Ultraformer: key facts
| Fact | Detail | Source |
|---|---|---|
| What it is | Ultraformer is a line of HIFU devices made by CLASSYS. The current Ultraformer MPT (Micro-Pulsed Technology) has 10 interchangeable cartridges: face 1.5, 2.0, 3.0 and 4.5 mm; body 6.0, 9.0 and 13 mm; energy 0.1 J to 2.0 J; the maker states MP mode delivers energy 2.5 times faster than normal mode. | CLASSYS, 2026 |
| How it works | Ultrasound energy turns to heat, making small thermal zones (about 1 mm³) at about 60 to 70 °C at set depths: 1.5 mm in the dermis, 3 mm below it and 4.5 mm at the SMAS. This leads to collagen contraction and then new collagen. | Contini et al., 2023 |
| Sessions and timing | Studies evaluated single sessions; an Ultraformer study gave 41 patients one treatment of 300 lines at 4.5 mm and 3.0 mm. Remodelling begins around day 28, and improvement persisted up to at least 3 months; in the Ultraformer study, tightening at 2 months was better than at 4 months. | Contini et al., 2023; Lee et al., 2015 |
| Downtime | In the Ultraformer study, slight redness and swelling in 35 of 38 patients and moderate in 3, all resolving within 2 days. | Lee et al., 2015 |
| What it treats | Mildly to moderately lax facial skin; results were weaker with excessive laxity and a BMI above 30. | Contini et al., 2023 |
| Main risks | Redness with or without swelling in nearly all patients; about 2% (14 of 573) had bruising, transient altered sensation, wheals, skin burns, white linear striae or white papules; average pain about 3.8 out of 10. | Contini et al., 2023 |
| Cost at SkinRev Lab | HIFU on the Ultraformer MPT is priced at consultation. | SkinRev Lab |
| Who performs it at SkinRev Lab | Dr Sin Yong, medical adviser, after a consultation; a session takes about 30 to 60 minutes depending on the areas. | SkinRev Lab |
What is Ultraformer MPT?
Ultraformer MPT is a high-intensity focused ultrasound (HIFU) device made by CLASSYS, a Korean medical device company. MPT stands for Micro-Pulsed Technology. The device focuses ultrasound energy at a chosen depth under the skin through interchangeable cartridges, without needles or incisions.
For how HIFU compares with laser and RF options, see our HIFU face lift Singapore guide.
VF Lift is a separate radiofrequency treatment on Volnewmer, with no focused ultrasound.
For who the device suits, how lines are planned and the aftercare, see our HIFU treatment Singapore guide.
At SkinRev Lab, Ultraformer MPT is the device named on our HIFU treatment page. Dr Sin Yong, our medical adviser, performs HIFU himself after a consultation at CityLink Mall, by City Hall MRT. HIFU is priced at consultation, so this page carries no price.
This guide explains the device. It covers:
- how focused ultrasound heats tissue at a set depth;
- the cartridges, depths and modes that CLASSYS publishes;
- how the device is used at SkinRev Lab, as our HIFU page describes it;
- what a session and the days after it involve;
- what published research has measured, and its limits;
- who is usually asked to wait or choose something else.
Facts about the device come from the maker's product page or from journal papers listed under References. Statements about SkinRev Lab come from our own treatment pages and nothing is added to them. One clarification early: Ultraformer MPT is not part of VF Lift, which our site describes as a radiofrequency-only treatment on a different CLASSYS device.
How does focused ultrasound work in the skin?
Focused ultrasound works by concentrating sound waves at a point below the skin surface, where the energy turns into heat; the skin above the focal point is passed through without the same heating. Each pulse leaves a small spot of heated tissue, and a treatment places many of these in rows.
- Thermal coagulation points. CLASSYS explains that protein begins to denature above 60°C, creating what it calls a thermal coagulation point. A 2023 systematic review of microfocused ultrasound describes the same idea: small zones of thermal injury, about one cubic millimetre each, placed at set depths.
- Depth is chosen by cartridge. The focal depth is fixed by the cartridge fitted to the handpiece. The review describes about 1.5 mm as reaching the dermis, 3 mm the layer beneath it, and 4.5 mm the SMAS, the fibrous layer over the facial muscles.
