My pants and underwear react under ultraviolet light too.

I've been looking into getting a UV tattoo for a while. The ink is first of all a lot thinner than normal tattoo ink so you'll need a really good tattoo artist because its runny. It's also harder to come by so all that's to say it'll be expensive.

Secondly, they're not entirely invisible. It all depends on whether or not your scarring fades.

Other than that, still very cool and I still want one!

Somehow it seems like a bad idea to inject your skin with florescent chemicals.

I would hope that the dye used wont "wear out" within a few years and have a lesser reaction to UV light. Either way props to whomever first thought of doing this.

I have one of these blacklight tattoos. Its the dark mark from Harry Potter. The scaring is about 90% invisible now, you can't see anything unless you know exactly where to look, and even then, it just looks like a faint line or two. I have had the tattoo for about a year and a half now and it still glows just as bright as it did when I first got it.

You'd think it would be a bad idea to inject your skin with died chemicals as well, but I guess progress has got to be made.

This invention is going to be really awesome for when I invent my time machine that only travels back to 1996.

Arguments against UV tattoos

UV tattoo ink is not commonly known or used, as very few varieties of UV inks are approved for use in the US. It is also many times more expensive than regular tattoo inks. Some people have had reactions to ingredients in the ink, ranging from minor itching to dermatitis. Several UV inks are suspected carcinogens and allergens and at this time, no research has been conducted into the side effects of long term exposure. Although many people who have received black light tattoos have had physical effects on the skin, any ink could cause a reaction. This can be a result of not protecting the tattoo from UV rays within 3 months of receiving the tattoo process or by using scented cremes or lotions on the tattoo area. This can damage the ink, causing it to become a normal ink color in all light. In time, it may also not glow in black lighting. Clear/blue UV inks are known to yellow or turn slightly brown with sun exposure. Color/black UV inks are known to become colored in all lighting. Therefore, it might permanently appear as a regular tattoo.

Arguments for UV tattoos

Over recent years, as the formulas for UV inks have been improved upon, it has become more common to hear reports of success with little or no reaction.
Tattoos can be mostly invisible, suitable for those who may be restricted in their choice of tattoo placement (because of their profession, for example) who can then choose to show off the tattoo under UV or Black light lighting.

My upvote was also for the video that auto-played after this one, where a guy was getting a skeleton tattooed over himself in UV ink.

I have UV tattoos over my ENTIRE body! Tattoos up my leg. Tattoos down my arms. Tattoos on my tongue, eyelids, and nose! Tattoos covering each and every toe!! Tattoos on the irises of both eyes!! Tattoos the entire length of my penis and completely covering the head of my thingy!! Tattoos on each and every hair of my head!! ALL UV TATTOOS!!! The only problem I have experienced with this, is that I can't go to sleep under a UV light because of the incredible glow of ME!!!
