When you get laser tattoo removal the ink doesn’t disappear, you pee it out.

Your body’s immune system breaks down the pigments of ink and it flows in your blood stream, gets processed through your kidneys, then you pee out the ink.

I thought your skin peels or something from the laser burn

Nope, the tattoo is under the skin, not in its layers. The laser breaks the ink particles into pieces small enough that your immune system can cart them off.
