Drawing Paste | Kiehl's
Totally weird name, and even odder consistency (thick, sticky and blue), BUT it's amazing. I dab it on as soon as I feel a zit coming on and they disappear. I also put it on my t-zone to reduce oiliness and improve the texture of my skin. Only drawback is that it's bright blue and it stays wet/sticky when it's on your skin - so your best bet is to use it when you know you're going to be home for a few hours (because it's best left on for a few hours, or even overnight).
