The pigment used in eyebrow embroidery usually fades with time, but I understand that yours did not. In this case, you could try using a laser to remove the pigments.
In my practice, I use a Pico-second laser to remove such pigments. Pico-second lasers are the newest lasers promising fast and efficacious tattoo removal. A study compared the use of nanosecond and picosecond lasers for the treatment of black tattoos in human patients, all other parameters being equal, and reported tattoo removal to be more effective with the picosecond pulse duration.
The shorter picosecond pulse duration is able to better target the tattoo pigment causing increased "breakup" or fragmentation of the pigment.
Depending on the ink type and colour, a number of sessions, perhaps 3-6, spaced about 6-8 weeks apart, will be required. Do speak to your doctor to advise further on whether this is suitable for yourself and the costs involved. Thank you!
