Why do tatoos persist without spreading out or dissolving? That
is, why does the dye used stay within the cell? I wonder - if the cells
themselves are stained and cells are replaced periodically, why do not tatoos
disappear fairly rapidly? Two local tatoo parlors and a local tatoo-removing
doctor did not really have adequate answers.
I cannot say I am sure about this but I would guess that the dye

It is also everywhere in a body as a sort of fine net which helps hold things
