Ultimate Guide to Vaser Liposuction

Vaser Liposuction is also known as Vaser-assisted liposuction, or Vaser Liposelection.

Vaser is a liposuction procedure that uses high-frequency sound waves (ultrasound) to break up fat deposits before the fats are physically sucked out. This loosens up the fat pockets, which in turn reduces the effort to extract the fat cells. So what we can achieve with Vaser Liposuction is an effective liposuction (ie. large areas can be treated with less surgeon exhaustion), potentially less skin unevenness, and with generally less trauma.


It is worth noting here that the best liposuction results depend on the the skill and experience of surgeon, and not so much on “what tools he uses”. Vaser Liposuction, Vaser HD or even other techniques of liposuction are not a weight reduction tools. Liposuction is a body-sculpting and contouring treatment that is best suited for small areas of disproportion like the saddle bags, the abdomen and love-handles or the breasts in men.



The Steps in a Vaser Liposuction Procedure

  1. The first step during Vaser Liposuction is tumescent anaesthesia. This anaesthetic solution is infused into the fat layer just under the skin to “distend” it. The distended fat layer makes it easier to move the suction cannula through it. It also reduces bleeding and provides greater comfort after the whole liposuction procedure.
  2. The next step involves the use of an ultrasonic probe which is inserted into the fat layer to loosen up the fat. This step is particularly useful in areas where the fat is dense (tough) or if there is a lot of adhesions from previous liposuction or even with Paroxysmal Adipose Hyperplasia (PAH) following Coolsculpting.
  3. Then the suction. The end point of “suction” in any liposuction is deemed to have been reached when the curves flow smoothly and harmoniously. In Vaser HD (high-def Vaser), special cannulas are used to sculpt muscle shapes out of fat deposits.
  4. The recovery time depends on the extent of the areas treated. For the thighs, most of our vaser liposuction patients are up and about the next day. Bed rest is not necessary, but their movements might be a little slower because of the soreness. They might even be back in the gym the following week.

Where is Vaser Liposuction done?


The Vaser liposuction procedure is performed in a Day Surgery OT with and anaesthetist. The amount that can be treated in a session really actually depends on the safe amounts of tumescent anaesthesia that can be injected in a session. And this is calculated based on the weight of the person.

What is Vaser HD?


Vaser HD means we sculpt the patient’s layer of fat into muscle shapes. Or else we can also suck nearer to the skin so that the muscle shapes beneath are revealed.