- The response takes time. The review reports immediate contraction of heated collagen, followed by new collagen and elastin forming as the skin repairs. Our HIFU page gives about two to three months for new collagen to form.
Because the heat is placed in points instead of spread through a block of tissue, depth selection matters. The energy has to match the thickness of the skin and the fat beneath it in each part of the face, which is why the plan is drawn up after an examination and why HIFU at SkinRev Lab is a medical treatment performed by a doctor.
What does CLASSYS publish about Ultraformer MPT?
CLASSYS publishes the energy type, the output range, ten interchangeable cartridges at seven focal depths, and the delivery modes for Ultraformer MPT. The table repeats those published specifications.
| Feature | What the maker states |
|---|---|
| Energy type | High-intensity focused ultrasound (HIFU) |
| Output per pulse | 0.1 J to 2.0 J, adjustable in 0.1 J steps |
| Cartridges | Ten, interchangeable |
| Face cartridges | Focal depths of 1.5 mm, 2.0 mm, 3.0 mm and 4.5 mm |
| Body cartridges | Focal depths of 6.0 mm, 9.0 mm and 13 mm |
| Booster cartridges | 1.5 mm, 3.0 mm and 4.5 mm, delivering energy in a circular pattern |
| Normal mode | Energy delivered to the target in a dot pattern |
| MP mode | Described as broad heating of the coagulation zone, delivered at 2.5 times the speed of normal mode |
| Handpieces | Two plus one, interchangeable |
The maker describes the standard face cartridges as delivering energy in a linear pattern, and says the operator decides the number of pulses from factors such as asymmetry and the degree of sagging.
Some figures people look for are not on the maker's product page: the ultrasound frequency of each cartridge in MHz, the spacing between pulses and the number of pulses in a session. This page does not supply them from other sources. Which cartridges are used on your face, and how many lines, is a decision made at consultation.
What do the cartridge depths and MP mode mean?
The cartridge depth is the distance below the skin surface at which the ultrasound comes to a focus, and MP mode is a way of delivering the pulses more quickly along each line. Neither is a setting a patient chooses; both are part of the doctor's plan.
Depths on the face. Our HIFU page states that cartridges on the face commonly focus at 1.5 mm, 3.0 mm and 4.5 mm, and that the 4.5 mm depth reaches the SMAS. In plain terms:
- 1.5 mm sits within the skin itself, in the upper dermis.
- 3.0 mm sits at the lower dermis and the layer just beneath it.
- 4.5 mm reaches the SMAS in areas where the tissue is thick enough.
Skin and fat thickness vary across the face and between people. A depth that suits a full cheek may not suit a thin temple or the area beside the mouth, so the map of depths is individual.
Body depths. The maker lists 6.0 mm, 9.0 mm and 13 mm cartridges for the body. Our HIFU page says the deeper cartridges are kept for body areas.
MP mode. In normal mode the maker describes energy arriving as separate dots. In MP mode it describes broad heating of the coagulation zone, delivered at 2.5 times the speed of normal mode. The maker's page does not explain the pulsing in more technical detail, so we do not either.
Booster cartridges. The maker also lists booster cartridges with a circular pattern. Our HIFU page does not describe using them, so this page makes no statement about them at SkinRev Lab.
How is Ultraformer MPT used at SkinRev Lab?
At SkinRev Lab, Ultraformer MPT is used for the medical HIFU treatment, and Dr Sin Yong performs it himself after a consultation. Our HIFU page and technology page both name the device.
The HIFU page describes the treatment in these terms:
- Planned per area. The number of lines and the cartridge depths are set for each area at consultation.
- Session length. About 30 to 60 minutes, depending on the areas treated.
- Who it suits. Mild to moderate laxity with reasonable skin quality.
- Sessions. The number is decided individually. Many people are reviewed two to three months later before any maintenance is planned.
- Price. Given at consultation and not published.
The page is also direct about limits. It warns that over-treating a thin face can deepen hollows, and that heavy sagging with excess skin is unlikely to respond well. Those are reasons a doctor may advise fewer lines, a different treatment or none.
Two related treatments are worth separating from this one:
- VF Lift is Dr Sin Yong's radiofrequency treatment on Volnewmer, a different CLASSYS device. It contains no focused ultrasound, so Ultraformer MPT is not part of it.
