Artistry Tips

Coat lashes from root to tip and build to your desired level.

Our custom, dual-sided brush was artfully engineered for all lash types and eye shapes. Use the flat side to deposit pigment and the hourglass side for fanned-out volume.

Formula stays soft and flexible throughout application so you can build natural to fanned-out volume and length. Easy to build and easy to remove.

Pro Tips

Application tips and tricks from Sarah Tanno, Haus Labs' Global Artistry Director and Lady Gaga's Makeup Artist.

"Since this innovative formula stays soft and flexible throughout the application process, you can build it to your desired volume level without it getting clumpy or flaky. Wiggle the flat side of the custom dual-sided brush at the base of your lashes to load pigment, then roll through the tips with the hourglass side. 1-2 layers will give easy, everyday volume—amp up your look with 3-4 layers for more dramatic, fluttery volume. Don't forget to use the tapered tip of the brush to reach those tiny lashes at the inner and outer corners of the eyes."

    The only mascara you’ll need!

    This is hands-down, the best mascara I’ve ever used. It gives you a beautiful length and I even noticed after two weeks of using it every day that my lashes have grown a little bit. I’m so in love with this!

    NEW FAVORITE MASCARA

    I have short thin Asian lashes and this volumizing and lengthening mascara does its job for me without it clumping. It holds the curl really well too which is a must for me because of my slick straight natural Asian lashes.

    Very Lightweight Formula!

    I’ve been loving the Haus Labs B. Structural Mascara! It gives my lashes the perfect lift and definition without any clumping or flaking. It’s very lightweight and feels like nothing on lashes plus it’s perfect for my sensitive eyes. It holds a curl all day and layers beautifully for extra volume.

    Amazing Volume & Length—No Smudging!

    I’ve tried countless mascaras, but HAUS LABS BY LADY GAGA B Structural Mascara stands out! The brush perfectly coats every lash, adding instant volume and length without clumping. It’s super black, lightweight, and buildable for extra drama.

    What do I love most? It stays put all day. The mascara does not smudge or flake, even on oily lids. Yet, it is removed easily with micellar water. Plus, it’s vegan and cruelty-free!
