Thankfully I only get a couple of pimples on my face at any given time, so they're fairly easy to deal with...but of course they always have to show up right before a con! I generally use concealer on the zit itself and blend it with a layer of powder overall (Clinique is my brand of choice, but I don't think it really matters.) If my skin gets particularly oily, I use a blue Neutrogena astringent, but I forget what it's actually called.
