Gone are the days of over-plucking eyebrows to a mere pencil-thin line—instead, the new #browgoals are thick, borderline-bushy brows often seen on supermodels, celebrities, and all over your Instagram feed. With this beauty trend comes the desire for many to spruce up their brows into the fullest, boldest arches—and that’s where eyebrow growth serums come into the picture.

The latest non-prescription brow serums are designed to enhance the thickness of the brow hairs you do have and help stimulate growth in areas that are sparse. You don’t need to see a doctor to get a serum (as you do with the prescription lash-and-brow enhancer Latisse). Apply once or twice a day (following package directions), and some can show results in as little as two weeks.

What the pros say

There are dozens of over-the-counter brow serums, but they’re not all created equal, stresses Francesca Fusco, MD, a dermatologist in New York City. The best of these over-the-counter formulas pack peptides, adds Joshua Zeichner, MD, director of cosmetic and clinical research in dermatology at Mount Sinai Hospital in New York City. Peptides are “messengers designed to do a specific job—in this case, encourage hair growth and healthy hair follicle activity,” he says. Debra Jaliman, MD, a New York City-based dermatologist, agrees, noting that “peptides aid in creating a healthy foundation for the brows.”

And while many of the most effective serums include peptides, it’s important to note that they could cause irritation on those with sensitive skin. (Some other serums rely only on essential oils, which simply strengthen the hair you already have.)

Another key ingredient to look for is biotin, which is “known to improve hair health,” Dr. Jaliman tells Health. “It’s important for energy production to help promote the growth of additional hair follicles,” she adds. Dr. Jaliman also recommends choosing a formula that contains keratin, the protein that strengthens hair. And for even more effectiveness, look for serums that include fatty acids—like lipids, panthenol, or B vitamins—which can condition, thicken, and moisturize brows.

According to Dr. Jaliman, many growth serums that are marketed for eyelashes can be used on eyebrows, too, and are just as effective there.

As with any beauty product, some (often pricier) formulas will be more effective than others. But even if you don’t see the results you were hoping for, they can’t hurt—and at the very least, you’ll simply be conditioning your brow hairs. “If used correctly and as directed they are very safe for use around the eye area, and they do work,” says Dr. Jaliman.

What we say

Although brow regrowth doesn’t happen overnight, the picks below use dermatologist-recommended ingredients to add fullness and condition hair follicles to encourage growth. Plus, most of these options—including RapidBrow, VegaBrow, and RevitaBrow—were personally selected by our three derms, so you can trust that they’re the best of the best. No matter which serum you try, if you use it regularly, you should see a boost in the condition of your arches.

Here, the 8 best eyebrow growth serums for fuller, bolder brows, according to dermatologists:

Best conditioning: RevitaBrow Advanced Eyebrow Conditioner Serum


This tried-and-true brow serum packs peptides, the main ingredient both Dr. Jaliman and Dr. Zeichner recommend for growth benefits. The award-winning formula is also hypoallergenic and ophthalmologist-tested (so you won’t have to worry about eye irritation), and includes another dermatologist-recommended ingredient—biotin—to improve hair health and thicken sparse lashes with consistent use.

Best for serious growth: RapidBrow Eyebrow Enhancing Serum


If it’s serious brow rehab you’re after, Dr. Fusco recommends going with RapidBrow, a popular serum that’s chock-full of nourishing, strengthening elements. “RapidBrow has proven to be the go-to among my patients,” she says, adding that while the vast majority of people tolerate peptide-based serums well, this may not be the best option for anyone with super sensitive skin. Its fast-acting formula contains all of the star ingredients that our derms say are most effective in growth serums: peptides, panthenol, biotin, and keratin.

Best two-in-one: RapidLash Eyelash Enhancing Serum


If you love a good multi-tasking beauty product, this is the best choice for you. As Dr. Jaliman mentioned, just because a growth serum is marketed towards eyelashes, that doesn’t mean it can’t effectively work on brows, too. Case in point: This RapidLash serum, which comes from the brand behind the RapidBrow serum, above, comes personally recommended by Dr. Jaliman. She “really likes this serum” because it “contains ingredients that add fullness and can promote some new growth”—on both your brows and lashes.

Best vegan formula: GrandeBrow Serum

This vegan, ophthalmologist-tested formula uses a smart combination of l-proline (an amino acid) and hyaluronic acid to condition and replenish brows, while a natural blend of plant-based extracts work to strengthen the hair follicle and, in turn, promote regrowth. In a consumer study conducted by the brand, 100% of users reported fuller brows after 16 weeks of use, and one Sephora reviewer called it “a miracle product.” Another customer wrote, “It actually works…I’ve been contemplating a microblading procedure, then I heard about this serum. 2.5 months of vigorous and diligent using – my eyebrows are slowly getting thicker and thicker. Very satisfied with the results, I can’t believe they are growing back!”

Highest-rated: Pronexa LavishLash Eyelash and Brow Serum


This best-selling lash and brow enhancer features biotin—a star ingredient for hair regrowth benefits, according to Dr. Jaliman—to stimulate hair growth and thicken your arches. Effective on both eyelashes and eyebrows, the hypoallergenic formula should be applied once a day and promises noticeable results in as little as two months. Plus, LavishLash is a top-seller on Amazon and boasts a whopping 13,100 perfect five-star reviews from customers who say it really works. Some shoppers even compared it to the coveted Rodan & Fields’ growth serum and say it’s just as effective (if not more), but costs one-fifth of the price.

Best for thinning brows: BoostBrow Eyebrow Growth Serum


Just as the name suggests, this affordable option can give a serious boost to thinning or sparse brows. The potent yet gentle formula includes derm-recommended growth ingredients, like vitamin b5 and panthenol, along with natural fruit extracts—like grape stem cells—to nourish, protect, and strengthen hair follicles for fuller, bolder brows over time. Plus, 86% of customers gave the serum a positive review, with many noting how effective it is for filling in thin brows.

Best for Sensitive Skin: VegaBrow Volumizing Serum


For those with sensitive skin, we like VegaBrow; in addition to peptides, it contains anti-inflammatory botanical ingredients, such as red clover and mung bean, which are gentle on your skin while also being effective for hair re-growth. The safe, vegan formula can give you results in as little as 30 days with consistent, once-a-day use. Customers say they notice visible improvement in their brow health and call it “gentle but effective.” One shopper said “repairing 90s brows is possible” with VegaBrow, and another wrote, “I was the queen of overplucking – and was hoping to reverse the process. One month in and seeing some difference! Great product!”

Most affordable: Organys Lash & Brow Serum


While many eyelash and eyebrow regrowth serums cost a pretty penny, you don’t always have to shell out tons of money to see results—and this under-$25 option proves that. Despite the low price point, shoppers say it really works. Plus, the gentle formula contains dermatologist-recommended ingredients—including keratin and peptides—for optimal strengthening and thickening benefits, along with botanical-based oils like green tea and saw palmetto to replenish weak or thinning hair follicles. What’s more, many customers say they saw results from the serum way sooner than expected.
