yeah i had some done in a place whrer i had scars which is generally a pretty bad idea
- but it looks cool where it does light up....i can find out for u- i'm guessing skin candy is the company of the in you're going to have?

I haven't heard of any negative side effects from modern UV ink. I myself have a UV tattoo on my arm and have never had problems with it, and I've had it for a couple years.
A lot of people though want to wait until it has been out for at least 10 years before they try it, that way they can be more certain that the inks are really safe, and that the inks don't slowly cause problems over the years. So all in all, it's really up to you whether or not you want to risk it.

i spoke to a tattoo artist nearby and he's got one on his face, he said that it was hard to get it to show up and required 3 sessions to get it done right and even then it was fading
