Not really. You can always create an adhesive tattoo (and make several simmilar ones) and paste at the same place whenever you want.
It's a lot more easier and logic to do that then airbrush and hide everything at every sigle TV performance, concert, PV, photoshoot whatever.
We would surely have had much much more pictures of the "tatto" had it been real
