Key summary Ultherapy is a non-surgical lifting procedure that uses focused ultrasound heat energy at a specific depth beneath the skin to lift sagging areas. People typically consider it when they want to address mild facial and neck sagging without incisions. Research showed changes appearing 1-3 months after the procedure continuing until approximately 6 months, and while it could feel more painful than Thermage, there was no clear difference in the degree of sagging improvement.
01 At what layer of skin does Ultherapy work?
Ultherapy uses ultrasound imaging to visualize skin layers and focuses energy at a desired depth. Similar to how a magnifying glass concentrates sunlight to a single point, it passes through the skin surface and creates a small heat spot only beneath, causing the heated tissue to contract. During the recovery process, collagen production continues, and sagging areas gradually lift.
The device is registered with the U.S. FDA under the category of "Focused ultrasound for tissue heating" (product code OHV). In Korea, it is confirmed in the MFDS medical device UDI database as "Approval 09-1024" (Class III Focused Ultrasound Stimulation System).
02 When do results appear and how long do they last?
Research showed facial and neck changes beginning to appear 30-90 days after the procedure and remaining through 180 days. Both trials directly comparing Ultherapy and radiofrequency had 20 participants each, so while the direction of results can be seen, these are not large studies sufficient to apply directly to all ages and skin conditions.
| Item | Confirmed Information |
|---|---|
| Time of improvement | Face, upper neck: Significant from 30 days / Neck: Significant from 90 days |
| Neck sagging grade progression (focused ultrasound group) | Pre-procedure 2.8 → Day 30 2.4 → Day 90 1.5 → Day 180 1.4 (lower grade indicates less sagging) |
| Neck sagging grade progression (radiofrequency group) | Pre-procedure 2.7 → Day 30 2.1 → Day 90 1.6 → Day 180 0.86 |
| Global Aesthetic Improvement Scale (GAIS) | Both methods reported improvement on days 30, 90, 180 |
| Duration | Maintained through 180 days of follow-up (beyond that is outside research scope) |
| Subjects | Mild to moderate sagging, each study approximately 20 participants |
| Pain | Greater pain during treatment compared to radiofrequency (Thermage class) |
| Side effects | Mild, temporary |
| Academic assessment (based on separate meta-analysis) | Promising but controversial, high-quality standardized research needed |
The key point of the table is results do not complete immediately after the procedure but appear over 1-3 months, and were maintained through the 6-month endpoint when the research ended. Neck sagging scores improved with both methods, but there was no clear difference showing one was better than the other. The clearly distinguishing factor was that Ultherapy caused more pain. Both trials were confirmed only through abstracts with 20 participants each, making it difficult to assess maintenance duration beyond 6 months or the magnitude of individual variation from this data.
03 What should I verify before treatment?
| Verification Item | Why Check | Verification Method |
|---|---|---|
| Device approval | Authentic, properly approved device | MFDS Medical Device UDI/EDI database check; Ultherapy devices are listed as "Approval 09-1024" |
| Provider qualifications | Specialist status, experience | Hospital information + Health Insurance Review and Assessment Service public data (number of specialists per institution) |
| Effectiveness and duration explanation | To detect exaggeration | Research tracked only through 180 days, and in a study of 20-person scale; language like "permanent" or "guaranteed" is a warning sign outside this scope |
| Pain management | Pain is generally higher than radiofrequency | Whether anesthesia and pain management methods are explained beforehand |
| Side effect information | Swelling, bruising, temporary sensation changes, etc. | Whether written information is provided during consultation |
Even if the device has the same name, the actual treatment plan differs if the treatment area, depth, and pain management vary. Consultation records should specify the exact treatment areas like jawline, cheeks, and neck rather than broad terms like "entire face" so that costs and treatment details can be verified later.
04 When Ultherapy is Appropriate and When to Compare Other Options
If facial and neck sagging is mild and you want lifting without incisions, Ultherapy is worth considering. In the same research, there was no clear difference in effectiveness compared to Thermage-class radiofrequency, but Ultherapy was more painful. If you are sensitive to pain, you should evaluate both devices' anesthesia methods and treatment scope together. If sagging is significant, the jawline needs definite lifting, or longer duration than 6 months is most important, it is appropriate to also compare surgical methods like facelift.
05 Common misconceptions
This is not a procedure that lasts for life. Current research has only confirmed results for approximately 6 months, so the duration of effects beyond that is unknown, and aging continues to progress.
A lower score in sagging reduction does not make one device better than another. In the table, the 180 score for radiofrequency appears lower, but the research conclusion was that the difference in effectiveness between the two methods was not clear. This is why you need to look at the overall comparison results rather than a single number.
06 In summary
Conclusion Ulttherapy is worth considering when you want to improve mild facial and neck sagging without incisions and when you value the ability to see skin layers on ultrasound imaging during the procedure. Since research has confirmed results for approximately 6 months, if long-term durability is your primary concern or if you have significant sagging, you should also consider other lifting methods.
07 Frequently Asked Questions
When does Ulttherapy show results?
Changes were measured starting at approximately 1 month for the face and upper neck, and approximately 3 months for the neck. In two studies, these changes persisted for approximately 6 months, but since there were 20 participants in each study, we cannot predict the magnitude of changes for individual patients.
Does Ulttherapy's effect last permanently after one treatment?
Research has confirmed results for approximately 6 months. There is no follow-up data beyond that point, so we cannot confirm that results last for a year or longer, and since aging continues to progress, this is not a one-time procedure that provides lifelong results.
Is Ulttherapy painful?
It may feel more painful than radiofrequency treatments like Thermage. In a direct comparison study of neck sagging treatment, pain was greater during Ulttherapy, but since experiences vary by individual, the perceived pain level can differ depending on the anesthesia and pain management methods used.
Are Ulttherapy and Thermage the same procedure?
They are procedures with different mechanisms. Ulttherapy focuses ultrasound energy on a single point beneath the skin, while Thermage heats a wider layer using radiofrequency. In direct comparison studies, the difference in sagging improvement was not clear, but pain was greater with Ulttherapy. Detailed differences can be found in Ulttherapy vs. Thermage Comparison.
How do I choose a clinic for Ulttherapy treatment?
You should compare the actual provider and device model, treatment plan by area, pain and adverse effect management, and total cost on the same terms. The verification order is outlined in How to Choose a Lifting Clinic.

09 Terminology
- RCT (Randomized Controlled Trial): A research method with relatively high reliability in which participants are randomly divided into groups for comparison.
- Control Group Study: A study in which a separate comparison group (control group) is established alongside the treatment group. Without a control group, it is difficult to determine whether improvements result from the procedure or other factors.
- Meta-analysis: An analytical method that statistically combines results from multiple individual studies to derive a single conclusion.
- HIFU / MFU-V: A method that focuses ultrasound energy on a single point beneath the skin to generate heat. The surface remains untreated while deeper layers are stimulated.
