I liked for a long time looking for this powder. I do not know how it behaves when applied with a sponge, I do not use it. Nanoshu brush or over BB-cream, or independently. Covered with a thin, matting medium, enough for me. Under my fair skin is well adjusted, of course, if you do not overdo it. In my opinion - a good product, if used properly. Who love powder oneself during the day a hundred times and make your face puff pie - matting napkins to help you, and shine will be removed, and dust from the face will not go away, no matter how thinly it may be applied. And about the fact that the powder changes color .. any means, though tonalnik though powder applied to "naked" skin without the base reacts with the sebum and oxidized. As a result, the face turns yellow or dark. With this powder the same thing - use a good primer, and everything will be fine)
