The essentials at a glance
- The NiSV has applied nationwide since 31.12.2020. For hair removal with laser and IPL, specialist qualifications are mandatory.
- In NRW, enforcement is handled by the district governments (occupational health and safety). Commercially operated lasers for hair removal must be registered before use.
- With the right qualifications, beauty and laser studios can also remove hair. Treatments that intentionally damage tissue are strictly reserved for doctors.
- Things you can check: proof of qualifications, device type and wavelength, laser safety goggles, skin type check, consultation, and test pulses.
- Without the right qualifications, the risks increase: incorrect energy settings can cause burns and pigmentation changes, according to the Federal Office for Radiation Protection.
Who is allowed to offer laser hair removal in NRW?
In NRW, you can only remove hair with a laser or IPL if you can prove you have the specialist qualifications required by the NiSV. Anyone operating a laser for hair removal commercially must also register it with the relevant authority before use. The district governments are responsible for enforcement in NRW.
| Topic | What applies | Source |
|---|---|---|
| Validity | nationwide, including in NRW, since 31.12.2020 | NiSV |
| Qualifications | Mandatory for hair removal with laser and IPL | NiSV |
| Reserved for doctors | treatments that intentionally damage tissue are reserved for doctors, hair removal is not one of them | NiSV |
| Enforcement | the responsibility of the federal states, in NRW the district governments as part of occupational health and safety | BMUKN |
| Registration | anyone operating a laser for hair removal commercially must notify the relevant authority before starting operations | NiSV |
That's really all you need to know for most questions. This guide explains these key points one by one, and then shows what you can check yourself before your first session. We've deliberately left out the legal jargon and fines: if you need the exact legal details, you can read the original regulation or contact the relevant authority.
What the NiSV regulates
The NiSV is the regulation protecting against the harmful effects of non-ionising radiation when used on humans. It regulates who is allowed to use lasers and IPL on people, and has been in effect across Germany since 31.12.2020.
This clunky name refers to radiation like the light from a laser or an IPL flash lamp. These devices work because the hair pigment absorbs the light and converts it into heat (Ibrahimi et al. 2011). It's exactly this heat that can damage the skin if the settings are wrong. The Federal Office for Radiation Protection lists redness, pigmentation changes, and burns as risks of using the wrong energy levels, and recommends that treatments are carried out by qualified professionals (BfS).
That's why, since 31.12.2020, the following applies: proven expertise is mandatory for hair removal, whether in a clinic, a chain, or a small beauty studio. The Federal Ministry for the Environment explains exactly which treatments the regulation covers in its Q&A on the NiSV (BMUKN).
Qualifications: what they mean and who needs them
The NiSV qualification is proof for the person operating the device: anyone removing your hair with a laser or IPL must have it.
NiSV qualification means that the person treating you has proven they are qualified to use lasers or IPL for hair removal. Since 31.12.2020, no one is allowed to remove hair with these devices without this proof.
What's important for you: it's not enough for just anyone in the studio to have the qualification. The person actually treating you is what matters. The Federal Ministry for the Environment outlines what the qualification for cosmetic laser treatments includes. We won't list the number of hours or course contents here; you can find those details in the regulation and the ministry's explanatory notes.
At Laserazor, 16 specialists with the NiSV qualification work in our existing studios. For the new studio in Düsseldorf, opening in January 2027, Laserazor is also looking for specialists with the NiSV qualification. You can find our open positions under Careers.
Beauty studio or doctor's clinic: where the medical restriction begins
Hair removal with laser and IPL is also allowed in beauty and laser studios, provided they have the right qualifications; under the NiSV, treatments that intentionally damage tissue are strictly reserved for doctors.
The medical restriction means that certain treatments can only be carried out by doctors. Under the NiSV, this applies to treatments that intentionally damage tissue, not to hair removal.
So you don't have to go to a doctor's clinic for hair removal. However, there are still good reasons to see a dermatologist: a skin condition in the treatment zone, medications that make your skin sensitive to light, or sudden heavy hair growth that should be checked by a doctor. Find out more in our guide on hirsutism and hypertrichosis.
