Billie Eilish is currently on the European leg of her Hit Me Hard and Soft world tour, bringing with her a must-have Revlon product in her makeup arsenal.

The “Birds of a Feather” singer is not one to shy away from the faux-freckle trend. In fact, the ultra-cute look is a titular part of her tour makeup routine, as seen in a quick get-ready-with-me video posted to her TikTok at the start of her tour in December.

Eilish’s faux-freckle routine comes into play with help from Revlon’s ColorStay 5-in-1 Semi-Permanent Brow Ink, a product that, although made for brows, can do just about anything. The Eilish-approved brow ink is currently on sale for $9.97 at Amazon, meaning fans can recreate the singer’s freckle-faced tour look for cheap.

The hitmaker utilizes the brow product by simply dotting the product on her cheekbones and nose, blending the dots out with her fingers. Easy as pie. Revlon’s brow product comes in four shades, including Soft Brown, Warm Brown, Dark Brown and Blonde. Given Eilish’s complexion, it’s likely she opted for a darker shade to match her thick dark brows and equally dark hair.

The genius of this product lies in the thin, pointed brush applicator that allows for major precision, whether you’re building a brow or dotting on freckles. Eilish shared a peek at her post-show glam, sharing how her look — freckles included — stayed on after 1 hour and 35 minutes of sweating, dancing and belting.

That’s pretty impressive. This speaks to the intense staying power of the brow ink, given the formula is waterproof, transfer-proof and smudge-proof. Whether you’re adorning your face with freckles, or giving your brows the manicured salon look at home, this product won’t budge. Faux freckles have never been so easy.
