How to get a flawless finish that stays put through hot days?

"The trick is to apply foundation only over key areas," says L.A. makeup artist Michele Burke. The steps:

First, dab a sheer skin-tone-matching foundation — they're the easiest to blend. Try Max Factor Seamless Make-up.

Then finger-blend the makeup outward — most of the coverage will remain in the center of your face where redness usually occurs and then fade toward the hairline where you sweat the most.
