Nope -- I just carry blotting sheets! As long as I use blotting sheets at least once a day (2 or 3 times is better, if I remember), it helps soak up the oil, and my makeup looks fine afterwards! In fact, the only makeup I carry with me is a lipstick or gloss!
However, if I'm going out after work, I will touch up my mmu after work before I leave. So I suppose if I was out of the house *all* day and wouldn't have a time to touch up after work, I might consider carrying my foundation and concealor with me to touch up later in the day.
