PMU & Tattoo Entfernung
Treatment-specific knowledge for the laser removal of permanent make-up (PMU) and tattoos – device technology, pigment chemistry, treatment planning and safety requirements under V-NISSG.
About this module
The laser removal of permanent make-up and tattoos has been regulated by V-NISSG since 1 June 2024 and requires a specific competence certificate. This module imparts the knowledge for the safe and effective removal of PMU and tattoo pigments using laser technology: from the physics of laser pulses through the interaction with different pigment classes to correct treatment planning.
Learning objectives
- Explain the operating principle of Q-switched and picosecond lasers
- Select the appropriate wavelength for different pigment colours
- Carry out treatment planning including test treatment and interval spacing
- Recognise unwanted reactions (paradoxical darkening, scarring, hypopigmentation)
- Assess contraindications and document risk information
- Keep a complete treatment record in accordance with V-NISSG
