Who it suits
- Fullness under the chin or along the jawlineThe microwaves target fat cells selectively, sparing the tissue around them.
- A fuller face that needs its contour addressed before liftingReducing the fat first changes the outline in a way lifting alone cannot.
- Body areas such as the abdomen, flanks or thighsThe same handpieces are used for these body areas too.
What it does
The Coolwaves technology in ONDA operates at 2.45 GHz, a frequency that fat cells absorb preferentially, while a cooled handpiece protects the skin above them throughout treatment. A single session both reduces localised fat and tightens the skin over it, which is the reason it is used before, or alongside, lifting treatments on faces with excess fullness.
How it is planned here
The dermatologist determines at consultation whether the underlying issue is excess fat, skin laxity, or a combination of the two. Where the lower face is fuller, ONDA is used first, with a lifting device such as Ultherapy or Thermage following once the contour has already changed. The reasoning behind this sequence is set out in the clinic's own ONDA video on YouTube.
What to expect
You will feel warmth during the session itself, with mild redness afterward. The fat-reduction effect becomes visible over four to eight weeks, and for the face, a typical course is two to four sessions.
Questions
Does ONDA replace lifting?
No. It changes volume; lifting devices change position. Many patients need both, in that order.
Downtime?
None. Mild redness for a few hours.
Price?
By area and session count, quoted at consultation.
I have never had a lifting treatment. Where do I start?
With a consultation and a 3D Meta-Vu scan, not with a device. The dermatologist shows you on screen where your face has lost volume and where the skin has loosened, then explains which single treatment, if any, would change what you see. Many first-time patients leave with one treatment, not a package.
Does lifting hurt, and will I look different the next day?
Numbing cream is applied for 20 to 30 minutes first. Ultrasound treatments feel like brief deep heat; radiofrequency feels like warm pulses. Most patients go to dinner the same evening with no visible sign of treatment. Any mild redness is gone within hours.
How long before I see a result, and how long does it last?
Some tightening is visible early, but the main result builds as new collagen forms over two to three months. One treatment typically holds for a year or more, after which it is repeated as the face requires.
Can I do it on the day of my consultation?
Yes for Ultherapy, Thermage, Sofwave, Xerf and ONDA. Allow about two hours including the scan, numbing and treatment.
What does it cost?
Prices are published on this site in Korean won and depend on the shot count, which is decided from the scan. Ultherapy Prime starts at ₩450,000 per 100 shots and Thermage FLX at ₩1,450,000 per 300 shots. Cosmetic treatment carries 10% VAT.
