Lady Gaga’s 2025 is off to a hot start, with a number one duet (with Bruno Mars), a new single (“Abracadabra”) and a headline-making appearance at the recent ‘SNL50’ concert special, where she joined Andy Samberg and Lonely Island for a performance of “D-ck in a Box.”

But the multi-disciplinary icon is also making waves with her Haus Labs beauty line, thanks to the release of a new mascara. The B Structural Volumizing + Lengthening Mascara is the latest product from Haus Labs by Lady Gaga, and has quickly become a top purchase on sites like Sephora, with reviewers praising the product for its easy-to-use wand and powerful formula.

First released in January, Gaga’s mascara promises to help lengthen, nourish and hold your lashes for all-day wear. Haus Labs says that’s thanks to its new haircare-inspired B-Silk formula (a type of amino acid) that coats your lashes with bold color, flexible hold and buildable volume, while resisting smudging and fading for up to 12 hours. The addition of rice protein, meantime, helps to promote healthy, longer lashes.

Reviewers say the mascara goes on smooth and isn’t flaky or clumpy, with “nice lift and color” (as of now, the Haus Labs mascara is only available in a “Black Onyx” colorway). Shoppers also praise the product for its fullness in application — many say they saw a difference in just one coat. Haus Labs, meantime, says the mascara could increase your lash volume by as much as five-times their normal length. The company also says the B Structural Mascara is “ophthalmologist-tested, hypoallergenic, and safe for sensitive eyes and contact lens wearers.”

And while the formula goes on — and stays on — smoothly, reviewers say it’s easy to remove with a simple makeup wipe or cleanser. As Haus Labs posted on Instagram, shoppers agree that “the hype is real.”
