XERF Dual-Frequency Monopolar RF System

6.78 MHz and 2 MHz monopolar RF for professional use

XERF is a non-invasive monopolar RF system with three thermal diffusion modes for different treatment areas and tissue thicknesses. It combines Wave Fit multi-pulse delivery, impedance synchronization, surface-temperature monitoring, and adjustable ICD cooling.

The standard package includes four Effector sizes, with 40 Effectors in total, plus patient return pads, video training, and operating documentation.

How it works

Monopolar RF delivers electrical energy from a treatment electrode through the tissue to a patient return electrode. Tissue resistance converts this energy into heat, which can produce collagen contraction and support subsequent tissue remodelling.

Skin thickness, tissue composition, and contours vary across the face and neck. XERF uses two frequencies and three selectable modes to adjust thermal diffusion to the treatment area.

For a broader look at RF technology, read our monopolar RF vs bipolar RF comparison.

Mode	RF frequency	Relative thermal diffusion	Treatment considerations
Shallow	6.78 MHz	Lowest of the three modes	Thin, narrow, or delicate areas
Middle	6.78 MHz	Moderate	General facial and neck treatment
Deep	6.78 MHz followed by 2 MHz	Deepest of the three modes	Lower face, jawline, submental area, and thicker tissue

Practitioners select the mode according to the patient’s anatomy, skin condition, medical history, and treatment goals.

Four disposable Effectors

Effector	Contact dimensions	Maximum RF energy	Shot count	Typical application
Effector 05	5 × 10 mm	18.7 J	600	Small, narrow treatment areas
Effector 10	10 × 10 mm	38.1 J	600	Small or curved facial areas
Effector 40	20 × 20 mm	140 J	600	General facial and neck coverage
Effector 60	20 × 30 mm	220 J	600	Larger areas or thicker tissue

The Effectors use a spider-pattern electrode designed to distribute energy across the contact surface and reduce concentration at the edges. Proper skin contact must be maintained during RF delivery.

Effector selection depends on the area’s size, contours, and tissue thickness. Shot count alone does not indicate treatment energy; contact size, pulse energy, accumulated energy, and treatment mode also matter.

Treatment areas and objectives

Potential treatment areas include the forehead, periorbital and perioral regions, cheeks, lower face, jawline, jowls, submental area, and neck. Treatment must follow the device’s authorized indications and local requirements.

Treatment objectives may include improving the appearance of mild to moderate skin laxity, fine lines, reduced elasticity, and loss of facial definition.

Some patients may notice early firmness, with further changes developing over the following weeks and months. Results vary with skin condition, treatment settings, operator technique, and the treatment plan. XERF is not a substitute for surgery and does not produce surgical facelift results.

Research background

Histological research cited by Lutronic reports collagen changes in the dermis and deeper subcutaneous tissue, including changes toward the deep fascial or SMAS region, following combined 6.78 MHz and 2 MHz RF application. These observations do not guarantee a specific treatment depth or clinical result for every patient.

Why Dual-Frequency RF?

Traditional monopolar RF platforms commonly operate at a single frequency, creating a relatively fixed thermal profile.

However, facial and body anatomy is not uniform. The forehead, cheeks, jawline, neck, abdomen, and thighs differ in:

• Skin thickness
• Connective tissue density
• Subcutaneous fat distribution
• Surface contours
• Electrical impedance
• Required treatment depth

Different treatment areas vary in tissue thickness and contours. Combining 6.78 MHz and 2 MHz gives practitioners more options for adjusting energy delivery to these differences.

Shallow and Middle modes use 6.78 MHz with different settings. Deep mode delivers 6.78 MHz followed by 2 MHz in sequence. The resulting heating pattern depends on pulse timing, energy output, Effector design, cooling, and tissue characteristics—not frequency alone.

For a closer look at the technology, read how 6.78 MHz and 2 MHz dual-frequency monopolar RF works.

