Summary

\- For treating unwanted tattoos, the gold standard treatment is a nanosecond or picosecond laser. However, comparative microscopic analysis is limited. Therefore, the aim of the present study is to analysis morphological changes of tattoo particles and surrounding tissue in human skin.

Conditions

• Tattoo; Pigmentation

Interventions

Type	Name	Description
OTHER	picosecond laser treatment + measurement with a multiphoton tomography system	Patients with unwanted tattoos who plan a laser treatment will be recruited for measurements using a multiphoton-tomography system. These are scheduled 6 weeks and 12 weeks post-treatment.
