Onda Lifting uses 2.45 GHz Coolwaves microwave energy that is absorbed mainly by the fat layer, so it can reduce localized fat and tighten skin at the same time while core cooling protects the surface. It is needle-free with little or no downtime, and results build over about 6 to 12 weeks. Ultherapy, by contrast, uses focused ultrasound to lift at the deep SMAS layer, and the two are often combined.
Onda Lifting has become one of the most asked-about contouring treatments in Seoul, especially for fullness along the jawline and under the chin.
This guide explains how Onda works, who it suits, what the session and recovery are like, when results appear, how it compares with Ultherapy, and how to plan it at Glory Clinic in Gangnam during a trip to Korea.
| Onda Lifting | Ultherapy Prime | |
|---|---|---|
| Energy | 2.45 GHz Coolwaves microwaves | Micro-focused ultrasound with real-time imaging |
| Main target | The fat layer (subcutaneous fat) | Deep layers up to the SMAS |
| Main effect | Reducing localized fat plus skin tightening | Structural lifting of jawline and neck laxity |
| Comfort | Core cooling keeps the surface from heating up; needle-free | Brief deep-heat pulses; numbing cream commonly used |
| Downtime | Little or none | Minimal; mild redness or swelling for hours to days |
| Results | Build over about 6 to 12 weeks | Build over about 2 to 6 months |
What Onda Lifting is
Onda is a recently developed microwave lifting device that has been well received by many patients. It uses patented Coolwaves microwave energy at 2.45 GHz, which is absorbed selectively by fat cells. Roughly 80% of the energy is delivered to the fat layer and only about 20% reaches the skin, while core cooling keeps the skin's surface from heating up.
The heat stresses fat cells so they release their contents, which the body clears naturally over the following weeks. At the same time, Onda stimulates collagen regeneration for firmer, more elastic skin, which is why it is used for both lifting and fat reduction.
Who Onda suits
Onda suits people who want to reduce localized fullness, for example along the jawline, the lower cheeks or under the chin, and firm the skin at the same time, without needles or downtime. People whose main concern is deep sagging rather than fullness may be better matched with an ultrasound lift such as Ultherapy, or a combination.
The session at Glory Clinic
Your Onda plan is set in a one-on-one consultation with the doctor. The flow is: consultation, an explanation of the Onda process, cleansing and preparation, the Onda treatment, post-treatment care, and aftercare instructions.
Glory Clinic follows a strict protocol with the genuine ONDA device and genuine tips, delivering microwave energy safely at the correct dose.
Recovery and results
Onda is needle-free and usually requires little or no downtime, so most people go straight back to their day. Results build progressively over about 6 to 12 weeks as fat cells are cleared and collagen forms, and occasional maintenance sessions help sustain fat reduction and tightening.
Onda vs. Ultherapy
The two work on different layers with different energy. Onda's microwaves are absorbed mainly by fat, so it is the better fit when fullness is part of the problem. Ultherapy Prime's focused ultrasound reaches the SMAS, the deep layer tightened in a facelift, so it is the better fit for structural lifting of the jawline and neck.
Because they complement each other, they are often combined: Onda to reduce fullness and Ultherapy to lift. At Glory Clinic, Ultherapy Prime is planned to avoid side effects such as cheek hollowing, and whether to combine is decided with the medical director.
What published research reports
In a study of ten women with moderate to severe laxity under the chin, two sessions of a 2.45 GHz microwave device 30 days apart improved the submental skin laxity grade from an average of 3.6 to 2.3 twelve weeks after the final session, with no adverse effects reported and minimal discomfort [1].
The study is small, and results vary from person to person. Onda is a non-surgical treatment and is not a substitute for surgery.
Planning Onda in Seoul as an international patient
With little or no downtime, Onda fits easily into a short trip, and results continue to develop after you return home. Glory Clinic is in Gangnam, 30 m from Exit 4 of Eonju Station (Line 9), with valet parking. Book on WhatsApp (+82-10-7908-7525), KakaoTalk, LINE or WeChat, or call +82-2-6958-7525; same-day treatment is available.
Frequently Asked Questions
What kind of energy does Onda use?
2.45 GHz Coolwaves microwave energy, absorbed mainly by the fat layer, with core cooling protecting the skin's surface.
Does Onda reduce fat?
Yes. It targets the fat layer to reduce localized fat and also stimulates collagen for firmer skin.
Is Onda painful?
Core cooling keeps the surface from heating up, and the treatment is needle-free. Most people find it comfortable.
Is there downtime?
Usually little or none.
When will I see results?
Results build progressively over about 6 to 12 weeks.
Onda or Ultherapy: which should I choose?
Onda suits fullness and fat reduction with tightening; Ultherapy suits deep structural lifting. They are often combined, and the medical director decides with you.
Can I have Onda during a short trip to Seoul?
Yes. With little or no downtime it fits a short stay, and same-day treatment is available at Glory Clinic.
