I love sheer powders. I use them for touch-ups and setting, and I love how slim/compact this is. I keep it in my purse with a little travel brush to keep control of shine, and love it.
I've had a Jouer blush that fell out of the compact like I've seen in other reviews, but since I keep glue dots in my bathroom for when that happens with other products, I feel it's easily remedied. While not ideal, I still think this is a good setting/blotting powder to keep if you like minimal makeup and just use concealer rather than foundation, and you just need a little something to keep it in place.
