why would my skin have bumps if I'm not supposed to pick them?

Seems like they're meant to be picked. I know it looks bad after you pick it, but if you didn't that stuff might just sit in there forever! Eventually your body would have a continuous layer of gunk under the surface of your skin. Sometimes I wonder how a single pore or hair follicle can hold that much stuff. I don't think it will ever be possible to just leave it in there.
