Key takeaways
- PRIME is a console update, not a new treatment: FDA's summary describes identical ultrasound energy and treatment guidelines.
- Ultherapy is FDA-cleared, not FDA-approved, and its labeling describes "temporary changes" in the skin's appearance.
- Merz's "20% faster" session claim comes from a survey of providers, not an FDA measurement.
- We found no national price for Ultherapy or PRIME, so a written quote is the number to work from.
What is Ultherapy PRIME?
Ultherapy PRIME is the console used to deliver Ultherapy, the brand name for the Ulthera System, an ultrasound skin-lifting device sold by Merz Aesthetics.
The device was first authorized by FDA through the De Novo pathway (DEN080006) in September 2009, and later treatment areas were added through 510(k) clearances.
De Novo and 510(k) are device pathways, so Ultherapy is an FDA-cleared device, not an FDA-approved one.
The site's Ultherapy guide covers the device itself in depth.
The cleared labeling describes the intended use as applying focused ultrasound energy to the body to achieve "temporary changes in the physical appearance of the skin." Treatment uses transducers that work at fixed depths of 1.5 mm, 3.0 mm or 4.5 mm, and the system's DeepSEE imaging can visualize tissue up to 8 mm below the skin surface.
Those details come from the current instructions for use, which are written for the PRIME system.
PRIME carries the device's current cleared indications: to lift the eyebrow; lift lax submental (under-chin) and neck tissue; improve lines and wrinkles of the décolleté; and improve the appearance of skin laxity on the abdomen, anterior arms, posterior arms and knees.
The knee indication is the newest, cleared in May 2026.
An area outside that list is not a cleared use of the device, whatever a treatment menu says.
FDA's De Novo and 510(k) pathways clear a device for the uses it lists; they do not "approve" it the way a drug is approved. If marketing calls Ultherapy "FDA-approved," the term is wrong — cleared (or authorized) is the accurate word.
What changed vs the original Ultherapy?
FDA cleared the PRIME console — formally the UC-1 Control Unit PRIME — on February 22, 2024, under 510(k) number K233996.
The agency's summary calls it a console modification with identical ultrasound signal energy and treatment guidelines to the earlier system, and the cleared indications were unchanged.
The differences the summary lists: updates to the console's industrial design, modernized graphics in the on-screen interface, and hardware updates to meet current electromedical standards and replace parts reaching end of life.
FDA's summary says those changes do not significantly affect clinical functionality or performance.
A second update followed.
The PRIME Model 2.1 (K250418) was cleared on May 13, 2025, adding wireless connectivity and a treatment-planning mode called SEE.PLAN.TREAT., again with identical ultrasound signal energy.
The two PRIME clearances
| Console | 510(k) / cleared | What changed | Ultrasound energy |
|---|---|---|---|
| UC-1 Control Unit PRIME | K233996 / Feb 22, 2024 | Industrial design, on-screen graphics, hardware updates | Identical to the earlier system |
| PRIME Model 2.1 | K250418 / May 13, 2025 | Wireless connectivity, SEE.PLAN.TREAT. planning mode | Identical to the earlier system |
The only performance figure our research turned up for PRIME is Merz's own.
The company's site says PRIME offers a "20% faster" session than legacy Ultherapy with the same lifting results, and the site's footnote says that figure is the average reported increase in system speed from a survey of providers.
It is a manufacturer claim from a provider survey, not a measurement FDA made.
FDA's summary describes PRIME's ultrasound signal energy and treatment guidelines as identical to the earlier system's. The changes it lists are design, graphics and hardware ones — no stronger or deeper energy, no better-results finding — so a claim that PRIME works better is a marketing claim, not an FDA finding.
Results and comfort
The results timeline attached to PRIME is the manufacturer's.
Merz says most patients see results after one Ultherapy PRIME session, with some initial lift but final results developing over 2 to 3 months.
The company says facial results "can last up to a year or more," and up to 6 months for the abdomen and arms.
Those are Merz's descriptions for the device, not study results for any one person.
