I'm not the first—or the last—to say this, but let it be repeated: step away from the eyebrow tweezers. Luckily, my esthetician gave me this invaluable beauty advice when she first started waxing my eyebrows in middle school, but I know that's not the case for everyone. If you got a little over-eager plucking away your stray hairs, or if thinning out your brows to get that trending early-aughts style went sideways, don't panic. This is where eyebrow growth serums step in.
Sure, eyebrow pencils and brow tinting can temporarily make your brows look thicker and more voluminous, but to treat the root cause (and for a more permanent solution!), eyebrow growth serums are ready to come to your rescue and deliver full, bushy brows in a matter of weeks.
"Over time, our eyebrows experience a decrease in density, fullness, and growth of hairs due to aging or possible other external factors," says Licensed Advanced Registered Nurse Practitioner (ARNP) Maylen Cadenas. These include "skin conditions like eczema, hormonal changes, or diet deficiencies," she says. Utilizing an eyebrow growth serum can help mitigate or even reverse these natural effects of aging.
Not sure if a brow growth serum is right for you? "Anyone who wants thicker, fuller brows is a great candidate," says board-certified dermatologist Nazanin Saedi, MD. "Patchy brows, thin brows, and over-plucked brows will all benefit." If you're ready for thicker, healthier-looking brows, you're in the right place. Keep scrolling to shop for all the best eyebrow growth serums on the market, including expert-approved buys and beauty editor tried-and-true favorites.

With so many pricey brow serums on the market, seeing an under-$20 pick is refreshing, to say the least. And once TikTok found out about it, I've been seeing videos reviewing the serum non-stop. The attention is warranted. Thanks to a combination of peptides and other brow-boosting ingredients, the lightweight formula makes hair longer and stronger.
Key Ingredients: Peptides, panthenol, caffeine
What I Love: Well-priced; Lengthens and strengthens lashes and brows
What I Don't: Some reviewers wish it came with a spoolie for easier application on the lashes
Review for MC: "This instantly makes my brows look shinier and more conditioned, so though it takes weeks to start seeing any hair growth, I love the automatic effect upon application. It makes them look so healthy. The thin applicator wand is super easy to use, and I love that there's no weird scent to the product. Not to mention, the price is unbeatable." — Catharine Malzahn, Contributing Beauty Writer

If there's one thing Anastasia Beverly Hills knows, it's brows. Founder Anastasia Soare is fondly known by many as the Brow Queen, and the brand's brow makeup products have reached cult status several times over. So when the brand launched an eyebrow serum, the beauty world paid attention. A fellow beauty editor friend of mine swears by this serum, and once I tried it, I can see why.
Key Ingredients: Red clover extract, Korean red ginseng, panthenol
What I Love: Created by a brow expert; Editor-approved; Improves texture and manageability of brow hairs
What I Don't: Best for filling in a few sparse spots and boosting brow health, rather than for intense brow regrowth
Review for MC: "This doesn't flake in my brows, even under makeup, and I love how conditioning it feels on my hair. I'm also a sucker for cute packaging, and it comes in a gorgeous pink tube that feels and looks much more luxurious than other brow serums I've tried." — Catharine Malzahn, Contributing Beauty Writer

Review for MC: "I trust RevitaLash with everything—I've used their shampoo and conditioner to promote hair growth and the Revitalash Advanced Sensitive has nearly doubled my lash density. But perhaps my all-time favorite product of theirs is the eyebrow conditioner. It contains hydrating ingredients like green tea extract and biotin to strengthen and moisturize the area. Now I'll be honest: Results take time. But over the course of a few months, my brows have started to look so much fuller and thicker." — Samantha Holender, Senior Beauty Editor

Key Ingredients: Glycerin, arginine
What I Love: Conditions brows for maximum retention; Effective on both brows and lashes
What I Don't: Seems to be more effective on brows than lashes
Customer Review: "My eyebrows were getting sparse due to age, but I found this product when I was buying skin care. I use it every night and my eyebrows are so nice and full! My eyelashes look fuller as well, which is really nice. I don’t think this will make your eyelashes grow long, but it does help them grow in and it conditions and nourishes the hairs, which is important." — Amazon
Brow expert Joey Healy created this serum specifically for the over-pluckers and constant waxers of the world. As a celebrity eyebrow specialist, you can trust he knows what's up when it comes to all things brows. The paraben-free formula moisturizes, soothes, and supports the health of your brows, and, perhaps most importantly, it dries thoroughly enough to be worn under brow makeup (just make sure to wait five minutes after application to start your makeup routine).
Key Ingredients: Hyaluronic acid, hydrolyzed wheat protein, vitamins A, B5, C, and E
What I Love: Paraben-free; Can be worn under makeup; Promotes healthier brows overall

