Get some hydrogen peroxide (very cheap) and soak some on a cotton ball and hold it to the area for 5 minutes. It will sting at first quite a bit and be fairly red, but by morning it should be totally dried up or at least minimized significantly. Leave it on overnight. I did this to a few pimples I had and I noticed right after applying it, that it was smoothed over. I used 70% which is not recommended by most people, but it's the perfect strength for me.
