My eyebrows were tattooed dark brown and have turned greenish blue. Can they be lasered?

Try to find a practitioner who uses the PicoSure device. It is hands down the best laser out there for tattoo removal, working 3x faster than all other lasers. It's ideal for all skin types and ink colors. My best,

Laser tattoo removal is an option for removing unwanted permanent makeup. I would recommend a test spot since often times multiple pigment colors are mixed together to achieve a certain shade, and once treated the pigment can sometimes change colors. This will help the provider determine what wavelengths need to be used. I have 5 Pico lasers which are gold standard for tattoo removal and with these advanced technologies it is possible to remove 96% of pigment colors.Dr. Daniel Ritacca

There are different wavelengths 755.1064 , 532.Tests can be done with different wavelengths to see effect of laser before proceeding with complete treatment.
