I have tried CoolSculpting, kybella, and PCDC injections in my upper arms to lose 1”. All were done more than once and none of them worked. Why? I have 23% bmi my arms are 12.5”. It’s definitely fat. Short of lipo I don’t understand why it hasn’t worked and why my arms are so resistent. I have had lipodissolve in other parts of my body and it worked.
