You'd be surprised at the changes that are possible with interior prosthetics alone. Alos, consider that about half the adult population can wear makeup without being considered remarkable for doing so. You might figure out a dude with a fake beard easily, but have less success at assessing the wrinkly old lady behind him.
It’s true, but by the same token it is subtle makeup that wouldn’t even begin to fool facial recognition, even if they don’t use Near-IR/UV. Do you think you could toe that line of fooling the camera and the human? If so, I’ll buy it, as I said you’re experienced in this field and I’m not.
