Thermage and Ultherapy are both non-surgical skin-tightening technologies, but they use different forms of energy and affect tissue differently. Thermage FLX uses monopolar radiofrequency to heat broader areas of deeper skin and underlying tissue. Ultherapy uses microfocused ultrasound with visualization to place small points of thermal energy at selected depths. Neither is a substitute for surgery, and neither is automatically the better choice.
The clinic’s Thermage FLX and Ultherapy pages describe the technologies separately. The more useful comparison begins with the location and degree of laxity, skin thickness, underlying structure, and the kind of change a patient is hoping to see.
How Thermage FLX Works
Thermage FLX uses monopolar radiofrequency energy. A treatment tip passes over the skin while radiofrequency creates heat within deeper tissue. Surface cooling is used at the same time to help protect the epidermis and improve comfort.
The controlled heat is intended to cause some immediate collagen contraction and then stimulate remodelling over the following months. Because the energy is delivered across a treatment zone rather than into isolated ultrasound points, Thermage is generally discussed as a broader firming treatment.
At Anti-Aging Vancouver, Thermage may be considered for mild laxity on areas such as the face, jawline, around the eyes, neck, abdomen, or thighs. The goal is gradual firming rather than dramatic repositioning of tissue.
How Ultherapy Works
Ultherapy uses microfocused ultrasound with visualization, often shortened to MFU-V. Ultrasound imaging allows the provider to see tissue layers while treatment energy is delivered as small thermal coagulation points at predetermined depths.
This makes the technology different from surface resurfacing. The skin remains intact, while focused ultrasound is directed into deeper tissue layers involved in support and tightening.
A 2025 systematic review and meta-analysis of 42 studies found improvement in global aesthetic assessments after MFU-V, while also noting variation among studies and the need for stronger trials. Temporary redness, swelling, bruising and tenderness were among the commonly reported effects.
Thermage vs Ultherapy at a Glance
| Question | Thermage FLX | Ultherapy |
|---|---|---|
| Energy | Monopolar radiofrequency | Microfocused ultrasound |
| Delivery | Broader volumetric heating | Discrete thermal points at set depths |
| Typical emphasis | General firming and mild laxity | Lifting-type goals in selected facial and neck areas |
| Surface injury | No intentional resurfacing | No intentional resurfacing |
| Recovery | Usually limited | Usually limited |
| Result timing | Gradual | Gradual |
These differences can guide a conversation, but they do not determine candidacy.
Does One Tighten More Than the Other?
Current evidence does not support a simple universal winner.
A small randomized split-face trial compared monopolar radiofrequency with microfocused ultrasound with visualization in 20 people with mild to moderate facial and upper-neck laxity. Both sides improved through six months, and the study found no statistically significant difference between the two treatments on its laxity grading scale.
That study is useful because it directly compared the modalities, but it was small. It does not prove that both devices will perform identically for every person, treatment area, or degree of laxity.
A broader systematic review of radiofrequency devices also found evidence of measurable improvement in facial and body skin laxity with monopolar and bipolar radiofrequency. As with ultrasound studies, device settings, patient selection, and outcome measures vary.
Which Areas May Favour One Approach?
Treatment planning depends partly on anatomy.
The clinic’s Non-Surgical Skin Tightening guide describes Thermage as an option for more general firming across the face, jawline, neck, and selected body areas. Ultherapy may be considered when the goal is a lifting-type change around the brow, jawline, or neck and the clinician wants to target deeper foundational tissue.
That does not mean Thermage is only superficial or Ultherapy is always stronger. They distribute energy differently. The practical question is which pattern of energy delivery better matches the tissue being treated.
Comfort and Recovery Are Different Considerations
Both treatments work through intact skin, so neither involves surgical incisions or intentional peeling. Temporary redness, warmth, swelling, tenderness, or sensitivity can occur.
Ultherapy can feel intense because focused energy is deposited at multiple points beneath the skin. A 2025 meta-analysis reported moderate average pain across the studies it reviewed, although treatment experience varied considerably.
Thermage delivers repeated pulses of heat with surface cooling. Sensitivity depends on the area, settings, and individual response.
“Little downtime” should not be interpreted as “nothing happens afterward.” A provider should explain what is typical for the exact area and device being considered.
What Neither Treatment Can Do
Thermage and Ultherapy are intended for non-surgical tightening. They cannot remove excess skin or reposition substantially descended facial tissue the way surgery can.
This distinction becomes especially important with established jowls or significant neck laxity. The clinic’s skin-tightening information describes the expected change from energy-based treatment as modest and gradual. When laxity is substantial, a surgical opinion may be more appropriate than escalating energy treatment.
They also do not replace lost facial volume. If a softer jawline is caused partly by volume loss, fat distribution, muscle, or skeletal structure, tightening alone may not address the whole concern.
What a Consultation Should Compare
An assessment may consider:
where the laxity sits and how pronounced it is
skin thickness and quality
the face, neck, eye area, or body region being treated
underlying volume loss or structural changes
previous procedures
implants or medical devices
tolerance for treatment discomfort
realistic expectations for gradual improvement
The point is to select the technology after understanding the concern, not to fit the concern to whichever device is more familiar.
Frequently Asked Questions
Is Ultherapy a laser?
No. Ultherapy uses focused ultrasound energy. Thermage uses radiofrequency. Neither is a laser.
Does Thermage melt facial fat?
Thermage is used for skin tightening, not as a facial fat-reduction treatment. Energy placement and anatomy still matter, which is why treatment should be planned by a qualified provider.
Which has less downtime?
Both are generally associated with limited interruption to normal activities, but temporary redness, swelling, tenderness, or sensitivity can occur. Individual recovery varies.
Can Thermage and Ultherapy be combined?
They may be considered within a broader plan, but combining devices should have a clear reason. More energy-based treatment does not automatically produce a better result.
Match the Energy to the Tissue
Thermage and Ultherapy share a broad goal of non-surgical tightening, but they reach tissue differently. Thermage uses monopolar radiofrequency for broader heating and gradual firming. Ultherapy uses visualized microfocused ultrasound to create thermal points at selected depths.
The right comparison is therefore about anatomy, degree of laxity, treatment area, comfort, and realistic expectations.
