Dr. Will Kirby (aka "the evil doctor" who won Big Brother 2) visited The Doctors today to talk about — and extract — open comedos... otherwise known as blackheads.

According to Dr. Will, blackheads are clogged hair follicles, while pimples are infected hair follicles, and neither should be extracted or popped using fingers (which all the experts say, but how can you resist?). Dr. Will used a little metal tool on one audience member to extract a blackhead from her back. After seeing that, I ordered one online. It comes with a lance!
