Picoway or PicoPlus from Lutronic, For a tattoo that is 80% black, and the rest a mix or red and white?

For black and/or red ink, the pulse duration in the pico-second range doesn't matter much. Both lasers will be equally effective at removing those colors. The advantage of the PicoPlus is that it is capable of treating ink deeper in the skin than the Picoway. Best of luck.

Black tattoos are best treated with 1064 laser. The laser with shortest pulse, most power, largest spot size with be the safest and most effective laser for this tattoo. Both lasers have the 1064 nm laser. Both are 450 picosecond lasers and also have nanosecond capabilities too. However, PicoPlus has more power and larger spot. a larger spot will be able to get deeper ink and treat more safely. Red ink doesn't need high power and probably equal efficacy with both using the 532nm laser. White is tough for any laser and I can't guide you there. Both are good lasers with the PicoPlus being preferred in my opinion. As stated, the experience of the operator is very important too.

At our practice, we have had great results with the PicoPlus. PicoWay and PicoPlus are similar devices with subtle differences. The wavelength for the PicoPlus is good for treating the black inks. However, for the other colors in the tattoo, the PicoSure laser, another picosecond laser by Cynosure, would be effective. We would recommend a combination of lasers to address treatment. The PicoPlus and PicoSure each use different wavelengths so they each can target different colors in the tattoo more effectively.

I recommend choosing by practitioner and not by laser. Find an experienced physician, and go with whichever laser he/she has.
Best of luck!
