Radiofrequency (RF) skin tightening has become an important category in non-invasive aesthetic medicine, particularly for patients seeking firmer, smoother-looking skin without surgery or significant downtime.
Two Korean-developed systems attracting increasing attention in this category are FORKERT og Volnewmeter.
Both use monopolær radiofrekvensenergi to generate controlled thermal effects within tissue, but their technical approaches are different.
The most important distinction is straightforward:
- XERF uses two RF frequencies: 6.78 MHz and 2 MHz.
- Volnewmer uses 6.78 MHz monopolar RF.
However, frequency alone does not determine which system is “better.” Cooling technology, impedance monitoring, treatment tips, energy-delivery strategy, treatment areas, consumable costs, operator workflow and equipment investment all matter—especially for clinics and medical spas evaluating an RF platform.
This guide compares XERF vs Volnewmer from both a treatment and professional equipment perspective.
XERF vs Volnewmer: Quick Comparison
| Feature | FORKERT | Volnewmeter |
|---|---|---|
| RF type | Monopolær RF | Monopolær RF |
| RF -frekvens | 2 MHz + 6.78 MHz | 6,78 MHz |
| Technology Concept | Multifrequency RF with multiple depth settings | 6.78 MHz monopolar RF |
| Impedance Monitoring | Ja | Ja |
| Køleteknologi | Integrated cryogen delivery | Continuous contact/water cooling |
| Energikontrol | 3 depth settings and 10 intensity levels | Adjustable monopolar RF delivery |
| Treatment Tips | System-specific effectors | 4 tip sizes |
| Small-Area Tip | System dependent | I Tip: 0.25 cm² |
| Large-Area Tip | System dependent | S Tip: 16 cm² |
| Hovedapplikation | Controlled tissue coagulation / skin tightening | Controlled tissue coagulation / skin tightening |
| Numbing | Marketed as not requiring numbing | Designed for treatment comfort with cooling and vibration |
| FDA 510(k) | K251327 | K240248; additional clearance K253504 |
Both systems therefore belong to the monopolar RF category, but they should not be treated as technically identical platforms.
What Is XERF?
XERF is a monopolar RF platform developed by Lutronic and marketed by Cynosure Lutronic.
Its defining technical feature is its multifrequency RF architecture, combining 6,78 MHz og 2 MHz radiofrequency energy.
Rather than relying on only one RF frequency, the system is designed to provide different energy-delivery options according to the treatment strategy and tissue characteristics.
How Does XERF Work?
XERF applies monopolar RF energy through a treatment handpiece while a return path completes the electrical circuit.
Electrical resistance within tissue converts RF energy into heat, producing controlled thermal effects.
The system combines several technologies:
6.78 MHz + 2 MHz Multifrequency RF
XERF can operate at both 6,78 MHz og 2 MHz.
This is one of the most important technical differences between XERF and conventional single-frequency monopolar RF systems.
The system is designed around customizable RF delivery rather than simply applying one fixed frequency for every treatment.
It is important, however, not to interpret this as “two frequencies equals twice the power.” Frequency, output power, pulse characteristics, impedance, electrode design and treatment technique all affect how RF energy interacts with tissue.
Clinics interested in this technology can also explore our professional XERF alternative machine designed for aesthetic practices and med spas.
Multiple Depth Settings
XERF provides three depth settings together with 10 intensity levels, allowing the operator to adjust the treatment according to the patient’s skin characteristics and treatment objectives.
Cynosure Lutronic describes this approach as delivering energy across shallow, middle and deeper treatment levels.
Wave Fit™ Pulse Technology
XERF also incorporates Wave Fit™ pulse technology, which controls how RF energy is delivered during treatment.
Combined with its multifrequency architecture, this provides the operator with additional flexibility when selecting treatment settings.
Accurate Impedance Feedback
Skin and tissue electrical resistance varies among patients and treatment areas.
XERF uses real-time impedance feedback to help adapt energy delivery according to the electrical characteristics detected during treatment.
This is an important safety and consistency feature in professional monopolar RF systems.
XERF Cooling and Treatment Comfort
High-energy monopolar RF needs to generate sufficient thermal effects below the skin while limiting excessive heating at the epidermal surface.
XERF addresses this through Advanced Integrated Cryogen Delivery.
Cryogen cooling is delivered in coordination with RF pulses to help control surface temperature.
This cooling strategy is also central to XERF’s positioning as a treatment that can generally be performed without needles or topical numbing.
Patient comfort, however, is not determined by cooling technology alone. Energy level, treatment area, number of passes, operator technique and individual pain sensitivity can all influence treatment sensation.
