XERF
Non-Surgical Skin Tightening in Bangkok
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.
- Advanced technologyUtilizes Dual Frequency RF technology (2 MHz + 6.78 MHz) simultaneously
- Natural-looking resultsHelps improve skin firmness and define facial contours naturally
- No incisions, no downtimeNon-surgical treatment with no downtime required
Treatment Areas
- Face
- Jawline
- Under the chin
- Neck
- All areas of the body
How Does XERF Work?
- 01Three depth levelsDelivers RF energy to three different depth levels (superficial, middle, and deep), adjustable according to each treatment area.
- 02Wave Fit Pulse SystemMeasures skin impedance in real time and automatically adjusts the energy output.
- 03ICD (Integrated Cryogen Delivery) / Spider Web Pattern CoolingDelivers cooling to protect the upper skin layer, reducing discomfort without the need for topical anesthetic.
- 04Ongoing collagen stimulationThe thermal energy continuously stimulates neocollagenesis after treatment.
Benefits of XERF
