1. XERF vs Thermage vs Ultherapy: Which Skin Tightening Treatment Is Right for You?
Understanding three leading non-surgical lifting technologies
When patients search for skin tightening in Sydney or a non-surgical face lift, the most common options are often XERF, Thermage FLX, and Ultherapy. All three treatments are designed to support collagen remodelling and improve the look of skin firmness, but they work in different ways.
XERF is a newer dual-frequency monopolar RF skin tightening system, using both 6.78 MHz and 2 MHz radiofrequency energy with integrated cooling technology. Thermage FLX is an established monopolar radiofrequency treatment designed to smooth, tighten, and contour the skin without surgery or injections. Ultherapy uses microfocused ultrasound energy and is FDA-cleared for lifting the brow, neck, under-chin area, and improving lines on the décolletage.
At Medical Aesthetics 360°, the best option is selected based on your skin thickness, degree of laxity, treatment area, pain tolerance, and whether your main goal is skin firming, jawline definition, lower-face tightening, or a more lifted look.
2. How They Work: RF Skin Tightening vs Ultrasound Lifting
XERF and Thermage use radiofrequency; Ultherapy uses focused ultrasound
The key difference between XERF, Thermage, and Ultherapy is the type of energy used. XERF and Thermage are both forms of RF skin tightening, meaning they deliver radiofrequency heat into collagen-rich layers to encourage visible tightening and collagen remodelling. Thermage FLX delivers controlled radiofrequency energy into deeper collagen-rich tissue without disrupting the skin surface.
XERF is different from traditional single-frequency RF because it uses dual-frequency monopolar RF, combining 6.78 MHz and 2 MHz to deliver energy at different tissue levels, with advanced cooling designed to maintain surface comfort. This makes it attractive for patients wanting RF skin tightening with strong energy delivery and improved comfort.
Ultherapy, by contrast, uses microfocused ultrasound. It is often chosen when the treatment goal is more specifically related to non-surgical lifting, such as the brow, under-chin area, jawline, and neck. A systematic review described microfocused ultrasound as an energy modality used for skin rejuvenation and collagen-related wound-healing response.
3. Best Areas to Treat: Face, Jawline, Neck, Eyes and Lower Face
Choosing the right device depends on the area and type of ageing
For loose skin, fine lines, and overall skin firmness, Thermage FLX is often considered a strong option because it can smooth, tighten, and contour without surgery or needles. It is commonly discussed for the face, eye area, neck, abdomen, thighs, and body skin tightening, depending on assessment and suitability.
For patients who want structural skin tightening with RF, especially around the lower face, cheeks, jawline, and neck, XERF may be suitable because its dual-frequency monopolar RF system is designed to deliver heat to deeper and structural layers while using integrated cooling for comfort.
For patients whose main concern is a visible lift, especially the brow, under-chin, neck, and décolletage, Ultherapymay be preferred because it uses ultrasound energy and has specific FDA-cleared lifting indications for these areas.
In simple terms:
XERF may suit patients wanting newer-generation RF tightening with comfort-focused delivery.
Thermage may suit patients wanting a classic, established RF skin tightening treatment.
Ultherapy may suit patients wanting a more ultrasound-based non-surgical lifting approach.
4. Results, Downtime and Comfort: What Patients Should Know
Skin tightening is gradual because collagen takes time to remodel
With XERF, Thermage, and Ultherapy, results are not the same as a surgical facelift. These are non-surgical skin tightening treatments designed for gradual, natural-looking improvement in firmness, contour, and collagen support.
Thermage describes its treatment as having little to no downtime, with results that may appear immediately and continue to improve over time. Ultherapy also works through collagen stimulation and is used for gradual lifting and tightening, although common side effects can include redness, swelling, pain, and temporary nerve-related effects.
Comfort can vary between patients. Some people find ultrasound-based treatments sharper or more intense in bony areas such as the jawline or brow. RF treatments can feel hot or deeply warm. XERF’s integrated cooling and pulse technology are designed to control energy delivery while maintaining surface temperature, which may improve treatment comfort for suitable patients.
Because everyone’s skin thickness, collagen quality, facial structure, and pain tolerance are different, a consultation is important before choosing between XERF vs Thermage vs Ultherapy.
5. XERF vs Thermage vs Ultherapy: Which One Should You Choose?
The best non-surgical lifting plan is personalised, not one-size-fits-all
There is no single “best” skin tightening device for every patient. The right choice depends on whether your priority is firmness, lifting, contouring, skin quality, jawline definition, or neck tightening.
Choose XERF if you are interested in a newer dual-frequency RF skin tightening option with comfort-focused energy delivery. Choose Thermage FLX if you want a well-established radiofrequency skin tightening treatment for smoother, firmer-looking skin. Choose Ultherapy if your main concern is non-surgical lifting, especially around the brow, under chin, jawline, and neck.
For many patients, the best result may come from a skin tightening treatment plan rather than choosing only one device. For example, some patients may benefit from RF-based tightening for skin quality and firmness, while others may benefit from ultrasound lifting for deeper structural support. In some cases, skin tightening may also be combined with laser, collagen-stimulating treatments, or volume restoration depending on the cause of facial ageing.
