This is a Dermatology related question: Had a deep pimple, what I call "underground", it looks like I got mauled by a prehistoric mosquito. At times they just never surface and then leave a dark mark on my face for weeks! And if I do force to the surface, well then its that much worse. How do I go about getting rid of this scaring? Normally if I get a pimple I'll slap something to pull the moisture out, but the "undergrounds" are the killer for me. Since they are more larger and annoying, never surfacing.
