My understanding is that products you use topically really don’t penetrate skin well. Our skin is designed to keep things out and does a good job of this for the most part (rare exceptions being patches that only work for certain drugs and are engineered to allow the drug to penetrate). There’s some evidence that really more than half of the natural and synthetic substances we’re exposed to (even in healthy fruits and veggies) can “cause cancer” in laboratory rodents. The good news is that the rodents are given massive, massive doses of the substances that don’t correspond to the kind of exposure we humans get. So, many people think rodent studies really don’t map on well to real-world risks and you’re best off looking for studies of real-world usage by humans (my read: the above reviewed human studies in the blog post did not find anything concerning w/ bp).

It states use over one year BP causes cancer…?? Was wondering if you had seen this… I have been on Proactive for over a year and it has worked better then some perscriptions.

AND have you ever heard of Silicol Dioxide with success in acne?

Thank you! It is wonderful to have this site.
