XERF

How it works

XERF, from Cynosure Lutronic, is a monopolar radiofrequency platform that works at more than one frequency, 2 MHz and 6.78 MHz. Tissue responds differently to each frequency, which allows a practitioner to vary how the energy is distributed in the skin and underlying layers. As with other monopolar RF, heat is generated in the tissue as the current passes toward a return pad.

Good to know

• Multi-frequency designs give the practitioner additional options, but the plan still hinges on your skin and goals.
• A session is a series of passes with temperature checks, so timing varies with the treated area.
• Temporary flushing or warmth is the typical immediate response.
• People with pacemakers or similar implants should say so at the consultation.

What a XERF session means for your travel days

Set aside a block of time that includes cooling down, rather than assuming a quick drop-in. After leaving, you can stroll or shop, ideally in shade.

As results develop over weeks, the follow-up conversation can happen by message after you return home if the clinic offers that, though in-person checks remain preferable.
