Quick answer
What is Onda body contouring?
Onda (DEKA) is a non-invasive body contouring system that uses 2.45 GHz microwaves, called Coolwaves, to heat the subcutaneous fat layer selectively while the skin surface is cooled. Heated fat cells are damaged and gradually cleared by the body, and the warmth also stimulates collagen in the overlying skin.
It is used in Seoul for localised fat on the abdomen, love handles, thighs and arms, for cellulite, and for mild skin laxity after weight loss. For the face and jawline, see Onda lifting.

FAQ
Onda body questions
Is Onda body contouring painful?
Most people feel deep warmth with brief hot spots. The handpiece cools the skin continuously, and no numbing is needed.
How is Onda different from fat-freezing?
Onda uses microwave heat rather than cold, and it can also tighten skin and improve cellulite. Both reduce fat gradually over weeks.
Which areas can be treated?
Common areas are the abdomen, flanks, thighs, upper arms and buttocks.
How long until I see results?
Changes begin after a few weeks and are clearest around 2–3 months after the final session.
Do foreigners pay more?
No. International patients pay the same price as local patients at Umi Clinic.
