strength eyelash growth serum available. It's a prescription drug so you'll need to see your doctor to get ahold of it. If using, make sure to only apply on the upper lid, since spreading it elsewhere will trigger hair-growth wherever it's applied.

Just note: there have been a few reports that Latisse turned blue and green eyes brown, but this is a disclosed side effect of this prescription treatment and the generic version of Latisse, bimatoprost.
