Quick way to get rid of acne by next saturday?

I'm going to a concert saturday, and I can feel this big pimple coming up. I really want to pop it, but so far I'm resisting, haha. I've been using the oxy maximum acne-fighting pads for a while, but they don't seem to be helping that much. Most of the creams I tried just dry out my skin and don't really help on a long-term basis. Ideas?