One difference is the billing. Dermatologists bill laser hair removal as a self-pay service according to the medical fee schedule, usually around 90 to 150 € per session for underarms, often without package discounts. Laserazor works with fixed prices per complete zone, which are the same across all studios. You can find a detailed comparison in our guide: Dermatologist or laser studio.
Notification before use: the requirement for the device
Anyone operating a laser for hair removal commercially in NRW must notify the relevant authority before using it; in NRW, the Bezirksregierungen are responsible.
So the specialist qualification applies to the person, while the notification applies to the device and the operator. Notifying means registering: the operator tells the authority they are starting to use this kind of laser. This applies to every studio in NRW that wants to use a new laser for commercial hair removal, whether it's in Köln, Aachen or Düsseldorf.
Who is responsible in NRW
In Nordrhein-Westfalen, the enforcement of the NiSV lies with the Bezirksregierungen, in the occupational health and safety department.
The regulation itself is federal law, but its enforcement is up to the states (BMUKN). For you, this means one simple thing: the rules for laser hair removal are exactly the same in Aachen, Bonn, Dortmund, Essen, Köln and Düsseldorf. Which authority is responsible for a specific studio depends on its location.
If you have doubts about an offer, first ask the studio about their qualifications and the device. If you're still unsure, the relevant Bezirksregierung is the right place to go. Also, if you get blisters, severe pain or lasting discolouration after a treatment, you need to see a dermatologist.
What you can check yourself before your first session
You can check six things yourself before your first session: the proof of qualification, the device type, the laser safety goggles, the skin type check, the consultation and the test pulses.
- Ask to see proof. Ask if the person treating you has the NiSV qualification, and ask to see the certificate. A reputable studio won't have a problem with this.
- Device type and wavelength. Ask whether it's a laser or IPL and what wavelength the laser uses. Alexandrit works with 755 nm, diode with 800 to 810 nm, Nd:YAG with 1064 nm (Ibrahimi and others 2011).
- Laser safety goggles. Both you and the specialist must wear safety goggles throughout the entire treatment. If they're forgotten, that's a red flag.
- Skin type check. Before your first session, your skin type will be determined on a scale of I to VI according to Fitzpatrick 1988. This includes questions about recent sun exposure, fake tan, medication and skin conditions.
- Consultation. You'll find out about the risks, how to prepare, what to keep in mind afterwards and how many sessions are realistic: 8 to 12, spaced six to eight weeks apart.
- Test pulses. Before the actual treatment, the specialist will do a few test pulses and then set the energy level.
A practical tip: ask these questions on the phone or by E-Mail. If they can't name a wavelength on the phone or dodge questions about their qualifications, they'll rarely do better in person. For Laserazor, our booking team will answer them on 030 310 13 860. You can find a detailed checklist with all the criteria in our guide Best laser hair removal in Düsseldorf: Checklist.
Laser, IPL, diode: the rules
For all hair removal devices, whether Alexandrit, diode or Nd:YAG lasers or IPL, the NiSV requires the person performing the treatment to hold specialist qualifications. We explain the notification requirement before use here for lasers.
| Device | What it is | Wavelength | Rule of thumb for skin | Specialist expertise according to NiSV | Notification before use |
|---|---|---|---|---|---|
| Alexandrit laser | Laser with a fixed wavelength | 755 nm | light to medium skin | Required | yes, for commercial use |
| Diode laser | Laser with a fixed wavelength | 800 to 810 nm | depending on the device, sits between Alexandrit and Nd:YAG | Required | yes, for commercial use |
| Nd:YAG laser | Laser with a fixed wavelength | 1064 nm | dark and tanned skin, considered the safest choice for dark skin types | Required | yes, for commercial use |
| IPL | Flash lamp with a broad light spectrum, not a laser | no single wavelength | depending on the device and filter | Required | ask the provider |
A studio with Alexandrit and Nd:YAG can choose the wavelength to suit your skin type. Laserazor uses both wavelengths in all studios, including the new studio in Düsseldorf, with cooling right before every pulse. Our guide Alexandrit oder Nd:YAG explains which wavelength suits which skin type, and you can find the difference to IPL on the IPL-Haarentfernung page.
