How does PicoWay laser tattoo removal work?

“PicoWay uses ultra-short picosecond laser pulses to shatter tattoo ink into tiny particles that the body's immune system can naturally eliminate. Operating at four wavelengths (1064 nm, 785 nm, 730 nm, and 532 nm), PicoWay targets the full spectrum of tattoo ink colors across a wide range of skin types.”
