After working on www.Bullseyetattoos.com competitive analysis, earlier this year, I learned a lot more about online tattoo sites than I ever thought I would. It’s like that with clients - when I take them on, I need to learn all about them. I even watched an episode or two of Miami Ink so I could better understand who gets a tattoo and why.
In this season’s Project Runway , designer Jeffery Sebelia has a big tattoo on his neck - makes him look like a Cardassian right out of Star Trek - The Next Generation. While that’s both good and bad it would be interesting if you could have a tattoo that is visible only when you want it to be - and is invisible the rest of the time.
Well…..something like that exists and I found it on The Cool Hunter

According to what’s written at The Cool Hunter:
"Always wanted a tattoo but afraid of what your boss will say? Thanks to a fascinating new technique you can cover yourself in body art and no one will be the wiser – unless they see you in the dark, which is the only time these tattoos are visible. The new technique uses blacklight reactive ink, which is reactive to UV light. It’s kinda freaky but imagine the fun you could have after dark".
I did some research on blacklight reactive ink : (blaklight tattoo ink is the more searched on term)
"Blacklight reactive ink is a great way to have a tattoo that no one can see but under the blacklight or to add a little something special to trip out your friends.
Really how safe is Chameleon Blacklight Tattoo Ink?
Given its extensive testing of FDA approval, with absolutely no adverse reactions to it in over ten years, it is all in the proof, this ink is most likely the safest ink ".
I would not say that either term is that popular - but it’s a very niche, cool thing and I would think it would attract very targeted traffic as there are few people who know about it - its new and novel idea. I suppose I would not mind having one of these types of tattoos myself - be kinda interesting what you could do with it, esp when your in the dark.
