Bump.....I'd like to know that also. I live in Florida and have always been a sun worshipper.

Also, for you people who are thinking of using retin-a or renova.....it causes hair growth on your face. You don't hear this too often because they don't want you to know that part, but do some research and you'll find this to be true. I used it for a year and a half and now have a major overgrowth of facial hair to deal with and believe me, I'm not the only one out there. Be careful!
