Ultherapy and Ultherapy Prime
Microfocused ultrasound with visualisation · the original 'non-surgical lift'
Merz relaunched the platform as Ultherapy Prime in late 2024 and signed Salma Hayek Pinault as its first global ambassador in 2025, which put the twenty-year-old treatment back in celebrity and 'non-surgical facelift' content.

Does Ultherapy and Ultherapy Prime work?
Established. Prime is a better instrument, not a different treatment. Two systematic reviews with meta-analysis (2023 and 2025) found consistent, modest improvement in facial and neck laxity with high satisfaction, but noted that most trials are small, unblinded and often industry-supported.
- Verdict
- Established Long clinical track record. Results depend on selection and technique more than on the device.
- Evidence base
- 4 PubMed-indexed studies cited below, including systematic reviews.
- Suits
- Mild to moderate laxity of the lower face, brow and neck in people with reasonable skin and fat thickness who want a structural effect without injectables.
- Not for
- Thin, hollow faces, where heat at 4.5 mm can read as further gauntness. Pronounced jowling or neck laxity that only surgery will lift. Anyone buying by the shot count.
- In Singapore
- Ultherapy is HSA-registered and doctor-operated in Singapore; Ultherapy Prime has been available in the region since 2025.

What it is
Ultherapy is microfocused ultrasound with visualisation (MFU-V): focused ultrasound heats small points in the dermis and the SMAS layer at 1.5, 3.0 and 4.5 mm while an ultrasound image shows the physician which layer the transducer is sitting on. Prime is the newer platform with a larger screen, a redesigned handpiece and faster delivery; the energy and the depths are the same.
How it works
Each shot creates a small coagulation point that contracts and then stimulates collagen over two to three months. The imaging is the distinguishing feature: it lets the operator confirm the transducer is coupled and that 4.5 mm is actually reaching the SMAS rather than fat or bone. What varies between providers is the map — how many lines, at which depths, in which zones — and whether the operator reads the image or just counts shots. Prime changes how comfortably and consistently the energy is delivered, not what it does.
What the evidence says
Two systematic reviews with meta-analysis (2023 and 2025) found consistent, modest improvement in facial and neck laxity with high satisfaction, but noted that most trials are small, unblinded and often industry-supported. A 2025 systematic review of adverse events found that serious complications are uncommon and that fears of MFU-V compromising a later facelift are not supported by published data. Evidence specific to Prime is so far a pilot case series from Asia-Pacific; its claims rest on the older platform's record. The social complaint of facial fat loss appears in case reports rather than trials and is linked to depth selection in thin faces.
What people are saying

What the studies show
- systematic review
Pooled data showed improvement in facial and neck laxity with a low rate of serious adverse events, with heterogeneity and small samples across trials.
Microfocused Ultrasound With Visualization (MFU-V) Effectiveness and Safety: A Systematic Review and Meta-Analysis. — Aesthet Surg J, 2025. PMID 39540440.
- systematic review
Most studies reported improvement and high satisfaction at three to six months; the authors graded the overall quality of evidence as limited.
A Systematic Review and Meta-Analysis of the Clinical Efficacy and Patients' Satisfaction of Micro-focused Ultrasound (MFU) Treatment for Facial Rejuvenation and Tightening. — Aesthetic Plast Surg, 2023. PMID 37198297.
- systematic review
Adverse events were mostly transient; published evidence did not support the claim that prior MFU-V compromises later facelift surgery.
Microfocused Ultrasound With Visualization: A Systematic Review of Adverse Events and Risk of Subsequent Facelift Compromise. — Dermatol Surg, 2025. PMID 39625163.
- case series
A small Asia-Pacific case series described tolerability and early outcomes with the Prime platform; no comparison with the previous system was made.

Who it suits
Suits
Mild to moderate laxity of the lower face, brow and neck in people with reasonable skin and fat thickness who want a structural effect without injectables.
Not for
Thin, hollow faces, where heat at 4.5 mm can read as further gauntness. Pronounced jowling or neck laxity that only surgery will lift. Anyone buying by the shot count.

| What it is | Ultherapy is microfocused ultrasound with visualisation (MFU-V): focused ultrasound heats small points in the dermis and the SMAS layer at 1.5, 3.0 and 4.5 mm while an ultrasound image shows the physician which layer the transducer is sitting on. | A single large electrode delivers radiofrequency energy that travels through the tissue to a grounding pad, heating the dermis and subcutaneous layer volumetrically. | High-intensity focused ultrasound delivers heat to precise points at set depths — commonly 1.5, 3.0 and 4.5 mm — creating coagulation points in the dermis and the SMAS layer that contract and stimulate collagen over months. |

| Suits | Mild to moderate laxity of the lower face, brow and neck in people with reasonable skin and fat thickness who want a structural effect without injectables. | Mild to moderate laxity of the face, eyelids, neck and body; people who prefer a no-needle, no-injectable approach. | Mild to moderate laxity with reasonable skin thickness, people who want a structural effect without injectables. |
| In one line | Prime is a better instrument, not a different treatment. | The device delivers heat; the protocol decides where it goes and in which order. That is the whole difference between tightening and lifting. | HIFU or radiofrequency is the wrong question — they do not do the same job, which is why 3D Facial Reconstruction uses both. |
Risks
Tenderness, swelling and bruising for days; transient numbness or welts; rare nerve irritation or fat loss when deep transducers are used over thin tissue.
In Singapore
Ultherapy is HSA-registered and doctor-operated in Singapore; Ultherapy Prime has been available in the region since 2025. Confirm which platform the clinic is using. Dr Sin Yong is a key opinion leader for CLASSYS and HIRONIC, competing ultrasound manufacturers, disclosed here as an interest.