- SKINLIFT® is a non-medical ultrasound treatment on N Pulse-Ultrasound, performed by our Aesthetic Therapists. It is not medical HIFU; our SKINLIFT and HIFU comparison explains the difference.
Ultherapy, another maker's focused ultrasound device, is not offered at SkinRev Lab.
What happens during and after an Ultraformer MPT session?
A session starts with a consultation and examination, then the doctor places rows of ultrasound pulses across the planned areas, changing cartridges to change depth. Our HIFU page gives about 30 to 60 minutes.
Before the session, the HIFU page advises:
- no fillers or wrinkle-relaxing injections in the area for two weeks beforehand;
- stopping retinoids and exfoliating acids one week beforehand.
During the session
- The skin is cleansed and ultrasound gel is applied so the cartridge couples with the skin.
- Each line is felt as a brief, deep prickling or warmth, more noticeable over bone such as the jawline. Tell the doctor how each area feels, because energy can be adjusted.
- Cartridges are swapped as the plan moves from one depth to another.
Afterwards, the HIFU page describes little downtime:
- mild redness, swelling or tenderness for a few hours to a few days;
- no hot showers on the face, saunas, alcohol or very hot exercise until any swelling settles;
- sunscreen every day;
- retinoids resumed after five to seven days if the skin is calm.
Contact the clinic if you notice a welt or raised line, a blister or burn, numbness or tingling that does not ease, weakness when moving part of the face, or a new dent or hollow. These are uncommon and should be examined. Our guide to HIFU side effects and aftercare covers the recovery period in more detail, and your doctor will advise on anything specific to you.
Ultraformer side effects and pain: how often they happen
Ultraformer treatment is uncomfortable for many people, and the common side effects are short-lived. These figures come from HIFU studies in Asian patients; they did not all use Ultraformer MPT.
| Effect | How often it was reported | Study |
|---|---|---|
| Pain rated severe | 54.4% of 68 treatment sessions in 49 Chinese patients | Chan et al., 2011 |
| Average pain across studies | Pooled mean pain score 4.85 (785 patients, focused ultrasound with visualisation) | Amiri et al., 2024 |
| Focal bruising | Up to 25% of treatment sessions | Chan et al., 2011 |
| Dark marks (PIH) | 2 cases, on the forehead, at 1 month | Chan et al., 2011 |
| Redness and swelling | 6 of 20 patients; purpura and bruising in 2 | Park et al., 2015 |
| Serious, lasting or delayed effects | None noted up to 6 months | Chan et al., 2011 |
Rarer problems such as blistering, skin breakdown and swelling under the skin have been reported in case series (Friedmann et al., 2018). At SkinRev Lab, numbing cream may be applied before HIFU, and cartridges are set to specific depths.
What does the research on Ultraformer MPT show?
Published research covers focused ultrasound as a class reasonably well for short-term follow-up, and this particular device in a smaller number of studies. It is worth being exact about what each measured.
A study of this device. A 2024 paper in Plastic and Reconstructive Surgery Global Open studied Ultraformer MPT in 50 patients, using five cartridges with micro-pulsed mode options chosen according to ultrasound imaging of each person's anatomy. A three-dimensional scanner measured the position of seven areas of the face before and immediately after treatment. The measurements were taken straight after the session only, so the paper does not show what remains weeks or months later.
Focused ultrasound as a class. A 2023 systematic review of microfocused ultrasound for facial skin tightening pooled side effects across its included studies. Temporary redness, with or without swelling, occurred in almost all patients. Less common events, such as bruising, altered sensation, burns, a welt and white lines on the neck, were recorded in 14 of 573 treated patients, about 2%. The authors also reported that the response declined with greater laxity and higher body mass index.
A wider review. A 2025 systematic review in Aesthetic Surgery Journal covering 45 studies of HIFU for skin tightening and body contouring noted that protocols and settings vary widely between studies, that results depend on the operator, and that durability beyond 12 months is not established. It lists nerve irritation and unintended loss of fat as rare events, and links the loss of fat to improper depth selection.
These reviews cover several devices, not Ultraformer MPT alone. This page therefore makes no claim about results, and a consultation will not promise one.
