Before (session 0) and after (session 13) at treatment.
The tattoo
A full sleeve black tattoo on the upper arm, forearm.
The forearm drains adequately but sits further from the major lymph nodes of the torso.
Timeline
13 sessions over 3 years.
At 13 sessions, the treatment ran longer than the typical 8 to 12 session range for a standard tattoo, which is consistent with the case variables.
The laser
The PicoSure is a picosecond platform.
For black ink, it operates at 1064 nm with a pulse duration of 550 - 750 ps.
PicoSure's black ink adapter (1064nm) is considered largely ineffective by most experienced providers; the native 755nm is its strength.
