Introduction: A major mechanism of tattoo removal is laser assisted fragmentation of these particles, which are then transported away from the skin. For many years, Q-switched lasers with nanosecond pulse durations at high light intensities have been applied to cause such fragmentation via rapid heating up while sparing the adjacent tissue.
Materials / method: Despite the long-lasting use of such laser treatment, the exact mechanisms of laser assisted fragmentation are hardly investigated. And thre new role of the macrophage is essential and will explain in this topic.
Results: Due to short and intense laser pulses applied, non-linear effects of light (e.g. photoacoustic and optical breakdown) and nonlinear thermal properties in tattoo particles may play a crucial role.
In the past few years, lasers with even shorter pulse duration in the sub-nanosecond range were launched for tattoo removal.
Conclusion: Theoretical considerations assumed that pulse durations shorter than nanoseconds allow even more effective fragmentation of tattoo particles but is it really true ? Does it make really difference with the « old » nanosecond when you discuss cost, maintenance and result. Not sure...
