Q - Switch is a from the laser in the media suddenly release all of the activation state of the energy from the second pulse laser technology. Exposure to the laser to the white response. In addition, the appropriate use of this laser, scar formation of risk less than 4.5 per cent. In one study, such as Leuenberger found Q - Switch to blue-black tattoo, with the highest rate of clearance, but it can also have a long-term color and missing the highest rate of occurrence. Another side, Nd: YAG laser is not pigments and missing.


tattoo, remove the laser theory
a) The most basic view is that laser is tattoo pigments absorption, because these pigments are in a variety of colors, and therefore need to be multi-wavelength laser to remove tattoos. Using the laser to remove most of the "visible" color, and/or change the color pigments, These pigments used at the start of the laser is invalid. This has led to a tattoo, it is very difficult to deal with.


b) wavelength is longer PENETRATE THE SKIN deeper and less divergence. In addition, wavelength, spot size also determines the laser cross-cutting depth. The edges will be diffused, and therefore reveals the Plena divergence rate high, and they cannot reach skin deep. For this reason, in the tattoo application when the spot to replace increase energy. Because the increase of energy major role in shallow, leading to greater damage and scar formation.
