I use this brush to apply setting powder over under eye concealer. It's the perfect size for sweeping/blending powder lightly in back and forth strokes under the eyes. It's nice and soft too, so i never get a scratchy feeling. I started applying powder under my eyes in this way once I saw Risa Does Makeup on YouTube describe it as a better application method for women over 40. And, my it does work - no cakiness that I used to get even with a damp sponge. Of course you have to tap the brush to remove excess powder before application, but if you're over 40, give this brush and method a try.
