I have had one laser tattoo removal session to partially remove my tattoo. The treatment was effective in that a decent amount of ink was removed, however in its place I have been left with reddish brown stains which apparently is hemosiderin. I've read online that ironically the same type of laser used to remove the tattoo (and which caused the staining) can be used to break down the hemosiderin. Is this true? If so, what would be the optimum laser settings? I believe an Nd:YAG laser was used.
