VASER liposuction: a guide to VASER lipo

VASER liposuction, or VASER lipo, is ultrasound-assisted liposuction: a cannula vibrates at high frequency, liquefies localised fat and makes it easier to remove. On this Clínica EGOS page we explain who it is considered for, how it is done, what recovery is like and what to ask for in a quote, so that you arrive at your first consultation with your questions answered.

It is worth knowing from the start: liposuction is not a treatment for obesity, and no technology replaces the surgeon's assessment of your skin and your body contour.

When does liposuction make sense?

Liposuction removes localised fat deposits to improve body contour. On its own it does not remove a significant excess of skin, and it is not a substitute for a weight-loss treatment. It can be considered when there is localised fat and an indication confirmed after examining the quality of the skin and the body contour. If laxity or separation of the muscles predominates, a different technique, or one combined with this, may be needed.

The final indication requires an in-person medical assessment. If you are comparing clinics, we have a guide on how to compare body surgery clinics.

What is VASER liposuction?

VASER liposuction is an ultrasound-assisted liposuction technique (UAL). A cannula with a high-frequency vibration breaks up and liquefies the fat, which is then suctioned out more easily. It is used to sculpt the desired area and allows localised work both on large areas, such as the abdomen or legs, and on smaller ones, for example the ankles or submental liposuction.

The aim of the technology is to work on the fat while sparing, as far as possible, other structures such as blood vessels and nerves. According to a review published in 2025 in Aesthetic Plastic Surgery (Atieh and colleagues), third-generation ultrasound liposuction, VASER, is used in approximately 20% of liposuctions. The review describes it as a technique with well-documented clinical efficacy.

The same review points out that long-term data are lacking to confirm better skin retraction or a better aesthetic result than with conventional liposuction. For that reason, it is best not to expect VASER lipo to be a solution for skin laxity: it depends on each case, and the surgeon assesses it at the consultation.

VASER liposuction compared with other techniques

Liposuction is a procedure designed to remove persistent fat deposits that resist diet and exercise. It is performed by plastic surgeons to sculpt areas such as the hips, abdomen, thighs, buttocks, back, arms or the area under the chin, and it can complement other surgeries, such as a facelift, breast reduction or abdominoplasty. There are several liposuction techniques; these are the ones most often mentioned.

Tumescent technique

This is the most common. Before the fat is removed, a generous amount of diluted solution with anaesthetic is infiltrated into the area, which reduces bleeding and makes suction easier, and it is then drawn out together with the fat. It takes longer than other techniques.

Super-wet technique

It is similar to the previous one, but the amount of fluid infiltrated is the same as the amount of fat to be removed. It takes less time to perform.

Laser-assisted technique (LAL)

It uses a laser to liquefy the fat cells, which are then suctioned or drained through cannulas that are finer than those of conventional liposuction. It is used mainly on small areas, such as the chin, the jawline or the face.

Ultrasound-assisted technique (VASER lipo)

It uses ultrasonic vibrations to turn the fat cells into liquid and then suctions them out. It takes longer than the super-wet technique.

VASER liposuction: who it is considered for

Liposuction is suitable for adults of normal weight or slightly overweight who have localised fat deposits. According to the ASPS (American Society of Plastic Surgeons), the specific profile is that of healthy adults whose weight is within 30% of their ideal weight, with firm, elastic skin and good muscle tone, with no condition that hinders healing and with clear contouring goals.

Better results are obtained in areas such as the abdomen, flanks, thighs, arms and back. Ideally, one to three areas are treated; if more are needed, the surgeon may suggest other methods, especially when there is significant excess weight. The ASPS adds that liposuction is a very personal decision made for yourself, and not to fulfil another person's wishes or to fit an ideal image.

When it is worth considering another option

If the skin has lost elasticity, liposuction alone may not give the contour you are looking for. When excess skin predominates, the surgeon may propose an abdominoplasty or other body-contouring surgery instead of, or together with, liposuction.

What a VASER lipo is like, step by step

The consultation and preparation

The surgeon examines the area, the skin and your medical history, listens to what you want to change and explains which technique suits you and why. Tell them everything, even if it does not seem important: you will be asked about your health, your allergies, the medicines and supplements you take, and about alcohol, tobacco and other substances. It is also the moment to ask about the areas that would be treated, the anaesthesia and the follow-up.

