Not all liposuction works the same way. Traditional liposuction removes fat mechanically, with the cannula physically breaking apart tissue as it moves.
Vaser Liposuction, or Ultrasonic Assisted Liposuction (UAL), takes a different approach by delivering ultrasound energy into the treatment area first, emulsifying fat cells before they are suctioned out.
This sequence matters because when the fat is liquefied, the surrounding tissue is left undisturbed. This means less post-operative discomfort, minimal bruising and a faster return to daily activities.
Vaser lipo also stimulates collagen production during the procedure, which encourages skin tightening in the treated area. The technique is well-suited to body contouring across multiple areas, from the abdomen and flanks to the arms, thighs, and back.
At Amaris B. Clinic, Vaser Liposuction is performed by Dr Ivan Puah under twilight sedation as a day-surgery procedure.

Vaser Liposuction (Ultrasonic Assisted Lipo) uses targeted sound energy to gently liquefy fat deposits before removal. The Vaser[1, 2, 3, 4, 5, 6, 7] technique preserves surrounding blood vessels and connective tissue – resulting in smoother, more natural body contours than traditional liposuction.
Key Benefits of Vaser Liposuction:
Refined by Dr Ivan Puah, our Vaser Lipo technique delivers transformative yet natural-looking results.
Vaser Liposuction is a form of ultrasonic-assisted liposuction performed under local anaesthesia. This fat removal procedure utilises ultrasound energy to gently break down unwanted fat tissues.
Tumescent fluid, a special mixture of lidocaine and saline used in liposuction to increase comfort and aid in faster recovery, is infiltrated to numb the targeted area and shrink the blood vessels.
A probe which emits high ultrasonic frequency is inserted to expand and contract the air bubbles within the tumescent fluid.
The probe oscillates at 36,000 times ultrasonic soundwaves per second, separating fat tissues from other connective tissues.
Even though the probe moves at a fast speed, it does not disturb the veins, arteries, and other connective tissues.

Once the fat is emulsified, Dr Ivan Puah will carefully suction the liquified fat and carry out body contouring.
Unlike traditional liposuction, which is more intrusive, Vaser Liposuction is gentle on the body.
It breaks down fat cells while leaving other important connective tissues relatively undisturbed; hence the incidence of tissue injuries is significantly reduced.
Vaser Liposuction can safely and reliably remove fat, contour the targeted area, and promote skin tightening.

Patients with mild to moderate skin laxity will notice an improvement in skin tightening in the treated area.
Maintain a disciplined lifestyle and following a balanced diet and frequent exercise routine.
Complement your results with other aesthetics treatments after 6 months.
While Vaser liposuction permanently removes fat cells from treated areas, new fat can still develop in untreated areas if calorie intake consistently exceeds expenditure.
Vaser Liposuction is an elective surgery, therefore it is not covered under insurance or Medisave.
What affects the cost?
Your total surgical fees vary based on several factors such as:
We provide before-and-after photos privately during your one-on-one consultation with Dr Ivan Puah. You will be able to view anonymised images of actual patients who had undergone Vaser Liposuction surgery.
They allow you to:
Disclaimer: While these clinical visuals are shared in-clinic for your education, MOH strictly prohibits displaying before/after images in ANY public advertising (website, social media, brochures etc.). We fully comply to ensure ethical patient communication, no unrealistic outcome promises and protection of patient privacy. Visual examples are for educational reference only - individual results vary based on your unique condition.
Choosing the right doctor with a keen aesthetic sense is crucial for achieving your desired silhouette and real results.
Think of a body sculpting procedure as a work of art in the making. The artist's expertise, experience, and deep grasp of the aesthetics of the human body are what distinguish a masterpiece from an ordinary work.
Ensure that the doctor is accredited by the Ministry of Health (MOH) Singapore to perform the procedure.
Seek lipo doctors performing a minimum of 100+ annually. High-volume practitioners will refine their techniques for optimal contouring accuracy and complication management.
Request comprehensive before and after case studies. Visual evidence demonstrates technical skill.
Do understand the benefits as well as potential side effects of the procedure. Clear your misconceptions and ask the doctor any questions you find relevant and necessary.
Discuss realistic outcomes, surgical risks and long-term maintenance. Transparent dialogue prevents post-procedure dissatisfaction and aligns expectations.
Compromise safety for cost. Avoid “bargain” packages lacking accredited facilities, trained anaesthetists or post-operative care.
Don’t overlook procedure-specific expertise. Don’t assume all lipo doctors possess equal skills in ultrasonic liposuction.
Don't withhold information during consultations. Undisclosed factors may cause anaesthesia reactions, poor wound healing or suboptimal outcomes.

Is Vaser Liposuction for weight loss?
Vaser Liposuction removes fat and contours the body; it is not a weight loss solution for obesity. You can consider our weight management programme if your objective is to lose weight.
Who should not have Vaser Liposuction?
How much fat can be taken in one procedure?
Singapore's Ministry of Health strictly limits fat removal:
We prioritise your safety while achieving optimal results.
Does Amaris B. provide aftercare treatments?
At Amaris B. Clinic, aftercare significantly assists you with faster recovery and ensures optimum results.
We have curated a bespoke aftercare program designed to help you with the healing process, such as MLD Therapy, skin firming and many others.
What not to do after Vaser liposuction?
Avoid alcohol, smoking, strenuous activities, including heavy household chores, water activities and, soaking in the bathtub. Follow the aftercare guide instructions. If you have any questions or concerns, contact the medical team for further advice.
What body part is most painful to Vaser liposuction?
Patients have shared that the inner thighs and abdomen are more sensitive than other areas. However, do note that discomfort and soreness are subjective experiences. You will also be given painkillers to manage any pain you may feel.
Why do I look bigger 3 weeks after Vaser liposuction?
The swelling you notice is fluid buildup post-liposuction. This is a common occurrence, and the swelling will subside on its own. This is why we highly recommend you get regular Manual Lymphatic Drainage massage to help with swelling. MLD therapy improves circulation and removes toxins, including fluid buildup, from your body.
How long should I take off work after Vaser liposuction?
If your work is desk-bound, you may return to work within 1-2 days post-op. If your job involves heavy lifting or frequent travelling, we recommend that you rest for at least 7 days before you go back to work.
What is the downside of Vaser liposuction?
You may experience temporary bruising, tenderness, soreness, and tingling sensations. All of these will subside in a few weeks, so be patient and diligent with your aftercare routine for an uneventful recovery.
When is lipo swelling the worst?
The swelling after liposuction peaks during the first three days and will subside in a few weeks.
Which hurts worse: VASER lipo or a tummy tuck?
Research indicates that patients who underwent a tummy tuck are experiencing more pain and discomfort than a liposuction procedure.
