Do you know how long InMode lasts?

I practically lived on hotteok and bungeoppang all winter, so while my weight stayed the same, my face got so fat that I ended up with a total double chin ㅠㅠ I was shocked to see my chin was double-layered after seeing a photo my friend took from below, so I'm planning to sign up for a lift right away lol. It's definitely the way to go when it comes to destroying unnecessary fat. Inmode I heard this is the most famous one; if someone with a severe double chin like me gets this, will their jawline tighten and become slim? I saw reviews saying it gets really hot and painful due to the radio frequency heat, so I'm getting scared right away. Also, I heard the bruising on the face lasts for a few days, so I'm planning to get this over the weekend. Inmode I'm also curious if it can be completely covered up with makeup when I go to work on Monday! I'm wondering if getting it just once definitely creates a V-line, and Inmode I'd appreciate it if those of you who have experience could leave a comment on how long the effects last!
