Onda vs CoolSculpting in Seoul

What are Onda and CoolSculpting?

Onda is a device that uses 2.45 GHz microwave energy, called Coolwaves, for fat reduction, skin tightening and cellulite. In Korea it is popular as a face and jawline lifting treatment. CoolSculpting is a cryolipolysis device that cools fat to a temperature that damages fat cells but not skin.

What is the key difference?

Onda's microwaves are absorbed mainly by fat, heating it to damage fat cells and stimulate collagen in the deeper skin, while the surface is cooled. CoolSculpting holds a fold of fat in an applicator and cools it for a set time, and the damaged fat cells are cleared by the body over weeks. The key difference is heat versus cold: Onda also tightens skin, while CoolSculpting focuses on fat only.

Which one should you choose?

Choose Onda if you want to slim the lower face or jawline and tighten skin
Choose Onda if you have mild fat with some looseness
Choose CoolSculpting if you have a clear, pinchable fat bulge on the body
Choose CoolSculpting if you want one area treated with no needles and little discomfort
Choose either only if you are near your stable, target weight
