Brooke Shields says this serum boosts her iconic brows — grab it on rare sale for 20% off (2025)

Quick question: When you think of bold, beautiful brows, who's the first celeb who comes to mind? If you said Brooke Shields, we're right there with you. Since she was a child model, her striking eyebrows have always been a signature part of her look. How does the 59-year-old icon continue to stun decades later? Part of it, she says, is thanks to Grande Cosmetics Brow Enhancing Serum, a popular lash-enhancer. If you want to try it, click "add to cart" now while it's 20% off.

Why is this a good deal? 💰

This brow-enhancing serum regularly goes for $73, but right now it's on offer for $58. Not bad for fuller-looking brows, and it's hundreds of dollars less (and zero pain!) compared to microblading. Plus it's also a lot less work than trying to perfectly pencil them in each morning. (And noticing on the way to work that you didn't quite get them ... even.)

Why do I need this? 🤔

In 2021, Shields posted an Instagram reel to share how she creates "the eyebrows," highlighting a couple of her favorite brow products. Though she didn't use eyebrow serum in the video, she did call out the product in the comments. One commenter wrote, "How did you keep your eyebrows after your pregnancies? After my daughter, mine are so sparse and used to be amazing." Shields responded: "[I] highly recommend this product from Grande Cosmetics," alongside a link to the serum.

The serum is made with a combination of vitamins, peptides and amino acids in a botanical extract blend specially made to help fill in brows, add volume and boost strength. The brand touts fuller, thicker-looking brows in six to eight weeks, with full improvement after four months of consistent application. According to many users, including Shields, it works just as well promoting growth and thickness for eyebrows too. Either way, the serum is ophthalmologist-tested, so you can feel good about giving it a try.

Application is easy: For lashes, apply once daily on a clean, dry brow focusing on overplucked or sparse areas, using a single dip into the tube for both eyes. Allow two to three minutes to dry, and that's it! (Try not to get it into your eyes, but if you do, just rinse with cool water.) For the best results, the brand says to every day for four months, then you can switch to applying every other day for maintenance. If you want to try the lash serum (which is also part of the buy one, get one deal) apply once daily on a clean, dry upper lash line, like you would a liquid eyeliner, using a single dip into the tube for both eyes.

What reviewers say 💬

The Blue Lagoon star isn't the only Grande Cosmetics Brow Enhancing Serum mega-fan—it has over 4,700 five-star devotees, including our own reviewer.

Pros 👍

"It works!" raved this beauty. "I’m four months in and seeing results! After plucking my brows in the '90s and 2000s, I had given up all hope. The key to success is to apply every night. I wash my face and brows, apply eye cream on my lids and brows and then apply serum. The key is moisture IMO! If you use before makeup, let it dry five minutes and then apply your brow pencil. Another key is to not pluck at all! Do not trim your brows. Just comb them up and let them grow. I’m in the awkward growing phase but it honestly looks better than over-plucked brows."

"Oh my gosh, this liquid works great," shared another fan. "My eyebrows grew back, and I have fantastic eyebrows again! Yay! I used to draw in my eyebrows every morning with a pencil, and enhance what I had with a mascara brush, and I don't need that anymore because my eyebrows are perfect again."

This convert revealed: "I had zero expectations but decided ‘why not give it a try?' My eyebrows have already sprouted a few fine eyebrow hairs. Very exciting! Will continue to use/purchase. Not every product works the same for everyone. I got lucky this time!"

Cons 👎

"I don't have the money for microblading and refuse to get tattoo brows," said this reviewer. "You have to apply this daily and consistently ... The first [tube] only lasted a month or so, and that's my only complaint since it's pricey."

This shopper agreed: "My only complaint about this product is it’s very expensive. But at least it works!"
