A large black and green tattoo on the upper arm reached 50% fading after 2 sessions at Miami ink off over 7 years.

Before (session 0) and after (session 2) at Miami ink off.
The tattoo
A large black and green tattoo on the upper arm on Type II skin (fair, tans sometimes but often burns), 5–10 yrs old when treatment began.
Fitzpatrick Type II is favorable: tolerates standard energy settings with minimal pigmentation risk.
The upper arm is close to the axillary lymph nodes, which supports efficient clearance between sessions.
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
2 sessions at 10-12 weeks intervals accounts for roughly 11 weeks of active treatment.
The total reported duration was 7 years, which means roughly 350 weeks of gaps between sessions.
That spacing is within the generally accepted 6 to 12 week range.
Cost
Miami ink off did not share a total cost. For reference, the average per-session rate in Miami runs $168 to $468, which would put a 2-session treatment in the $336 to $936 range.
The laser
Miami ink off treated this case with the Enlighten, a picosecond platform.
For black and green ink, it operates at 1064 nm with a pulse duration of 660 ps, 750 ps & 2 ns.
