I didn't like this brush for concealing under eyes, I thought it was very difficult to work with and took a very long time. BUT I did like this brush for contouring! It's perfect for precision carving out cheek bones and slimming your nose.
This is a very nice setting powder. Not exactly translucent as it does have color to it but it isn't heavy. The powder itself is very light and perfect for baking under eyes to lock in that concealer just as it says. I also use it to set the rest of my face and it really keeps me looking matte all day.
This brush is not a setting powder brush. It was great for setting my entire face except under my eyes which needed it the lost. The brush itself is really nice and the packaging is perfect. I use it for blush and think that should be its intended purpose.
