I think sunblock would be an awesome, awesome addition to your skincare line ;D
I realize that some of the current moisturizers claim ingredients that provide sun protection, and that to be labeled as such would mean FDA approval/testing and whatever (I'm not an expert...I happened to be surfing another website which offered a sunblock, which wasn't labeled as one? i didn't quite understand that but...)
I was wondering if it would be possible to work out a sunblock?
