Since launching the incredibly popular Boy Brow, we've been patiently waiting for Glossier to expand their brow offerings. And starting June 12th, the wait is finally over. Introducing Glossier Brow Flick (£15), a water-resistant, "microfine detailing pen" that comes in three shades — Blond, Brown, and Black (just like Boy Brow). The superfine brush tip is similar to that of a liquid eyeliner, while the formula is incredibly sheer, giving you the ability to to draw on thin, hair-like strokes. Use it to fill in sparse patches , add definition and shape, or achieve a micro-bladed effect. Then, when you're done, you can set it with Boy Brow to get a truly perfect set of arches.
