Hello! This is Seye Clinic, embracing all the beauty in the world.
If you are considering Onda Lifting in Seoul for non-surgical fat reduction, you typically need between 40,000 to 80,000 Joules depending on your facial fat volume. This 2.45GHz microwave treatment effectively targets stubborn double chins and tightens skin with virtually zero downtime.
In our practice, we consistently see patients who are frustrated by stubborn lower facial fat that diet and exercise simply cannot resolve. A question that came up three times last week alone was, "How is Onda different from traditional HIFU?"
Onda Lifting is a non-invasive body and facial contouring device that utilizes specialized 2.45GHz microwaves (Coolwaves®). According to a 2020 study published in the Journal of Plastic, Reconstructive & Aesthetic Surgery, these specific microwaves bypass the epidermis, delivering 80% of their energy directly into the subcutaneous fat layer.
This mechanism allows Onda to heat and disrupt fat cells while simultaneously stimulating collagen contraction in the dermis. The device features a built-in contact cooling system that maintains a surface temperature of 5°C, protecting the skin from burns and significantly reducing discomfort. For international patients visiting Gangnam, this means you can achieve noticeable fat reduction and skin tightening without the severe pain or recovery time associated with older technologies.

When addressing facial sagging and excess fat, it is crucial to understand how different premium lifting devices compare. What we typically observe is that patients often confuse fat reduction with muscle fascia tightening.
• Onda Lifting: Primarily targets the fat layer using microwaves. It is excellent for reducing double chins and cheek fat while providing surface tightening. Pain is minimal, often described as a warm massage.
• Ultherapy Prime: Targets the SMAS (Superficial Musculoaponeurotic System) layer using high-intensity focused ultrasound (HIFU). It provides foundational lifting but does not primarily destroy fat. It typically requires 300 to 600 lines and involves moderate to high discomfort.
• Sofwave: Targets the mid-dermis using synchronous ultrasound parallel beam technology (SUPERB™). It is ideal for improving fine lines and skin elasticity but is not designed for fat reduction.
While Onda is highly effective for fat reduction, it has limitations. It will not lift deeply descended muscle fascia like Ultherapy does. Therefore, we often recommend a combination approach. A typical session of Onda takes about 20 to 30 minutes, and results can last 6 to 12 months depending on lifestyle factors.

One of the most critical factors in your Onda Lifting treatment is the total energy delivered, measured in Joules (J). In our clinical experience, under-treating is the most common reason for unsatisfactory results.
Target Area | Recommended Joules |
|---|---|
Double Chin (Targeted) | 40KJ |
Full Face (Contouring) | 60KJ |
Full Face + Double Chin | 80KJ |
However, a disturbing trend in the aesthetic market is the use of counterfeit devices or recycled tips. If a clinic offers prices that seem too good to be true, it is a major red flag. Fake Onda devices cannot maintain stable energy output, which not only leads to poor results but also increases the risk of severe burns. Always verify that the clinic uses a 100% genuine Onda device with official certification marks on the machine and handpieces. At Seye Clinic, we guarantee authenticity for every single procedure.
Gangnam is the epicenter of global aesthetic dermatology, and Seye Clinic stands at the forefront of this fast-paced industry. We are led by Key Opinion Leader (KOL) specialist doctors who continuously refine their techniques based on the latest clinical data.
At Seye Clinic, we guarantee the use of 100% genuine equipment. We transparently show our patients the authentic device and tips before every procedure. Furthermore, we do not believe in a one-size-fits-all approach. Because facial bone structure and fat distribution vary wildly, especially among our diverse international patient base, we meticulously design a custom Joule distribution plan for every individual. One specific detail we focus on is the precise angulation of the handpiece along the jawline, ensuring maximum microwave penetration into the submental fat pad while avoiding the thyroid gland. This level of anatomical precision is what separates a standard treatment from a premium clinical outcome.
Your journey at Seye Clinic begins with a comprehensive consultation. We assess your skin thickness, fat volume, and sagging degree using advanced diagnostic tools. Based on this, our specialists determine the exact Joule count required—whether it is 60,000J for the lower face or 80,000J for comprehensive contouring.
The treatment itself is remarkably comfortable. The 5°C cooling system ensures the surface remains cool while the deep tissue is heated. We continuously monitor your skin's response throughout the session.
For our international patients, we provide dedicated English-speaking staff to guide you through every step, ensuring clear communication. Since there is virtually zero downtime, you can immediately return to exploring Seoul, shopping, or enjoying cafes right after your visit to our clinic, conveniently located just a 1-minute walk from Gangnam Station.
• Onda Lifting uses 2.45GHz microwaves to selectively destroy fat cells and tighten skin.
• Optimal results require customized energy levels, typically ranging from 40,000 to 80,000 Joules.
• Beware of unusually cheap treatments, as fake devices can cause burns and yield poor results.
• Onda is virtually painless with no downtime, thanks to its advanced 5°C contact cooling.
• Seye Clinic in Gangnam guarantees 100% genuine devices and personalized treatment plans.
Q: How many sessions of Onda Lifting do I need to see results?
A: Many patients notice an immediate tightening effect after just one session. However, for optimal fat reduction, the destroyed fat cells take 3 to 4 weeks to be naturally eliminated by the body. We typically recommend a series of 3 sessions spaced one month apart for long-lasting V-line contouring.
Q: Is Onda Lifting really painless compared to Ultherapy?
A: Yes, it is significantly more comfortable. Because the 2.45GHz microwaves bypass the epidermis and the device features a 5°C contact cooling system, most patients describe the sensation as a warm, relaxing massage. You do not need numbing cream, unlike with Ultherapy which can cause deep, aching discomfort.
Q: How do I know if a clinic is using a fake Onda device?
A: Always look for the official "ONDA" logo and certification marks on the machine and handpieces. Additionally, be wary of prices that are drastically lower than the Gangnam average. At Seye Clinic, we transparently verify our 100% genuine equipment with every patient before starting the procedure.
Q: Can I combine Onda Lifting with other treatments on the same day?
A: Absolutely. In our clinical practice, combining Onda Lifting (to reduce fat) with Ultherapy Prime (to lift the deep SMAS layer) is one of the most effective protocols for comprehensive facial rejuvenation. Since Onda has no downtime, it pairs perfectly with other non-invasive procedures.
