Benzoyl peroxide has been shown to be a tumor promoter and progression agent in a
number of animal studies. The clinical significance of this is unknown.
Benzoyl peroxide in acetone at doses of 5 and 10 mg administered twice per week induced
skin tumors in transgenic Tg.AC mice in a study using 20 weeks of topical treatment.
In a 52 week dermal photocarcinogenicity study in hairless mice, the median time to onset
of skin tumor formation was decreased and the number of tumors per mouse
increased following chronic concurrent topical administration of BenzaClin Topical Gel
with exposure to ultraviolet radiation (40 weeks of treatment followed by 12 weeks of
observation).

If it is used to turn benign papillomas (like a pimple) to malignant papillomas in lab animals at ONLY 5-10% applied ONLY 2 times a week from ONE source, How can the chem manufacturer state that it doesn’t?

If anyone can give me the name of a product or products for better skin, other than proactive, then I would grateful to hear about it.
Thanks =)
