I'm worried about my fat face

The facial bones are slim, but there is a lot of fat under the cheeks, so the face looks big and slightly peanut-shaped. Even when I consulted a dermatologist, they said that the outline was very small, but it was buried in the skin and couldn't be seen ㅜㅜ
 I was really worried, so
 I've used Inmode twice so far (paid for 3 times). I received Botox contouring injections like this, but
 it doesn't seem to have any effect.
 Is diet the only thing left??
 I'm not skinny, but I'm within normal weight. I'm
 still 21 years old, but my face shape is so stressful that even though I got swollen part-time job, it doesn't work... It's bittersweet.
