If a chemical is used to induce skin cancer in lab animals, should humans use it two or three times a day in 3 or four different products? Should the companyies selling products containing chemicals that are used to induce skin cancer in lab animals have to state this on the label?

If benzoyl peroxide breaks down upon contact with skin, why use it? Why not just use the 'safe' by-product combination?

"Benzoyl peroxide breaks down in contact with skin, producing benzoic acid and oxygen, neither of which are significantly toxic.
When applied to skin benzoyl peroxide has been shown to induce cancer, but only when used at 100% concentrations; it has not been shown to do this at the far lower concentrations used for treating acne, and at lower concentrations benzoyl peroxide has not been found to be mutagenic or carcinogenic."
