Viruses to Kill Acne Bacteria:

Scientists at UCLA have figured out that a harmless virus that lives on our skin could be the next big gun against acne. Think of them as tiny little Terminators on your skin that are programmed to kill P. acnes bacteria. The virus, called a phage, essentially eats up bacteria like a Pacman. Unfortunately scientists still need to figure out how to harness a protein from the phages to turn it into an active treatment, so this one is likely years away, too.
