Ultherapy Singapore: Ultherapy Prime^®, micro-focused ultrasound with imaging

What Ultherapy is and how it works

Ultherapy is micro-focused ultrasound with visualisation (MFU-V), made by Merz Aesthetics. A curved transducer focuses ultrasound so the beam converges at a fixed distance below the skin, much as a lens focuses light. At that focal point the energy is absorbed as heat, raising a volume of tissue under 1 mm³ to roughly 60–70 °C for a fraction of a second. The skin above the focus receives far less energy and is not broken.

Each pulse produces one thermal coagulation point; the handpiece lays a line of them, and a treatment is a planned pattern of lines. The body repairs each point with new collagen as the coagulated tissue contracts. The lift is biological rather than mechanical, so it develops with collagen remodelling rather than on the day.

The visualisation is the part most patients underestimate. Before each line, DeepSEE® imaging shows the tissue beneath the transducer to a depth of about 8 mm: dermis, fat, SMAS and bone. On a thin temple the SMAS may lie at 3 mm; on a full cheek the 4.5 mm focus may land in fat. Imaging is how those mismatches are seen and corrected before energy is delivered.

Who Ultherapy suits, and who should wait or avoid it

Ultherapy is right for you if your main concern is mild to moderate loose skin in the brow, jawline, under-chin or neck, and your face has kept its volume. It is the wrong tool if the problem is hollowing, heaviness from fat, or a lot of excess skin. Age is not the deciding factor; the tissue is.

A quick self-check helps before you come in. Lift the skin gently at the jaw in a mirror: if the line improves, laxity is part of it. If the cheek above looks hollow, volume is part of it, and ultrasound does not add volume. Skin that hangs in folds is a surgical question. Readers whose concern is the lower face will find jowls and lower-face sagging useful.

Ultherapy treatment areas: brow, jawline, under the chin, neck and décolletage

Ultherapy in Singapore is planned zone by zone, and the depth used in each zone is confirmed on the DeepSEE image before each line rather than assumed. Where the image shows thinner tissue than expected, a shallower transducer is used or the zone is left out.

Zone by zone, the areas treated most often are the brow and forehead, the lower face and jawline, and the under-chin and neck. The décolletage and the skin around the eyes use the superficial depth only. Skin type is discussed on Ultherapy for Asian skin, and who should wait or is directed elsewhere on am I suitable for Ultherapy.

Which to choose: Ultherapy Prime, other HIFU or radiofrequency

These devices are not rivals on a scale. They are different mechanisms for different tissue problems, and Dr Sin Yong performs each of them, so the comparison is about what the energy does, not which is better.

Ultherapy Prime and the Ultraformer MPT share the physics; the difference is design. Ultherapy images the tissue before each line, while the Ultraformer relies on cartridge depth and the physician's reading of anatomy. The wider HIFU category is covered on HIFU, and the platforms side by side on Ultherapy Prime vs Ultraformer MPT vs Shurink. Ultrasound against radiofrequency is compared on Ultherapy vs Thermage and Volnewmer vs Ultherapy.

Why 4D and 7D HIFU are marketing labels rather than generations is explained in the 4D, 7D and 9D HIFU explainer.

What Ultherapy cannot do, and what is paired with it

Ultherapy tightens and lifts tissue that is lax. It does not add volume, remove fat or resurface the skin, and it does not replace a surgical facelift. If the face has hollowed, or the heaviness is fat rather than loose skin, focused ultrasound is directed at the wrong problem, and more of it will not correct that. When a face needs more than tightening, another treatment is paired with it, chosen from the examination rather than a menu.

Hollowing is answered with volume, surface laxity with Thermage FLX, a heavy lower face with the VF Lift – Vertical Facelift, and skin excess with the Bliss Lift or a surgical opinion. How each mechanism is matched to a pattern of descent is set out on sagging face treatment.

Ultherapy results: when they show and how long they last

Ultherapy works through collagen remodelling, so it does not take effect on the day. Some tightness may be felt early from the immediate contraction of collagen, though redness and swelling can blur that. The main change develops gradually as each treated point heals with new collagen, and the pace differs with age, skin quality and the degree of laxity. The response is read at review visits at 4 and 12 weeks.

For planning, Ultherapy is usually a single session, with a repeat considered at 12 to 24 months if it suits and decided from a fresh examination. It is not sold as a package here, and no timetable is promised. These are typical figures for planning; the number for you is decided at the assessment, and results vary.

