I'd price "Tattoos o' Power" as a -10% power modifier and call it a day. It's really nothing but -5% for mundane countermeasures (slicing off the tattoo) and -5% for Nuisance Effect (advertises that you have powers). It's certainly no more limiting than Biological (Powers, p. 26) or Superscience (Powers, p. 107), both of which are -10%. Unlike gadgets, tattoos are by default concealed under clothing and protected by armor, and aren't prone to being burned away by large-area damage any more than such damage chops off arms and legs. The real limitation is that somebody who gets a peek might later hold you down and do surgery on you, which is on a par with Biological or Superscience implants in a setting where hacking the skin off power-users is commonplace. In other settings, I must agree with whswhs: it's a special effect, worth zilch.
That said, do note that if such tattoos are magical or whatever, there's a further power modifier for that. So you could claim -20% for Magical Tattoos o' Power.
