Can laser remove white ink particles
Thanks for your question. Although you are correct in understanding that the laser is drawn to color specifically, not white, there is a mechanism by which the white ink particles can clear with laser tattoo removal. You mention that the white was mixed with black to create of course the gray. The laser energy will be absorbed by the target chromophore ( the black ink) and will selectively damage or destroy that chromophore through photothermolysis. However there is an additional photoacoustic effect (that's the popping sound you hear) which is capable of shattering nearby ink particles regardless of their color. This photoacoustic effect can result in the clearing of the white ink particles that are mixed with the black. Best, Lisa Vuich, MD
