I've tried shadow bases, though not that particular one. What has helped the most is SuperMatte Anti-Shine, but it still does it some even with it. I've tried other similar products - which are what I meant by mattifiers - but they haven't worked as well.

Don't know why I didn't think to ask you directly, LOL! Let me know if anything else comes to mind . . . .
