Can CoolSculpting be given for 30 to 45 min instead of 1 hour? Will the results be the same? How often can I give in other area?

CoolSculpting cannot be done in 30-45 minutes.  The treatments are specifically designed to last 60-75 minutes per cycle.  My practice has two machines, so we can do DualSculpting, which does reduce the overall treatment time, but each individual cycle is still 60-75 minutes.  Shorter treatment times mean undertreatment and less results.

For the traditional suction applicators, a CoolSculpting treatment will take one hour.  This is the amount of time needed to effectively cool the treated area to therapeutic temperature and induce the programmed cell death of the fat cells.  The new flat applicator takes an hour and 15 minutes for treatment (with the flat applicators, the tissue is battling against the heat of the underlying tissue, so it takes more time for the tissue to reach the therapeutic temperature).If you are seeing a provider who suggests a shorter treatment time, I would ensure they are using the Zeltiq branded CoolSculpting machine.  Typically, if the treatment time is not an hour or 1 hour and 15 minutes, the office is using a "knockoff device" that is not FDA approved.
