The tattoo
A full sleeve black tattoo on the 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.
