Onda Lifting results timeline

Onda, made by DEKA, delivers microwave energy through a cooled handpiece. Coolwaves technology heats the fat layer selectively, which damages fat cells, while also warming the deeper skin to encourage firming. The body then clears damaged fat cells over several weeks. That is why Onda results appear gradually rather than on the day.

When	What you may notice	What is happening
Day 0	Warmth, mild redness and sometimes slight swelling	Targeted heating of the fat layer and dermis
Days 1–7	Swelling settles; the area may feel tender to touch	An inflammatory clean-up response begins
Weeks 2–4	Early softening of fullness under the chin or along the jaw	Damaged fat cells are gradually cleared
Weeks 4–8	Clearer contour and firmer-feeling skin	Fat clearance continues and collagen responds
Month 3	Result of the session is mostly complete	A good point to decide whether to repeat

What improves and what doesn't

Usually improves

Fullness under the chin
Soft jowls and a blurred jawline
Mild looseness that accompanies small fat pockets
Small stubborn areas on the body, such as the abdomen or arms

Usually does not change

A wide jaw caused by the masseter muscle
Significant excess skin or advanced sagging
Large-volume fat, which is a weight or surgical question
Skin texture, pores or pigmentation

Factors that influence your results

Energy delivered: Korean clinics price Onda by the joule. A larger area or a stronger plan uses more energy. Our guide to shots, lines and cc explains how these units work.
How much fat is present: a moderate pocket usually shows a clearer change than very thin or very full areas.
Skin elasticity: firmer skin adapts better as volume reduces.
Weight stability: weight gain can enlarge remaining fat cells and blur the contour.
Number of sessions: some people need more than one session to reach their goal.

How to maximize and maintain your results

Onda targets fat and skin, so it pairs well with treatments that work on other causes of a full lower face. If the masseter muscle makes your jaw look wide, jaw Botox addresses that directly. For a stubborn small pocket under the chin, a fat-dissolving injection can be added. Our page on the double chin compares every option.

Drink plenty of water and stay active in the weeks after treatment.
Keep your weight steady to protect the new contour.
Avoid saunas and very hot baths for a day or two.
Use sunscreen daily to protect collagen.

Realistic expectations and when to repeat

Onda gives a gradual, natural-looking refinement, not the instant change of liposuction. Treated fat cells that the body clears are not replaced, so results can last well as long as your weight is stable. The skin-firming part fades over time like any collagen treatment. If you are weighing it against RF contouring, see Onda Lifting vs InMode. Our medical team's Onda Lifting review covers value, and energy plans are on the Onda Lifting price page. Prices are in Korean won (KRW), exclude 10% VAT, and are confirmed at your consultation.

Tracking your progress

Because change happens after you leave Seoul, photos are the best way to see it. Take them before treatment and at four and eight weeks.

Use the same spot, with even daylight from the front.
Take side profiles with your chin level and shoulders relaxed.
For body areas, use the same clothing and posture each time.
Note your weight on the day of each photo.

If your results aren't what you expected

Allow the full eight weeks before judging. If the change is still small, contact Dernia with your photos so your doctor can review them. They may suggest a second session, a different energy plan or another treatment if muscle or laxity is the main issue. Browse our other results guides to compare options.

When will I see Onda Lifting results?

Results are gradual. Most people start to notice a softer contour at about four weeks, with the change continuing to build up to about eight weeks.

How many Onda sessions will I need?

Some people are happy after one session, while others need more to reach their goal. Your doctor advises the number and spacing after assessing the area.

Is there swelling after Onda?

Mild swelling, redness and tenderness are possible and usually settle within days. Most people continue their normal plans.

Are Onda results permanent?

Fat cells that the body clears are not replaced, so results can last well if your weight stays stable. Remaining fat cells can still grow with weight gain, and skin continues to age.

Can Onda be used on the body?

Yes. It is also used on small body areas such as the abdomen and arms. Your doctor will advise which areas suit it.
