Liposuction - Vaser

‘VASER’ stands for Vibration Amplification of Sound Energy at Resonance which uses advanced ultrasound technology to gently breakdown fat from different areas of the body.

The technique uses sound energy transmitted through small probes that liquefy fat prior to removal by gentle suction. In conventional liposuction, an incision is made in your skin to allow a vacuum pump or syringe to be inserted. This is moved within the fatty tissue to suck out the fat and fluid. This contrasts with VASER lipo, where the ultrasound energy is directed specifically at the fat to liquefy it prior to removal by gentle suction.

During the procedure:

The anaesthetic: If small volumes of fat are to be removed, then VASER® has the advantage in that usually a local anaesthetic is all that is required and this means that you are awake during the procedure. For larger volumes of fat removal or if multiple areas are treated, sedation or a full general anaesthetic may be required.

The procedure: During the procedure, the surgeon will make small incisions typically four to five mm long and inject fluid which is absorbed by the fat. An ultrasound probe is then introduced under the skin.  These probes are blunt and pass through the fat easily. There are different types of probes depending on the area of the body and the quality of skin overlying the fat. The probe disperses the ultrasound energy into the surrounding fat to emulsify it.  A different suction cannula is the introduced under the skin to remove the liquefied fat. Once the treatment is complete either a small dissolvable stitch or a dressing is applied to the entry points.

After the procedure:

For small to intermediate volumes of fat removal, you will usually be able to go home the same day. For large volumes of fat removal you will be required to stay the night in hospital.

You will need to wear a compression garment; for a period of one week for very small areas of fat removal or up to six weeks for larger areas. This garment will be provided for you.

One of the benefits of VASER is that pain and discomfort is reduced compared to conventional liposuction. However, painkillers are prescribed for you in case you need them. Significant bruising is unlikely but should any mild bruising occur this should resolve quickly, within one to two weeks.

For small to intermediate volume fat removal you should be able to return to work within a few days but if large volumes of fat are removed you may require up to one week off work.

Strenuous exercise should be avoided for at least two weeks after the procedure. There will be some swelling after the procedure and it is important to allow the tissues to fully heal before engaging in heavy exercise. If multiple areas and large amounts of fat are removed your surgeon may recommend to avoid exercise for a longer period of time.

You may notice an immediate change after the surgery however any swelling will take about a week to improve. The soft tissues and skin do take time to retract. Even though VASER liposuction allows improved skin retraction it can still take three to six months to see the full benefits and results of this technique.

VASER liposelection for specific body areas:

VASER liposelection can be used on any part of the body including the face and neck, male chest, abdomen, buttocks, arms, back or thighs.


Each form of liposuction carries its own risks and limitations, and your consultant will discuss these thoroughly with you in your consultation. It's essential to have realistic goals and to discuss all of the surgical options available in order to find the correct treatment for your individual needs.
