Thanks for your input! Since I'm considering a cover-up, I will have to do at least a few laser sessions anyways, so I'll definitely need to do a lot more research. The place I considered originally has a PicoWay. I'd be open to hearing opinions on different lasers. Mine is mostly shading with very light line work - artist specifically said she was using very light touch and there was such little pain I felt like I could have taken a nap. I'm hoping that might help reduce the number of sessions needed to fade. I have another tattoo with heavier line work, and that one felt like a razorblade slicing through the skin the whole time. After 10 years it looks very much the same. I'd say the line work on that one is at least twice as thick. Never regretted that one, always loved it, but then again it has a lot of significance as my late mother had a matching one.
It's interesting but not surprising to hear that you had a different response to the laser on different body parts. I wonder if it's just increased circulation in different areas, or if it's more complicated than that?
Of course I would love to be one of the very lucky few who do get almost complete removal (keyword almost), but my expectations have thankfully been lowered. I at one point strongly considered a chest piece but decided against it. I wouldn't be broken hearted to end up with them, after all I like them enough to have considered it for years, but since I ultimately decided against it, I'd obviously slightly prefer to not. It's anyone's guess why I went with that positioning this time. ¯\_(ツ)_/¯
