Before you run for the hills at the sight of blue (yep, blue) mascara, let me explain! If there's one craze I couldn't quite understand this past year it was coloured mascara. That and twerking, but that's a story for another day. That's until I got my hands on this CK One Colour Mascara in Electrify. The shade itself is outstanding, but it's the brush that makes me weak in the knees. You can twist the top of the tube, which allows you to customize the shape of the brush. Still with me? For example, twist left to compress the brush for volume. Or if you're feeling spontaneous, twist right to extend for a little more length. Is that not the most innovative and life-changing thing you've ever heard? Ok, maybe not, but pretty damn close. Would you dare to step outside with blue lashes?
