Why do XERF results vary by provider?
Written with
Marie Jin, ACNP-BC, board certified acute care nurse practitioner
From an interview: September 2026
XERF does not choose a treatment pattern on its own. Its three depth settings and ten intensity levels give the provider options, and the choice of areas, energy, and technique can change the outcome. Marie Jin describes her planning process as XERF mapping.
What does the device control?
XERF combines 6.78 MHz and 2 MHz radiofrequency with integrated cooling and impedance feedback. Those features support controlled energy delivery. They do not decide which parts of a face need the most attention. The provider still selects the setting and treatment pattern for each area.
What is XERF mapping?
In her September 2026 interview, Marie described drawing the plan on a face chart before treatment. She marks areas for lifting or collagen-focused work, considers how many shots each area gets, and adjusts the energy and technique. A cheek and a jowl may need different treatment choices even during the same session.
Skin thickness also changes what a provider can reasonably expect. Read how thin skin affects the plan and how the device works.
What should you ask a XERF provider?
Ask which areas they plan to treat, why they chose those settings, how they adjust treatment for different zones, and what changes if your skin is thin. The answers should be specific to your face. If you are also considering needles, compare XERF and Profound RF.
Common questions
Does XERF use the same setting everywhere?
It can be adjusted. Marie plans settings by area and treatment goal rather than assuming each zone needs the same delivery.
What information should I bring?
Bring your treatment history, goals, and any event dates that affect how you plan the series.
