XERF

How it works

XERF is a monopolar radiofrequency device from Cynosure Lutronic. It can deliver energy at two frequencies, 2 MHz and 6.78 MHz. Lower frequencies are generally associated with deeper heating, and higher ones with more surface-level effects. By combining them, a provider can shape the heat pattern in one visit. The goal is tightening and collagen remodeling over time, and results vary.

Good to know

• Multi-frequency means more than one energy setting is available. It does not mean more is used on every patient.
• Ask which frequency is planned for which area.
• Heat feelings change with frequency and tip.
• Redness, swelling, and rarely burns are possible.

Asking about XERF in English

Ask the coordinator to confirm the full maker name, Cynosure Lutronic, and the device name XERF. If the staff only say "RF lifting," politely ask for the product name.

You can ask the doctor, "Which frequency will you use first, and why?" Also ask what changes if you find the heat too strong. Request that your energy settings and number of passes be written in your aftercare sheet.
