water has been shown to give mice cancer, in large amounts! lol seriously though, there is something to be said of quality of life!

And its good for everyone to use sunscreen daily, and to get any weird moles or spots checked out by a doctor asap. As for the healing aspect, I find my acne heals much better when I use BP. As for free radicals,
