I want to check if deep cheek fat is the problem.

It feels like the area under my chin and the inner part of my cheeks just won't go away. Even though I've lost weight overall, my facial contours seem to remain the same, so I'm wondering if this isn't just fat but a problem with deep cheek fat.

I looked it up and heard that deep cheek fat is located in the deep layers of the skin, so it is difficult to lose through general dieting or exercise. I am wondering if this is true. I would also like to ask what kind of procedure is used when deep cheek fat makes the face look big or saggy, and whether the results look natural after the treatment. I am writing this post because I would like to understand the concepts beforehand before my consultation.
