Contour injection, facial fat dissolving injection

What kind of contour injection should I get?

I want to lose my cheek fat and double chin fat, but I don't know which one to get. They say that it's good to get square jaw botox when you bite down on the muscle, but I'm not sure if I can make a good decision. ㅠㅠ If I visit, will you give me a consultation before the procedure?
