The 13 Eyebrow Growth Serums That Really Work (2025)

"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links."

Today's eyebrow trends can be divisive. Barely-there, skinny brows appear to be making a comeback (welcome back, the ‘90s), while cases of eyebrow blindness–swinging to the other side of the pendulum–have flooded TikTok to spotlight the era of thick brow pomade and unplucked brows. But getting thicker, fuller brows will always be on trend, and that’s where the best eyebrow growth serums come into play.

While feather-light pencils and strong-hold gels can fake a full brow, a growth serum is the most effective way to get to the root of the problem. Similar to your skincare products, these formulas include key ingredients, like peptides, antioxidants, and amino acids, that keep hair follicles well-nourished while supporting healthy growth for months. "The ingredients used for eyebrows are similar to those used for eyelashes," board-certified dermatologist Elizabeth Bahar Houshmand tells Bazaar. "Some ingredients I recommend are peptides, which can lead to enhanced thickness and length; amino acids to help with hair breakage; hyaluronic acid, vitamins A, B5, C, and E to protect and condition the hairs; and botanical ingredients like white tea, licorice, and rose to support the health of your brows."

And just like any other treatment serum, such as lash serums or retinol, the key to growing out your brows is consistency. Experts recommend applying an eyebrow growth serum once–even twice–daily for noticeable, long-lasting results. We’ve tapped top dermatologists and sourced hundreds of customer reviews to find the best eyebrow growth serums that work, from The Ordinary to Augustinus Bader.

RevitaBrow Advanced Eyebrow Conditioner Serum

Multiple derms mentioned RevitaBrow as their top pick. "It has peptides, biotin, lipids, and panthenol which in combination can condition and strengthen brow hair while preventing brittleness and leading to shine and fullness," board-certified dermatologist Matthew Elias says.

One satisfied customer writes: "This product really works! Now that I'm in my sixties, my brows have become significantly lighter and thinner. I bought this product based upon its reviews, but I wasn't expecting much. Within three weeks, I noticed that my brows were filling in, and after about three months, my brows had completely filled in. I still have to use brow pencil, but only because some of my brow hairs are grey. I don't mind, though, because at least now my brow pencil has actual brow hair to cling to. I plan to continue using this product." —Rhonda D.

What are some red flags that an eyebrow serum is irritating your skin?

If you experience any itching, swelling, or redness in the area, discontinue the use and get in touch with your doctor. "These are signs you could be allergic to the ingredients," Houshmand warns. And just so you know, over using your tweezers aren't exclusively to blame for hair loss in that area. Thinning can be caused by a variety of hard-to-control factors, including diet, stress, and hormones.

Can traditional hair growth formulas also work for brow growth?

"Minoxidil or Rogaine can help with brow growth," board-certified dermatologist Sarika Snell says. "It promotes the anagen growth phase of the hair follicle. I tell patients to use it once per day and wash their hands with soap and water after applying it, so they don't grow hair anywhere else on their face." For even more brow-growing power, you can ask your doctor for a prescription to Latisse, the gold standard of hair regrowth treatments.
