Can the PicoSure laser remove white ink?

It is really hard to tell without any photos, from my experience no tattoo removal laser will remove white ink, they are all made to target pigment. The other 95% of the tattoo which is black can definitely be removed with a tattoo removal laser, however, it will take a series of treatments. I recommend getting a formal evaluation with a laser tattoo removal expert. If it's new, you'll want to wait until it's completely healed (around 4-6 weeks). I hope this was helpful. Best, Dr. Emer

In most cases, white ink will turn into a brownish dark color after being hit by a picosecond laser on 1064nm wavelenth. After that, the laser sees the pigment (brown) and can start to fade the ink. I see a lot of white ink and haven't had any trouble making it very difficult to see after laser treatments. I make no promises it will go away with treatment, but it will be negligible after some treatments. Best of luck.

Sorry for the vague answer but it depends on what the while ink is made of. If the ink used contains titanium oxide - the ink can be removed. What will actually happen is the white areas will turn dark (grayish) when hit with the 1064 wavelength. This ink can be removed - though it can be a slow process. You could have your provider do a trial spot to see if it will work. 

Laser removes tattoo by targeted and shattered up ink pigments from the skin, releasing it into the bloodstream to be flushed out by the immune system through the liver within 8-10 weeks.  The number of treatment is depending on various factors (cover up vs complete removal, laser technology, physician's experience, tattoo size, ink saturation, colors, overall health, skin type, tattoo location, etc.).  Black and Grey ink is the easiest to remove since dark color would absorb light energy more readily (black T-Shirt during the summer) than lighter color such as white. The less absorbtion of light based energy, the less ink pigments are being broken down. As always, seek laser tattoo removal treatment from a reputable professional healthcare provider in your area who is specialized in tattoos removal using both Nano/Pico laser technology.
