Vaser liposuction is a minimally invasive fat removal procedure used to optimize the removal of unwanted fat from all parts of the body and even the under chin area. It uses innovative ultrasound technology to to break down unwanted fat before it is removed by traditional liposuction methods. The ultrasound technology allows for easier breakdown of fat which translates into a smoother recovery with less pain and bruising.

What is Vaser-Assisted Liposuction?

Vaser-assisted liposuction (VAL) is a very specialized, type of liposuction that utilizes state-of-the-art ultrasound technology to enhance the removal of unwanted fat from the body. Vaser is an acronym for “ vibration amplification of sound energy at resonance “.

Vaser liposuction is a minimally invasive procedure that is incorporated into traditional liposuction, through the same incisions used to remove the fat. The Vaser liposuction technology works by selectively targeting and breaking down fat cells through a process known as acoustic streaming, allowing for easier and more predictable removal of the unwanted fat.

The procedure takes as little as a few minutes to as much as an hour, depending on the number of areas being treated on the body, the amount of fat being removed, and the degree of contouring that the patient is seeking. Once the fat is broken down by the Vaser technology, it easily is removed by traditional or power-assisted liposuction, creating a much-improved contour, with less pain, bruising, and tighter skin.

Vaser liposuction is commonly used in revision liposuction procedures because it is able to create very smooth tissue planes, eliminating and correcting dents and asymmetries left from previous liposuction procedures.

Vaser liposuction is considered the gold standard treatment for 4D high-definition liposuction due to its superior body contouring capabilities.

How the Procedure Works

Vaser liposuction procedures may be performed in-office or at an accredited surgery center, depending on the size and number of areas being treated. Procedures performed under a general anesthetic require a pre-op work up which includes labs, medical clearance, and and ECG when indicated.

Vaser liposuction is a safe and highly effective minimally invasive fat removal treatment that offers several advantages over conventional liposuction. It is a one-of-a-kind permanent solution for the management of unwanted fat deposits and provides unparalleled results in offering 4D high definition body contouring.

Before & Preparation

During your consultation, Dr. Vallecillos will determine if Vaser liposuction is right for you. Treatment goals will be discussed and reasonable expectations will be set. Additionally, Doctor Vallecillos will take a full medical history, including medications and previous surgical procedures. This is also the time to ask any procedural questions you may have. Lastly, pre-and postoperative instructions will be reviewed in preparation for your surgery.

Vaser liposuction does not require extensive preparation. However, there are actions you can take to decrease the risk of bleeding and bruising, and improve your recovery

  • Avoid anti-inflammatory drugs including aspirin and ibuprofen for two weeks prior to the procedure.
  • Avoid alcohol and caffeine 24 hours before the procedure.
  • Stop smoking 2 weeks before the procedure.
  • Avoid certain supplements such as tumeric, ginger, vitamin E, garlic, CoQ10, and ginkgo biloba two weeks prior to the procedure.
  • Increase hydration prior to the procedure.

During the Procedure

  • Anesthesia: Vaser liposuction is typically performed under a general anesthetic for larger cases, although smaller cases may be performed under a local anesthetic with sedation.
  • Duration: 1 hour and up
  • Target Areas: Abdomen, arms, back, calves, flanks, hips, thighs, and submentum
  • Device: Vaser ultrasonic amplifier with modifiable probe lengths and sizes
  • Pain: Well controlled with oral analgesia

Step-by-step guide:

  • Anesthesia is provided either as a general anesthetic or with sedation
  • Tumescent fluid ( local anesthetic ) is injected into the areas of interest and the numbing agent is allowed to take effect for 20 minutes. Blood vessels also shrink during this process which reduces bruising.
  • Next, through small well-hidden incisions, the Vaser ultrasonic amplifier is passed radially through the treatment areas, transmitting sound waves that disrupt fat cells, without harming surrounding tissue, until endpoints are reached ( time and/or amount of resistance ).
  • Once the tissue is Vasered, the fat is easily removed through the same incision via either traditional or power-assisted liposuction ( PAL ).
  • Additional contouring is performed depending on the patient’s goals and desires ( from conventional contouring to high-definition contouring ) with the result being improved muscle definition
  • The result is a substantial improvement in contour with permanently removed fat and a smooth appearance. Once healed, the overlying skin will be noticeably tighter. This may take several months to appreciate
  • Lastly, a specialized compression garment is applied to assist with swelling and body contouring. The garment is worn for 6 weeks in most instances


Tumescent Infusion: Tumescent fluid (numbing fluid) is infused throughout targeted fat tissue. Tight junctions between cells within blood vessel walls and connective tissues prevent gas bubbles from interspersing among and affecting these tissues.


