Hi everyone, first post. I'm trying to seek out some advice because I haven't found any info online. Hopefully the moderators will let me ask a question here! I got a half-sleeve over a period of two days. The front half healed nicely, but the back half.... not so much. It scabbed pretty heavily, leaked plasma for over a week, and my arm became swollen to my forearm. A few months later it has finally stopped itching, but I remain with two problems. One is that some of the colors, particularly the light green, became muddier, with a sort of reddish brown tint infused into it. The other, and bigger, problem is that several small scabs took some color with them when they came off. It has created these ugly grey spots in an otherwise very beautiful tattoo. My artist said that I would have to wait a year for the colors to settle before attempting a touch-up, but he seemed noncommittal about the feasibility of that kind of touch-up. Does anyone have experience with these colorless post-scab spots and is it a wise idea to get them recolored? Thanks :)
