After 7 sessions at Laser by Nicole.
The tattoo
A medium black tattoo on the skin, 1–5 yrs old when treatment began.
Timeline
7 sessions over 3 years.
Sessions were spaced 4 weeks apart.
The laser
Laser by Nicole treated this case with the Switch, a nanosecond Q-switch platform.
For black ink, it operates at 1064 nm with a pulse duration of 10 ns.
Bottom line
The last 5 to 10 percent of clearance is consistently the hardest phase: residual ink sits deepest, immune response slows, and the composition of what remains is unknown.
