Paul Holaren asked the Naked Scientists:
Question for Chris regarding acne treatment:
Could "planting" a good bacteria on your face after an antibiotic treatment prevent future breakouts?
My assumption is that the body's immune system is reacting to a particular type of "bad" bacteria that grows on the face. Otherwise acne would be present on other body parts too (e.g. hands). Also, I'm assuming antibiotics would clear or lower the population of the bad bacteria creating a void that "good" bacteria could fill. A home remedy may be as simple as spreading yogurt on your face.
What do you think?
