Over the millennia that the history of tattoos has, little has changed: each tattoo is an engraving of a wound in an unchanged form with ink.

But many elements of tattoos remain, paradoxically, mysterious and enigmatic. scientists are still not sure what causes some tattoos to fade quickly and others that are “temporary” to stay longer even though they should. The reaction to light also remains unclear.

In general, these cells are effective in healing burns and healing skin scars, except when ink is involved. Pigment particles are bulky and difficult for immune system cell enzymes to break down.

Therefore, when the ink “gobbled up” immune system cellsHow macrophages that live in the skin (which spend their lives ingesting pathogens and cellular debris) turn into a tiny, gum-like mass.

However, Lynn cautions that even at best, any possible (or unlikely) benefit from a tattoo will have its limits. “I don’t think it will help cure a cold” or anything like that, he says.
