I had fat freezing done and it hasn't worked. I had it done for 30 minutes. Is this normal? (photos)

What is not normal is your treatment time.  Even with the new "cup" heads a normal treatment for an area is about 35 min. and unless they are using 2 machines, that is only for one cycle or area of treatment.
We usually recommend a minimum of 2 cycles per area and from what I see in the pictures, I would recommend 4 cycles for your abdomen which would be a total of 8 cycles at 2 sessions, one month apart.

Good luck

30 minutes is not a typical treatment. Zeltiq deems any treatment less than 50 minutes to not be a complete coolsculpting treatment. Make sure that the center is listed on the coolsculpting.com website as an approving coolsculpting center.
