Count me in as another who wears make-up as well. I wear Bare Minerals foundation, a swipe of mascara and some chapstick to keep my lips from getting sunburn.
At home, I wear eyeshadow and blush, but skip those for the parks. With all of the running around and sun, if you aren't naturally flushed within the first 15 minutes of being there---you might want to check your pulse!!
