Brooke Shields says this serum boosts her iconic brows, you can get 2 for 1 at Ulta

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 GrandeBrow-MD, a popular lash-enhancing serum. If you want to try it, click "add to cart" now to get two for the price of one at Ulta.

Why is this a good deal? 💰

This brow-enhancing serum regularly goes for $38 for one tube, but if you take advantage of this buy one, get one deal, it's like getting it for half price Ulta right now. Not bad for fuller-looking brows, and it's a lot less work than trying to perfectly pencil them in each morning.

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 GrandeBrow-MD Brow Enhancing 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.

GrandeBrow-MD Brow Enhancing 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 GrandeBrow-MD Brow Enhancing Serum mega-fan—it has over 1,200 five-star fans, including our own reviewer.

Pros 👍

"As someone who went through high school in the 90s, when the skinny Drew Barrymore brows were all the rage, I, being a certified Drew fangirl, joined the crowd," wrote a convert. "My brows were plucked to within an inch (or millimeter) of their lives. I have been using this for about two months, and my once sparse, wispy brows are now gloriously thick and full, almost Eugene Levy-esque. I used to HAVE to use tinted brow gel all the time, but now I leave them be and they look great!"

"This brow serum changed my life," shared a rave reviewer. "This stuff is unreal. I was partially the victim of heavy-handed eyebrow waxers circa the 2000s, as well as just losing brow 'thickness' due to age. What I'm trying to say is my eyebrows have been nearly nonexistent for years and years. It's something I was super self-conscious about. This serum has grown my eyebrows back more than I ever could've imagined it would. My eyebrows are borderline bushy after using this serum for several months. I now can be a clear brow gel girly and call it good, instead of having to basically create them with makeup. It can be pricey, but absolutely worth it in my book."

"Forever my favorite brow gel that actually works," another fan wrote. "My 56-year-old brows look fabulous. They're darker, fuller & frame my mature face."

Cons 👎

While this product is miraculous, it isn't magic. Like most hair growth products, it doesn't give you fuller brows overnight. It takes a while to work, and then you need to stick with it (arguably, the exact reason you need this BOGO deal).

"I've been using the lash serum for years and love my lashes," wrote a reviewer. "The brow serum took longer to show results. After 6 months of nightly application, I am definitely seeing thicker eyebrows. One GrandBROW lasts longer than 4 months but I like to have a backup ready. Small effort produces good results."

Another shopper wrote: "[I] did see some improvement in some spots, but not as much as I would have liked."
