Inquiry about contouring fat-destroying injections for stubborn double chin fat that won't go away even with dieting!

Hello! I worked hard on my summer diet and managed to lose overall weight, but strangely enough, the double chin fat bulging under my jaw just won't go away. Even when I just tilt my head down slightly, my chin fat folds thickly, and the boundary between my jaw and neck becomes blurred. It stresses me out because I look so bulky every time I take a side selfie. Home gua sha treatments seem to just provide irritation, so I'm thinking of getting help from injections or contouring treatments to effectively reduce the sub-chin fat! Has anyone seen their double chin subside after getting the CutSlin Injection or contouring diet injections at Maypure? Please share your experiences regarding pain, bruising, swelling, and downtime!
