The secret to clear skin may lie in the cocktail of strains of a common bacterium that lives on your skin. Propionibacterium acnes bacteria are abundant in the pores on everyone's face. They have been implicated as a cause of pimples, but why they aggravate spottiness in some people but not others has been a mystery. The discovery that there are "good" and "bad" types of P. acnes offers a clue. It also opens up the possibility of developing treatments customised to the flora of an individual's skin.