Hvad er Volnewmer?
Volnewmer is a monopolar RF platform developed by Classys, the Korean aesthetic medical device company also known for systems such as Ultraformer.
Unlike XERF’s dual-frequency architecture, Volnewmer operates at:
6.78 MHz monopolar RF.
The RF current passes through tissue and is converted into thermal energy due to tissue resistance.
The system is designed to produce controlled tissue coagulation while its cooling technology helps protect the epidermal surface.
How Does Volnewmer Work?
Volnewmer’s treatment sequence integrates impedance measurement, cooling and RF energy delivery.
When the treatment tip contacts the skin, the system performs an automatic impedance check.
Cooling is then activated and RF energy is delivered into the target tissue.
CLASSYS describes the treatment energy as extending through the papillary and reticular dermis while continuous contact cooling protects the skin surface.
Volnewmer Continuous Cooling
One of Volnewmer’s key design characteristics is its continuous water/contact cooling system.
Rather than relying on cryogen delivery, the treatment tip maintains surface cooling before, during and around RF delivery.
The system also incorporates vibration intended to improve patient comfort.
This creates one of the clearest engineering differences between the two platforms:
XERF → Integrated cryogen cooling
Volnewmer → Continuous contact/water cooling
Neither cooling method should automatically be considered superior in every situation. Both are intended to balance effective thermal delivery with epidermal protection and treatment comfort.
Volnewmer Treatment Tips
Another notable characteristic of Volnewmer is its range of treatment tips.
The official system includes four tip sizes:
I Tip — 0.25 cm²
Designed for small and precise treatment areas.
F Tip — 3.0 cm²
Designed for facial treatment areas.
V Tip — 4.0 cm²
The main facial tightening and lifting tip.
S Tip — 16.0 cm²
A significantly larger treatment tip designed for larger areas such as the abdomen, arms and thighs.
This range allows operators to select different treatment areas without relying on one universal electrode size.
Volnewmer also incorporates a Hidden Edge electrode design intended to reduce excessive energy concentration around the perimeter of the treatment tip.
XERF vs Volnewmer: 7 Key Differences
Understanding the differences between XERF and Volnewmer requires looking beyond brand names.
Here are seven of the most important technical and practical distinctions.
1. RF Frequency
This is the clearest difference.
FORKERT
Uses:
2 MHz + 6.78 MHz monopolar RF
Volnewmeter
Uses:
6.78 MHz monopolar RF
XERF therefore offers a multifrequency architecture, while Volnewmer is built around a single 6.78 MHz RF frequency.
However, the number of frequencies should not be used as a standalone measure of treatment performance.
A two-frequency system is not automatically “twice as powerful” or clinically superior to a single-frequency system.
RF performance also depends on output parameters, pulse duration, electrode geometry, tissue impedance, cooling and treatment protocol.
2. Energy Delivery and Treatment Strategy
XERF emphasizes customizable, multi-depth RF delivery.
Its combination of two frequencies, three depth settings and multiple intensity levels gives practitioners several ways to configure treatment.
Volnewmer takes a different approach.
It uses established 6.78 MHz monopolar RF combined with automatic impedance detection, controlled energy delivery and multiple treatment tips.
Rent praktisk:
XERF emphasizes multifrequency and multi-depth energy customization.
Volnewmer emphasizes controlled 6.78 MHz RF delivery with multiple applicator sizes and continuous cooling.
These are different engineering strategies toward a similar overall goal.
3. Cooling System
Cooling is another major distinction.
XERF Cooling
XERF uses Advanced Integrated Cryogen Delivery.
Cryogen is coordinated with RF energy delivery to manage epidermal temperature.
Volnewmer Cooling
Volnewmer uses continuous water/contact cooling at the treatment tip.
Cooling can remain active even outside the RF energy pulse.
Both approaches are designed to protect the epidermis while allowing therapeutic heating below the surface.
Which feels more comfortable to an individual patient cannot be determined from the cooling technology alone.
4. Treatment Tips
Volnewmer has a particularly clear advantage in published tip-size variety.
Its four tips range from the very small 0.25 cm² I Tip til 16 cm² S Tip for larger treatment areas.
This can be useful for clinics that want one RF platform capable of treating both small facial areas and larger body areas.
XERF uses its own system-specific effectors and combines them with different depth and intensity settings.
For clinics comparing equipment, tip availability should be evaluated alongside another important factor:
consumable cost.
Treatment tips are not simply accessories. Depending on the platform, they can become a significant part of the cost per treatment.
