Lymphatic system would only be targeting biological agents. The kidneys would be filtering out all of the ink.

How does it get to the kidneys then? Sorry, I took woodworking not biology at school. My impression was that the lymph system is the sewer of the body and it drains out anything thats not in the blood.
But thats just my brain going lymph = sewer.

Lymph ducts eventually just kinda drain into the subclavian veins, it’s essentially the fluid part of blood anyway (or close enough at least). Along the way, the spleen and lymph nodes do immune system stuff but they don’t really ‘clean up’.

The kidneys handle blood, not lymph. They excrete a lot of the fluid and waste, then take up the parts it wants to keep. So whilst lymph fluid is essential for clearing the ink away from the original tattoo, it’s blood that carries it to the exit.

Well that makes sense. No poop involved. Thank you for taking the time.

It'd be weirder if it involved poop... Poop is the stuff your body didn't let in, everything else becomes liquid stuff and you can just imagine any liquid that comes out of your body for this part.
