What's the right laser to remove my red ink tattoo?

This is an excellent question.  Our office specializes in laser tattoo removal. We use the Alex Trivantage laser which is an excellent option for your black and red tattoo.  The black ink can be removed precisely with the Q Switched 755nm or Q Switched 1064nm laser. The Alex Trivantage laser also converts the 1064 nm wavelength to a 532 nm wavelength via a process known as harmonic doubling with a potassium titanium phosphate (KTP) crystal.  This wavelength is designed to precisely target red tattoo and we get excellent results with this laser.
If you would like to learn more about the procedure I recommend an in person consultation with a board certified dermatologist with cosmetic training.

Our office specializes in laser tattoo removal. We continue to advocate the use of the patented Alex Trivantage as an excellent option for red tattoo removal. Best, Dr. Karamanoukian Los Angeles

PicoWay is a picosecond laser that is good for red tattoos.Picosure is not good for red inks.Enlighten is a dual wavelength 1064 nm and 532 nm laser that uses pulse durations at 2 nanoseconds and 750 picoseconds and targets red ink.Q swithced 532 nm nanosecond lasers are also good for red inks. 

There are three currently available picosecond lasers for use with tattoos. The PicoSure is a 755 nm picosecond device that does not work well with red ink, although it works well with other colors. The PicoWay and the EnLighten are 1064 nm-532 nm picosecond lasers that are approved for all colors, including red. It is not that pico does not work, it is the wavelength of the PicoSure that is not the best for red ink. In your case, the clinic should have been using the RevLite for the red ink.The Pico lasers are the hottest things right now in the laser business, but the three are all a little different, so make sure that you do your homework and go to the right clinic that will work with you with your tattoo instead of trying to only use the pico to generate income.

The Picosure wavelength is 755
nm, a red light and doesn’t work well on red ink – a green light laser like 532
nm would be the better choice. Revlite has this wavelength – maybe just go back
and ask them to retreat it with the appropriate wavelength. Having said this,
the Picosure is really great for green ink tattoos! And there are now
picosecond lasers with the wavelengths of 532 and 1064 but they have just
become available.

Red tattoos respond best to the 532nm wavelength which the PicoSure does not have.  Other picosecond tattoo removal lasers have 532nm capabilities including the PicoWay. - Dr. Keaney