5. Patient Comfort
Both systems place substantial emphasis on treatment comfort.
XERF combines RF energy control with cryogen cooling and is marketed around treatments that do not require routine numbing.
Volnewmer combines continuous cooling with vibration and controlled RF delivery.
Neither system can be declared universally “painless.”
Treatment sensation varies according to:
- RF energy level
- behandlingsområde
- number of passes
- skin characteristics
- treatment technique
- cooling settings
- individual pain tolerance
For clinics, comfort matters because it can influence treatment acceptance, repeat visits and overall patient experience.
6. Treatment Areas
Both platforms are primarily associated with non-invasive RF tissue coagulation and aesthetic skin-tightening applications.
Common treatment areas can include the face, jawline and other areas selected according to the device configuration and approved indications.
Volnewmer’s four-tip configuration provides a particularly straightforward approach to different treatment-area sizes.
Its 16 cm² S Tip, for example, is specifically presented by CLASSYS for larger areas including the abdomen, arms and thighs.
However, clinics should distinguish between technical capability og regulatory indication.
A handpiece being physically capable of treating an area does not necessarily mean that every indication is cleared or approved in every country.
Always check the manufacturer’s current labeling and local regulations.
7. Technology Positioning
The simplest way to understand the positioning difference is:
FORKERT
Multifrequency monopolar RF
Its primary differentiator is the combination of 2 MHz and 6.78 MHz with customizable depth and intensity settings.
Volnewmeter
6.78 MHz monopolar RF with multiple treatment tips
Its differentiators include continuous cooling, automatic impedance checking, multiple tip sizes and its Hidden Edge electrode design.
This does not make one technology universally better.
It means they approach monopolar RF treatment differently.

XERF vs Volnewmer Results
Both systems are designed to generate controlled RF-induced thermal effects within tissue.
These thermal effects are used in aesthetic practice to support tissue coagulation and subsequent remodeling processes associated with firmer-looking skin.
Common treatment objectives include:
- improving the appearance of skin laxity
- facial tightening
- improving jawline definition
- supporting collagen remodeling
- improving overall skin firmness
However, an important distinction needs to be made when comparing results.
There is not sufficient evidence to make a broad claim that:
“XERF produces better results than Volnewmer”
eller
“Volnewmer produces better results than XERF.”
Manufacturer before-and-after photographs and individual clinic experiences are not the same as controlled head-to-head clinical evidence.
Results can also depend heavily on patient selection, energy parameters, treatment technique and number of sessions.
For that reason, comparisons based purely on marketing before-and-after images should be interpreted cautiously.
XERF vs Volnewmer: Which Is More Comfortable?
There is no universal winner.
XERF approaches comfort primarily through integrated cryogen cooling combined with controlled RF pulse delivery.
Volnewmer uses continuous water/contact cooling combined with vibration.
Both technologies are specifically designed to reduce excessive surface heating and improve treatment tolerance.
For a clinic, the more useful question is therefore not simply:
“Which machine hurts less?”
It is:
“Which system can consistently deliver the required treatment parameters while maintaining acceptable comfort for our target patient population?”
That distinction matters.
XERF vs Volnewmer Cost
Cost should be considered from two different perspectives: the patient and the clinic purchasing the equipment.
Treatment Cost for Patients
The price of an XERF or Volnewmer treatment can vary significantly according to:
- country and city
- clinic positioning
- behandlingsområde
- behandlingsprotokol
- number of RF shots
- praktiserende læges erfaring
- antal sessioner
Therefore, there is no meaningful universal treatment price.
Patients should compare complete treatment plans rather than comparing one advertised session price in isolation.
XERF vs Volnewmer Machine Cost for Clinics
For a clinic or med spa, the purchase price of the machine is only one component of the investment.
A more useful calculation is:
Total equipment cost + consumables + maintenance + training + operating cost
compared with:
Treatment price × realistic treatment volume
When comparing professional monopolar RF machines, clinics should evaluate:
Initial Equipment Investment
What is the total delivered cost of the system?
Forbrugsomkostninger
How much does each treatment tip or disposable component cost?
How many treatments or shots can it provide?
Cost Per Treatment
A machine with a lower purchase price may not necessarily have the lowest operating cost.
Likewise, a premium machine may be financially viable if the clinic can maintain sufficient treatment volume and pricing.
Opretholdelse
Ask about:
- preventive maintenance
- handpiece replacement
- cooling-system maintenance
- technical support
- replacement parts
- repair turnaround time
Uddannelse
High-energy RF equipment requires proper operator training.
