One of the most common questions patients ask before getting XERF in Korea is:
“How many shots do I need?”
300 shots? 600 shots? 900 shots?
Shot count is useful when comparing treatment plans, but it does not tell the whole story.
With radiofrequency treatments such as XERF, the way the treatment is designed for your individual facial anatomy can be just as important as the number of shots delivered.
In other words, more shots do not automatically mean better results.
Why XERF Energy Settings Matter
Different parts of the face have different tissue thicknesses.
The cheeks, jawline, temples and areas around the eyes do not have the same amount of skin, fat or underlying structure.
This means that using exactly the same depth and energy everywhere may not be the most appropriate approach.
XERF treatment can be adjusted according to the area being treated, including how deeply the RF energy is delivered and how the energy is distributed.
The goal is not simply to use the highest possible setting.
It is to place the appropriate amount of energy in the appropriate tissue layer.
Can RF Treatments Cause Facial Fat Loss?
This is also why facial anatomy matters.
RF treatments work by delivering heat into tissue. When deeper treatment is performed too aggressively or in an area where preserving facial volume is important, unwanted fat loss can be a concern.
That does not mean that XERF automatically causes facial fat loss.
Rather, it means that the doctor needs to understand where deeper treatment is appropriate and where a more conservative approach may be preferable.
For patients who already have a slim face or limited facial fat, this can be particularly important when designing an RF treatment.
Deep Mode Is Not Simply “The Strongest Mode”
Patients sometimes assume that deeper or stronger treatment must create more lifting.
But RF treatment is not simply a matter of turning the energy up.
A deeper setting may be useful in certain areas, while another area may require a different approach.
The face needs to be assessed as a three-dimensional structure rather than treated as one flat surface.
This is why two patients receiving the same number of XERF shots may still receive very different treatment designs.
XERF Is About Customization
The most important question may therefore not be:
“How many shots am I getting?”
A better question is:
“How will those shots be used on my face?”
Treatment design can take into account facial structure, tissue depth, existing volume, skin laxity and the areas where lifting or tightening is actually needed.
This is also why treatment results cannot be judged by shot count alone.
A carefully designed 600-shot treatment and a poorly planned 900-shot treatment are not necessarily equivalent.
XERF is ultimately about customization — not simply maximizing shots or energy.
What Should You Ask Before Booking XERF?
Before choosing a clinic, it may be helpful to ask:
- Who determines the treatment depth and energy settings?
- Are different areas of the face treated differently?
- Does the doctor assess facial fat and tissue thickness before treatment?
- Is the treatment plan customized, or is the same protocol used for every patient?
These questions can tell you much more about the treatment than shot count alone.
Final Takeaway
When considering XERF in Korea, price and shot count are easy numbers to compare.
But they are only part of the treatment.
Energy placement, treatment depth and customization to your facial anatomy are what turn a machine-based procedure into an actual treatment design.
Watch the video above to hear the doctor explain why these details matter when performing XERF.
Individual treatment plans and results vary. An in-person medical consultation is recommended to determine the appropriate treatment approach for your facial anatomy and concerns.
