Is cryolipolysis effective on muscular calves?

CoolSculpting is a great technology, but as a surgeon who does both a significant amount of CoolSculpting and liposuction, I would not recommend CoolSculpting for the lower legs. It is very likely to leave an indentation. Lower legs are best treated with liposuction by a surgeon experienced in lipo, as they can be very difficult to obtain a nice result on. I recommend seeing a board certified plastic surgeon to see if you are a candidate. Best of luck to you!

Unlikely. In all honesty, in your particular case, you need to be evaluated in person, to see exactly what your calves look like, how much fat is present, and to determine what your goals and expectations are. CoolSculpting employs cryolipolysis to remove fat, but is best intended for small localized areas of fat that are "pinchable". It does not sound like the various CS applicators would be able to be employed to effectively treat your calves. Depending on your body type, you might be a candidate for minimally invasive lipo of the calves, or potentially for treatment with various other non-invasive devices that could provide skin tightening or volume reduction. It would be best for you to be seen by an experienced cosmetic specialist, who has multiple treatment options available to meet your needs.

An exam would be needed to see exactly what you are describing.  CoolSculpting would not attach to the areas with suction. It is possible another treatment such as Thermi250 could help. I have done Kybella injections to help sculpt calves. This is expensive  because it takes far more product than your chin/submental but permanent.
