V-NISSG Proof of Competence: What You Need to Know

As of 1 June 2024, a new legal requirement applies in Switzerland:Anyone performing certain treatments with non-ionising radiation or sound must hold a proof of competence under V-NISSG. The courses are conducted by Lisandra Solange Wigert – LW Medical Beauty Fachschulen (an examination centre listed by the FDHA). EY Esthetic provides guidance on the requirements and the path to certification.

What is the V-NISSG?

The acronym stands for the Ordinance to the Federal Act on Protection against Hazards from Non-Ionising Radiation and Sound. In practical terms, this means that treatments using laser, IPL, and other regulated technologies may only be carried out by individuals who have obtained the corresponding proof of competence. The regulation aims to protect clients and practitioners alike.

How is the proof of competence structured?

The proof of competence consists of three modules, each building on the previous one.

Fundamentals Module This module covers the essential medical knowledge: anatomy, physiology, and pathophysiology of skin and hair, changes affecting skin, vessels, nails, and tissue, as well as the professional assessment of these structures.

Technologies Module This module addresses the technical foundations of all procedures subject to V-NISSG requirements. These include optical radiation sources such as laser and IPL, and, depending on the field, also radiofrequency, ultrasound, cryolipolysis, plasma, or shockwave.

BKF Module – Treatment-Specific Knowledge and Skills The BKF module is the most practice-oriented of the three. It focuses on the specific type of treatment for which the proof of competence is being obtained. There are seven different BKF modules in total, covering the various treatment categories.

Which path applies to me?

There are two training pathways, depending on prior qualifications.

Without relevant prior qualifications, you begin with the Fundamentals Module, followed by the Technologies Module, then the appropriate BKF module. The total training duration ranges from two to eleven days, depending on the proof of competence sought.

With relevant prior qualifications — for example, as a Kosmetikerin EFZ, Kosmetiker EFZ, or with a comparable professional qualification — the Fundamentals Module is generally waived. Training begins directly with the Technologies Module, followed by an extended BKF module that integrates the foundational content in a condensed form.

Do I have to repeat everything for each new treatment?

No. Modules already completed remain credited. Someone who holds the proof of competence for laser hair removal and later wishes to become certified for tattoo removal will, as a rule, only need to complete the relevant BKF module.
