A tattoo black tattoo on the upper torso, upper arm, forearm reached complete removal after 10 sessions at Removery over 6 years.

Before (session 0) and after (session 10) at Removery.
The tattoo
A medium black tattoo on the upper torso, upper arm, forearm, more than 10 years old when treatment began.
The forearm drains adequately but sits further from the major lymph nodes of the torso.
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
10 sessions at 12 weeks intervals accounts for roughly 108 weeks of active treatment.
The total reported duration was 6 years, which means roughly 201 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.