Training should cover not only how to operate the touchscreen but also patient selection, contraindications, parameter selection, endpoint assessment and adverse-event prevention.
Warranty and Technical Support
Equipment downtime directly affects clinic revenue.
Warranty coverage and after-sales response therefore deserve almost as much attention as the machine specification itself.
XERF vs Volnewmer for Clinics and Med Spas
For a professional buyer, the comparison looks different from a patient’s treatment comparison.
A clinic should evaluate at least five areas.
1. Treatment Versatility
Consider which areas and patient profiles you expect to treat most frequently.
A clinic focused almost entirely on facial rejuvenation may have different priorities from a medical spa wanting both facial and larger-area body RF treatments.
2. Consumables
Calculate the real consumable cost per treatment.
Do not compare only tip purchase prices.
Instead calculate:
Tip Price ÷ Usable Treatments = Consumable Cost Per Treatment
Then include any additional pads, cartridges or disposable accessories.
3. Treatment Throughput
Treatment room time can affect profitability.
Systems designed to operate without routine topical anesthesia may reduce preparation time, but actual throughput still depends on treatment area, protocol and clinic workflow.
4. Service and Training
For international buyers in particular, ask:
- Is remote technical support available?
- Are replacement parts stocked?
- How quickly can a failed handpiece be replaced?
- Is operator training included?
- Are treatment protocols provided?
5. Return on Investment
Instead of asking only:
“How much does the machine cost?”
ask:
“How many treatments do I realistically need to recover the investment?”
A simplified calculation is:
Break-Even Treatments = Total Initial Investment ÷ Gross Margin Per Treatment
A more realistic ROI model should also include marketing costs, staff time, consumables, maintenance and local overhead.

Is There a More Affordable Alternative to XERF and Volnewmer?
XERF and Volnewmer are established branded professional RF platforms, but they are not the only way for a clinic to introduce monopolar RF treatments.
For new medical spas, aesthetic clinics and equipment distributors, capital expenditure and ongoing consumable costs can be major considerations.
Mico Aes Professional Dual-Frequency RF System
For clinics and med spas looking for a more cost-conscious alternative, Mico Aes offers a professional RF system designed for non-invasive aesthetic treatments.
The system can be evaluated based on RF configuration, treatment tips, cooling technology, consumable costs, warranty and after-sales support.
Mico Aes systems are independently manufactured devices. They are not original Cynosure Lutronic XERF or CLASSYS Volnewmer systems.
When comparing an alternative RF machine, however, price should not be the only criterion.
Evaluate:
- RF frekvens
- actual RF output architecture
- impedance monitoring
- køleteknologi
- temperature and safety controls
- treatment tip sizes
- consumable life
- electrical safety documentation
- quality-management certification
- warranty
- operator training
- spare parts
- technical support
A low-cost machine without reliable energy control or technical support may ultimately be more expensive than a higher-quality system.

XERF vs Volnewmer: Which One Should You Choose?
There is no universal answer.
XERF may be worth considering if your priority is a premium branded system built around 2 MHz + 6.78 MHz multifrequency monopolar RF, customizable depth settings and integrated cryogen cooling.
Volnewmer may be worth considering if your priority is a branded 6.78 MHz monopolar RF platform with continuous contact cooling and multiple tip sizes covering small facial areas through larger treatment zones.
An alternative professional RF platform may be worth evaluating if your clinic places greater emphasis on initial equipment cost, consumable economics, customization, distributor pricing or return on investment.
The correct comparison is therefore not simply:
XERF vs Volnewmer—which machine is stronger?
A better question is:
Which RF platform provides the right combination of energy technology, treatment versatility, patient comfort, operating cost, support and ROI for your practice?
Ofte stillede spørgsmål

Sidste tanker
XERF and Volnewmer represent two different approaches to modern monopolar RF technology.
XERF differentiates itself through 2 MHz + 6.78 MHz multifrequency RF, multiple depth settings and cryogen-based cooling.
Volnewmer focuses on 6.78 MHz monopolar RF, continuous cooling, automatic impedance checking and a versatile four-tip treatment system.
For patients, the decision should be based on professional assessment and an appropriate treatment plan.
For clinics and medical spas, the comparison is broader. Equipment price, consumables, service, training, treatment throughput and ROI can be just as important as RF frequency.
And for buyers who find the investment in established branded platforms too high, professional alternative RF systems may also be worth evaluating—provided that specifications, regulatory status, manufacturer identity and compatibility are communicated transparently.
