Body Lifting: Abdomen, Thighs and Arms
Three devices, set for the body rather than the face. Each destroys fat cells and tightens the skin above them, and which one you get depends on whether your concern is the fat, the skin, or both.
Not liposuction, and not a replacement for it. These treat a moderate amount of fat where skin tone also matters and you cannot take weeks away from normal life. If what you need is a large reduction, we will tell you plainly that surgery is the honest answer.

Quick Answer
What does body lifting actually do?
Two things at once: fewer fat cells, firmer skin over them.
In Brief
Energy devices that reduce fat and firm the skin above it.
Energy applied through the skin destroys fat cells underneath while tightening the skin above them in the same session. That combination is the point: reducing fat alone can leave skin looser than it started, which is the usual complaint after a large reduction. Destroyed fat cells do not come back, but the ones that remain can still enlarge, so the result holds only alongside the rest of how you live.

Side by Side
Against Injections and Surgery
Three ways to reduce body fat, and they aren’t interchangeable.
| Fat-dissolving injection | Liposuction | Body lifting | |
|---|---|---|---|
| How it works | Medication breaks down fat | Fat removed surgically through an incision | Energy destroys fat cells and tightens skin |
| Method | Injection | Incision and cannula | Non-invasive, applied to the skin surface |
| Anaesthetic | Topical | General or local, required | Usually none |
| Downtime | Bruising and swelling, 3-5 days | One to three months | Almost none |
| Skin afterwards | Fat reduces; skin may stay loose | Largest reduction, but skin can sag | Tightens as the fat reduces |
| Scale of change | Modest, varies by person | Large | Moderate, across a course |
These are not ranked. Liposuction removes far more fat than any energy device, and if that’s what you need, an energy treatment will disappoint you. Body lifting suits a moderate amount of fat where skin tone also matters, and where you can’t take weeks away from normal life.
Understanding It
Three Energies, Three Different Jobs
The three devices here are not interchangeable, and they do not work the same way. Focused ultrasound reaches a fixed depth and deposits energy at a precise point, which is what makes it predictable for fat held at a known layer. Microwave heats a broad volume of tissue rather than a point. Radiofrequency with high-voltage pulses works on fat while vacuum draws the tissue to the applicator. Same goal, three different physics.
Which one suits you is decided by what is actually there. Where a defined pad of fat sits at a consistent depth — the lower abdomen, flanks — focused ultrasound is the straightforward answer. Where the fat is more diffuse and the skin above it has also lost tone, the radiofrequency approach addresses both in one pass. Where the skin is the dominant complaint and the fat is secondary, the settings change again.
Body areas also behave differently from the face, which is why the same devices are run at different settings here. There is more tissue, it moves more, and it takes more sessions to show a change. Three is the usual minimum, three to four weeks apart, and the result is assessed across the course rather than after the first visit.

Candidacy
Who It May Be For
It suits people carrying a moderate amount of fat in a defined area — lower abdomen, flanks, outer thighs, the bra line — where the skin above it has also lost some tone. Treating the fat alone in that situation often leaves the skin looser than it started.
It also suits people who cannot take weeks away from normal life. There is usually no anaesthetic and almost no downtime, which is the practical trade-off against a surgical reduction.
It suits less well where the amount of fat is large. No energy device removes what liposuction removes, and spending across a course of sessions to reach a result that was never achievable is the most common way money gets wasted here. If that is your situation we will say so at consultation.
The Visit
What to Expect
The area is cleansed and mapped, and a gel or coupling medium applied depending on the device. Most body treatments need no anaesthetic; where one is used it is topical and left to take effect first.
The system monitors skin temperature up to a thousand times a second and cuts power if the surface reaches its set limit. Treatment runs at a target tissue temperature of roughly 41-43°C. That is a meaningful safety feature rather than marketing, and it is part of why the treatment is well tolerated.
Expect warmth during treatment and some redness afterwards, usually settling within a day. Body areas can feel tender to the touch for a few days. There is no dressing and nothing to keep out of the sun.
A Note
What We’ll Tell You First
Fat reduction by energy is gradual and partial by nature. Destroyed fat cells do not regenerate, but the cells left behind can still enlarge, so the result holds alongside the rest of how you live rather than independently of it.
At consultation we will tell you which of the three devices is being proposed, why that one, and what it does not do. If the honest answer is that the amount of fat calls for surgery, or that the skin needs addressing before the fat, you will hear that first rather than after a course of sessions.
Honest Alternatives
If Something Else Fits Better
Balance
A smaller, more targeted reduction where a defined pocket is the whole concern.
Lifting
Non-fractional radiofrequency across the surface, where firmness is the whole concern.
Key Points
What to Take Away
- Three devices at body settings: Ultline 13mm, Onda microwave, InMode RF.
- They destroy fat cells and tighten skin in the same session.
- Abdomen, love handles, thighs, buttocks, forearms, bra line.
- Destroyed fat cells do not return, but the rest can still enlarge.
- Three or more sessions, three to four weeks apart.
- Usually no anaesthetic, almost no downtime.
- Not liposuction. If you need a large reduction, we will say so.
FAQ
Questions People Ask
It is designed for localised fat in a specific area — the lower abdomen, the flanks, the bra line — rather than overall weight. If the area is small and stubborn, it suits you. If you’re looking for a large reduction, liposuction removes far more and we’ll say so.
Destroyed fat cells do not regenerate. The cells that remain can still enlarge with weight gain, so this is not a substitute for managing your weight.
Most people feel warmth building rather than pain, and no anaesthetic is usually needed. Tell us if it becomes uncomfortable and the intensity is reduced.
Onlif recommends three or more, spaced three to four weeks apart. The number depends on the area and how much fat is there.
Almost none. You can return to normal activity the same day.
An injection reduces fat but can leave the skin loose. These devices tighten as the fat reduces, which is the main argument for them. The two can also be combined — the injection helps clear the broken-down fat.
Ultline’s 13mm cartridge for thick abdominal fat, Onda for cellulite on thighs and buttocks, InMode for forearms, accessory breast and the bra line. Your doctor chooses by where the fat sits and how much elasticity has been lost.

At Onlif
The Three Devices We Use
Body Ultline
Focused ultrasound at 13mm, deeper than the facial cartridges. It deposits energy at a fixed, predictable depth, which suits a defined pad of fat sitting at a consistent layer — the lower abdomen and flanks are the usual areas.
Body Onda
Microwave at 2.45GHz. Rather than depositing energy at a single point, it heats a broader volume of tissue, which suits fat that is diffuse rather than concentrated.
Body InMode
Radiofrequency with high-voltage pulses, with vacuum drawing the tissue to the applicator. It works on the fat and the skin above it in the same pass, which is why it is chosen where laxity is part of the complaint.
The device is chosen by what is actually causing the change: fat, skin quality, or both. Temperature is monitored continuously during treatment, which keeps it comfortable and reduces the risk of burns.
