Hello, I’m Dr. Kim Yeon-Jin , Medical Director of UH CELL Gangnam (formerly Dr. Petit Clinic Gangnam). Today, I’d like to introduce Body Onda, one of the most frequently requested body contouring treatments at our Gangnam clinic.

As summer arrives, we naturally start wearing lighter clothing. During this season, many people focus on losing weight by combining a healthy diet with regular exercise. Especially in a busy city like Seoul, many people are looking for efficient ways to manage their body and achieve their fitness goals.

However, even after losing weight, certain areas can be especially stubborn when it comes to fat reduction. The upper arms, abdomen, and thighs are some of the most common trouble spots. As a result, many people find that although the number on the scale goes down, they’re still not satisfied with their body contours.

One treatment that can help in these cases is Body Onda. Recently, it has gained significant attention in Korea’s aesthetic medicine field as an effective option for improving body contours.

So, what exactly is Body Onda?

Body Onda is a body contouring and lifting device developed in Italy. Since it was specifically designed from the start to improve body contours and reduce localized fat, it is particularly effective for treating areas of the body with stubborn fat, rather than being used for facial treatments.

When used on the face, Body Onda is typically applied to areas where fat reduction is desired, such as the double chin or the fat around the cheekbones. Today, this treatment is used in a variety of ways in Korea for both facial and body contouring.

One of Body Onda’s key features is its use of Coolwaves®, a proprietary microwave technology. Unlike conventional ultrasound, radiofrequency, or laser-based devices, it works through a different mechanism to target unwanted fat.

How Does Body Onda Work?

To put it simply, Body Onda works on a principle similar to that of a microwave oven.

Instead of heating from the outside like a flame, a microwave warms food from within. In a similar way, Body Onda delivers energy to the targeted area, causing the temperature to rise first in the deeper fat layers beneath the skin.

During this process, the fat cells are affected by the targeted energy. After the treatment, the disrupted fat is gradually cleared from the body through the lymphatic system as part of the body’s natural metabolic processes. This treatment approach has been gaining increasing attention in Korea’s aesthetic medicine field.

Body Onda offers more than just fat reduction. It may also provide the following benefits:

  • Improved body contouring
  • Enhanced skin firmness and elasticity
  • Reduced appearance of cellulite

Because Body Onda also has skin-lifting properties, it helps stimulate collagen production in the dermis. As a result, patients may experience not only improved skin firmness but also enhanced body contours. These combined benefits are one of the reasons the treatment has become increasingly popular among people seeking body contouring in Seoul.

Can Body Onda Help Reduce Cellulite?

Cellulite occurs when the fibrous connective tissue beneath the skin becomes tight and pulls against the surrounding fat cells, causing the skin’s surface to appear uneven or dimpled.

Body Onda uses controlled thermal energy to help soften and loosen these fibrous connective tissue bands. As the tension is reduced, the fat cells can redistribute more evenly, which may help improve the appearance of cellulite.

For this reason, Body Onda is especially popular for treating areas where cellulite is most common, such as the thighs and abdomen. These benefits have also made it a frequently requested body contouring treatment at our Gangnam clinic.

The abdomen is a relatively large treatment area and often contains a significant amount of fat. For this reason, dividing it into smaller sections—such as the upper abdomen, flanks (love handles), and lower abdomen—and treating each area individually can often produce more effective results.

Number of Treatment Sessions and Recommended Interval

One of the most common questions we receive is how many treatment sessions are recommended.

Although treatment plans vary from person to person, 3 to 5 sessions spaced about one week apart are commonly recommended. Because the body’s fat layer is generally thicker and deeper than the face’s, achieving optimal results often depends on the cumulative effects of multiple treatments.

With consistent treatment, many patients notice more visible improvements in their body contours over time. This gradual, cumulative approach is also the standard recommendation for body contouring treatments in Korea.

How to Achieve Faster Results

If you’re looking for more noticeable improvements in your body contours, Body Onda can also be combined with HIFU (High-Intensity Focused Ultrasound) treatments for enhanced results.

To explain this, I often use the example of reverse searing a steak. With this cooking method, the inside of the steak is cooked first, and then the outside is quickly seared over high heat to finish it.

Body contouring can be thought of in a similar way.

First, Body Onda heats the deeper fat layers beneath the skin. Then, HIFU is used to tighten the more superficial layers. By targeting different tissue depths, the two treatments can complement each other and potentially provide greater improvements in body contouring. This combination approach is commonly used in aesthetic clinics across Korea.

How Do You Choose the Right Clinic for Body Onda?

It’s time for a quick PR break. Especially in a large city like Seoul, choosing the right clinic is an important part of achieving the best possible results.

When choosing a clinic for Body Onda treatment, I recommend looking for the following:

1️⃣ A clinic with extensive experience performing Body Onda treatments

Ideally, choose a clinic that can customize the treatment settings and number of sessions based on your individual fat distribution, body goals, and skin condition.

2️⃣A clinic with experienced medical professionals

Because the Body Onda handpiece is relatively large, proper positioning and consistent contact with the treatment area are essential for achieving optimal results.

3️⃣ A clinic with extensive experience in patient safety and treatment management

Although the risk is very low, most energy-based lifting devices carry a small risk of heat-related burns. For this reason, it’s best to choose a clinic with extensive experience in performing these treatments safely and effectively. This is also considered an important standard in Korea’s aesthetic medical practice.

When I was practicing at Dr. Petit Clinic Gangnam, I performed a large number of body contouring and lifting procedures. The clinic has since been renamed UH CELL Gangnam (formerly Dr. Petit Clinic Gangnam).

Today, I continue to provide personalized consultations at UH CELL Gangnam, drawing on experience from a wide range of body contouring cases.

In Closing,

To be honest, Body Onda alone won’t lead to dramatic weight loss.

However,

  • You’re struggling to reduce stubborn fat in specific areas.
  • You want to improve and refine your body contours.
  • You’re concerned about the appearance of cellulite.

When combined with a healthy diet and regular exercise, Body Onda often provides higher patient satisfaction and more noticeable body contouring results. This combination approach is also widely emphasized in Korea’s aesthetic medicine trends.

If you’re concerned about stubborn upper arm fat or your abdominal contours, the best approach is to consult with a qualified physician to determine the treatment plan that’s right for you. If you’re considering treatment in Seoul, be sure to have a thorough consultation before making your decision.
