Omotesando Rejuva Medical Clinic’s Philosophy on XERF Personalized RF Treatment Designed for Facial Harmony — Not Just Skin Tightening
As we age, sagging around the jawline, cheeks, and lower face becomes more noticeable. Many people assume stronger treatment means better lifting, but in reality, every face is different: skin thickness, fat distribution, bone structure, and aging patterns vary significantly. What truly matters is "where, at what depth, and how much heat" is delivered.
At Omotesando Rejuva Medical Clinic, we see XERF not simply as an RF treatment, but as a tool to design and restore facial harmony.
XERF is the world’s first dual-frequency monopolar RF technology (6.78 MHz + 2 MHz), allowing energy delivery across multiple tissue depths to stimulate collagen remodeling and tissue tightening more precisely than traditional single-frequency RF devices.
Our Focus: Whole-Face Assessment
Rather than treating isolated areas, we carefully assess the following elements to design a customized irradiation pattern for each patient:
- Facial fat distribution and volume positioning
- Degree of sagging and jawline definition
- Lower face droopiness (around the mouth)
- Submental (double chin) fat volume
- Skin thickness variations across different areas
- Future structural aging changes
For instance, overly aggressive deep treatment in patients with low facial fat may create an hollow or aged appearance. On the other hand, patients with heavier, sagging tissue will benefit significantly from deeper structural tightening. The key is not maximum energy, but the right energy delivered to the right depth in the right patient.
Optimizing the Secondary Tightening Process
One of the most unique aspects of XERF is that improvement often continues over 1–3 months as collagen remodeling progresses after treatment. RF-induced tissue remodeling evolves gradually, meaning final results appear weeks or months later.
At Rejuva Medical Clinic, our protocols are designed to optimize this secondary contraction effect by adjusting the depth and energy delivery method to match each individual's skin condition. The ideal aesthetic result is looking naturally refreshed — as if you look healthier and better, but still like yourself.
Balanced Comfort and Safety
Many patients worry RF treatments will be painful. While XERF incorporates advanced cooling and real-time impedance feedback to improve comfort, physician technique and precise energy adjustment remain essential. Our goal is always to balance maximum effectiveness with clinical comfort.
Comparison of XERF and Other RF Devices
| Specification | XERF | Thermage FLX | Conventional RF |
|---|---|---|---|
| Frequency | 6.78MHz + 2.0MHz (Dual Frequency) | 6.78MHz (Single Frequency) | Single Frequency |
| Targeted Depths | Multi-layered (3 levels of depth adjustment) | Mid to Deep Dermis | Single depth |
| Pain Control | Highly reduced via integrated cooling & Wave Fit | Can cause significant heat pain | Varies, pain can be prominent |
| Key Advantage | Customized volume control tailored to facial fat | Uniform skin tightening | Basic heat stimulation |
Frequently Asked Questions (FAQ)
Q. When will I see the results of XERF?
A. You will feel an immediate tightening effect right after the procedure due to collagen contraction from the heat. The maximum lifting, structural definition, and skin elasticity will peak at 1–3 months after the treatment as new collagen remodeling progresses.
Q. Is the treatment painful? Do I need anesthesia?
A. XERF features real-time impedance feedback and a robust cooling system, which reduces discomfort significantly compared to older RF machines. Most patients complete the treatment without any numbing agent, but laughing gas or numbing cream is always available upon request.
Q. What is the difference between XERF and HIFU?
A. HIFU uses focused ultrasound to target the deepest SMAS muscle layer, acting as a deep structural lift. XERF (RF) delivers heat over a wider surface to tighten the dermis and subcutaneous fat layer, stimulating overall collagen production and fat tightening. Because they target different layers, combining both treatments provides the ultimate multi-layer lifting result.
