I tried InMode because it was 125,000 won on Goddess Ticket.
I don't have much fat around my chin, so I didn't really feel a major effect, but my girlfriend seemed to say it was effective for her double chin area, so we went to get it once more.
My girlfriend said it hurt a little, but for me, maybe because the anesthesia worked well, it didn't hurt. The bruising was also light enough to disappear in about two days.
The price isn't exactly cheap, so I'll have to think more about whether to go again.
Still, it was nice that the director also did the consultation and kindly treated the areas I wanted accurately.
