Everything supposedly causes cancer nowadays, but nobody has been able to prove it, they're only parroting each other with their all-natural blah blah. If you can show me just one reliable source, then please PM me. I'm pretty confident that -as long as you don't eat it- you'll be fine. If you're worried about some of your shaving gel/cream's ingredients, have a look at the EWG database: http://www.ewg.org/skindeep/browse/shaving+cream/ .

Also, I'm closing this topic, since it has nothing to do with acne.
