Sometimes I’ll use the pointed end to apply setting powder under the eye area.
The way I use this most is by taking one of the larger flat sides and laying setting powder over larger areas of the face with it. The one I have is sort of flat with a lightly pointed tip and very soft synthetic bristles. This is available on Elf’s website but the photo looks a little different than the brush I have. Further down in the post I have comparisons for some of them if you’re looking for more information about size, shape, the way they feel, etc. I have many more but these are the ones I like to have close at hand after finding specific uses for each of them. Here’s a small group of brushes I use most of the time when I do my makeup.
