If you have noticed skin losing elasticity or softening along the jawline, you may wonder whether skin can be firmed without surgery. Understanding how Ultherapy Prime operates can help address that question.
Ultherapy Prime is designed to deliver micro-focused ultrasound energy beneath the skin surface without making incisions, focusing energy at targeted depths. At the focal point, tissue reaches a temperature that induces controlled collagen denaturation, initiating a natural healing response. Over the subsequent weeks, active fibroblasts synthesise new collagen and elastin, aiming to support the skin’s underlying structural framework.
That deep focal point targets the superficial musculoaponeurotic system (SMAS), a fibromuscular layer traditionally repositioned during a surgical facelift. Ultherapy Prime in Singapore aims to influence this structural layer non-invasively.
The Science of Micro-Focused Ultrasound
Many energy-based aesthetic procedures work primarily on the skin surface or within the upper dermis. Micro-focused ultrasound with visualisation (MFU-V) uses a different approach to energy placement.
To understand the mechanism, consider how a magnifying glass focuses sunlight onto a single point below. The light passes through the glass without damaging it, but concentrates at a focal point underneath. Ultrasound energy behaves similarly: the outer skin layer (epidermis) remains untouched, while energy concentrates at a precise focal depth where tissue temperature reaches approximately 60°C to 70°C.
Published literature in the Journal of Cosmetic Dermatology identifies 60°C to 70°C as the temperature threshold required for collagen denaturation and subsequent neocollagenesis. This energy is delivered at targeted depths of 1.5 mm, 3.0 mm, and 4.5 mm.
Each focal point forms a thermal coagulation point (TCP). These small TCPs are spaced evenly apart, separated by undisturbed tissue. The surrounding untreated tissue supports the natural recovery process.
What Happens Beneath the Skin After a Session
Following an MFU-V session, the body undergoes a multi-phase biological response:
- Days 0 to 7: Collagen fibres at the focal points undergo initial thermal denaturation. Some individuals may report a temporary sensation of tightness during this early phase, though this reflects initial thermal effects rather than final remodelling.
- Weeks 1 to 4: Fibroblasts migrate to the target areas and begin synthesising structural proteins.
- Months 2 to 3: New Type I and Type III collagen synthesis typically reaches its primary phase during this timeframe.
- Months 3 to 6: Tissue remodelling continues, supporting gradual changes in firmness and skin density.
Because this is a gradual biological response, the timeline and degree of change differ from person to person based on age, lifestyle, baseline tissue health, and individual biology.
The SPT (See, Plan, Treat) Protocol
Ultherapy Prime works by following the SPT (See, Plan, Treat) protocol, a structured clinical approach that uses real-time ultrasound imaging at every stage.
SEE
Before any energy is delivered, the device’s handpiece is used to visualise the tissue layers beneath your skin. The SMAS depth, tissue thickness, and structural anatomy specific to your face are all assessed and documented.
PLAN
Based on what is seen, a personalised treatment map is established, determining which transducer depths to use, how many lines of energy to deliver, and which zones to prioritise for your individual anatomy and clinical goals.
TREAT
Energy is then delivered systematically, guided by the imaging data gathered during the SEE and PLAN stages. This anatomy-guided approach is designed to help each pulse reach the intended tissue layer.
Every Ultherapy Prime session at Glowwis is guided by Dr Sam Pradeep, trained and certified in the SPT protocol, with 10 years of extensive experience in aesthetic medicine. This mapping process is a standard part of every Ultherapy Prime session.
Targeted Treatment Depths
Depth is changed by swapping transducers. Each one focuses at a fixed distance beneath the skin.
| Transducer depth |
Tissue layer reached |
Clinical purpose |
| 4.5 mm |
SMAS / fibromuscular layer |
Structural lift; the layer addressed in facelift surgery |
| 3.0 mm |
Deep and mid dermis |
Firmness, dermal thickening, fine line softening |
| 1.5 mm |
Superficial dermis |
Skin texture and surface quality |
A treatment plan usually layers these depths across a single session rather than relying on one alone, because laxity is rarely confined to a single tissue plane.
Clinical Applications: Face, Neck and Body
Skin laxity is not confined to the face, and neither is the treatment.
- Face. Brow position, midface support, jawline definition and early jowl formation.
- Neck. Submental laxity and horizontal neck lines. The platysma is thin here, which is precisely why depth verification is important. We cover this area separately in Ultherapy Prime for neck tightening in Singapore.
- Décolletage. Chest skin is subject to cumulative ultraviolet exposure. In Singapore’s equatorial UV index, this area often shows change earlier than patients expect.