Risks of lacking expertise
The Federal Office for Radiation Protection lists redness, pigmentation changes and burns from incorrect energy settings as risks of an improperly adjusted treatment (BfS). Without the right expertise, the knowledge needed to avoid these mistakes is often missing.
| Error | Possible consequence | How expertise prevents this |
|---|---|---|
| Wavelength doesn't match skin type | Burns, pigmentation changes | Skin type check, Nd:YAG for darker skin |
| Energy too high, no patch test | Burns | Test pulses before the first treatment |
| overlooking recent sun exposure or fake tan | Pigmentation changes | Asking about sun exposure, no sun on the area for two weeks beforehand |
| no or weak cooling | more heat on the skin's surface | Cooling immediately before each pulse |
| no safety goggles | eyes unprotected | Laser safety goggles for you and the specialist |
This is exactly where the NiSV comes in: specialist expertise should ensure that the device, wavelength, and energy suit your skin. Cooling and choosing the wavelength according to skin type are also described in the review by Ibrahimi et al. 2011 as key points for a safe treatment. During your consultation, ask what reaction to expect after the session and when you should get in touch. Blisters, crusts, or spots that don't fade need to be seen by a doctor.
You can do a lot to help: no waxing, epilating, or plucking for four weeks beforehand, no sun and no fake tan for two weeks beforehand, and no creams or deodorants on the area on the day. Afterwards, on the day of treatment, no sports, no sauna, no sun, and SPF 50 for two weeks. Find out more under Safety and Preparation and aftercare.

Frequently Asked Questions
What is the NiSV?
The NiSV is the regulation protecting against the harmful effects of non-ionising radiation when used on humans. It regulates who is allowed to use laser and IPL on people. For hair removal, certified expertise is mandatory, while treatments that intentionally damage tissue are strictly reserved for doctors.
When did the NiSV come into effect?
Since 31.12.2020, nationwide and therefore also in Nordrhein-Westfalen. Since then, no one has been allowed to remove hair with laser or IPL without certified expertise.
Who monitors the NiSV in NRW?
Enforcing the NiSV is up to the federal states. In Nordrhein-Westfalen, the district governments are responsible for this under occupational health and safety. The exact authority responsible for a specific studio depends on its location.
Can beauty studios in NRW offer laser hair removal?
Yes, as long as the person performing the treatment has the certified expertise required by the NiSV. Hair removal is not restricted to medical professionals. Under the NiSV, only treatments that intentionally damage tissue are reserved for doctors.
Does the NiSV also apply to IPL?
Yes. Certified expertise is mandatory for hair removal with both laser and IPL. Even though IPL uses a broad-spectrum flashlamp rather than a laser, the expertise requirement still applies.
How can I tell if a studio has the required expertise?
Ask to see the certificate of the person treating you. You should also look out for a specified wavelength, laser safety goggles for both you and the specialist, a skin type check, a consultation about the risks and test pulses before your first treatment.
Does a laser for hair removal need to be registered?
Anyone using a laser for commercial hair removal must notify the relevant authority before putting it into operation. In NRW, the district governments are responsible for this. The registration applies to the device and the operator, while the certified expertise applies to the person performing the treatment.
What can happen if your treatment is done without the right qualifications?
The Federal Office for Radiation Protection lists redness, pigmentation changes, and burns from incorrect energy settings as risks. Typical causes include using a wavelength that doesn't match your skin type, setting the energy too high without test pulses, and ignoring recent sun exposure. If you get blisters or spots that don't fade, you need to see a dermatologist.
Which laser is safe for dark skin?
For dark skin types, the Nd:YAG laser at 1064 nm is considered the safest choice, according to a 2011 review by Ibrahimi and colleagues. Alexandrit at 755 nm is ideal for light to medium skin. Laserazor uses both wavelengths in all studios, including in Düsseldorf from January 2027.

This guide provides general information and doesn't replace medical advice, diagnosis or treatment. Laser hair removal is a cosmetic procedure; if you have skin conditions, take medications that increase light sensitivity, are pregnant or have unexplained hair growth, it makes sense to get medical advice first.
