10 sessions over 2 years.
The laser
Laser Removal Clinic treated this case with the PicoSure, a picosecond platform.
For black, blue, green and yellow ink, it operates at 755 nm with a pulse duration of 550 - 750 ps.
For black, blue, green and yellow 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.
