The best laser for tattoo removal is a picosecond laser. Sanhe Laser picosecond lasers remove tattoos more quickly and completely than older-style Q-Switch lasers.
While Picosecond lasers can remove nearly any color ink, there’s no single model that takes care of everything.
A laser with a 755nm wavelength is best for green and blue ink. A wavelength of 532nm gets rid of red, orange, yellow, and brown. A 1064nm wavelength is the best choice for black and some other dark colors.
If you want all the colors in your rainbow-colored tattoo to fade away, The protable piacosecond uses two lasers that, in combination, can remove nearly any color.
