A common misconception about laser tattoo removal is that blue, green, and purple inks are impossible to remove (or at least very difficult to remove). While this is true for most other laser tattoo removal clinics (who do not have the proper wavelengths to target these colors), it is not the case at Erase The Ink MD. We have invested in the best and latest technology so that we can remove any color of ink on any color of skin as quickly as possible.
Our state-of-the-art Astanza Eternity ruby laser (with a wavelength of 694nm) is perfect for removing blue and green and purple inks as well as their shades of teal, turquoise, lime green, etc. It is also perfect for extremely stubborn blacks that other clinics cannot completely remove.
Just as every patient is different, every tattoo that undergoes laser tattoo removal is unique. Our goal at Erase The Ink MD is to remove all unwanted tattoos, regardless of the colors of ink in the design, and to do so, multiple laser wavelengths are needed to get the job done.
Based on the concept of light absorption, some tattoo pigments absorb some wavelengths of light better than others. To provide effective tattoo removal treatments, you’ll want to make sure that your tattoo removal clinic has the appropriate wavelengths that will be well-absorbed by the tattoo inks you’re removing.
Our goal is absorption. Tattoo removal works by breaking up the ink particles in the skin, which your immune system then clears away (i.e. the fading process). To achieve this, the laser is pulsed over the tattoo, directing light energy toward the ink. The energy is absorbed by the tattoo ink particles, which instantly break into microscopic fragments.
If the ink doesn’t absorb the laser light because an ineffective wavelength has been used, the ink doesn’t fragment and the tattoo won’t be removed. It’s as simple as that.
At Erase The Ink MD we use both the 1064nm and 694nm wavelength to treat blue, green, and purple inks. The 1064nm wavelength clears away any darkness or “mud” in the tattoo. Blues and greens will often contain darker pigments, especially dark blue tattoos, and we want to clear those away with the 1064nm wavelength because darker pigments absorb that wavelength best and we also want to use the appropriate level of energy that is safe for your skin. We will then use the 694nm wavelength to target lighter shades of blue and green. At each appointment we will determine which wavelength is best based on the response on your skin.
As you progress through removal, tattoos often change colors. Sometimes appearing darker at first because we have turned the larger ink particles into “sand”, and then gradually fading as you progress through your 6-12 treatments.
A Note About Other Wavelengths
There are some other wavelengths used for tattoo removal –- namely 585nm and 650nm. While these wavelengths also would be potentially good choices for removing blue and green inks in theory, they cannot be produced with the same energy as the wavelengths mentioned above.
The 585nm and 650nm wavelengths are created through the use of dye-impregnated hand-piece filters (read our article on why this is inferior technology here), which cause the energy levels to pale in comparison to those produced directly by a laser.
Beware of clinics telling you that they can remove your blue/green/purple tattoo with these wavelengths when they really can’t. They might be able to start the removal, but they won’t be able to complete the removal. We have many clients who have gone down this (expensive and frustrating) road only to come to Erase The Ink MD where we actually have the appropriate technology to remove these ink colors completely.
