For work? Lipstick and lip balm. I actually work at a pizza place. I'm on the move constantly when I'm not taking the phone orders, so I get thirsty & drinking all the time wipes off my lip product, so I always take something to glam up my lips.
Right now I'm alternating between MAC slimshine in Ultra Elegant and Neutrogena Moistureshine Lipsheer in Cool Nectar. For lip balm I take Burt's Bees. When I run out of my drugstore lippies, I'll switch to toting my more high end lipsticks to work.
I'm only there for 5 hours max per day, so my eye/face products never run off because I use a primer, so I never need to touch up my eyes at work.