How often Ultraformer is repeated, and how long results take
Ultraformer results build over weeks to months, and repeat treatment is usually considered from 12 months onwards (Singapore General Hospital). The timeline below combines that guidance with what HIFU studies measured.
| When | What usually happens | Source |
|---|---|---|
| Same day | Redness usually settles within a few hours | Singapore General Hospital |
| First days | Any swelling settles after several days | Singapore General Hospital |
| Day 30 to day 180 | In a 20-person split-face trial of focused ultrasound vs monopolar RF, aesthetic improvement scores showed improvement at days 30, 90 and 180 | Alhaddad et al., 2019 |
| 3 and 6 months | In 20 Korean patients after a single HIFU session, two blinded clinicians rated seven face areas at 3 and 6 months | Park et al., 2015 |
| 12 months onwards | Repeat treatment considered | Singapore General Hospital |
How many sessions: a safety study in 49 Chinese patients used one to three full-face treatments (Chan et al., 2011). At SkinRev Lab, Dr Sin Yong, medical adviser, usually reviews the result two to three months after the session before discussing a repeat; Ultraformer MPT HIFU is priced at consultation.
Who is Ultraformer MPT suited to, and who should wait?
Our HIFU page describes the treatment as suiting mild to moderate laxity with reasonable skin quality, and as unsuitable in pregnancy, over active infection or open wounds, and over implanted electronic devices. Suitability is decided by Dr Sin Yong at consultation, after examining the face and taking a medical history.
Two situations are flagged on the HIFU page because focused ultrasound may be the wrong tool:
- A thin face. Over-treating a face with little fat can deepen hollows. The plan may use fewer lines or avoid the deeper cartridge in some areas, or the doctor may advise against HIFU.
- Heavy sagging with excess skin. This is unlikely to respond well, and a surgical opinion may be the more useful next step.
Tell the doctor about anything else that could matter:
- fillers, threads, wrinkle-relaxing injections or surgery in the area, and when you had them;
- implants or metalwork in the face or jaw;
- a history of cold sores, keloids or slow healing;
- medicines that thin the blood or affect healing;
- skin conditions that are active in the area.
If the concern is mainly skin texture, pigment or volume loss, focused ultrasound does not address it and another treatment will be discussed. If you would prefer a non-medical option, SKINLIFT® is performed by our Aesthetic Therapists and is a separate treatment from medical HIFU.
Ultraformer vs Ultherapy vs RF lifting
Ultraformer MPT, Ultherapy and monopolar radiofrequency (RF) all heat tissue under the skin to tighten it, but they use different energy and suit slightly different needs. Here is how they compare on what can be checked.
| Ultraformer MPT (HIFU) | Ultherapy (MFU-V) | Monopolar RF (VF Lift on Volnewmer) | |
|---|---|---|---|
| Energy | Focused ultrasound at set depths | Focused ultrasound with on-screen imaging | Radiofrequency heat, no ultrasound |
| Face depths | 1.5, 3.0 and 4.5 mm cartridges | Set depths (not offered here) | Heats the dermis and fibrous septa |
| Evidence | HIFU studies such as Park et al., 2015 | Review of 42 studies: 84% of 326 patients with satisfaction data reported some satisfaction (Amiri et al., 2024) | A split-face trial against focused ultrasound (Alhaddad et al., 2019) |
| At SkinRev Lab | Offered; Dr Sin Yong, priced at consultation | Not offered | Offered as VF Lift; Dr Sin Yong, priced at consultation |
How the choice is usually made: focused ultrasound reaches the deeper support layer that HIFU cartridges target, while RF suits people who want skin tightening with no ultrasound. Some plans use both: a 24-person Korean split-face study compared monopolar RF followed by HIFU with the reverse order, assessed at days 30 and 90 (Choi et al., 2025).
How do I ask about Ultraformer MPT at SkinRev Lab?
Ask for a HIFU consultation with Dr Sin Yong; HIFU is the treatment at SkinRev Lab that uses Ultraformer MPT. Suitability, the areas, the number of sessions and the price are set out at that consultation, since medical treatments here are priced at consultation.
Useful questions to bring, here or anywhere you are considering HIFU:
- Which device and which cartridges will be used on my face?
- Who will perform the treatment?
- Which areas will you avoid, and why?
- How many lines are planned, and can the energy be adjusted as we go?
- What should I expect in the first few days, and what should prompt a call?
- What would make you advise against HIFU for me?

Common questions
Your questions,
answered
What is Ultraformer MPT?
