InMode FX vs ONDA for a double chin

InMode FX is cheaper and faster (10 minutes, from KRW 59,000) but leaves suction marks for 3–7 days, so it is a last-day treatment; ONDA has no marks, costs more, and suits people who need to look normal the next day.

InMode (FX / Forma)

People in their 20s to 40s with a double chin, soft jowls, or mild cheek fullness who want a sharper jawline, and anyone who wants a quick firming boost before an event.

ONDA Coolwaves

ONDA is an Italian (DEKA) microwave device that reduces fat and tightens skin at the same time. On the face it is used for a double chin and lower-face fullness; on the body it treats cellulite and localized fat.

People with a soft double chin or heavy lower face who want contouring with less pain than InMode FX, and body patients targeting thighs, abdomen, arms or flanks.
