Legendary make-up artist Pat McGrath is used to having celebrities in her chair, so she tested this 'FetishEyes™' mascara on Kaia Gerber and Hailey Bieber before releasing it to the public. Delivering intense black pigment, the formula coats lashes so they're left looking fuller and noticeably longer - swipe through once for an ethereal look or build up the layers for something more dramatic. It's also blended with strengthening Peptides and nourishing Panthenol.