Treatment process

1. Consultation: Assess skin condition, tissue thickness, medical history, previous procedures, contraindications, and treatment goals.
2. Preparation: Clean the area, position the patient return pad, and apply the required coupling medium according to the operator’s manual.
3. Parameter selection: Choose the Effector, treatment mode, output level, cooling level, shot interval, and activation method.
4. Impedance synchronization: Establish proper contact and complete synchronization before delivering RF energy.
5. Treatment: Maintain full Effector contact while monitoring skin response, patient comfort, temperature, and delivered energy.
6. Post-treatment assessment: Remove the coupling medium, assess the skin, and provide aftercare instructions.

A typical facial treatment may take approximately 15–30 minutes. Duration varies with the treatment area, Effector, settings, and number of shots.

Many treatments can be performed without anesthesia, although comfort management should be determined by the practitioner. Temporary redness, warmth, swelling, or sensitivity may occur. Patients can generally resume daily activities shortly afterward, subject to their skin response and aftercare instructions.

The number of sessions should be determined during consultation.

Frequently Asked Questions

What is XERF?

XERF is a non-invasive monopolar RF system that combines 6.78 MHz and 2 MHz frequencies to create Shallow, Middle and Deep thermal diffusion modes.

How is XERF different from conventional monopolar RF?

Conventional platforms commonly use one RF frequency. XERF uses 6.78 MHz and 2 MHz, allowing the practitioner to select different thermal diffusion depths according to the treatment area and tissue characteristics.

How does Deep mode work?

Deep mode delivers 6.78 MHz and 2 MHz sequentially, creating the deepest thermal diffusion of the three available modes.

Does XERF reach the SMAS?

Official histological research cited by Lutronic reported collagen changes extending toward the deep fascial or SMAS region after combined 6.78 MHz and 2 MHz RF application. Actual energy distribution depends on the selected parameters and individual tissue characteristics.

Is XERF painful?

Patients generally experience warmth during treatment. Wave Fit Pulse and ICD cooling are designed to reduce discomfort and control surface heating. Individual sensitivity varies.

Is anesthesia required?

Many treatments can be performed without anesthesia. The practitioner should determine the appropriate comfort-management approach for each patient.

How long does treatment take?

A typical treatment takes approximately 15–30 minutes. Treatment time varies according to the area and number of shots.

Is there any downtime?

XERF is non-invasive and generally requires minimal or no significant downtime. Temporary redness, warmth, swelling or sensitivity may occur.

When can results be seen?

Some patients may notice early firmness following treatment. Progressive improvement may develop over the following weeks and months as collagen remodelling continues.

How many treatments are required?

The appropriate number of treatments depends on skin condition, degree of laxity, treatment area and clinical objectives. A qualified practitioner should recommend an individualized treatment plan.

Which Effector should be used?

Effector selection depends on the size, contour, and thickness of the treatment area. XERF provides 5 × 10 mm, 10 × 10 mm, 20 × 20 mm and 20 × 30 mm options.

Are 600 shots always equivalent between different RF systems?

No. Shot count alone does not determine total treatment energy. Effector size, pulse energy, depth, output level and accumulated delivered energy should also be considered.

Can patients return to daily activities after treatment?

Most patients can return to normal activities shortly after treatment, subject to their individual skin response and practitioner’s instructions.

Is XERF safe?

XERF incorporates impedance synchronization, surface-temperature monitoring, adjustable RF levels, three-level ICD cooling, and system alerts to support controlled treatment. The system must be operated by appropriately trained professionals according to the operator’s manual.

Important Safety Information

XERF must be operated by trained professionals after reviewing the patient’s medical history and suitability for treatment.

The system must not be used on patients with:

• A cardiac pacemaker
• An automatic implantable cardioverter-defibrillator
• Other implanted electrical devices

Additional contraindications, warnings and precautions in the official operator’s manual must be reviewed before treatment.
