IIRC, the skin whitening industry in Asia, which hawks products of very questionable efficacy, is worth tens of billions. I wonder how much a CRISPR solution would be worth, given that it has a better chance of working than snake oil in a soap.

Jokes aside, is it really as simple to administer as injecting one's self with a, as he calls it, plasmid?

No it is not that simple. You need a carrier to help the DNA get into cells efficiently. If you want to modify specific cell types then you need a cell type-specific carrier. Today, editing your DNA is "easy" -- targeting the right cells is "hard."

If he were injecting enough of something to actually cause the required DNA damage there would be necrosis at the injection site. If enough to have a systemic effect it would basically be chemo therapy. Whatever he is injecting is inactivated/diluted/etc.
