I use this with translucent powder to lightly set in my foundation as a finishing touch. It is so soft and full! I know that some people like to "buff" in the powders and foundations that they wear which can be a bit aggressive for this type of brush based on the lengths of the hairs. With this, I like to sweep the powder across my face which has been really convenient and quick.
This brush does a good job, but the hairs fall out all over my face when I use it. It takes me a full two minutes to pick off all the small black hairs on my face, which is time I'd rather not spend in the morning. I returned the brush and bought a new one to see if it was just a fluke, but alas, I had the same problem.
If this is a problem for you too, I recommend switching to a blush brush that is not made of natural animal hair. Synthetic brushes do not shed, nor do they smell like wet animal when you wash them.
i am using this brush with my oil-controll powder and i see it works better then the sponge it comes with and it. it gets better coverage with this brush and they last long when you take care of them but this one is really cool i like the way it feels
