The directions say to apply the product onto the brush while it's turned off (important that it's off for this step so makeup doesn't fly everywhere!), then dot it on your face with the brush. In this video, you'll see that I start with spots of foundation all over my face. Then you turn the brush on and start blending the makeup into your face. I was scared it would splatter, but it didn't one bit.
The directions tell you not to move your wrist in a circular or sweeping motion because the brush will do the work for you. I have to admit, I couldn't help myself, as you can see, but I was still utterly shocked by how well the device blended my foundation. Not only did it do a better job than I ever could, but it also cut the application time in half. It was fast and easy.
