A tattoo green and white tattoo on the upper arm reached 75% fading after 10 sessions at Skin workz over 3 years and 6 months.

Before (session 0) and after (session 10) at Skin workz.
The tattoo
A medium green and white tattoo on the upper arm, less than 1 year old when treatment began.
The upper arm is close to the axillary lymph nodes, which supports efficient clearance between sessions.
Fresh tattoos start at full ink density with no prior fading, so the laser encounters them at their heaviest point.
Timeline
10 sessions over 3 years and 6 months.
The laser
Skin workz treated this case with the Revlite SI, a nanosecond Q-switch platform.
For green and white ink, it operates at 650 nm with a pulse duration of 5 - 20 ns.
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.
