Our tester liked the applicator on this popular lash serum, and while she felt that her lashes were slightly stronger after using it, she didn’t notice much improvement in terms of length or volume. Although the pump applicator might be hard to control (it can dispense too much product), the results make using the serum well worth the inconvenience. After the full ten-week testing period, we saw a real improvement in the strength and fullness of our lashes. We also love that the formula helps reduce the number of lashes that fall out during makeup removal.

Peptides: Jas Imani, a New York City-based licensed esthetician and certified Yumi Lash esthetician, recommends looking for formulas that contain peptides, which she says are great for fortifying lash hair and helping lashes grow stronger. Peptides are also great for nourishing lashes that are brittle and frail, so consider them a must if you’ve been too rough with mascara removal or wear waterproof formulas on the regular. GrandeLASH-MD Lash Enhancing Serum is an excellent choice that contains peptides. While this all natural eyelash enhancing serum was easy to apply and non-irritating, our tester saw no improvement in the appearance of her eyelashes. Velour Lashes Long & Strong Lash Serum Have you heard of lash conditioning serum? Commercial serums work to strengthen and enhance your lashes and brows, making them shinier and fuller looking. And, no surprise, they can be super pricey! Also not a surprise, you can make a super-easy version at home with just a few simple ingredients.Start by gently cleansing your eye area and removing all makeup, sunscreen, and other skincare residues. Gently pat your skin dry, and make sure it's entirely dry before beginning. Using the applicator wand, carefully glide the brush along your upper lash line to apply a thin layer of serum—almost like applying liquid eyeliner. Repeat the process on the lower lash line, and wait for the serum to dry completely before applying anything else.

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. Carefully following the directions is crucial when using a lash growth serum. Some formulas are meant to be used daily, while others might call for twice-daily use.Caitlyn Martyn is a commerce writer on staff at Byrdie, where she covers beauty and style. She gathered insights and testimonials from our experienced team of editors and in-house lab testers to curate this list of eyelash growth serums. Independent studies into the effectiveness of eyelash growth serums are sparse, however anecdotal approval is widespread. Many users report visible improvement in the density of their lash line after around four weeks of daily (or nightly) use. Are lash serums safe? Biotin, also known as vitamin H, is usually sufficiently found in the foods we eat, such as egg yolk, cauliflower, nut butters, mushrooms, and bananas, but we occasionally need additional biotin if we are deficient. The daily recommended allowance for adults is 30–100mcg, and if your body doesn’t need the extra, it just passes through and is expelled through urination. Lash Serum FAQs Do homemade eyelash serums actually work? You only really need 2 natural ingredients —aloe vera and castor oil—to make your own lash conditioning serum. But vitamin E, coconut oil, and argan also make amazing lash moisturizers.

Castor oil sounds a bit scary, but don’t worry, people have been using it on their hair and skin since biblical times. The fatty acids and vitamin E in castor oil strengthen the lash root and stimulate growth. And while you’re getting longer lashes that fall out less, the aloe vera conditions lashes to reduce breakage. Eyelash serums, growth enhancers, lash perming, and lash extensions are extremely popular lately. While the desire for strong, long lashes never goes out of fashion (mascara, curling wands, and false eyelashes have been around for decades!), the tools and treatments used today are most definitely new. 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. Although our tester loved that this affordable eyelash serum enhanced the shine of her lashes, she didn’t notice an improvement in their quality or length.

Today, Rapidlash, Revitalash and UKLash use a low-dose form of prostaglandin analogues in their serums, supported with conditioning extracts, while the majority of newcomers opt for alternative conditioning ingredients such as peptides and red clover extract instead.
