Removing a powder

Hello there! I am using Kryolan's grease paints for the face. To make it matt & resisant I am using a powder (applied with big brush). And my question is: how do I remove powder's artifacts from face? White powder on black paint looks terrible and kills the immersion. Cotton pads only damage my paint, brush itself is not effective.

Please move this thread to "How'd you do that?". Thanks.

Have you tried using a black power like Starblends?

You could try applying with a lolipop/smoothie blender:
