If your jawline looks softer than it used to, non-surgical energy treatments may be worth discussing with a dermatologist. XERF and focused ultrasound therapy are two different approaches used to address skin laxity, including the appearance of jowls. They do not work in exactly the same way, and neither option is automatically right for every face.
For patients in South Florida, the practical choice often comes down to anatomy, the amount and location of laxity, treatment preferences, comfort considerations, and whether a non-surgical approach can realistically match the change you want.
Quick answer
- XERF uses radiofrequency energy to heat tissue beneath the skin and support collagen remodeling.
- Focused ultrasound uses ultrasound energy delivered to selected tissue depths to create controlled thermal effects that can stimulate collagen.
- Both approaches may help improve mild to moderate skin laxity without surgery, but the experience, energy delivery, and treatment planning differ.
- The appearance of jowls can involve skin, fat, facial structure, and deeper tissue changes, so an in-person evaluation is important before choosing a device.
- More pronounced laxity may require a different strategy if a non-surgical treatment is unlikely to provide the degree of change someone wants.
| Comparison | XERF | Focused ultrasound |
|---|---|---|
| Energy type | Radiofrequency | Focused ultrasound |
| General goal | Controlled tissue heating to support collagen remodeling and firmness | Focused thermal treatment at selected depths to support collagen remodeling and tightening |
| Jawline use | May be considered when skin firmness and lower-face laxity are concerns | May be considered for lax tissue along the lower face, under the chin, and neck |
| Planning | Settings and treatment areas are selected according to the patient’s anatomy and goals | Treatment depth and placement are selected according to anatomy and the device being used |
How XERF and ultrasound differ
The most important difference is the type of energy being delivered. XERF is a radiofrequency treatment. Radiofrequency devices create controlled heating beneath the skin, which may encourage collagen remodeling and improve the appearance of laxity over time.
Focused ultrasound devices use acoustic energy rather than radiofrequency. The energy can be concentrated at specific depths beneath the skin, creating small zones of controlled thermal treatment. That response may stimulate new collagen and contribute to gradual tightening.
Because the two technologies deliver energy differently, choosing between them is more nuanced than simply asking which one is stronger. A dermatologist may consider where the laxity is located, the thickness and quality of the tissue, facial proportions, prior procedures, and the type of change the patient is hoping to see.
What the treatments have in common
Both approaches are generally discussed as non-surgical options for people who want to address skin laxity without a facelift. They rely on controlled energy delivery rather than removing excess skin.
They also share an important limitation: a device cannot change every cause of a poorly defined jawline. What looks like jowling may reflect several factors at once, including reduced skin elasticity, changes in facial fat, loss of structural support, or more substantial tissue descent. Energy-based tightening may help one component without addressing all of them.
Practical clues that may influence the choice
A consultation should focus less on the device name and more on what is creating the change in your lower face. Helpful questions include:
- Is the main concern mild skin laxity, or is there substantial tissue descent?
- Is the softness concentrated along the jawline, under the chin, or through the neck as well?
- Have you previously had fillers, energy treatments, surgery, or other facial procedures?
- How much change are you expecting from a non-surgical treatment?
- Would another treatment category better address volume loss, skin quality, or facial structure?
These distinctions matter because two people who both describe their concern as “jowls” may need very different treatment plans.
What South Florida patients may want to consider
South Florida patients often include year-round residents, seasonal residents, and international visitors. If you divide your time between locations or travel frequently, discuss scheduling and follow-up before treatment so that your plan is realistic.
Daily sun protection also remains an important part of maintaining healthy-looking skin in a high-UV environment. Energy treatments do not replace a consistent skincare routine or sun-protective habits. Your clinician can explain any treatment-specific preparation or aftercare based on the device selected and your skin.
Limitations of non-surgical jowl treatments
Radiofrequency and focused ultrasound may be most useful when expectations match what a non-surgical treatment can reasonably accomplish. They are not substitutes for removing significant excess skin, and the degree of improvement can vary from person to person.
If laxity is pronounced, a dermatologist can help you understand whether an energy-based treatment is likely to provide a meaningful cosmetic improvement or whether discussing other options would make more sense. A thoughtful consultation should include what a treatment may improve as well as what it is unlikely to change.
What to do next
If you are comparing XERF with ultrasound therapy, an in-person assessment is the most useful next step. Your clinician can examine the lower face and neck, review your treatment history, clarify your priorities, and explain which approach may fit your anatomy and expectations.
At Waverly DermSpa, we offer XERF and can help you understand whether it may be appropriate.
FAQ
Is XERF the same as ultrasound skin tightening?
No. XERF uses radiofrequency energy, while focused ultrasound treatments use ultrasound energy. Both may be used to address skin laxity, but they deliver energy differently.
Can either treatment completely remove jowls?
Non-surgical tightening treatments may improve the appearance of mild to moderate laxity for appropriately selected patients, but they cannot remove excess skin in the way surgery can. The likely degree of improvement depends on individual anatomy and treatment selection.
Which treatment is better for the jawline?
There is no single answer for every patient. The better fit depends on what is causing the jawline change, tissue characteristics, previous treatments, personal preferences, and the amount of improvement being sought.
Can radiofrequency and ultrasound be combined with other cosmetic treatments?
Sometimes a broader plan may involve more than one treatment category because skin laxity, volume loss, texture, and facial structure are separate concerns. A dermatologist can determine whether combining or sequencing treatments is appropriate.
How quickly should I expect a change?
Collagen remodeling is gradual, so changes from energy-based tightening treatments can develop over time rather than appearing all at once. Timing varies by technology, treatment plan, and individual response. Your clinician can explain what is realistic for the specific device being considered.