Ultraformer MPT is a high-intensity focused ultrasound (HIFU) device made by CLASSYS. MPT stands for Micro-Pulsed Technology. It focuses ultrasound at a set depth under the skin through interchangeable cartridges, creating small points of heat without needles or incisions. At SkinRev Lab, Dr Sin Yong uses it for the medical HIFU treatment.
Does SkinRev Lab offer Ultraformer MPT in Singapore?
Yes. Our HIFU treatment page names Ultraformer MPT by CLASSYS as the device used at SkinRev Lab, CityLink Mall, by City Hall MRT. Dr Sin Yong, medical adviser, performs the treatment after a consultation at which the cartridge depths and number of lines are set for each area.
How much does Ultraformer MPT cost at SkinRev Lab?
HIFU at SkinRev Lab is priced at consultation, so we do not publish a figure. The price depends on the areas treated and the plan Dr Sin Yong sets after examining your face. You can arrange a consultation by WhatsApp on +65 8266 9585.
What depths does Ultraformer MPT treat?
CLASSYS lists face cartridges with focal depths of 1.5 mm, 2.0 mm, 3.0 mm and 4.5 mm, and body cartridges at 6.0 mm, 9.0 mm and 13 mm. Our HIFU page says 1.5 mm, 3.0 mm and 4.5 mm are commonly used on the face, with 4.5 mm reaching the SMAS layer.
What does MP mode mean on Ultraformer MPT?
MP stands for micro-pulsed. CLASSYS describes normal mode as delivering energy in a dot pattern and MP mode as broad heating of the coagulation zone, delivered at 2.5 times the speed of normal mode. Whether MP mode is used, and where, is part of the doctor's plan for each face.
Is Ultraformer MPT the same as Ultherapy?
No. They are separate focused ultrasound devices from different makers, each with its own cartridges or transducers and settings. SkinRev Lab offers HIFU on Ultraformer MPT and does not offer Ultherapy. Our Ultherapy and HIFU guide describes both by their published specifications.
Is Ultraformer MPT used in VF Lift?
No. Our VF Lift page describes VF Lift as a radiofrequency-only treatment on Volnewmer, a different CLASSYS device, with no focused ultrasound. Ultraformer MPT is used for the separate HIFU treatment. Dr Sin Yong performs both, and which one is appropriate is decided at consultation.
What is the downtime after Ultraformer MPT HIFU?
Our HIFU page describes little downtime: mild redness, swelling or tenderness for a few hours to a few days. Hot showers on the face, saunas, alcohol and very hot exercise are avoided until swelling settles, sunscreen is used daily, and retinoids are resumed after five to seven days if the skin is calm.
Questions people ask
Is Ultraformer the same as HIFU?
Ultraformer is a brand; HIFU, high-intensity focused ultrasound, is the technology. Ultraformer is the CLASSYS line of HIFU devices, and the Ultraformer MPT is its current model; other makers produce other HIFU devices. At SkinRev Lab, Dr Sin Yong, medical adviser, performs HIFU on the Ultraformer MPT, priced at consultation.
How long does Ultraformer last?
Studies follow results for months, not years. A systematic review of single microfocused ultrasound sessions found improvement that continued up to one year, while an Ultraformer study found tightening at 2 months was better than at 4 months. At SkinRev Lab, many people are reviewed two to three months later before any maintenance is planned.
How often can I do Ultraformer?
Usually about once a year. Repeat treatment is usually considered from 12 months onwards (Singapore General Hospital). At SkinRev Lab, Dr Sin Yong, medical adviser, reviews the result two to three months after a session before any repeat is planned, and HIFU is priced at consultation.
Does Ultraformer hurt?
Many people find it uncomfortable. In a study of 49 Chinese patients, pain was rated severe in 54.4% of focused ultrasound sessions (Chan et al., 2011), and a meta-analysis of a related focused ultrasound device (785 patients) found a pooled mean pain score of 4.85 (Amiri et al., 2024). Numbing cream and adjusted settings help.
What are the side effects of Ultraformer?
Mostly short-lived redness, swelling and bruising. In a HIFU safety study, focal bruising occurred in up to 25% of sessions, two people had temporary dark marks and no serious lasting or delayed effects were noted up to six months (Chan et al., 2011). Blistering and skin breakdown are rare and reported in case series.
