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."

    Amazing

    It gives my lashes the perfect volume, feels super lightweight, and doesn’t make them stick together.

    Lo recomiendo

    Me gustó por qué no deja grumos, las pestañas las deja separadas y quedan rizadas, muy fácil a la hora de despintarme
