Lasers are used to destroy the
pigments in the tattoo. Tattoo ink is a colored liquid and when the
laser attracts to the color it crystallizes the ink...making it a hard
substance. The body recognises this crystal as a foreign object and
either digests (metabolises) it or pushes it out through the skins
surface, much like a splinter. At the same time trying to keep
scarring to a minimum.
The surface of the skin is
“transparent” to the laser beam while the heat of the laser focuses at
the precise level of the pigment. The pigment chars and breaks down
into small particles that are removed by the body’s immune system.
