A large black tattoo on the forearm reached complete removal after 8 sessions at Fade Aesthetics over 2 years.

Before (session 0) and after (session 8) at Fade Aesthetics.
The tattoo
A large black tattoo on the forearm, 1–5 yrs old when treatment began.
The forearm drains adequately but sits further from the major lymph nodes of the torso.
Timeline
8 sessions at 8-12 weeks intervals accounts for roughly 84 weeks of active treatment.
The total reported duration was 2 years, which means roughly 19 weeks of gaps between sessions.
That spacing sits at the longer end of the accepted range, giving the lymphatic system more time to clear fragmented particles between passes.
The laser
Fade Aesthetics 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.
