When the ink reaches the dermis, something strange happens. Your body is shocked by the unknown substance and actually wants to remove it as much as possible right away. The pigment particles are too large to be removed by the body's own clearing cells.
To still 'protect' you, the dermis encapsulates the ink.
This protective reaction literally creates spheres
ink, which can cause no further damage and therefore
the colors stay in your skin beautifully and permanently.