Before the operation you are given instructions. According to the ASPS, it is advisable to adjust some medicines and supplements that increase bleeding, to stop smoking because tobacco reduces blood supply and hinders healing, and to arrange for someone to take you to and from the clinic and stay with you for at least the first night after the procedure.

The day of the procedure

The SECPRE points out that liposuction is always performed in an operating theatre, usually under local anaesthesia with sedation, and under general anaesthesia in very extensive cases. At Clínica EGOS, VASER lipo is planned under general anaesthesia and lasts about three hours, which varies with the areas treated. Small incisions are made through which the cannula is inserted, the liquefied fat is suctioned out and the stitches are closed.

Afterwards

When it is finished, the area is covered with dressings and a compression garment or an elastic bandage is fitted, which limit swelling and support the body while it heals, according to the ASPS. We give you the care instructions, the medication and the dates of the check-ups in writing.

The most common areas for VASER liposuction and what is assessed in each

The SECPRE mentions the hips, thighs, knees, ankles, arms, abdomen and face as common areas. In each one the surgeon looks at different things, which is why the examination is in person.

In the abdomen and flanks, besides the fat, the skin and the separation of the muscles are assessed, because if excess skin or laxity predominates, liposuction alone may not be enough.

In the thighs and hips, the proportion of the whole and the elasticity of the skin are looked at; if there is excess skin, there is the alternative of a thigh lift. In the arms something similar happens: when there is significant laxity, liposuction is compared with an arm lift. On the back, localised accumulations are worked on, and in the area under the chin the technique is finer and is explained on the submental liposuction page.

VASER lipo in men and in women?

The indication is the same: fat deposits that do not respond to diet or exercise, skin with elasticity and good health. What changes is where the fat accumulates, which is why each body is examined separately. In the male chest, it is worth distinguishing whether what is in excess is fat or gland tissue, something decided at the consultation; there is more on the gynaecomastia page.

VASER liposuction recovery, week by week

The ASPS describes the typical course of recovery from liposuction. In the first week you need to keep an eye on pain, swelling and bruising, and limit activity a great deal. Between the second and third weeks you feel much better and, depending on your job, you can go back to it, with exercise still limited. Between the fourth and fifth weeks there should be no trace of bruising and the swelling begins to subside. From the sixth week the swelling keeps improving and you can gradually return to activity, with gentle exercise.

The SECPRE adds that it is normal for bruising and inflammation to appear and that a compression bandage or an elastic garment is used depending on the area. At Clínica EGOS we plan for roughly one week of initial recovery, which is adapted to each patient. To see how the entry marks evolve, you can read about liposuction scars.

What to expect from VASER liposuction results

The SECPRE states that the results of liposuction should not be assessed before three months have passed, and the ASPS notes that swelling can take several months to disappear completely. According to the ASPS, results are long-lasting as long as you keep a stable weight and stay fit, although a significant weight gain can change them.

The ASPS also reminds us that the result cannot be guaranteed in advance, that in some cases a single operation is not enough, and that liposuction does not correct loose skin and is not a treatment for cellulite. When people talk about defining the abdomen, what is sought is to define the contour; how far this can be achieved depends on your muscles and your skin. On the blog you can read about abdominal etching.

What does the quote for VASER lipo include and what does its price depend on?

We do not give figures before assessing you, because the price of VASER lipo depends on the number and size of the areas, the technique, the anaesthesia and the operating theatre time, and on whether it is combined with another surgery. Once the assessment has been done, the quote is sent to you in writing.

A clear quote itemises the fees of the surgical team, the operating theatre, the anaesthesia, the compression garments, the follow-up check-ups and what happens if a touch-up were needed. To compare between clinics, always compare the same things: the areas, the technique and the follow-up included. If you are interested in the circumferential approach (360 liposuction), at the consultation we explain how its quote is put together.

Where to have VASER lipo

Liposuctions are considered after an in-person assessment. On the liposuction in Alicante page you will find the information for that clinic, how to get there and how to ask for your first appointment. At the end of this page you can see the list of all our clinics.

Liposuction by area and related treatments

VASER lipo can be applied to different parts of the body and each has its own page: abdominal liposuction, flanks, thighs, back and arms. You also have fat transfer (lipotransfer), which reuses the fat removed; abdominoplasty; and, for the area under the chin, submental liposuction.
