Technically? Nothing.
But, as with anything, it’s about nuance. You can read through the ingredients here[0] and tell me what you’d like in your body.
The earliest tattoos, from my understanding, were done by incision and rubbing carbon into the wound. Regardless if you use old or new inks/techniques, it’s not really cut and dry to say “this is bad/good” because the size of the particulates matter. For a tattoo shop that uses high quality ink, and is diligent in its sterilization, most inks are fine. The large molecules are “trapped” by your immune system to just stay there[1], making them not dangerous.
There is a ton of research on PubMed about tattoos, most being negative. However, I suspect it’s because the authors had a predisposition to be negative from the start based on how the research is conducted and what they focus on. But I could be wrong and you should make up your own mind.
Bottom line: if you get tattoos, pay the premium and go to a good shop. The hygiene and good products are worth it, if that’s your thing.
