Vaser Liposuction - What is it and how does it work?

We all wish to look our best – and a healthy diet and exercise are, too often, not enough to achieve and maintain our best body. Even at our ideal weight, we can still carry unsightly bulges. VASER liposuction is one option people have been turning to, but there are some important differences between VASER liposuction, regular liposuction and liposculpture.

Liposuction is a cosmetic surgery treatment that has been used for many years to remove fat deposits from beneath the skin and affect a better cosmetic result. It is the most-performed cosmetic surgery procedure worldwide. Over time, there have been significant developments and the technique has been fine-tuned. 

One of these modern developments includes the advent of liposculpture for better results for people who only have mild to moderate amounts of fat to be removed or reshaped. 

Another development is VASER liposuction.

It’s important to understand your options and choose the right fat removal approach for your body, your health, your budget, and your goals.

What is VASER Liposuction?

VASER is an acronym for Vibration Amplification of Sound Energy at Resonance. It is a type of ultrasound technology.

VASER liposuction works by using powerful ultrasonic waves to interrupt the bonds between fat cells. It’s a fat pre-treatment machine. This helps to emulsify or liquefy the fat before it is aspirated. This allows the fat to more easily be shifted and removed during the liposuction procedure. Furthermore, the ultrasound may stimulate collagen production to help tighten the skin.

As with traditional liposuction, VASER liposuction must be performed by an experienced, skilled doctor with a speciality in the procedure.

The Procedure:

1. You will be placed under general anaesthesia or it may be done under light sedation. But abdominal contouring with VASER is often done under general anaesthetic because of the sensitivity of this area. 

2. The treatment area is injected with saline or a tumescent fluid solution.

3. Incisions will be made in the target area and incisions are larger than micro-cannulas liposculpture because plastic protective ports will be placed in the skin to protect against heat from VASER. 

4. Ultrasound probes (4-5mm) are inserted into these small incisions.

5. As the fatty tissues are broken apart by the ultrasound probes, a cannula attached to a vacuum system is used to remove the fat and the majority of the fluid from the same incision.

6. Any remaining fluid (left intentionally to help alleviate pain after the procedure) will be reabsorbed and eliminated by the body over several days.

Limitations, Benefits, and Risks of VASER Liposuction

Liposuction is not a tool for weight loss, but rather for the removal of stubborn pockets of fat in people who are at or close to their ideal weight. It works as a spot treatment and is an effective way to reveal underlying muscle tone. 

VASER technology interrupts the connections between fatty tissues and muscles and does not harm the healthy underlying tissues. It achieves much better body sculpting results than the traditional liposuction technique. 

Like for traditional liposuction, to qualify as a good candidate for VASER liposuction, you should:

  • Be generally healthy
  • Be within about 5-7 kilograms of your ideal weight
  • Not smoke cigarettes
  • Not consume alcohol heavily
  • Not have a history of a bleeding condition

VASER liposuction techniques are suitable for treating:

  • Stomach and waist
  • Buttocks
  • Thighs
  • Hips
  • Upper back
  • Chest
  • Arms
  • Neck and under the chin

As with any cosmetic procedure, there are some risks with VASER liposuction:

  • Bleeding/bruising
  • Pain
  • Persistent swelling
  • Skin irregularities, asymmetry, and hyperpigmentation over the treatment area
  • Scarring 
  • Loose skin long term
  • Rarely, an infection may occur – be alert to signs such as fever, shortness of breath, dizziness, nausea, vomiting, purulent discharge from the incisions, or generally feeling unwell. 

VASER Liposuction vs Traditional Liposuction

Traditional liposuction uses water pressure and laser technology to break the bonds within fat deposits in the body and remove them using a combination of anaesthetic, saline solution, and cannulas. 

Like lasers and water pressure techniques, VASER pulsed ultrasonic waves generate heat which breaks the fat cells apart. This makes them significantly easier to remove through cannulas inserted into the area being treated.

VASER liposuction is a more precise, gentler approach to liposuction.

Compared with traditional laser liposuction, VASER is:

  • Less invasive
  • Less painful
  • More effective over a larger area
  • Emulsifies fat for optional use in fat transfer procedures
  • May encourage skin tightening

Vaser Liposcution vs Liposculpture

Like liposculpture, VASER liposuction can achieve a good contouring result. It is, however, not as fine-tuned and is a much more invasive procedure than liposculpture and has higher risk of burns or cavitation (areas of fluid build-up that may require drainage) and often requires general anaesthesia. 

Liposculpture is an extremely refined technique that uses microcannulas to remove small to moderate fat deposits. It uses tumescent anaesthesia – this is a local anaesthetic that includes adrenaline (epinephrine) in its solution. Injected into fatty deposits, the solution fills the area and causes it to swell and become firm. This enables the liposculpture proceduralist better control to sculpt and contour the area.

Unlike traditional or VASER liposuction, a person undergoing liposculpture stays awake and does not need to be admitted to hospital. Mild sedation is available however. Microcannular liposculpture results in less pain, more accuracy, greater finesse, effective superficial liposculpture, more complete removal of fat, easier penetration, smaller incisions, no sutures, accelerated healing and greater efficiency. Time efficiency is important. The goal of any liposculpture technique is not how fast the fat is removed, but how completely fat is removed. The extra time needed to use microcannulae is actually more time efficient as there is often a lower incidence of any secondary “touch-up” procedures.  If a proceduralist doesn’t have enough time to do it right the first time, when will he or she have time to do it right a second time!! Allowing enough time to do the procedures is of utmost importance. 

Tumescent liposculpture at Be Sculptured benefits patients most when compared with traditional and VASER liposuction.


  • Causes less pain
  • Results in no visible scarring(as there are no sutures)
  • Lower infection risk
  • Can remove more fat and from smaller areas
  • Little downtime mostly 
  • Faster recovery time
  • Elicits better cosmetic outcomes
  • Costs less than liposuction

Book for Liposculpture at Be Sculptured

Be Sculptured is open as usual for liposculpture procedures. We comply with all current NSW Health COVID protocols.

VASER liposuction is a better alternative to traditional liposuction for many patients. The gold standard, however, for those who are suitable for it, is tumescent liposculpture – which we offer in our Be Sculptured Crows Nest Clinic.
