The tattoo
A half sleeve blue, orange, purple, green and yellow tattoo on the shoulder, upper arm on Type II skin (fair, tans sometimes but often burns).
Fitzpatrick Type II is favorable: tolerates standard energy settings with minimal pigmentation risk.
The upper arm is close to the axillary lymph nodes, which supports efficient clearance between sessions.
