A tattoo white tattoo on the skin reached 75% fading after 8 sessions at Spa Halmstad over 2 years and 6 months.

After 8 sessions at Spa Halmstad.
The tattoo
A medium white tattoo on the skin, 1–5 yrs old when treatment began.
Timeline
8 sessions at 6 months intervals accounts for roughly 182 weeks of active treatment.
The laser
Spa Halmstad treated this case with the PicoPlus, a picosecond platform.
For white ink, it operates at 1064 nm with a pulse duration of 450 ps.
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.
