The PicoWay® laser system delivers high peak power and ultra-short pulse durations for a photoacoustic effect that transforms skin from the inside out. With this remarkably innovative picosecond laser, you can treat a wide range of tattoos. Even difficult-to-treat blue and green tattoos. Picoway works by shattering tattoo ink into miniscule particles breaking it down so much that it is not visible to the naked eye. For optimal results and depending on the colours in the tattoo, 6-9 treatments are recommended.