Cavitation: Acoustic energy which is generated through the Vaser device and delivered through the ultrasonic probe results in rapid formation and collapse of bubbles in the tumescent fluid. This dislodges clusters of intact fat cells with minimal (if any) impact on the surrounding tissue ( blood vessels, nerves, muscle).

Acoustic Streaming: Grooves found on the ultrasonic probe generate strong localized fluid forces, further separating dislodged fat clusters into smaller clumps. These smaller clumps of fat can later be used for fat grafting, where indicated.


Fat Removal: The specially designed small-diameter cannulas minimizes trauma to vessels, nerves and the fibrous tissue matrix when inserted to suction out the mixed fat cell and tumescent fluid emulsion.


Retraction: The heat imparted on the fibrous network connecting the muscle to the overlying skin results in super skin retraction ( tightening ) as compared to conventional liposuction.

Tissue Remodeling: The removal of adipose tissue during liposuction creates a space for optimal retraction to occur.

Aftercare & Recovery

  • Downtime: 5-10 days
  • Common side effects: Swelling, mild bruising
  • Duration of side effects: Majority of swelling gone at 2 weeks. All swelling is gone by 4 months.
  • Ultrasound and lymphatic massage are commenced on post-operative day #1 to expedite the removal of excess fluid.
    Hyperbaric oxygen is recommended for a reduction in inflammation.
  • Avoid heavy exercise for one month.
  • Avoid swimming in the pool, hot tub, lake, or ocean for no less than two weeks.

Revision Liposuction with Vaser Assistance

Skin depressions, “ dents”, and soft-tissue asymmetries are an all too common side-effect of liposuction. Correction with traditional liposuction methods is less than ideal because the technology employed in removing fat does not have the capability to adequately correct soft tissue asymmetries. Before we get into how vaser liposuction can assist in correcting skin depressions, let’s first take a look at the skin architecture.

As seen in the photograph above, there exist two discrete fat layers under the skin separated by a fibrous layer known as fascia. Traditional liposuction is generally performed in the deeper fat layer which lies in a loose areolar plane which is largely devoid of a structured fibrous network, thus making the fat very easy to extract through liposuction. This is converse to the superficial fat, which lies within a complex fibrous network of retaining ligaments, making it very difficult to extract with conventional liposuction techniques.

Contour deformities secondary to traditional liposuction are typically due to the following reasons:

  • Lack of experience in liposuction by the practitioner
  • Overzealous attempt to remove superficial fat pads with traditional liposuction methods

Vaser liposuction provides a means to successfully address fat both in the superficial and deep planes due to its ability to emulsify fat, making it much easier to extract than traditional liposuction. The result is a comprehensive volume reduction of superficial and deep fat planes, with the added ability to create enhanced contour definition.

Additionally, if the patient has mild to modest skin redundancy and/or soft-tissue laxity in the areas being treated with Vaser liposuction, additional procedures such as Renuvion J Plasma and Bodytite can be introduced to optimize the skin tightening.

If you feel you have developed contour deformities due to sub-optimal liposuction results, contact the offices of Doctor Vallecillos to see if Vaser liposuction can be used as a corrective measure.

Frequently Asked Questions

Are there risks or side effects associated with VASER Hi Def Liposculpturing?

Patients experience scarring due to the incisions for the procedure. However, your surgeon attempts to hide these incisions within the body’s natural contours to reduce the appearance of scars.

Other possible side effects include numbness, inflammation, pain, and seroma.

How long do the results last?

Results take around six months to manifest fully. Barring weight gain, results are permanent.

Who is a candidate for VASER Hi Def Liposculpturing?

The ideal candidate enjoys good overall health and is at or near his or her ideal body weight. VASERlipo is intended to bring definition to stubborn fat deposits unaffected by diet and exercise.
