What HIFU is
HIFU stands for high-intensity focused ultrasound. The beam passes through the skin and converges on tiny points below it. Heat is aimed at these points rather than at the surface. Over time the tissue remodels and new collagen forms. Nothing is cut and no dressing is needed.
This guide explains the method in plain terms. It is general information, not a diagnosis. Tissue decides suitability, not age, so the answer for you depends on what an examination finds.
HIFU treatment in Singapore: the short answer
HIFU is meant for early to moderate looseness along the jawline, under the chin and across the neck. The face should have enough tissue and should not have lost much volume. Any change is slow, so nothing should be expected on the day. For the procedure itself, including the devices used here, see the HIFU treatment page. For what happens after a session, read the HIFU downtime page.
Which depth does what
| Cartridge depth | What it targets |
|---|---|
| 4.5 mm | The SMAS, the deeper support layer |
| 3.0 mm | The dermis |
| 2.0 mm | Used mainly over the brow and forehead |
| 1.5 mm | The superficial dermis |
The three platforms
Three devices are used. Ultraformer MPT is micro-pulsed and has no imaging. Its face cartridges come in 1.5, 2.0, 3.0 and 4.5 mm, and separate body cartridges go deeper. Ultherapy Prime has 1.5, 3.0 and 4.5 mm cartridges, with DeepSEE imaging before each line. New Doublo 2.0, made by HIRONIC, pairs focused ultrasound for the SMAS and deep dermis with radiofrequency for the mid-layer and surface. None is ranked above the others. Depth is chosen by feeling the thickness of the tissue, zone by zone. Labels such as 4D, 7D or 12D are the maker's wording. If you are weighing Ultherapy against the others, see Ultherapy vs HIFU.
Who HIFU tends to suit
Three checks help. The looseness is early to moderate. It sits along the jawline, under the chin or across the neck. And the area has enough tissue depth, without marked volume loss or a full fat pad. Age alone does not settle the question. Two people of the same age can have quite different tissue, so one may suit HIFU while the other needs a different plan. The outcome depends on your starting point, the depths chosen and how your tissue responds, so results vary. A 2023 systematic review of micro-focused ultrasound looked at mild to moderate laxity, and results declined as laxity and BMI rose. These are findings across groups. They help set expectations but cannot predict your own response. Checking depth by touch and staying clear of the thyroid and nerve courses lowers risk, yet it does not remove it.
Who should wait, and who should look elsewhere
Pregnancy, active infection, open wounds or inflamed acne in the area, a recent tan, or recent filler or threads in the treatment plane.
Implants or metal in the field, a history of keloid scarring, and blood-thinning medicines.
With little tissue above bone, heat can cause fat loss that reads as hollowing, so HIFU is not planned. Monopolar radiofrequency on the VF Lift is considered instead.
A full double chin or fatty jowl is not a HIFU problem. Heavy, redundant skin or deep jowls go to a plastic surgery specialist.
What HIFU cannot do
Sagging driven by volume loss needs a different plan, one that addresses volume.
It does not take away heavy skin or clear a full fat pad.
Movement lines are driven by muscle, so anti-wrinkle injections are the likelier route.
Colour concerns need a separate assessment.
Risks to discuss first
How a visit runs
What to tell the doctor first
Implants or metal, blood-thinning medicines, keloid scarring and pregnancy.
Any filler or threads in the area, and when they were done.
A recent tan, open wounds, infection or inflamed acne.
Radiofrequency or laser may be part of a plan. Where filler is planned too, HIFU typically comes first and filler follows once inflammation has settled.
How fees are worked out
The fee depends on the zones treated, cartridge depths and number of lines, the device and consumables, any combination with radiofrequency or laser, and the review visit. Shot counts alone cannot be compared across devices. The HIFU cost factors page explains this further.
