What do you use for touch-ups?

Maybe it's because I have to do sun care specifically in the summer, but I find it stifling if I apply too much base makeup or make it too thick. So, I usually just use a cushion foundation as a base and carry a sun cushion for touch-ups when I go out. I'm curious if you users also only use a sun cushion for touch-ups during the summer, or if you just stick with the cushion foundation you use at home.
