Most people need three to six ONDA Body sessions, spaced about two to four weeks apart, for stubborn fat or cellulite. At Re:berry Hongdae, the exact number depends on the area, fat thickness, cellulite severity and skin laxity. Change builds gradually and is usually assessed two to three months after the final session.

Why does ONDA Body need several sessions?
ONDA Body uses microwave energy to heat fat and connective tissue. Each session affects a portion of the targeted fat cells, which the body then clears gradually over weeks. Collagen stimulation for firmer skin also takes time. Repeating sessions at intervals lets the body process each round before the next, which is why a course usually works better than a single treatment.
What changes the number of sessions?
- Goal: Fat reduction on the abdomen may need fewer sessions than cellulite on the thighs.
- Fat thickness: Thicker pockets often benefit from more rounds.
- Cellulite grade: Deeper dimpling generally needs a longer course.
- Skin laxity: Loose skin may need added tightening treatments.
- Response: Some people respond faster; the doctor reviews progress and adjusts.
A typical course at Re:berry Hongdae
- Consultation: The doctor examines the area and sets a provisional number of sessions.
- Sessions 1–3: Spaced two to four weeks apart.
- Review: Progress is checked, and the plan may be extended or finished.
- Final assessment: About two to three months after the last session.
Results vary by individual, and ONDA Body is not a weight-loss treatment. Stable weight and regular activity help preserve change.
Can sessions be combined with other treatments?
Yes. For loose skin, Ulthera Body may be added; for swelling, Vacumed; and Re:berry also pairs the Berry Slim contour injection with ONDA. Combining approaches can sometimes reduce the total number of ONDA sessions needed. Read ONDA Body for contour and cellulite for a fuller guide.
What happens between sessions?
Between visits, the treated area may feel tender or slightly firm for a few days, then return to normal. Staying hydrated, walking or exercising regularly and keeping a steady diet support the body as it processes treated fat. Avoid judging results too early; change from fat reduction often becomes clearer only after several weeks.
What if I am only in Seoul for a short time?
A single session is possible on a short trip, as there is usually no downtime, but one session alone typically gives limited change. Some visitors plan sessions across repeat trips. Discuss timing at consultation.

Related questions
Can I do ONDA Body sessions closer together?
Sessions are usually spaced two to four weeks apart to give the body time to clear treated fat and allow tissue to recover. Doing them much closer may not speed results and could increase tenderness. Your doctor will set an interval appropriate to the area and your response.
Will I need maintenance after my course?
Not everyone does. Treated fat cells are not usually replaced, but remaining cells can grow with weight gain, and cellulite can return with hormonal change. Some patients choose an occasional maintenance session. The decision is made with your doctor after your final assessment.
When will I see a difference?
Some people notice a change after two or three sessions, but the main improvement usually becomes clearer a few weeks to months after the course ends. Taking photos in consistent lighting and at the same angle helps you track progress. Results vary by individual.
