Thank you for posting the studies. After these studies were made public, the FDA unanimously voted to keep benzoyl peroxide over-the-counter. The following is a quote addressing this issue from "Acne & Rosacea, Third Edition", which is the most complete text on acne at medical libraries:
"There is some worry concerning the extensive, uncontrolled use of this very popular drug. It has been found that benzoyl peroxide is a tumor promoter in the two-stage model of chemical carcinogenesis in hairless mice...There has been much futile discussion among regulators about whether tumor promoton is a possiblity in man. The drug is prohibited in Japan, which is a disservice to acne patients. Extensive use for many decades is strong evidence that this drugs i neither a carinogen nor a co-cargcinogen."

But despite all of this information and evidently contadictory claims, if we use common sense, it appears that benzoyl peroxide is safe. It was introduced around 1930 and has been used by millions of people for decades with no problems. I myself am a personal study all my own. I have used lots of benzoyl peroxide for many years, and frankly, the skin where I use the benzoyl peroxide appears younger and healthier than where I don't.
Did I miss something? It's a disservice to acne patients that it is banned in Japan. It is neither a carcinogen or co-carcinogen. Dan goes on to explain how BP is very much a safe substance in that thread.
