What is the best laser machine to remove blue ink?

The PicoSure laser is currently the best on the market for laser tattoo removal. Working 3x faster than all other lasers, it's also ideal for all skin types and tattoo colors. I would try to find a practitioner that has the PicoSure device and schedule a consultation. 
My best,

Thank you for your question. Picosure is the latest in
tattoo removal technology. Tattoos are made up of ink that has been placed into
the deeper layer of the skin, the dermis. This layer of skin is not shed like
the upper layers of your skin, but remains in place, which is what makes
tattoos permanent. In order to remove them, the cells that hold the ink have to
be removed. The Picosure laser is able to do this in fewer treatments then
older technologies, typically 4-8 sessions at 4-6 week intervals and has the
ability to treat multicolored tattoos with this same efficacy. I recommend
consulting with a qualified physician in your area for a full consultation.

The Picosure is a good option and gets a lot of press and media attention. I still prefer the Ruby laser for blue and light green ink. Be well, Dr. M
