Are certain areas/body compositions more responsive to Coolsculpting than others? (photos)

The areas that are most responsive to CoolSculpting are generally the areas that have the most amount of fat.  Between the three areas (calves, inner thighs, outer thighs) you mentioned, I would say usually the inner thighs would have the most amount of fat and thus would see the most change from a CoolSculpting treatment.  The calves generally do not have much fat and the outer thighs can vary.  

Yes, there is an art to CoolSculpting,
and much of it is in deciding which areas can best be treated. It is difficult
to assess completely from your photos which area is best, but it appears that
either the inner thighs or outer thighs should be treated first. I recommend
you choose the area that is most bothersome to start with. A different type of
treatment head is used for each of these 2 areas, and more than 1 treatment may
be necessary to achieve optimal results. Good luck in your decision.

In my opinion, there are two considerations as to the areas that are best to treat with Coolsculpting. Number one it is the amount fat. Number 2 is the type or density of the fat. Area with the largest amount of will do better, most likely because the ratio of fat to fibrous tissue is higher. It is my opinion that areas with firm fat do not do as well. Fibrous tissue predominates and does not respond sufficiently to the cool sculpting procedure. Often a second procedure cycle is recommended in the same area. Seek a  doctor with experience in cool sculpting and one who will show you pictures. Hope this helps. Good luck.
