Before (session 0) and after (session 2) at treatment.
The tattoo
A medium black tattoo on the neck.
The neck has dense lymphatic tissue nearby, making it one of the more favorable locations for clearance.
Timeline
2 sessions over years, 8 months.
Sessions were spaced 4 weeks apart.
Cost
No total cost was shared. For reference, the average per-session rate in Fort Lauderdale runs $139 to $546, which would put a 2-session treatment in the $278 to $1,092 range.
The laser
The Medlite C6 is a nanosecond Q-switch platform.
For black ink, it operates at 1064 nm with a pulse duration of 5 - 20 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.