Castor oil is a natural ingredient that people have long sworn by to enhance hair growth, including Marie Claire editors. This innovative double-ended pen and spoolie makes it easier than ever to apply castor oil to your brows (and lashes, if you so choose!) without the mess. Coat your brows in the oil to improve softness, moisture, and, eventually, length and density. Users do warn, however, that less is more with this oil—like all castor oil-based products, it's thick, so if you use too much, you may risk it dripping into your eyes or coating your eyelids.
Key Ingredients: Castor oil
What I Love: USDA certified organic; Natural, single ingredient
What I Don't: Thick, so it requires practice and moderation for effective use
Customer Review: "I use this daily on my lashes and eyebrows. It has made my lashes longer and fuller and also made my brows fuller." — Amazon

Do Brow Growth Serums Really Work?
How does a daily swipe of gel work such wonders, you ask? The technology is very similar to that of eyelash serums. “Brow serums often contain peptides, biotin, keratin, oil, and other natural and active ingredients that work by supporting and strengthening the hair follicles within your brow line,” explains Dr. Saedi. “These ingredients also help condition and strengthen the brow hair that is present.”
Cadenas adds that if you're using a medication or serum that incorporates bimatoprost, it will "help to increase the length, thickness, and darkness of eyelashes and eyebrows. [Bimatoprost] works by increasing the amount of time hair follicles spend in the growth phase and by increasing the number of hairs that grow during this time."
Thanks to ingredients like vegan keratin and (most notably) peptides, eyebrow growth serums can "create proteins, which are the building blocks of hair," Healy says. Over time, this helps lead to thicker, fuller brows.
What Should I Look for in an Eyebrow Growth Serum?
Board-certified dermatologist Dr. Neera Nathan says that "It is really important to use safe, non-toxic products on the eyebrows or anywhere near the eyes. Certain ingredients, like mung bean or red clover, have shown promise to support eyebrow growth naturally."
How Long Do Brow Growth Serums Take to Work?
The length of time brow growth serums take to work depends on your current brow situation—results will vary if you're a constant plucker, frequent waxer, threader, or occasional brow shaper. "Generally, the more damaged the brow is, the more time it takes to see a maximum result," says Healy.
The most important thing is to be persistent. "As with any hair growth journey, you need to be committed and consistent," says Dr. Saedi. "If you stick with it, you should see fuller, thicker brows in three months."
How Often Should I Apply Brow Growth Serum?
For best results, make sure you're following a proper and consistent regimen. "Most eyebrow growth serums need to be applied twice a day for six weeks and once a day after that," says Healy. "It's important that it needs to be for six weeks because you want to saturate the hair as all of those hairs are entering their early growth phase."
A bonus? Healy says that most brow serums can also work as eyelash serums. Nothing beats a good two-in-one!
Are Brow Growth Serums Safe?
Like anything, eyebrow growth serums can have side effects in some people. "The most common side effects are eye redness, dryness, and irritation," says Cadenas. "These are usually mild and go away after a few days."
Dr. Nathan also reminds users to exercise caution with eyebrow growth serums in the same way you would with any other new skincare product. "Like anything, eyebrow growth serums can side effects in some people. Allergy or irritation can occur when using eyebrow growth serums," he says. "Before using any new product on the eyebrows or face, I recommend testing a small amount on the inside of the wrist first and waiting for two days to ensure there is no reaction before proceeding with regular use."
Still, since you're applying brow growth serums near your eyes, there are specific formulas to avoid, warns Healy. "The one thing you do want to avoid is hormones such as prostaglandins that can have bizarre effects in the eye area, including darkness underneath the eye and changes in the iris color." Dr. Nathan agrees, citing specific compounds called prostaglandin analogs, which include bitamoprost and latanaprost. "These ingredients can worsen the appearance of dark circles and also darken the natural color of the iris," he says, "which can be permanent in some cases."
Popular brow and lash growth ingredient Latisse, for instance, can potentially cause such side effects. "Latisse can cause more severe side effects in rare cases, including changes in iris color, vision problems, and allergic reactions," Cadenas tells us. "Talking to your doctor about potential side effects before using Latisse is important.”
Finally, it's important to remember that you're using a product designed to stimulate hair growth on any skin it touches. "Keep it away from your eyes and only apply it to your brow line," warns Dr. Saedi. "If not applied carefully across the brow line, you can end up with unwanted hair in other areas."
