You have a natural gut flora; you have a natural skin flora. Screwing around with your gut flora is uncontroversially seen as a bad thing. Screwing around with your skin flora strikes me as a similar argument.

I would be interested to know of any summary of dermatology studies on anti-bacterial soaps. I would theorize that much as screwing around with your gut flora leads to all manner of uncomfortable stinkiness, so should screwing around with your skin flora. So people who use overly aggressive decontamination solutions on their bodies should be stinkier and have more and weirder rashes than people using normal stuff.
