What is Xerf?

Xerf is a monopolar radiofrequency device from Lutronic (now Cynosure Lutronic). It switches between two frequencies, 6.78 MHz for dermal tightening and 2 MHz for deeper heating near the fat layer, so the doctor can tighten hollow areas and contour the jawline in the same session.

It is one of the newer RF devices in Gangnam, and Apgujeong patients often compare it directly with Thermage.

How it works

The tip delivers RF pulses with bursts of cold gas cooling to protect the surface. The doctor uses the higher frequency on areas needing collagen tightening and the lower frequency along the jaw and under-chin.

Planning around your trip

Xerf questions

Why does Xerf use two frequencies?

6.78 MHz concentrates heat in the dermis for tightening, while 2 MHz spreads heat deeper toward fat for contouring.

Is Xerf better than Thermage?

They target similar problems. Xerf adds a deeper frequency for fat, while Thermage has a longer track record. The doctor's choice depends on your skin and fat distribution.

How long does a Xerf tip last?

Tips are rated by shot count, typically used for a 300 or 600 shot face treatment.

Is numbing cream needed?

Many clinics use it, though the cooling makes Xerf tolerable for some patients without it.

When will I see the full effect?

Most clinics say about 4 weeks for visible tightening, with continued change up to 3 months.

Can Xerf be used on the body?

Lutronic markets Xerf for face and body tightening. Ask whether the clinic has the body tip before booking.
