Onda is a procedure that uses microwave energy to manage localized fat and skin elasticity together.
When fat appears to accumulate in the double chin or in specific areas of the body, we check the amount of fat and the degree of skin laxity,
and perform the procedure with a handpiece suited to the area.

| Item | Details |
|---|---|
| Ingredient/Mechanism | Microwave (Coolwaves, 2.45GHz). Delivers heat to the subcutaneous tissue to improve the elasticity of the skin and subcutaneous tissue. The heat is preferentially delivered to the fat layer |
| Depth Reached | Centered on the subcutaneous fat layer + dermis. Two types of handpieces — for deep and shallow layers — are used according to the area (with surface cooling) |
| Suitable For | The indication approved by Korea’s Ministry of Food and Drug Safety (MFDS) is improvement of skin and subcutaneous tissue elasticity (abdomen, thighs, etc.). Used for areas where both elasticity and fat are a concern, such as the double chin; other areas such as the cheeks are determined during consultation |
| Procedure Time | A few minutes to 30 minutes (varies by area) |
| Anesthesia/Pain Level | Generally no anesthesia needed. A warm sensation of heat moving across the area |
| Onset of Effect | 1–2 months |
| Duration | Around 6 months, cumulative with repeated treatments (varies by individual) |
| Recommended Frequency/Interval | About 3–4 sessions at 4-week intervals |
| Downtime | Redness and warmth may appear; recovery varies by individual |
| Main Side Effects | Temporary redness, swelling, warmth; rarely, a sense of nodularity or burns; differences between the left and right sides depending on the area |
| Manufacturer/Approval | DEKA (200W output, Coolwaves 2.45GHz). MFDS-approved indication: improvement of skin and subcutaneous tissue elasticity |
Onda is a procedure that uses 2.45GHz microwave energy. It delivers heat to the fat beneath the skin and the surrounding tissue to manage localized fat and skin elasticity. During the procedure, the skin surface is cooled, and the range and intensity are adjusted according to the amount of fat and the thickness of the skin.
Onda is considered when both fat accumulation and skin laxity are a concern together. On the face, it is applied to the double chin and jawline; on the body, it addresses localized fat, cellulite, and reduced elasticity in areas such as the abdomen and thighs.
When microwaves reach the tissue, molecules vibrate and generate heat. This heat acts on fat cells and the surrounding connective tissue to induce volume reduction and tissue remodeling, while also stimulating collagen in the dermis to improve elasticity.
The handpiece’s cooling keeps the epidermal temperature low, so it is designed to deliver heat to deeper layers while reducing the heat burden on the skin surface. Treatments are divided into multiple sessions because changes in fat and tissue do not occur all at once but accumulate over time.
It is not a treatment for reducing weight, but one that addresses localized fat and elasticity in specific areas. It is considered separate from weight management.
We generally recommend 3–4 sessions at about 4-week intervals as a base. This varies depending on the area and goal.
It is generally performed without anesthesia, with a warm sensation of heat moving across the area. Areas closer to the bone may feel slightly more stimulation.
Yes. The two treatments differ in how they deliver energy and in their treatment purpose, so they can be planned together. It is possible to receive both on the same day; the order, range, and intensity of treatment are determined after checking the amount of fat and skin condition.
Body-specific tips are used on the abdomen, thighs, and arms. Please refer to the body-specific page for details.
