The questions people ask before spending $1,500, answered by the physician who performs the treatment. Including the ones most practices avoid.
XERF is a radiofrequency device that heats the deeper dermis and the fibrous layer beneath it to a temperature at which collagen contracts and new collagen is laid down over the following months. That mechanism is real and it is measurable. What it produces is a firmer, better-supported face — not a lift, and not a replacement for surgery.
If your skin is loose because the underlying structure has weakened, XERF addresses that. If your concern is volume loss, XERF will not fill it. If it is surface texture or pigment, XERF is the wrong device — a resurfacing laser is the right one. If the skin has descended far enough that it hangs, no energy device will lift it, and any practice telling you otherwise is selling you a disappointment.
The honest framing: XERF changes how well your face holds itself up. It does not change how much of it there is, and it does not change the surface. Practices that are vague about that distinction are the reason people leave energy treatments feeling they wasted their money.
This is the most searched question about the treatment and it deserves a direct answer: radiofrequency energy can affect subcutaneous fat, and facial fat loss is a recognised risk of RF treatment in general. It is not a myth invented on Reddit.
Fat is more thermally sensitive than dermis. If energy is delivered too deep, held too long, or stacked over an area that is already thin, the result can be volume loss in a face that needed the opposite. This is why the same device produces excellent results in one pair of hands and a hollow midface in another.
Depth control and assessment. The treatment is designed to deposit energy in the dermis and the fibrous septae, above the fat compartments. Whether it does depends on the settings chosen for your tissue, and on whether anyone looked at your tissue before choosing them.
A face with generous fat compartments tolerates aggressive settings. A thin face over forty, or one that has already lost midface volume, does not. That assessment is the difference, and it is the reason we perform it as its own appointment rather than as a formality before a treatment that was already booked.
Where we decline. If your midface is already hollow, XERF alone is likely to make it look more so — tightening the envelope over a volume deficit reveals the deficit. In those cases the plan starts with restoring structure and XERF comes later, or not at all. You will be told that at the assessment rather than after three sessions.
Every device in this category tightens skin. They differ in how deep the energy goes, how precisely the depth is controlled, and how much discomfort that costs you.
| Device | Energy | Reaches | Honest comparison |
|---|---|---|---|
| XERF | Radiofrequency | Deep dermis + fibrous layer | Depth is controlled rather than inferred. Comfortable enough not to need sedation. |
| Ultherapy | Ultrasound | SMAS, deepest of these | Reaches deeper than any RF device and has the longest track record. Notably more painful, and results are more operator-dependent. |
| Thermage | Monopolar RF | Dermis | The original. Single-treatment protocol, but less depth control and results are widely described as subtle. |
| Morpheus8 | RF microneedling | Dermis, via needles | Adds surface resurfacing that XERF does not. Involves needle penetration and real downtime. |
| Sofwave | Ultrasound | Mid-dermis | More comfortable than Ultherapy, shallower than both. Good for mild laxity. |
| CO2 laser | Ablative light | Surface | A different job entirely — texture and pigment, not laxity. Often sequenced with XERF rather than chosen instead of it. |
We do not offer every device on this list, and that is worth stating plainly: a practice that owns one machine will tell you that machine is the answer. What we can tell you is which concern each one addresses, and where XERF is genuinely the wrong choice.
You feel heat that builds through each pass and eases between them. Most people describe it as tolerable and warm rather than painful, and it is meaningfully more comfortable than Ultherapy. No numbing or sedation is used. If it becomes genuinely uncomfortable the settings are wrong and should be adjusted — tell whoever is treating you.
Radiofrequency has been used in aesthetic medicine for over two decades and no long-term systemic effects have been established. RF is non-ionising — it is not the kind of energy associated with cancer risk, which is a question people reasonably ask and rarely see answered. The recognised risks are local and near-term: prolonged redness, swelling, and in poorly delivered treatment, burns or the fat loss described above.
Some tightening is often noticeable within a few weeks, but that early change is tissue response rather than new collagen. The result you are paying for develops over three to six months. Most plans run to around three sessions spaced roughly a month apart, decided at your assessment rather than sold in advance.
Because the device is only part of the outcome. The variables are who assessed you, whether the settings suited your tissue, and whether the treatment was the right one for your concern in the first place. A patient treated for volume loss with a tightening device will write a poor review of a device that worked exactly as designed.
$1,500 per session. Most people are quoted a plan rather than a single session, and you receive a written quote for the whole plan before anything is scheduled.
Anyone with significant midface volume loss, anyone whose skin laxity has progressed past what energy can address, and anyone whose actual concern is surface texture or pigment. Pregnancy and certain implanted electronic devices are contraindications. These are assessment findings, not form questions.
The assessment decides that. Sometimes the answer is no.
