After a couple days, those mystery red marks are drying up and getting ready to peel, so it turns out they were burn marks which I guess means the laser was in fact hot! I never did develop one blister though.
I think the ink is officially unreachable :(
I am going on vacation soon, and I have decided to leave the tape and bandages off this time. If an annoying amount of ink shows through at the end of a good tan, one that is two years overdue, I will go back for more treatments, but I feel at this point I have come to a road block and need to do something different, which may be to accept the ink that remains in the deepest depths of my skin.
I know I should feel excited, but I always imagined not stopping treatments until I couldn't see a drop of the black ink. I also wonder will the skin stay hypo-pigmented as it is now? Or in the sun, will it hyper-pigment, such as brown clouds? Will there always be an outline to remind me of what was once there?
I guess I will find out soon...
