Would I be a good candidate for the double chin fat-destroying diet injection?

No matter how hard I exercise and control my diet, strangely enough, the fat pocket sticking out under my chin like a hard candy just won't go away. Whenever I tilt my head slightly, the boundary between my neck and chin blurs, making me look so bulky in photos. I'm considering getting a diet injection that targets the fat cells themselves, but I'm wondering if cases like mine, where people suffer from stubborn fat in specific areas, qualify for recommendations. Is the effectiveness of this diet injection certain—cleanly removing only the fat under the chin without worrying about steroid side effects or hollowing out the cheeks? I'm waiting for reviews from those who met the recommendation criteria for diet injections due to similar concerns and achieved a V-line face. !!!!!!!
