Details and patient eligibility

About

• 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.

Enrollment: 20 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• healthy patients who plan a laser treatment of their unwanted tattoo/ tattoos at our department

Exclusion criteria

• laser pretreatment of their tattoos to be treated
• pregnancy, breast feeding
• open wound on the area to be treated
