12 Best Eyebrow Growth Serums That Testers Say Actually Work

This star OTC pick includes a prostaglandin analog (like what you’d find in Latisse), as well as saw palmetto and a biopeptin complex—two ingredients that help strengthen and condition hair follicles, says Dr. Wolinsky. It’s another great pick for sensitive skin, too, since the brow gel is hypoallergenic and nonirritating, as well as vegan and cruelty-free.

• Pros: Expensive; strengthens and conditions
• Cons: Some reviewers experienced tinting skin
• What our tester says: The wand makes this serum super easy to apply, and it worked pretty quickly. I began to see results after about four weeks of daily use, but felt like six weeks was the sweet spot. It definitely filled in spots where my brows were having a hard time growing on their own. —Jordin Bjelland, a makeup artist from Montana

Proteins, peptides, and vitamins? Check, check, and check. This brow-boosting serum includes all of the ingredients dermatologists say you need for fuller, healthier-looking brows. And the brand claims you’ll get them in just 30 days. Reviewers support these claims, with many noting they saw results in as little as two weeks.

• Pros: Works quickly; vegan
• Cons: Expensive

What our tester says: I have sparse brows, but after just a few weeks of using this product, they were noticeably fuller, and looked as if I'd used an eyebrow pencil. You do have to keep it with it (once I ran out and stopped using it, brow life went back to normal), but it totally works and it couldn’t be easier to apply—simply swipe all over the area, no precision needed. —Brie Schwartz, Glamour commerce director

It may not contain any prostaglandin, but this formula does have an ingredient called myristoyl pentapeptide-17 that’s credited with stimulating keratin genes, says Dr. Wolinsky. It’s a great pick for anyone with sensitive skin—it’s cruelty-free and vegan, plus made in small batches with naturally derived ingredients in the US.

• Pros: Suitable for sensitive skin; cruelty-free and vegan
• Cons: Expensive; short brush
• What reviewers say: I’ve always had very blonde, thin brows and had major brow envy. I tried micro blading and I didn’t love it. I thought I would be wedded to dip-brow and penciling for the rest of my life. But no! Now I can enjoy my natural brows because of Nulastin. I even have enough brow hairs now that I got them laminated the other weekend, and they look awesome. —Amazon reviewer

If you’re concerned about any potential side effects from prostaglandins and prostaglandin analogs, including redness or hyperpigmentation, look for formulas with a combination of peptides, keratin, and vitamin B5 instead—all of these ingredients support gentle, healthy hair growth.

• Pros: Gentle formula; brush is easy to use
• Cons: May take up to 12 weeks to see results
• What reviewers say: I’ve been using this product consistently for approximately two and a half months. My eyebrows grew in length so much, I had to trim them every three to four weeks! —Sephora reviewer

Take this powerful product as proof that you don’t have to spend a pretty penny on a great eyebrow growth serum. This one is more affordable than most, but it has a trio of proteins to strengthen follicles, peptides to encourage new growth, and conditioners to nourish hair.

• Pros: Works quickly; relatively inexpensive
• Cons: Doesn’t last long
• What reviewers say: I have tried all of the eyebrow serums out there, but this one is the best! I suffer from the ’90s thin-eyebrow trend, and I have tried everything to make them grow back. This serum is so easy to apply and it works! It’s not sticky or lumpy like some others, and I saw results in a week!! —Ulta reviewer

Get more bang for your buck with this two-in-one serum that targets both lashes and brows. It’s packed with plant peptides proven to increase lash length and improve brow density, says Jaimie DeRosa, MD, a double-board-certified facial plastic surgeon and founder of the DeRosa Center in Boston and Palm Beach. It also features a more unique antioxidant—hemp-derived cannabis seed extract—to hydrate and condition at the same time.

• Pros: Works quickly; fragrance-free
• Cons: Some users say it irritated their skin
• What reviewers say: This product has brought back brow hair that I haven’t been able to regrow in 10+ years. The outer corners of my brows were sparse due to years of waxing, overplucking, and thyroid issues, but this product really impressed me like none other has. It has filled in my brows so much that I no longer have to draw in the ends of my brows. —Sephora reviewer

Natural beauty fans can reap brow-boosting benefits of serums too. It may be formulated with only clean, vegan ingredients, but reviewers say it really works. Derms like that it’s packed with nourishing and stimulating ingredients like active phytomolecules, biotin, and zinc.

• Pros: Natural and vegan formula; dries clear
• Cons: Expensive
• What reviewers say: After a few weeks my eyebrows are visibly thicker. I bought this because the ’00s had us shaping our eyebrows pencil-thin, and I really want the thicker contemporary look. This is really helpful, and my aesthetician noticed the growth also! —Sephora reviewer

It may be exceptionally pricey, but this product has a special claim to fame. It’s formulated with the brand’s patented TFC8 technology, which helps skin cells absorb and use the serum’s key hair-growth-boosting nutrients: arginine, taurine, castor oil, and hyaluronic acid. Make it go the extra mile by applying the serum to your lashes too.

• Pros: Brush is easy to use; gentle formula
• Cons: Very expensive
• What reviewers say: This serum is great! The brush too! Easy to apply with brows and lashes with the same applicator!  The formula was gentle enough for me. And I have visibly darker brows and lashes, and growth to both. —Sephora reviewer

It’s one of the most inexpensive eyebrow growth serums on the market, but it’s just as hardworking as those five times (or more!) the price. Not to mention, it’s a highly versatile product—you can use it on both your brows and your lashes. More than 19,000 Amazon reviewers give the serum five stars, saying the blend of peptides and botanical extracts delivers fuller, shinier brows in just two months of consistent use.

• Pros: Inexpensive; versatile
• Cons: Some reviewers say the applicator is a bit too small
• What reviewers say: I’ve bought this twice now (using for both my eyelashes and brows) and I’m truly amazed! I started out doing it 2x a day (AM/PM) and saw noticeable growth by the end of that week. —Amazon reviewer

Dermatologists tell us Latisse is the only FDA-approved proven topical to thicken eyebrows and lashes. Latisse really works, which makes it a common choice for anyone who experienced hair loss due to hormonal changes or chemotherapy, says Ashley Brissette, MD, a board-certified ophthalmologist at Weill Cornell Medicine and founder of the eye care brand Daily Practice. The downside? It can create side effects like burning, itching, and light sensitivity. Of course, you do also have to see a health care provider for a prescription. Thankfully, you can do so virtually on a platform like Ro.

• Pros: Only proven formula; works quickly
• Cons: Requires a prescription; has some side effects
• What our tester says: I used Latisse on my lashes and then I used the leftovers on my brows. I did it for about six months, and it definitely helped fill in the gaps from over-tweezing when I was young. —Yun Yu Quinn, a PR professional in New York City
