Brows can make or break an entire beauty look. Unless you were blessed with elongated, perfectly sculpted arches that have just the right amount of thickness — think Audrey Hepburn or Brooke Shields — then it’s most likely you rely on an eyebrow pencil to brush hairs up into place and fill in gaps for a bolder finish.

One trusty formula that can always (and effortlessly) get the job done is the award-winning Brow Wiz from Anastasia Beverly Hills, which celebrates its 16th anniversary this year. CEO and “eyebrow queen” Anastasia Soare — and the mastermind behind Kim Kardashian’s stunning arches — tells Us how the iconic pencil is “unlike other brow products.”

Not only can the makeup essential “be used for subtle filling and detailed definition, making it ideal for any brow look you want to achieve,” but its “compact size” scores major points as well. “[It’s] easy to carry for on-the-go touch-ups, ensuring your brows look perfect at all times,” the pro notes.

It’s no surprise why A-listers love it, with famous fans ranging from Kendall Jenner and Chloe Bailey to Michelle Yeoh. “This is a really good brow pencil,” shared Jenner in a Vogue beauty video, who also referred to the bestseller as her “tried-and-true” brow product which she uses to slightly fill in the ends of both eyebrows so they’re the same length.
