Which is a good option for the square jaw procedure, which is a complex issue?

When I was young, I had a slender face, but as my crooked teeth came in and I didn't have them removed quickly, I developed malocclusion.

Since then, my face shape has changed to a square.

My face isn't very big, but because my jawline is angular, it becomes a source of insecurity.

I haven't thought about surgery because I'm afraid of it and it costs a lot.

These days, there are so many types of injections, which procedure is good?
