A small black tattoo on the upper back reached 75% fading after 6 sessions at Removery over 6 months.

After 6 sessions at Removery.
The tattoo
A small black tattoo on the upper back, 5–10 yrs old when treatment began.
The upper back is close to major lymph node clusters, which aids clearance.
Older ink benefits from years of natural immune-driven fading: macrophages have been working on the particles throughout the tattoo's life, reducing effective density before treatment begins.
Timeline
6 sessions over 6 months.
Cost
Removery did not share a total cost. For reference, the average per-session rate in Portland runs $133 to $399, which would put a 6-session treatment in the $798 to $2,394 range.
The laser
Removery treated this case with the Picoway, a picosecond platform.
For black ink, it operates at 1064 nm with a pulse duration of 240 - 450 ps.
Mike from GO describes PicoWay as a monster on black ink, and it is his personal choice for black ink removal.
Bottom line
The last 5 to 10 percent of clearance is consistently the hardest phase: residual ink sits deepest, immune response slows, and the composition of what remains is unknown.
