I’ve just had PicoSure laser removal for my eyebrows and it turned gray! Which laser can get rid of this problem? (photo)

I see a lot of poorly-done eyebrows in my practice. The popularity of permanent makeup has attracted many unskilled tattooers and poor results. The wide variety of pigments used complicates the removal process, and it’s very important to find a medically trained laser practitioner with a lot of experience with permanent makeup.
Depending on ink type(s), application methods, and tattooing depth, removal can take anywhere from 1 to 5+ treatments. During the treatment process, it’s common to see color changes such as yours.
Your situation is simple: You need more treatments with the PicoSure. With a double application of brows (the older being an oxidizing iron pigment) you should expect to undergo several more treatments for full removal. I can think of no better laser for the job than a picosecond machine.
Best of luck to you!

Agree with Dr Berman- due to the unknown pigment and lack of understanding I do not treat eyebrows. Oxidation of iron and ti. oxides can lead to this. Your therapist will know what to do- namely retreat, - 755 will be ok, if it runs out of power even with boost, goto the older nano at 1064. All the best, Dr Davin S. Lim. Brisbane. Australia. 

i am a huge fan of the Picosure laser. however due to metal in the ink used to tattoo the eyebrows, we avoid doing any treatments on them since the results can lead to color changes that i believe are not correctable. The Picosure laser is the best laser for body tattoos but we avoid treating eyebrows or lip tattoos.david berman md
