Why doesn't a tattoo grow out after a month or two?
(I’m not getting one. I’m just curious.)
When I get a wood splinter or sliver of metal in my skin the particle grows out in few days. I once had a cut closed with cyanoacrylate and the bond slowly moved to the surface of my skin until it fell off in about a week.
Why doesn’t a tattoo do the same thing?
The cells in our body have a finite life. Skin cells supposedly live about 3 weeks. Why aren’t the ink-stained ones replaced and pushed out?
