Laser Tattoo Removal
Tattoo removal is done by lasers that can break down the ink particles in the tattoo. The broken-down ink is then absorbed by the body,A tattoo laser emits a burst of energy within the given absorption spectrum of the pigment to provide a breakage of tattoo pigment. Some tattoos are black and blue but other coloured tattoo such as yellows, greens and fluorescent inks are more challenging to treat than darker blacks and blues, because they have absorption spectra that fall outside the emission spectra available in the tattoo removal laser.
Few coloured inks contain high concentrations of titanium dioxide which is highly reflective. Consequently, such inks are difficult to remove.
How does Tattoo removed by laser
Generally tattoos consist of thousands of particles of tattoo pigment suspended in the skin.Tattoo pigment particles are permanent because they are too big to be removed. Laser treatment causes tattoo pigment particles to heat up and fragment into smaller pieces. These smaller pieces are then removed by normal body processes.Laser tattoo removal is a successful application of the theory of selective photothermolysis (SPTL).
Complete laser tattoo removal requires 4-5 treatment sessions, typically spaced at least four weeks apart. At each session, some but not all of the tattoo pigment particles are effectively fragmented, and the body removes the smallest fragments over the course of several weeks. The result is that the tattoo is lightened over time.
A new technique using two to four passes with the laser, twenty minutes apart, caused more breaking up of the ink than the conventional method.
