I’ve tried using a sebum control powder that’s in loose powder form. The usual problem is that it can get kind of messy when opening the case from inside your bag, and the powder spills over your bag and your stuff if you are not careful. Even if you open it away from your bag, the tendency is you will make a mess on the sink or on the floor when using it. This one being a compact powder, prevents this from happening, so this is something that’s better on the go. The loose powder, you can probably just leave at home before you leave, and this more for touch-ups inside your bag. So that you can look fresh when getting a bit or very oily when outside especially during a humid weather.
