CoolSculpting vs SKINSHAPE fat freezing, microwave and ultrasound contouring compared

The names

CoolSculpting, cryolipolysis and fat freezing: what the names mean

Cryolipolysis is the medical name for reducing fat with controlled cooling. Fat freezing is the everyday name for the same thing. CoolSculpting is one brand of cryolipolysis device; other brands use the same principle with different applicators and settings. When people search for CoolSculpting in Singapore, they are usually looking for fat freezing in general.

In Singapore, cryolipolysis is offered at doctors' clinics. IN Eternity Clinic, our affiliated medical clinic at Pacific Plaza, offers fat freezing (cryolipolysis) performed by Dr Sin Yong; it does not offer the CoolSculpting brand. SkinRev Lab, a non-invasive aesthetic centre at CityLink Mall, does not offer fat freezing of any kind. Its body contouring options are SKINSHAPE (microwave) and SKINUSHAPE (guided ultrasound).

Side by side

Fat freezing, SKINSHAPE and SKINUSHAPE compared

All three aim to reduce a localised layer of fat under the skin. They differ in the energy used, how the session feels and what else they act on. Figures for fat freezing are typical published ranges and vary with the device and applicator.

Sessions

How many sessions, and when you see a change

With fat freezing, each area is treated with one or more applicator cycles. The injured fat cells are cleared gradually, so the change is not visible on the day; it usually develops over two to three months, and a review appointment decides whether a further cycle makes sense.

SKINSHAPE and SKINUSHAPE are planned as a course. Each 15 × 15 cm zone is treated per session, sessions are spaced a few weeks apart, and results build across the course as the body clears treated fat. A full abdomen is usually two zones. The number of sessions depends on the area, the depth of the fat and your goal, and is set out at your assessment before you book.

Whichever route you choose, the fat cells that remain in an area can still enlarge if weight goes up, so a stable weight helps keep the contour.

Safety

Paradoxical adipose hyperplasia: the rare risk with fat freezing

Paradoxical adipose hyperplasia (PAH) is a rare complication in which the treated area slowly becomes larger and firmer weeks to months after cryolipolysis, instead of smaller. A 2025 systematic review and meta-analysis of 28 studies and 13,078 patients estimated it at 0.22%, about 1 in 455 people. The authors rated the evidence as low certainty, noted that only a few studies followed people for 16 weeks or longer, and concluded the rate appears higher than manufacturer reports.

PAH does not go away on its own and usually needs surgical correction, such as liposuction. That is why it should be explained before treatment, and why a growing, firm area weeks after fat freezing should be reported to the treating doctor early.

Fat freezing is also not suitable for people with cold-triggered conditions such as cryoglobulinaemia, cold urticaria or paroxysmal cold haemoglobinuria, during pregnancy, or over a hernia or recent surgery in the area. These are checked at a medical consultation.

Who suits which

Which approach suits which kind of stubborn fat

• A distinct, soft, pinchable bulge that fits an applicator, and you are comfortable with cold and a doctor-led process: fat freezing at IN Eternity Clinic.
• Fat with some loose skin or cellulite on the same area, and you prefer warmth to cold: SKINSHAPE at SkinRev Lab.
• Deeper or more compact fat that has been slow to change: SKINUSHAPE at SkinRev Lab.
• Fat, cellulite and laxity overlapping, or medical factors to check: a doctor's assessment, where Onda Pro (DEKA Coolwaves microwave) is one option at IN Eternity Clinic.
• Heavy, overhanging skin or a wide muscle separation: a surgical opinion, as none of these treatments removes excess skin.
• Weight is the main goal: start with doctor-supervised weight management, and consider contouring once weight is stable.

Evidence

What the research shows, honestly

Cryolipolysis has the largest evidence base of the three. The original 2008 study showed that controlled cooling could injure fat selectively without damaging the skin, and a 2015 systematic review of 19 clinical studies found average reductions in treated fat thickness of roughly 15% to 29% on calliper measurement, with mild, short-term side effects in most people.

Microwave contouring has a smaller literature, mostly small studies on one brand's system. In one retrospective study of 20 people treated on the abdomen with four sessions, three-dimensional imaging showed lower abdominal circumference and volume three months later; one author worked for the device maker, and there was no control group. We did not find peer-reviewed studies of the specific Miglou system SKINSHAPE uses, so its details rely on manufacturer documentation.

A broader review of non-invasive contouring describes the effects as mild to moderate, for example 2 to 4 cm of circumference over a course, and found no definitive non-invasive treatment for cellulite. Results vary between people, and none of these treatments replaces weight management.

Prices

What fat freezing and contouring cost in Singapore

In October 2026, publicly listed prices for CoolSculpting in central Singapore started at about S$400, with listings ranging up to about S$5,500. Most listings did not say whether the price was per cycle, per area or per package, so ask exactly what a quote covers before comparing.

At SkinRev Lab, SKINSHAPE and SKINUSHAPE are S$288 per 15 × 15 cm zone per session before GST, with one first-visit zone at S$88. Your Aesthetic Specialist maps the zones and sets out the total before you book. Fat freezing and Onda Pro at IN Eternity Clinic are priced at consultation by the clinic, after Dr Sin Yong has assessed the area.

SkinRev Lab is at CityLink Mall #B1-28, 1 Raffles Link, linked underground to City Hall and Esplanade MRT, open daily 11am to 8pm; WhatsApp +65 8266 9585. IN Eternity Clinic is at 9 Scotts Road, #12-01 Pacific Plaza, beside Orchard MRT; WhatsApp +65 8815 3008.
