Multifrequency monopolar radiofrequency that lifts and tightens at depth.
"Tightening only the surface produces a result that fades quickly. XERF delivers thermal energy deep into the dermis and the subcutaneous tissue, building firmness from the layers that aging hollowed out."
— Dr. Choi Dong-Il, Director
Multifrequency monopolar radiofrequency that lifts and tightens in a single treatment.
XERF combines two radiofrequency wavelengths — 6.78 MHz and 2 MHz — and delivers their energy in three controlled stages, reaching deeper layers of skin than conventional RF lifting devices.
The treatment refines the deep cheek, nasolabial fold, and jawline while restoring firmness in the underlying collagen, producing both lifting and tightening effects in the same session.
※ The result depends on the operator as much as the device. Anatomy-based precision is what makes the difference.
Suitable candidates, technique, and what to expect afterward.
Patients also concerned about texture, pore quality, or contour.
6.78 MHz + 2 MHz energy targeting the dermis and subcutaneous tissue together.
Adipocyte breakdown, fibrous-septal contraction, and collagen renewal.
XERF's integrated real-time cooling protects the skin and keeps the procedure comfortable.

XERF's ICD Cooling — an integrated real-time skin cooling system — regulates the surface temperature throughout the treatment, keeping discomfort to a minimum. Anesthesia is optional, the treatment is quick, and most patients return to daily activity right away — same-day makeup is generally fine, and no formal recovery period is needed.
Real-time skin temperature control significantly reduces discomfort, eliminating the need for anesthesia and shortening the procedure.
The treatment is planned around the underlying facial anatomy, building firmness without hollowing out the cheek.
Conventional 6.78 MHz RF reaches mostly the dermis. XERF adds 2 MHz to extend the target to the subcutaneous tissue, 5–10 mm beneath the surface.
Energy reaching the subcutaneous fat layer triggers adipocyte breakdown and septal contraction.
Thermal energy reaching the subcutaneous fat layer triggers adipocyte breakdown and contraction of the fibrous septae, producing both tightening and a visible lifting effect.
The treatment surface is 50% larger than conventional designs, so the same shot count delivers more total energy to the skin.
Cheek, forehead, and other large surfaces.
Spider-pattern contact face delivers up to 1.5× more energy than other RF systems for a comparable shot count.
Jawline, perioral, and other contoured regions.
Tear trough, paranasal, and other thin-skin zones.

Every treatment begins with a personal consultation with the surgeon.
Gangnam Seoyon uses only authentic medical-grade devices.
Depth, intensity, and pattern are tuned to each face individually.
Each patient is offered a private recovery room after treatment.
Videos on XERF are coming soon.
Every inquiry is reviewed personally by Director Choi Dong-Il.
