Before (session 0) and after (session 1) at Grand Rapids Tattoo Removal.
The tattoo
A large blue, brown, black and yellow tattoo on the forearm, 5–10 yrs 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.
The laser
Grand Rapids Tattoo Removal treated this case with the Picosecond, a picosecond platform.
For blue, brown, black and yellow ink, it operates at 1064 nm with a pulse duration of 300–750 ps.
