For those who've used glossier boy brow- how does this compare?

They� re pretty similar. I think the Kosas has a little more viscosity and I preferred the pigment of Glossier� s medium brown because it was slightly more cool toned. But the Glossier would fade throughout the day and Kosas doesn� t. I stick with Kosas because it� s a great value it lasts 3-4x as long as boy brow.
