This brush is a hidden little deal at Sephora. I got mine for my undereye concealer and it's perfect. I just gently sweep a lil concealer on with it and pat to blend. It's like $8 too, crazy good deal. Doesn't shed and is gentle on my skin.
For the longest time I searched high and low for a brush that I could use to apply my paint pots. My concealer brushes were either too large and awkward or too thick. Applying with my finger could be sloppy and weird. So when I saw this brush at Sephora I picked it up to give it a try. I absolutely adore this to apply my cream shadows. It is the best thing I could have asked. It applies cream shadows evenly and smoothly. The price is pretty cheap too, compared to other concealer brushes. I haven't used this brush for concealer at all because I use my finger. But I'd assume its great because its so fantastic for my cream shadows :)