- Body. Protocols extend to the upper arms, abdomen and knees, where skin has lost tone but the priority is firmness rather than volume reduction.
The Treatment Process, Step by Step
Before your session, your suitability is assessed in consultation. Tell Dr Sam about any medical conditions, implanted devices, active skin infections in the treatment area, or medications you take, including blood thinners and isotretinoin. Some of these affect timing or suitability.
On the day
- The skin is cleansed, and ultrasound coupling gel is applied.
- Topical numbing cream is applied and given time to take effect.
- Imaging is performed, and the treatment map is set.
- Energy is delivered. You will feel brief sensations of heat, tingling or a deep prickle as each pulse fires. Each sensation lasts a fraction of a second.
- Gel is removed. Many patients are able to apply make-up afterwards.
Afterwards
Downtime is generally limited. A soft flush, mild tenderness or a hint of swelling may be present and typically settles within a day. Occasionally, tingling or tenderness to touch persists for a week or two. Bruising is uncommon but possible. A systematic review and meta-analysis of MFU-V published in the Aesthetic Surgery Journal reports erythema, oedema, swelling, bruising and tenderness as the commonly recorded adverse events, generally mild to moderate in severity.
Because the result depends on your body’s own collagen response, individual outcomes vary according to skin health, age, degree of laxity and lifestyle factors such as sun exposure and smoking.
Is Ultherapy Prime Right for You?
You may be a candidate if you notice:
- Brow heaviness or upper eyelid hooding
- Softening of the jawline or early jowl formation
- Neck laxity, or crepey texture across the chest
- A preference for gradual change without surgical recovery
Ultherapy Prime may not be appropriate if you have:
- Active infection, open lesions or severe cystic acne in the treatment area
- An implanted electrical device in the treatment field
- Pregnancy, as there is limited safety data
Suitability is determined at consultation, not online. This is a medical assessment.

Commonly Asked Questions
How does Ultherapy Prime feel during treatment?
Patients typically describe brief heat, tingling or a deep prickling sensation as each pulse is delivered. It lasts a fraction of a second. Topical numbing cream is applied beforehand. Sensation is greater at the deeper transducer settings and over bony areas such as the jawline.
How long does an Ultherapy Prime session take?
A full face and neck session commonly runs between 60 and 90 minutes, including numbing time and the imaging and mapping stage. Smaller areas take less.
When will I see results, and how long do they last?
Published reviews describe collagen synthesis peaking around two to three months, with remodelling continuing for up to six months. Duration varies with age, skin condition and the rate at which your own collagen depletes. Maintenance sessions are commonly discussed at annual review. Individual results vary.
Can Ultherapy Prime replace a facelift?
No. It is a non-surgical treatment that acts on the same SMAS layer, but a facelift physically excises and repositions tissue. Ultherapy Prime is generally considered for mild to moderate laxity. Where laxity is advanced, your practitioner will typically advise this and may recommend a surgical opinion.
How many treatment sessions are needed?
This is assessed individually. Some patients are reviewed at three months and require no further intervention that year; others benefit from an additional session or from periodic maintenance. No clinic can determine this before assessing your tissue.
What happens to existing dermal fillers?
Hyaluronic acid fillers and micro-focused ultrasound are frequently planned together to address laxity and volume separately, though timing matters. Where both are wanted in the same visit, MFU-V is typically performed before filler placement. If filler has already been placed, a waiting period is generally recommended before MFU-V, as treatment soon after injection may affect the filler.
Is there downtime after Ultherapy Prime?
Downtime is generally limited. Mild redness, tenderness or slight swelling may occur and usually settles within a day. Many patients return to normal activity the same day, though this is not guaranteed for every individual.
Is Ultherapy Prime safe?
Micro-focused ultrasound has an established clinical record. The device used at Glowwis Aesthetic & Medical Clinic is listed on the Singapore Medical Device Register, which you can search yourself through the Health Sciences Authority Infosearch portal. These are discussed in full at consultation. The doctor performing your treatment should also appear on the register maintained by the Singapore Medical Council. As with any medical procedure, risks exist, including temporary redness, swelling, tenderness, bruising, and rarely, transient nerve-related effects.
Next Steps
Understanding how Ultherapy Prime works comes down to three ideas: micro-focused ultrasound reaches beneath the skin surface without breaking it, real-time imaging confirms where that energy lands, and the change you eventually see is collagen your own body has built over the following months.
Whether it suits your face depends on your tissue, your degree of laxity and your goals. That cannot be settled from an article. If brow heaviness, a softening jawline or neck laxity is what brought you here, the next step is an assessment where those layers can actually be seen.
