Think of a pimple as a little sack that holds oil, debris, and acne bacteria, says dermatologist Zakiya Rice, MD, an assistant professor at Emory University School of Medicine in Atlanta. What we call the pustule is actually keeping the bacteria nice and contained, she says. When you puncture the pimple's outer skin, the gunk oozes out. If the bacteria in that gunk splatters and lands inside other pores, it can lead to more pimples. There's another risk. Poke, pick, prick, and prod a pimple, and you can force the debris and bacteria even deeper into your skin.
