A medium black tattoo on the shoulder reached 25% fading after 4 sessions over 4 months.

After 4 sessions at treatment.
The tattoo
A medium black tattoo on the shoulder on Type II skin (fair, tans sometimes but often burns).
Fitzpatrick Type II is favorable: tolerates standard energy settings with minimal pigmentation risk.
The shoulder has good proximity to the axillary lymph nodes, supporting clearance between sessions.
Timeline
4 sessions at 6-8 weeks intervals accounts for roughly 21 weeks of active treatment.
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.
