XERF
is a skin tightening device that uses Dual-Frequency Monopolar Radiofrequency (RF) technology (6.78 MHz + 2 MHz), developed by Cynosure Lutronic. It is approved by the US FDA, KFDA, and the Thai FDA.
The world’s first device with the ability to deliver thermal energy to three depth levels (upper dermis, mid dermis, and subcutaneous fat layer), stimulating collagen throughout all targeted layers in a single treatment. It is equipped with ICD Cooling and Wave Fit Pulse technology, which measures skin impedance in real time, allowing patients to feel only a gentle warmth without the need for topical anesthetic.
What is XERF?
XERF uses Dual-Frequency Monopolar RF (6.78 MHz + 2 MHz), the world’s first technology combining two RF frequencies to stimulate collagen and elastin across the skin, fat layer, and muscle layer in a single treatment.
- Utilizes Dual Frequency RF technology (2 MHz + 6.78 MHz) simultaneously
- Helps improve skin firmness and define facial contours naturally
- Non-surgical treatment with no downtime required
Treatment Areas
- Face
- Jawline
- Under the chin
- Neck
- All areas of the body
How Does XERF Work?
- Delivers RF energy to three different depth levels (superficial, middle, and deep), adjustable according to each treatment area.
- Wave Fit Pulse System: Measures skin impedance in real time and automatically adjusts the energy output.
- ICD (Integrated Cryogen Delivery) / Spider Web Pattern Cooling: Delivers cooling to protect the upper skin layer, reducing discomfort without the need for topical anesthetic.
- The thermal energy continuously stimulates neocollagenesis after treatment.
Benefits of XERF
- Dual-Frequency technology delivers deeper and broader RF energy than conventional RF treatments in a single session.
- Minimal discomfort without topical anesthetic due to the built-in cooling system.
- No downtime. Patients can immediately return to their normal daily activities.
- Most patients notice visible improvement after the first treatment, with collagen continuing to develop over the following months.
Who is Suitable for XERF?
- Individuals with mild to moderate skin laxity and loss of jawline definition.
- Those who are concerned about discomfort during aesthetic procedures.
- People with limited downtime who need to return to work or daily activities immediately.
- Individuals seeking comprehensive collagen stimulation and skin tightening without surgery.
Who is Not Suitable for XERF?
- Individuals with implanted electronic devices such as a pacemaker, or metal implants in the treatment area (e.g., gold threads).
- Individuals with active skin infections, open wounds, or skin diseases affecting the treatment area.
Before & After Treatment
Before Treatment
- Avoid irritating skincare products (AHA, BHA, retinoids) for 1–2 days before treatment.
- Avoid makeup and remove all metal accessories on the treatment day.
During Treatment
- Treatment takes approximately 30–60 minutes.
