Alexandrit + Nd:YAG in a dual device is an established technology combination for 2026
Only this combination covers all skin types I–VI safely and effectively — anything else is a compromise. We work exclusively with dual-laser platforms (Lutronic Clarity II and DEKA Again Pro) and deliberately avoid single-wavelength devices.
Why the choice of device makes all the difference
When it comes to laser hair reduction, the result depends heavily on the device, alongside the practitioner's expertise. Professional laser systems are active class IIb medical devices under the EU Medical Device Regulation (MDR 2017/745) and differ in five critical dimensions: wavelength, maximum energy density (fluence), pulse duration, repetition rate and integrated skin cooling.
All these factors influence how reliably the device matches different skin and hair types, how comfortable the treatment is for you, and how predictable the results are across multiple sessions. A device that only uses one wavelength inevitably only covers part of the Fitzpatrick scale. A dual-laser platform with Alexandrit (755 nm) and Nd:YAG (1064 nm) objectively covers the entire spectrum — from very light (type I) to very dark skin (type VI).
We deliberately chose two platforms for our studios: the Lutronic Clarity II and the DEKA Again Pro. Both are dual-laser platforms. We don't use single-wavelength devices — they wouldn't live up to our promise of effectively treating all skin types.
Lutronic Clarity II — 755 nm Alexandrit & 1064 nm Nd:YAG
The Clarity II by South Korean manufacturer Lutronic is one of the most widely used premium platforms in Europe. The device is approved as a class IIb medical device and combines Alexandrit and Nd:YAG wavelengths in a single unit. Wavelengths are switched via a control on the handpiece — without changing devices or interrupting the session.
The Clarity II is our daily working platform in the Berlin studios. It's approved for Fitzpatrick types I to VI, and your practitioner selects the wavelength based on your skin type and treatment area.
DEKA Again Pro — dual-laser platform from Italy
The DEKA Again Pro comes from the Italian manufacturer DEKA (El.En. Group) and is also a Class IIb dual-laser platform. It's used in our studios in München-Haidhausen and Augsburg. Technically, it follows a similar logic to the Clarity II, but relies on a different handpiece architecture and larger spot sizes for large treatment areas.
| Parameters | Lutronic Clarity II | DEKA Again Pro |
|---|---|---|
| Wavelengths | 755 nm (Alex) + 1064 nm (Nd:YAG) | 755 nm (Alex) + 1064 nm (Nd:YAG) |
| Medical device class | IIb (MDR 2017/745) | IIb (MDR 2017/745) |
| Spot sizes | 6–18 mm | up to 22 mm |
| Repetition rate | up to 5 Hz | up to 10 Hz |
| Integrated cooling | ICD cold air connection | Contact & cold air cooling |
| Main application | All-rounder · precise areas | large areas, speed |
| Fitzpatrick spectrum | I–VI | I–VI |
Both platforms undergo annual maintenance and safety checks. We're happy to provide the equipment documentation if you're interested.
Cooling technology — three established principles compared
During the laser pulse, the epidermis briefly heats up due to the absorbed energy. Effective cooling serves two purposes: it noticeably reduces the sensation of heat for you and protects the top layer of skin from unnecessary thermal stress. This is especially relevant for skin types III–VI.
| Cooling principle | How it works | Strength | Things to note |
|---|---|---|---|
| Contact cooling (sapphire plate) | Pre-cooled sapphire or glass plate rests on the skin during the pulse | direct skin contact, precise cooling of the epidermis | handpiece must be in full contact; hygiene management required |
| Cryogen spray (DCD/ZRF) | Burst of coolant immediately before the pulse | very precise timing of spray–pulse | coolant consumption; cold sensitivity in some patients |
| External cold air (up to –30 °C) | Continuous stream of cold air onto the area | no skin contact, hygienic, comfortable for sensitive areas | separate device required; background noise in the studio |
In our studios, we primarily work with external cold air cooling up to –30 °C. The cooling is coordinated with our handpieces and is consistently used during every session. It's impossible to say across the board which cooling system is "better" or "worse" — what matters is that it suits the laser system and is applied reproducibly.
Medical device class IIb & MDR
Since May 2021, the EU Medical Device Regulation MDR 2017/745 has been in effect. Lasers for hair removal are considered active therapeutic medical devices and fall under the IIb classification — medium risk potential. This has specific consequences:
- CE marking required: the device may only be used in the studio with a valid declaration of conformity and testing by a notified body.
- Documentation required: manufacturer documents, maintenance logs and safety checks must be kept on hand.
- Vigilance reporting: serious incidents must be reported to the Federal Institute for Drugs and Medical Devices (BfArM).
- Qualified staff: see NiSV in the next section.
NiSV — the specialist qualification for laser users
Since 1 January 2021, the Ordinance on Protection against Non-Ionising Radiation (NiSV) has regulated the use of cosmetic laser and IPL devices in Germany. Key regulations:
- Proof of expertise: at least 120 teaching hours with a final exam at a recognised training centre.
- Application documentation: medical history, parameter settings and aftercare are documented in writing.
- Keep proof on hand: the specialist certificates must be available in the studio and shown to the authorities on request.
All practitioners at Laserazor have acquired this qualification — the certificates are visibly displayed in the studios. The NiSV isn't a hurdle, but a protection for you as a customer.
Checklist: how to spot a well-equipped studio
Our four studios in Berlin, München and Augsburg
We run four NiSV-certified studios, all equipped with Class IIb dual-laser platforms. While the locations and teams vary, the laser technology and treatment protocols are exactly the same.
- Berlin Pestalozzistraße (10625 Charlottenburg) — Lutronic Clarity II
- Berlin Danckelmannstraße (14059, near Ku'Damm) — Lutronic Clarity II
- München Haidhausen (81667, Steinstraße 57) — DEKA Again Pro
- Augsburg Rathausplatz (86150) — DEKA Again Pro
We use external cold air cooling in all our studios. You'll find an overview on the location page.
