Tattoos Affect Your Immune System in Ways We're Only Beginning to Understand (www.sciencealert.com)

Once tattoo ink enters the body, it does not stay put. Beneath the skin, tattoo pigments interact with the immune system in ways scientists are only just beginning to understand.

Tattoos are generally considered safe, but growing scientific evidence suggests tattoo inks are not biologically inert. The key question is no longer whether tattoos introduce foreign substances into the body, but how toxic those substances might be and what that means for long-term health.

tbf there does seem to be some immune system weirdness with tattoos and if you're already in a higher than normal inflammatory state because you have an untreated autoimmune disease like celiac, maybe it could make you feel like shit at least in the short term. idk

I want a tattoo but paused my decision after learning that getting a tattoo causes inflammation and that this has a significant chance of causing flare ups in people with psoriasis. I have psoriasis. I also have other health conditions and should avoid inflammatory triggers in general. Sucks. I only want a very small tattoo, though, so we'll see. Maybe someday.

%100 can see that, but these articles keep coming up like they've nailed down that people with tattoos are more sick than people without. Which is a correlation doesn't equate cause....and everyone is running with it now.
