A recent study demonstrated that there are three unique strains of Propionibacterium acnes; two strains are more prevalent in people with acne; however, one of which appears not to be pathogenic to humans and is more prevalent in people with 'clear' skin.

Which of the following statements about the targeted removal of 'bad' P. acnes and addition of 'good' P. acnes is INCORRECT?

B) Once removed, the invading pathogenic P. acnes cannot regrow on the skin.
