Radiofrequency (RF) and microwave technologies work by delivering controlled electromagnetic energy into tissue to produce thermal effects — collagen denaturation and subsequent remodeling, fibroblast activation, and in select frequencies, selective fat-membrane disruption. Unlike HIFU (high-intensity focused ultrasound), RF devices heat tissue through resistive or capacitive current rather than acoustic focusing, allowing wider area coverage with calibrated depth control by adjusting frequency and electrode geometry.
Kind Global Clinic Myeongdong maintains four body RF platform options, each occupying a distinct position in the technology stack:
1. Onda Coolwaves (DEKA, Italy) — 2.45GHz microwave energy delivered via a handpiece with integrated contact cooling. Microwave at this frequency selectively targets water content in fat-cell membranes, causing selective adipocyte disruption with simultaneous skin-surface cooling to protect the epidermis. Primary indication: subcutaneous fat reduction and cellulite on abdomen, thigh, flank and inner arm. KFDA and CE-marked for body fat and cellulite.
2. Density (Jeisys Medical, Korea) — 6.78MHz sequential monopolar-then-bipolar RF in a single handpiece. The mono sub-pulse heats deep dermis first, the bi sub-pulse follows at shallow depth (400W, 6.78MHz). Layered thermal effect across dermis depth for skin tightening on face and body in patients with sensitive or rosacea-prone skin. Primary body indication: arm, inner thigh, and periumbilical skin laxity in patients who found Thermage heat uncomfortable.
3. Thermage FLX (Solta Medical, USA) — monopolar RF at 6.78MHz with capacitive energy transfer and vibration comfort system. The standard global platform for monopolar RF skin tightening with a body tip offering 900 shots per disposable tip. Primary body indication: surface skin toning, abdominal skin tightening, arm and thigh surface laxity.
4. Oligio X (Wontech, Korea) — dual-mode 6.78MHz RF with collagen-stimulation protocol for series treatment. Primary body indication: periumbilical skin quality series, arm inner surface laxity, accessory body zones.
All four devices are operated personally by the co-directors — there is no nurse delegation on any body RF procedure. Device tip serials and shot counts are recorded on each patient's chart.
