Can't live without it.
In my experience this stuff will stay on happily for 24 hours. I've slept in it. I've swum in it. I've sweated in it. It just doesn't budge. It's also natural-looking and easy to apply with brush-strokes that mimic the look of naturally full, soft brows. I use 25 Ash, a colour only Adore Beauty carries in Australia, and it's a medium cool brown with no brassiness. On days when my skin is paler, or I want a more subtle brow, I can mix it on my wrist with a bit of long-wearing foundation or concealer and it still stays put.
I recently ran out of this and used some other brow products in my arsenal for a couple of weeks before I got around to buying more. When I finally did, I immediately noticed the difference. It's far superior to everything else I've tried. This product does everything I want it to do and more.
