I Googled and found that Kevin Trudeau uses questionable advertising practices.

However, what matters is the message -- your skin more quickly absorbs chemicals than if you swallow the chemical. Try the saltine experiment. When you pull the cracker out of the mineral oil, it's a crispy as it was when you put it in. It's a clear illustration of what mineral oil can do to your skin because the mineral oil (i.e., petroleum) creates a sort of hermetic sheild over your skin. Remember when the Goldfinger movie came out and learning that if anyone ever actually painted themselves with gold, they'd suffocate to death because their skin couldn't breathe.
