Carry oil blotting papers as well. It really helps if you start with a clean dry face, apply an oil free primer-one with dimethicone-a foundation that is your exact color,blot with an oil sheet, retouch, then add powder. Buff the powder in! Use blotting sheets during the day. Oil is the enemy-that is what oxidizes! (makeup has preservatives) Even mineral makeup needs to be touched up with blotting papers throughout the day.
