What is the difference between Mode and Forma, and which one would be better for slightly sagging cheeks?

Recently, I feel like my facial lines have become strangely dull, so I am looking into elasticity lifting procedures.

I heard that InMode is famous, so I looked it up and found that there are two modes: 'FORMA,' which uses high frequency and high-voltage current, and 'FX,' which is said to kill fat cells. I am curious about the exact differences between the two modes.

My cheeks aren't severely chubby right now, but when I smile or am still, they sag slightly, and the boundary between my cheek fat and jawline feels blurred. In this case, would FX, which burns fat, be better, or would Poma, which helps with skin tightening and collagen production, be more effective?

I would appreciate recommendations from those who have received treatment for similar concerns or from experts!
