Maybe that's not a good sample? Both by size, and selection, insofar as if you've recently got disfiguring scars perhaps you'd be less likely to make and share a video of yourself. Also, how long does it take to know if marks from pox sores are going to be permanent scars anyway? Or how much they might fade? This is all so recent that even if you did still have marks on your face afterwards, could you really know whether they'll be "disfiguring" in the future?
