UV / Glow in the dark tattoos

I've just realized that these kind of tattoos existed, I've seen some pictures and they look so gnarly! The ink doesn't show up unless its under a blacklight.
Does anyone have one of these tattoos or know anything about this sort of ink? it doesn't sound like they'd be very good for your skin

 

I have searched very long for UV active pigments that are suitable for the use on the body, as in bodypainting. And even for that use, there officially no pigments. So I doubt, that these UV tatoos are healthy.... because it's not only temporary on the skin, but permantent, in the skin....


I am not saying it can't be done, but it's probably not so good. Plus, the effect is probably only temporary.

 

ive seen a few black light tats.they dont look so good even in a black light.ive allso seen 3D tats,and they dont look good either. id stay with regular tat ink.
