I have heard that you can use a non whitening toothpaste overnight to get rid of a pimple. I have also heard that eating cucumbers will help. (i havent tried those i just heard of them). I recommend that you try not to touch your face much, wash your face at least twice daily, and drink lots of water.
Some face washes i recommend: Clean and Clear morning burst , Neutragena oil free acne wash, Oxy, or Oxy face pads
