Thank you for your question. For red pigment the 532 wavelength is ideal. I would recommend a laser that uses picosecond technology which is a more advanced technology. The PiQo4 laser has 4 picosecond wavelengths including 532. I have been practicing laser tattoo removal for 20 years and have 5 Pico wavelengths.

I have had great success with the Enlighten device to treat red tattoo ink specifically and other colors in general. More importantly, I would suggest you make sure you feel comfortable with the doctor's training and expertise in the procedure as that matters just as much as which device is used.
