What is ONDA microwave lipolysis? How it works to eliminate Double Chin, its effects, and current prices in Hong Kong/Taiwan

August 20, 2026 · DAN-A in Myeongdong

ONDA microwave lipolysis is a key term many people search for when looking into treatments to eliminate their Double Chin. If you can’t lose weight around your Double Chin, it might not be due to overall body weight but rather localized fat accumulation. This article explains the mechanism behind ONDA microwave lipolysis (Coolwaves), the areas it can target, how it differs from other lipolysis methods, as well as the pricing and pre-treatment considerations that are important for readers in Hong Kong and Taiwan. Straight answer: ONDA Coolwaves is a non-invasive treatment that uses microwave energy to heat deep within the skin and destroy fat cells, thereby reducing Double Chin and localized fat accumulation. The effectiveness and number of sessions required depend on an individual’s fat thickness.

What is ONDA microwave lipolysis? What’s the working principle behind it?

ONDA makes use of Coolwaves microwave technology developed in Italy, which uses 2.45GHz microwave energy to precisely heat the subcutaneous fat tissue and fibrous membranes. This triggers metabolic reactions in fat cells while simultaneously stimulating the production of new Collagen. Unlike traditional “fat dissolving” methods, ONDA requires no injections, no freezing, and is not an invasive procedure. Instead, it delivers treatment by moving a probe across the skin’s surface, leaving no scars in the process.

Which areas can ONDA improve?

The most common applications for the treatment on the face are addressing a Double Chin and excess fat in certain areas of the cheeks, helping to define the jawline more clearly. For body areas, it’s often used on the abdomen, waist, inner Thighs, arms, and other parts prone to fat accumulation and cellulite. Since it’s a non-invasive procedure with no recovery period required, patients can return to work and daily activities as usual right after the treatment.

A Comparison of ONDA Microwave Lipolysis with Other Fat Reduction Methods

What makes ONDA different from other fat-dissolving methods?

The common fat-dissolving methods available on the market can be roughly divided into three categories. Cryolipolysis uses low temperatures to cause fat cells to die off, and this process may bring noticeable freezing pain. Injection-based fat-dissolving treatments use medications to break down fat; they are invasive procedures that can result in bruising and swelling. ONDA, on the other hand, utilizes microwave heating—there are no needles or incisions involved, and it eliminates the risk of frostbite common with cryolipolysis. With a relatively short recovery period, it represents a milder alternative.

When can I see the results? How long do they last?

ONDA doesn’t eliminate fat immediately after the treatment; instead, it relies on the body’s metabolism to break down the fat. Usually, changes in body contours can be seen 2 to 4 weeks after the treatment, with results improving as metabolism continues. Since everyone’s metabolic rate varies, it’s generally recommended to undergo 2 to 4 sessions spaced about 2 to 4 weeks apart to achieve noticeable and sustained sculpting effects. Once weight remains stable, these results can last for a long time.

Pre- and Post-Procedure Tips for ONDA Microwave Lipolysis

Pre- and post-surgery precautions

  • If you have skin inflammation or unclosed wounds before treatment, you should inform the doctor first so they can assess whether it’s appropriate.
  • Pregnant women and those with electronic medical devices such as pacemakers are not recommended for this treatment.
  • Mild warmth or tightness may occur after the treatment, but these symptoms usually subside within the same day.
  • Drink plenty of water after treatment to help your body metabolize and break down the fat, resulting in more noticeable effects.

Frequently Asked Questions FAQ

Is ONDA painful?

During ONDA treatment, most people experience a warm sensation, which is within an acceptable range. Unlike cryolipolysis that causes noticeable freezing pain, ONDA doesn’t require injections either. The actual feeling may vary slightly depending on the treatment area and energy settings. If it feels too hot, you can always inform the doctor so adjustments can be made.

Does ONDA work from the first use?

You might experience mild discomfort after a single treatment, but to achieve noticeable sculpting results, it usually takes 2 to 4 sessions, along with adequate hydration to support metabolism. Expecting a significantly slimmer chin after just one session can lead to disappointment, so it’s recommended to complete the full course as planned by your doctor to obtain the best possible results.

Who is ONDA suitable for?

ONDA is particularly effective for dealing with localized fat issues such as a Double Chin that won’t go away no matter how much you try to lose weight, excess fat in the cheeks, or stubborn fat and cellulite in specific areas of the body. It’s not meant to replace overall weight loss. For those suffering from systemic obesity or being overweight, it’s recommended to first control weight through diet and exercise before using ONDA to shape the body’s contours.

There are many causes of a Double Chin—it could be due to fat accumulation, or it might be related to bone loss or skin laxity. Identifying the root cause is key to addressing the issue effectively. If you’re not sure whether ONDA is right for you or if you need it combined with other lifting treatments, feel free to schedule a video consultation or in-person appointment with DAN-A at Myeongdong to discuss and create the most suitable anti-aging treatment plan for you.
