Key takeaways

  • Liposuction is surgery: it is usually done under general anaesthesia, you wear a compression garment for several weeks, and swelling can take up to 6 months to settle.
  • It is designed to remove fat in one operation, but it is not a treatment for obesity and does not remove cellulite or stretch marks.
  • SLIM Body is non-invasive and painless: 45 minutes, zero downtime, with your result measured before you leave.

Liposuction is surgery: fat is removed through small incisions, usually under anaesthesia, and the area needs weeks to months to settle. Non-surgical body contouring such as SLIM Body works without incisions or anaesthesia, takes 45 minutes and has zero downtime. Which one fits depends on how much you want to change, and how much recovery you can plan around. (Source: NHS (opens in a new tab))

What liposuction is

The NHS describes liposuction as a cosmetic procedure used to remove unwanted body fat (opens in a new tab). The surgeon loosens the fat, for example with high-frequency vibrations, a weak laser pulse or a high-pressure water jet, and then suctions it out through a thin tube. VASER liposuction (opens in a new tab) is a form of ultrasound-assisted liposuction. It is still liposuction, with an operation, anaesthesia and recovery.

Anaesthesia and hospital stay

According to the NHS, liposuction is usually carried out under general anaesthesia, and most people stay in hospital overnight. Cleveland Clinic (opens in a new tab) notes that smaller areas may be treated under local anaesthesia, and that many procedures are done as outpatient surgery, so you go home the same day. How it is done in your case is for the surgeon to explain.

Recovery

After the operation you wear a compression garment, which the NHS says should be worn constantly for several weeks. Bruising and swelling may last up to 6 months, and it can take up to 6 months for the area to settle completely. Cleveland Clinic writes that most people can return to work within a few days and to normal activities within about two weeks.

Risks

Like any operation, liposuction carries a small risk of excessive bleeding, blood clots, infection and an allergic reaction to the anaesthetic (NHS (opens in a new tab)). The NHS also advises researching the surgeon who will carry out the operation and thinking very carefully before you go ahead.

When you see the result

The result is not always noticeable until the swelling has gone down. The NHS describes the results as generally long-lasting, provided you maintain a healthy weight.

What liposuction is better suited for

Liposuction takes fat out of the body in one procedure. In an analysis reported by the American Society of Plastic Surgeons (opens in a new tab), the average volume removed was about 2 litres, and procedures above 5 litres count as large-volume liposuction. If you want a large change in fat volume in one go, and you are ready for surgery, anaesthesia and the recovery that comes with it, that is what liposuction is designed for.

What it is not designed for matters just as much. The NHS states that liposuction is not a treatment for obesity and will not remove cellulite or stretch marks, and that it works best in people who are not overweight and in areas where the skin is firm and elastic. Cleveland Clinic adds that it is not an alternative to weight loss. (Sources: NHS (opens in a new tab); Cleveland Clinic (opens in a new tab))

What SLIM Body does differently

SLIM Body is non-invasive and painless. There is no incision, no anaesthesia and no hospital stay, so you can go straight back to your day. One session takes 45 minutes on the treatment bed.

  • Fat: your fat cells open and shrink. The released fat is processed naturally by your body over the next 24–48 hours.
  • Muscles: gentle pulses activate your muscles in the same session, like a workout, without the workout.
  • Skin: SLIM Body supports skin tightening.
  • Measured, not estimated: your trial starts with a BIA body analysis and measurements at 2–3 areas. We measure again before you leave, so you see the change in centimetres on the same day.

SLIM Body uses certified European technology: six technologies, one session.

How to decide

Ask yourself three questions. How much do you want to change? Can you take time out for surgery and recovery? And do you want to see a measured result on the same day? If your goal is a large volume of fat in one operation, talk to a surgeon about liposuction. If you want centimetres off 2–3 areas, firmer-looking skin and no downtime, a SLIM Body trial is a simple way to find out what your body responds to.

Where SLIM fits

SLIM Body is not surgery and does not try to be. It is for people who want a visible, measurable change on the areas that bother them (belly, waist, thighs or arms) without anaesthesia, incisions or recovery time. You lie on the treatment bed for 45 minutes, your therapist adjusts the session to your body, and you leave with your before-and-after measurements.
