Something you could try is a good foundation, if you really want to cover it with makeup. But if its not that severe and you just want to fix the redness a bit, try rinsing your face with very cold water for a few seconds in the sink or after a shower. It doesn't do much but it usually makes my skin look a little better.

Try not to pop your whiteheads but instead take a cotton swab q-tip and dab it with a couple drops of tea tree oil. Lightly dab each white head and the tea tree oil will help dry out the whitehead and shrink it.
