Green, blue, and purple tattoo pigments are often the colors most resistant to laser removal. Recently, the first ever picosecond laser with a 785 nm wavelength was developed by Syneron Candela to improve the rate of clearance of green, blue, and purple tattoo inks. This is available for Picoway, the world’s most effective, and most safe laser system for tattoo removal with minimal to no recovery time.
Please see an article on the PicoWay 785nm handpiece written by Dr. Bernstein & co:
In this first study of the new 785 nm picosecond laser, results demonstrate safe and effective removal of multicolor tattoos. Although clearance was shown for a multitude of colors including black, the 785 nm laser wavelength has a special affinity to purple, blue and green tattoo pigments.
