UV sensitive ink pigment?

    I don't start too many threads in chemistry, but I had an idea for something, and my chemistry knowledge is limited. I was just looking for a feasibility study.

    For the record, I hate tattoos. The reason I hate tattoos is that they are permanent, and I'm old enough to know that what is cool today, will be laughable tomorrow. <insert pic of Mac at aged 16 with "Billy Idol" hair> It's been trendy for the last 10 or so years to get tattoos. I think many people...especially those who chose to get "career ender" tattoos on their neck or other clearly visible areas will eventually regret them.

    Would it be possible to design a pigment in tattoo ink that could be sensitive to UV light? What I envisioned is a pigment that would slowly break down when exposed to daily UV light. Over time, daily exposure to the sun would slowly fade the tattoo away, or could be immediately removed with UV laser tech.

    Would such a thing be possible?

    Thank you in advance,

    over time, every tatoo fades (problem is often the people die first)

    Maybe, if the tattoo can be made of some fluorescence materials

    I work with light-sensitive dyes all the time, and there are many choices of dyes that break down over time when exposed to UV light (or even visible light). As for weather or not any of them are safe to inject under your skin, I have no idea.

    It's very possible, in fact most dyes breakdown when exposed to UV light, hence plastics fading etc.
