Experience it at last — Monopolar RF that delivers thermal energy deep into the skin
"For skin emptying due to aging, just pulling the surface will never last long. XERF fills energy deep into the dermis, creating elasticity that rises from within."
— Dr. Choi Dong-il, Chief Director
Tightening and lifting at once — A new concept Monopolar RF lifting procedure.
Unprecedented in existing RF lifting devices, 2MHzis added, 6.78MHz and 2MHz The two frequencies are combined to divide the energy into 3 steps, delivering deeper energy into the skin.
Improves jowls, nasolabial folds, and jawline, makes the collagen membrane elastic, making it a lifting procedure where you can experience both lifting and tightening effects simultaneously.
※ XERF lifting is created by a 'person', not a machine. Precise procedures based on facial anatomy determine the results.

ICD Cooling System, a real-time temperature control system that protects the skin. Pain is significantly reduced, and quick procedures are possible without anesthesia. Immediate return to daily life is possible, and same-day makeup is OK! No separate recovery period is required.
Protects the skin with a real-time temperature control system. Pain is significantly reduced, and quick procedures are possible without the need for anesthesia.
Gangnam Seoyeon provides firm elasticity without cheek hollowing through precision procedures based on facial anatomy.
While conventional RF targets only the shallow dermis at 6.78MHz, XERF adds 2MHz to target the subcutaneous fat layer at a depth of 5~10mm.
Heat delivered to the subcutaneous fat layer induces fat cell breakdown + fibrous septum contraction
The heat delivered to the subcutaneous fat layer induces fat cell breakdown and contraction of the fibrous septum, tighteningas well as lifting effects.
With a tip 50% wider than conventional procedures, more energy is delivered even with the same 300 or 600 shots.

Covers wide areas such as the cheeks and forehead.

Wider contact surface with a spider pattern. Delivers 1.5 times more energy than other RF lasers.

Precision procedure for curved areas such as the chin and around the mouth.

Precision application for thin areas such as under the eyes and sides of the nose.
