How can i lose chin and belly fat only?

I’m not entirely fat, only my belly and chin are.

My belly isn’t ultra huge but the fat is still there, and it’s noticeable considering that my arms and legs are thin.

As for my chin…usually when I smile, the extra fat I have under my chin kinda blends with my jawline and makes me look even fatter than I am.

My belly and my chin area are the only parts not in proportion to my body and I hate it. How can i lose those extra fat?

For my chin area, what exercises work the best?