Does Ultherapy work? What published studies of micro-focused ultrasound measured

Published studies of micro-focused ultrasound, the energy that Ultherapy and Ultherapy Prime deliver, measure lift in millimetres. A 2023 systematic review found 16 eligible studies, all of them in women. After a single treatment, brow lift ranged from 0.47 to 1.7 mm, and the area under the chin on side-view photographs reduced by 26 to 45 mm². In a rater-blinded study of 35 people, the average brow elevation at 90 days was 1.7 mm. In a follow-up of 48 women, doctors graded 77.7% as improved at 180 days, and blinded reviewers graded 67% as improved.

These are averages from small studies that followed people for three to six months. They show a measurable but modest change, which is why suitability is examined first, and they do not predict the result for one face.

Risks and side effects, stated plainly

What is normal. Redness usually settles as the skin cools. Tenderness along the treated lines, mild swelling and an occasional patch of numbness or tingling can persist for a time, and small bruises are possible. None of these need treatment beyond time.

What warrants review. A welt or ridge that does not flatten, or a white line, blister or crust on the surface. New weakness of a facial muscle, such as an uneven smile or difficulty raising a brow, or numbness that is not improving. These are uncommon and are reviewed promptly rather than watched.

The risks. Surface burns are rare but possible if coupling is poor or the focus is too superficial for the skin. Nerve irritation, usually of the marginal mandibular branch along the jaw or the temporal branch above the brow, can cause temporary weakness. Fat atrophy is the risk most specific to focused ultrasound: heat placed into fat rather than the SMAS, or over-treatment of a thin face, can cause volume loss that reads as hollowing. That is why Dr Sin Yong does not use Ultherapy or HIFU on a lean face; the VF Lift – Vertical Facelift is used there instead. How that and Time Freeze lift without filler is compared on VF Lift vs HIFU. Each risk is less likely when the focus is placed under imaging by a physician who knows where the nerves and fat compartments run. More detail is on Ultherapy side effects.

Ultherapy treatment in Singapore: assessment, treatment day and aftercare

1. Before the visit. Declare any pacemaker, implant, metal, threads or fillers, all medicines and skin conditions, and pregnancy or breastfeeding. Avoid sun and tanning beforehand.
2. Assessment. Dr Sin Yong examines the face at rest and in animation, pinches and lifts the skin to gauge its recoil, and separates laxity from volume loss and fat. If Ultherapy is not the right mechanism, he says so; that is a common outcome of the appointment.
3. Planning the map. Lines are planned zone by zone: which depths, how many lines and in which direction, adjusted on the day to what the imaging shows.
4. Preparation. The skin is cleansed and the zones marked. Analgesia is discussed and provided according to the areas and your tolerance; the 4.5 mm lines are felt most.
5. Imaging and delivery. For each line the DeepSEE image is checked to confirm the target layer and full contact, then the line is delivered. Sensations range from warmth to a brief deep ache, most noticeable over bone and along the jaw.
6. Afterwards. The skin may be flushed and slightly swollen. Ordinary activities, make-up and skincare can resume, with sun protection as usual.
7. Review. The response is reviewed as collagen remodelling continues, rather than judged on the day; how results build over time is described on HIFU results.

The checklist is on Ultherapy aftercare, and the visit is walked through on what a HIFU visit involves.

How Dr Sin Yong approaches Ultherapy

Dr Sin Yong performs Ultherapy Prime himself and checks the DeepSEE image before each line, so the depth for each zone is confirmed rather than assumed. He is also invited by CLASSYS, the maker of the Ultraformer MPT, to share his clinical expertise internationally, so the comparison comes from a physician who uses both.

“Lifting tissue that has lost volume does not replace the volume. Ultrasound can tighten what is there; it cannot put back what has gone.”

Dr Sin YongOn laxity versus volume loss

He sometimes plans Ultherapy alone, sometimes alongside another mechanism, and sometimes not at all. Because he also performs the Ultraformer MPT, Thermage FLX, the VF Lift – Vertical Facelift and the Bliss Lift, the recommendation follows the anatomy rather than the device in the room. When Ultherapy is not suitable, that is said plainly, and the written plan states which mechanism was chosen and why the others were set aside. Suitability is decided in person, never from a photograph.
