Double Chin ONDA Liftingin Gangnam, Seoul
Double Chin ONDA Lifting targets the under-chin (submental) area, where a pocket of fat and skin laxity create a double chin. Coolwaves microwave energy at 2.45 GHz is preferentially absorbed by water-rich tissue, so it can warm the submental fat while also firming the overlying skin, with integrated cooling for surface protection. At QD Clinic in Gangnam, Seoul, a session usually takes about 20–40 minutes with little downtime. (Results vary by individual.)
Who it’s for
- A double chin from under-chin fat with mild skin laxity
- People who want to soften submental fullness without surgery
- Those who prefer a microwave-based option with little downtime
- Anyone pairing the under-chin with jaw or neck care
ONDA warms fat and firms skin gradually over a course; it is not surgery or a weight-loss treatment, and a large or mainly muscular fullness may need another approach. Suitability is confirmed at consultation.
How it works
Under the chin, ONDA delivers Coolwaves microwave energy at 2.45 GHz, which is drawn to water-rich tissue and warms the submental fat pocket while also warming the dermis to firm the overlying skin. Integrated cooling protects the surface. Over a short course, the warmed area may gradually reduce in fullness and feel firmer. Your settings and the number of sessions are personalized after an assessment.
THE MECHANISM, STEP BY STEP
01Microwave energy — Coolwaves
ONDA uses microwave energy at 2.45 GHz, called Coolwaves — a different part of the energy spectrum from ultrasound or radiofrequency.
02Drawn to water-rich tissue
Microwaves at this frequency are preferentially absorbed by water-rich tissue, so under the chin the energy can warm the submental fat pocket while also warming the dermis.
03Fat and skin, surface cooled
As the deeper fat is warmed, the overlying skin is also firmed, while integrated cooling protects the surface.
04Gradual change over a course
ONDA is usually planned as a short course of sessions; the warmed area may gradually reduce in fullness and feel firmer rather than change immediately.
Treatment areas
- Under-chin (submental) fat
- The pocket that forms a double chin.
- Under-chin skin
- Firming the overlying skin.
- Jaw-to-neck edge
- Refining the transition to the neck.
What the procedure is like
- 1Consultation and assessment of the under-chin
- 2Cleansing and mapping of the submental area
- 3Microwave (Coolwaves) delivery with cooling
- 4Soothing and aftercare guidance
Time: An under-chin session takes about 20–40 minutes.
Recovery & aftercare
- Little to no downtime; most people return to daily activities the same day.
- Temporary redness, warmth or mild tenderness under the chin may occur.
- Use sun protection and follow the aftercare guidance we provide.
What to expect over time
A general guide to how the days and months after treatment usually unfold. Results vary by individual.
DAY 0 First session
Warmth during treatment under the chin, eased by the integrated cooling; afterwards mild redness, warmth or slight tenderness that usually settles within hours. Most people return to daily activities the same day.
DAY 1-3 Settling
Any redness, warmth or mild tenderness under the chin generally eases. Makeup and normal skincare can usually resume as advised.
BETWEEN SESSIONS A gradual course
ONDA is usually a short course spaced as decided at consultation; change builds gradually from session to session rather than all at once.
2-3 MONTHS Gradual change
Over the course, reduced under-chin fullness and firmer skin develop gradually for many people. This is typically when results are assessed. (Results vary by individual.)
REVIEW Review
Your doctor reviews the outcome and discusses whether further sessions suit the under-chin.
Sessions & results
A short course of sessions is common, spaced as decided at consultation, with changes appearing gradually. Your plan is personalized. (Results vary by individual.)
How it compares
For a double chin, these options differ in what they act on — ONDA can warm the under-chin fat, while ultrasound lifts and radiofrequency firms the skin.
| Comparison | ONDA Lifting | Ultherapy PRIME | Thermage FLX |
|---|---|---|---|
| Energy | Microwave (Coolwaves, 2.45 GHz) | Focused ultrasound (imaging-guided) | Monopolar radiofrequency |
| Main action | Warms submental fat and firms the skin | Lifts lax skin at the SMAS | Tightens the dermis |
| Often chosen for | Under-chin fullness with mild laxity | Deeper under-chin skin laxity | Firming the under-chin skin |
| Sensation | Warmth with integrated cooling | Brief warmth at each point | Warm heating cycles with cooling |
| Downtime | Little to none | Little to none | Little to none |
Neither is “better” — they work differently and suit different goals. The right choice is decided after we assess your skin.
Safety & considerations
Possible reactions
- Temporary redness, warmth or mild tenderness under the chin
- Mild swelling or tenderness in the treated area for a short time
- Occasionally small areas of bruising
- Rarely, firm spots or small lumps under the skin that typically soften and settle
When to take extra care
- Pregnancy or breastfeeding — let us know at consultation
- Implanted electrical devices such as a pacemaker, or metal implants in the area — tell your doctor
- Active skin infection, inflammation or open lesions under the chin
- Recent fillers, threads or fat-dissolving injections in the area — tell your doctor so timing can be planned
- A history of keloid or difficulty with wound healing
ONDA warms fat and firms skin gradually over a course; it is not surgery or a weight-loss treatment, and a large or mainly muscular fullness may need another approach. Whether it is right for you is confirmed during consultation. Effects and downtime vary by individual, and side effects may occur.

It warms the under-chin fat and firms the skin gradually over a course, which may soften the look of a double chin; it is not surgery, and results depend on the amount and type of fullness. (Results vary by individual.)
They work differently — ONDA warms tissue with microwaves, while injections use a different mechanism. We advise which fits your under-chin at consultation.
Most people feel warmth eased by the integrated cooling; the under-chin can feel a little tender. Comfort options are discussed at consultation. (Results vary by individual.)
A short course is common, spaced as decided at consultation. (Results vary by individual.)
Little to none. Temporary redness or warmth may occur and usually settles quickly.
Yes. Our doctors consult in English directly, and 中文 / 日本語 can be arranged in advance. Tell us your language on WhatsApp before your visit.
Often considered together
Treatments that are sometimes planned alongside this one, decided at consultation.
+Jawline ONDA Lifting
The under-chin and jawline are often treated together for a cleaner lower-face line — decided at consultation.
+Fat-dissolving injection
For submental fat, injections use a different mechanism from microwave warming and may be considered instead of or alongside ONDA — decided at consultation.
+Thermage FLX for Neck Lines
If loose neck skin accompanies the double chin, radiofrequency firms the neck skin — sequencing decided by your doctor.
