Non-Surgical Facial Lifting with Dual-Frequency Radiofrequency and Ultrasound-Guided Precision
The XERF Program is the world’s first multifrequency monopolar radiofrequency (RF) system for non-invasive skin tightening and rejuvenation that uniquely combines two RF frequencies (6.78 MHz & 2 MHz)—the latest technology approved by the US FDA. This allows energy to reach the retinacular cutis, the vertical retaining ligaments of the face.
XERF targets 3 different depth levels, from the superficial skin layers to the deeper facial structures and fat compartments, including the vertical ligaments. This effectively improves skin laxity, tightens facial contours, and smoothens the skin.
Why Dual Frequencies Matter
The dual-frequency capability of XERF sets it apart from traditional RF lifting devices.
- 6.78 MHz effectively tightens the dermis and superficial fat layers.
- 2 MHz penetrates deeper to target deeper structures.
This allows highly customized treatments tailored to the needs of each facial area.
Key Highlights of XERF
- Combines 6.78 MHz and 2 MHz RF, delivering heat energy across multiple tissue layers.
- Reaches three structural depths: upper, middle, and deep layers.
- Wave Fit Pulse Technology automatically adjusts energy output and temperature for comfort and safety, preventing heat build-up.
- ICD cooling system protects the epidermis, reduces discomfort, and eliminates the need for topical anesthesia.
- Specially designed treatment tips distribute energy evenly, minimizing side effects such as burning sensations or overheating.
Benefits of Treating Three Depth Levels
With dual-frequency RF, XERF accurately delivers energy to:
- Upper Dermal Layer
- Stimulates collagen and elastin production
- Improves firmness and elasticity
- Upper Fat Layer
- Tightens superficial fat compartments
- Enhances contour and structural support
- Lower Fat Layer
- Targets deeper fat and the retinacular cutis
- Improves deep structural tightening
Who Is XERF Suitable For?
- Those experiencing early facial sagging
RF energy reaches three layers—skin, fat, and retaining ligaments—to firm and lift the face. - Those with excess facial fat or double chin
XERF can reduce unwanted fat while lifting and contouring the facial structure. - Those with fine lines and skin texture concerns
Improves smoothness and reduces fine wrinkles on the face and around the eyes. - Those who fear pain or surgery
XERF uses ICD cooling, making the procedure comfortable without anesthesia and with no downtime.
Treatment Steps
- Consultation & Facial Assessment
The doctor evaluates facial anatomy and concerns to design a customized treatment plan, including energy levels and shot count. - Preparation
The skin is cleansed, and a grounding pad is placed on the back to ensure optimal RF delivery. - Treatment
Dr. Sroy’s ultrasound-guided technique is used to precisely assess facial layers and deliver energy to targeted depths. Patients feel gentle warmth alternating with cooling from the ICD system. - Completion
The skin is cleansed and moisturized. Patients can immediately resume normal activities.
How Long Do the Results Last?
Results generally last 8–12 months, varying by individual.
Annual maintenance 1–2 times per year is recommended for optimal lifting results.
Frequently Asked Questions
How long does the procedure take?
About 30 minutes or more, depending on the number of shots. No anesthesia is required.
Can I resume daily activities immediately?
Yes. There is no downtime. Mild pinkness may appear but resolves within a few hours.
Does it hurt? Do I need numbing cream?
No numbing is needed. The cooling system and automated energy control minimize discomfort.
Is there any special aftercare?
No special aftercare is required. You can wear makeup as usual.
How many sessions are required to see results?
Most people see results after 1 session, lasting 8–12 months. Annual treatments help maintain long-term tightening.
XERF Structural Lifting with Ultrasound Precision – Dr. Sroy’s Technique
Effective lifting results rely not only on the device but also on accurate diagnosis and personalized treatment planning.
At ATTA Clinic, Dr. Sroy performs facial ultrasound scanning before treatment to analyze the individual’s facial structure. This ensures energy is delivered precisely to the areas needing lifting or fat reduction, while protecting essential fat, such as baby fat, to avoid a hollow or aged appearance.
Dr. Sroy also places RF energy strategically along the retinacular cutis, the vertical ligaments responsible for facial support, achieving vertical lifting and structural tightening.
Comparing 4 Popular Lifting Technologies
XERF vs. Oligio
Both use monopolar RF, but:
- XERF: Dual frequencies (6.78 MHz + 2 MHz) deeper penetration
- Oligio: Single frequency (6.78 MHz) less depth
XERF vs. Thermage
Both are monopolar RF, but:
- XERF: Dual-frequency, greater structural reach
- Thermage: Single frequency (6.78 MHz), shallower compared to XERF
XERF vs. Ultherapy
- Ultherapy: Uses focused ultrasound (MFU-V) to precisely target the SMAS layer, like surgical facelift depth. Produces deep plane lifting with high precision imaging.
- XERF: Uses dual-frequency RF to tighten the retinacular cutis and contour the face with less discomfort due to cooling and automatic energy control.
The best choice depends on individual facial concerns and professional assessment.
Can XERF Be Combined with Other Treatments?
1.Injectables: Fillers & Botox
Can be combined in the same session depending on the doctor’s plan.
2.Ultherapy
Combining Ultherapy (deep SMAS lifting) with XERF (superficial & mid-layer tightening) provides comprehensive multi-layer lifting.
Typically, Ultherapy is done first, followed by XERF later for maintenance and enhanced tightening.