On comfort, Merz's FAQ says a session takes about 30 to 90 minutes depending on the area treated, that patients may feel heat or tingling while the energy is delivered, and that there is no downtime — its FAQ adds that redness typically fades within a few hours and some patients have slight, temporary swelling, tingling or tenderness.
The device's instructions for use fill that picture out with the face and neck trials: redness usually resolving within hours, swelling within 3 to 72 hours, welting within a week, bruising and tenderness within 2 days to 2 weeks, and transient muscle weakness or numbness from nerve inflammation typically resolving in 2 to 6 weeks.
No permanent facial nerve injuries were reported in those trials.
Side effects in the face and neck trials
| Effect | Typically resolved |
|---|---|
| Redness | Within hours |
| Swelling | Within 3 to 72 hours |
| Welting | Within a week |
| Bruising and tenderness | Within 2 days to 2 weeks |
| Muscle weakness or numbness (nerve inflammation) | In 2 to 6 weeks |
The cleared energy and treatment guidelines are the same as the original system's, and the labeling above — the intended use of "temporary changes" in the skin's appearance and the trials' side-effect timeline — is the device's current labeling, written for the PRIME console.
What the clinical trials measured, checkpoint by checkpoint, is on our Ultherapy before-and-after page.
The instructions for use warn that burns, which may or may not cause permanent scarring, can occur with incorrect technique — for example tilting the transducer, incorrect line spacing or gel pockets. Post-market reports listed in the labeling include fat or volume loss, nerve effects lasting months and vision changes; their frequency cannot be reliably estimated from those reports.

What does Ultherapy PRIME cost?
We found no national number to check a quote against.
In our research we did not find a national price range for Ultherapy overall or for the PRIME console specifically, and we did not find a cost page for nonsurgical skin tightening on the American Society of Plastic Surgeons' site.
With no sourced figure, the written quote in front of you is the number to work from.
On the title question — whether PRIME costs more than the original — nothing sourced says it should.
FDA's summary describes the same treatment delivered through a redesigned console, with identical energy and unchanged indications, and the changes the two 510(k) summaries list are design, graphics and hardware ones in 2024 and software ones in 2025 — not prices.
A practice that prices PRIME sessions differently from the earlier system is making its own pricing decision.
When you collect quotes, ask which console the practice uses and what the price includes.
Two more money notes.
The American Academy of Dermatology puts non-invasive skin tightening — ultrasound, radiofrequency and some lasers — in the not-covered-by-insurance column, and the cleared labeling frames Ultherapy as a cosmetic change — "temporary changes in the physical appearance of the skin." If you would rather spread the cost out, our med spa financing page compares the payment options.

Frequently asked questions
Is Ultherapy PRIME FDA-approved?
No. Ultherapy is an FDA-cleared device, first authorized through the De Novo pathway in September 2009, with later treatment areas added by 510(k) clearances.
The PRIME console itself was cleared in February 2024, and the Model 2.1 update followed in May 2025.
De Novo and 510(k) devices like Ultherapy are cleared or authorized, not "FDA-approved."
Does Ultherapy PRIME work better than the original Ultherapy?
FDA's 510(k) summary describes identical ultrasound signal energy and treatment guidelines, with changes limited to industrial design, on-screen graphics and hardware that the agency says do not significantly affect clinical functionality or performance.
Merz says PRIME runs sessions 20% faster, a figure from its survey of providers.
There is no FDA finding that PRIME produces better results.
How much does Ultherapy PRIME cost?
We did not find a national price range for Ultherapy or for the PRIME console in our research, so there is no sourced figure for what a session should cost or for a PRIME premium over the original.
The American Academy of Dermatology says non-invasive skin tightening is not covered by insurance.
Ask each practice for a written quote that says exactly what it includes.
What is SEE.PLAN.TREAT. on Ultherapy PRIME?
It is the treatment-planning mode the 2025 Model 2.1 update added, along with wireless connectivity.
FDA's summary for that clearance again describes the ultrasound signal energy as identical to the earlier system's.
So the mode is a planning workflow on the console; the cleared labeling still describes the treatment as producing "temporary changes in the physical appearance of the skin."
