At my center I typically will not perform laser tattoo removal of permanent or semi-permanent makeup. The main problem lies in the types of ink used in makeup tattooing. There is variability in the types of ink used, and it's hard (or sometimes impossible) to know what each permanent makeup practitioner uses. Given that you know iron was in the ink used in your microblading treatment I would advise against treatment as iron can turn black when treated with a laser, be it the PicoSure or others. As such, I find that the potential risks outweigh the benefits in proceeding with this type of treatment. The high risk of an outcome that is not desirable to patients simply isn't worth it in my opinion. Given that microblading is semi-permanent, my recommendation would be to give the makeup time to fade. While this may not be the quick fix you are looking for, I would hate to see you have a potential reaction to the treatment that is worse than what you presented with in the first place. Be patient and good luck!
In my four years of full-time laser tattoo removal I have found myself in something of an eyebrow subspecialty. It is a bit unusual to see titanium dioxide compounded into eyebrow inks, but nothing surprises me.Using my PicoSure, I have had excellent success with eyebrows. The oxidation behaviors from both inks in your brows should pose no significant problem with removal—just keep that pencil handy as you go through treatments. You’ll have some brick-red brows for a few months!It usually takes 2-4 PicoSure treatments spaced 8-12 weeks apart to remove miscrobladed brows.Best of luck to you!
