What Is VASER® Liposuction?
VASER® liposuction is a type of ultrasound-assisted body contouring technique. It uses sound waves to gently break down fat before it’s removed — making the procedure more precise and often less traumatic than traditional liposuction.
VASER stands for Vibration Amplification of Sound Energy at Resonance. That sounds technical, but here’s the simple version: VASER liquefies fat using ultrasound energy, so it’s easier to remove without damaging nearby nerves, blood vessels, or connective tissue.

How VASER® Liposuction Works
- Tumescent solution is injected into the treatment area. It numbs the tissue and prepares the fat for easier removal.
- A small ultrasound probe delivers controlled energy to break down the fat. This step emulsifies the fat, turning it into a liquid.
- Gentle suction removes the liquefied fat with less trauma than traditional methods.
- Finishing touches may include small cannulas to sculpt the area and improve shape.
Because the fat is already softened, the surgeon doesn’t need to force the cannula through tough tissue. That makes VASER more precise and less aggressive — especially helpful in dense, fibrous areas like the chest, back, or male flanks.
VASER® vs Other Liposuction Techniques
VASER® liposuction stands out because it uses ultrasound energy to liquefy fat before removal. This makes the fat easier to extract and allows the surgeon to sculpt more precisely, especially in areas with dense or fibrous tissue like the chest or back.
In contrast, traditional liposuction doesn’t use any energy source — the surgeon manually breaks up the fat with a blunt cannula. While effective, this approach can be more traumatic to surrounding tissues and may result in longer recovery or more bruising.
Power-assisted liposuction (PAL) uses a vibrating cannula to help dislodge the fat mechanically. It requires less physical effort than traditional lipo and performs well in fibrous areas, but it doesn’t offer any skin-tightening benefits or the same degree of precision as VASER.
Only VASER® uses ultrasound to emulsify the fat, which:
- Makes extraction smoother and less aggressive
- Provides mild skin contraction thanks to heat-stimulated collagen
- Preserves more of the surrounding blood vessels and nerves
- Produces fat that remains viable for fat transfer (e.g. to the buttocks or breasts)
Some experienced surgeons even combine VASER® and PAL to get the benefits of both technologies — emulsifying the fat with ultrasound, then using vibration for faster, efficient removal.
A retrospective study of 175 VASER liposuction procedures published in 2025 found high patient satisfaction and minimal complication rates — even in large-volume fat removal cases.
Who Is VASER® Liposuction For?
VASER® may be right for you if:
- You’re close to your ideal weight but still have localized fat that won’t go away
- You’re looking for more sculpted results, not just slimming
- You want to treat difficult areas, like the upper back, male chest, or inner thighs
- You plan to combine it with fat grafting to areas like the breasts or buttocks
It’s commonly used on:
- Abdomen
- Love handles (flanks)
- Thighs and inner knees
- Arms
- Back or bra bulge
- Male chest (gynecomastia)
- Chin and jawline
If your skin still has decent elasticity, VASER® may give a subtle skin tightening effect as well. That’s because the ultrasound heat gently stimulates collagen. But let’s be realistic — it won’t dramatically lift loose or sagging skin. For that, you’ll need surgical lifting or combined technologies.
Benefits of VASER® Liposuction
VASER offers a combination of precision and gentleness that many other techniques don’t.
- Less trauma to tissues: Since the fat is already emulsified, less force is needed during suction.
- Smooth sculpting: Surgeons can contour more precisely — especially useful in high-definition liposuction.
- Helps preserve blood vessels and nerves: Less bruising and faster recovery.
- Mild skin contraction: A bonus in areas like the lower belly or arms.
- Fat remains usable for transfer — unlike laser-based methods, VASER doesn’t burn the fat.
A large-scale safety analysis published in 2024 also found that patients with lower BMI had fewer complications, though results were still favorable across all BMI ranges when handled by experienced surgeons.

Recovery and Aftercare
You’ll likely return to light activities within 2–5 days. Most people can go back to work within a week, depending on the area treated. Some surgeons use local anesthesia for smaller zones, while larger sessions may require general anesthesia.
Expect:
- Swelling and bruising for 1–2 weeks
- Soreness or firmness for several weeks
- Compression garments for 3–6 weeks
- Occasional numbness or tingling
In a 2023 review of over 300 VASER procedures, complication rates were low. The most common issues were mild seromas (fluid pockets), especially in patients with high BMI or those who underwent large-volume liposuction.
Tip: Some surgeons recommend lymphatic massage to speed up recovery and reduce swelling.
Potential Risks
Like any surgical procedure, VASER® liposuction has risks, though they are uncommon with skilled surgeons:
- Seromas (fluid buildup)
- Contour irregularities
- Burns (rare but possible if the device is misused)
- Asymmetry or need for minor revision
- Prolonged swelling or numbness in some areas
Because VASER® uses energy, overheating is technically possible — but studies show this is rare when the proper technique is used.
Cost of VASER® lipo in Belgium
VASER® requires more time, technology, and training — so it’s generally more expensive than basic liposuction. Pricing in Belgium depends on the surgeon, treated zones, and whether it’s paired with fat transfer.
- Single small zone: from €1,800
- Larger zones: from €2,200
- Multiple areas or hi-def sculpting: €3,000 and up
Final Thoughts
VASER® liposuction is a major step forward in fat removal technology. Whether you’re looking for a more athletic shape, better muscle definition, or smoother results in tricky areas, it offers significant advantages — especially when performed by a surgeon who specializes in it.
Just keep in mind: it’s not magic. While VASER® can enhance your shape and subtly tighten skin, it won’t replace weight loss or surgical lifting when needed.
