The 12 Eyebrow Growth Serums That Really Work

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

While a highly pigmented brow powder or pencil temporarily does the trick to fill in sparse areas, true beauty enthusiasts know that using one of the best eyebrow growth serums is the most effective way to get to the root of the problem.

These formulas contain key ingredients, like peptides, antioxidants, and amino acids, that keep hair follicles well-nourished while supporting healthy growth for months to come. "The ingredients that are used for eyebrows are similar to those used for eyelashes," board-certified dermatologist Elizabeth Bahar Houshmand tells Bazaar. "Some ingredients I recommend are peptides to promote healthier lashes, 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 many of the best lash serums, brow treatments should be consistently applied—sometimes twice a day—to get noticeable, long-lasting results. Here, we’ve tapped top dermatologists and sourced hundreds of customer reviews to find the best eyebrow growth serums that actually work, from The Ordinary to Augustinus Bader—shop their top picks below.

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.
