Worried about facial swelling and a double chin? Will InMode be effective?

I have a body type where even a slight weight gain causes my face to swell immediately and a double chin to form, making me look grumpy and sagging skin, which is a major concern for me. In particular, my jawline has become indistinct and my face looks bigger, which has lowered my confidence. I've heard InMode mentioned frequently among lifting procedures lately, and I'm curious about its actual effectiveness. I became interested because I heard it is beneficial for defining the jawline and improving skin elasticity. I also heard that it helps reduce swelling due to its fat-dissolving effects; would getting the treatment before my summer vacation make me look much better in photos? Since I can't exercise due to the heat and lack the time for proper care, I'm wondering if there is a way to improve this, even if it's just a simple procedure. If anyone has experience with InMode, I would appreciate your advice regarding its effectiveness and how long the results last.
