The science of CoolSculpting
There is more to CoolSculpting been just the actual temperature at which the treatment is administered. The rate of cooling and other factors are also important. Over 1 million CoolSculpting cycles have been performed to date and this treatment remains one of the safest and most effective aesthetic options available today.
At What Temperature Does Fat Freeze?
Hi Sati. Fat freezes at 4 degrees celsius, which is 39.2 degrees fahrenheit. This is higher than the freezing point of water, blood, etc. Therefore, all your other cells are perfectly safe from damage during CoolSculpting. Hope this helps. Best of luck on your treatment.
Temperature of CoolSculpting
CoolSculpting works by cooling an area to reduce fat. The temperature that it achieves is just above the freezing point of water, so it does not freeze the non-fat cells.
The cooling panels get to -10 degrees Celsius. Coolsculpting is FDA approved and very safe.
Coolsculpting is an excellent form of non-invasive fat reduction for
the right patient. Some applicators take 1 or 2 hours but the new advantage
applicators take only 35 minutes and have significantly less risk for delayed
onset pain (especially in the abdomen). Results are seen at 2 months and
typically 1-3 treatments will be necessary on each area to achieve ideal
results. The number of treatments depends on the amount of fat there and the
patient's goals. There is not downtime and the results can be impressive
in the right patient. We also use the Zimmer Z-wave for improved patient
comfort and added results. The best candidates are those who are in pretty
good shape with areas of stubborn fat that won't go away no matter what.

The device is extremely
safe and works very consistently. Yes, you can freeze the skin – we did that in
one of the very first patients – but its protective mechanism allowed that
patient to heal without any problems and it has since been changed that it
can’t actually happen anymore. The problem is that many salon environments are
trying to mimic CoolSculpting’s efficacy with knock-off devices that do
not have the same safety. Be very careful what you are signing up for as many of
these salons are quite sneaky.
Science Behind CoolSculpting
During the treatment, the cooling panels get to -10 degrees Celsius, however the fat itself does not get down to -10 degrees. Monitoring of the treatment is based on a thermal extraction rate measured at the cooling panels and is defined as Cooling Intensity Factor. There is a Freeze Detect System which monitors heat extraction for safety. When the system sense that the skin might be reaching a point of freezing, treatment will stop automatically. None of the skin cells from the epidermis layer are affected by CoolSculpting.
Thanks for your question and thanks for doing your homework – this is always not the case with these types of procedures. As noted by some of the other experts who have answered this question, there are several built in mechanisms that have been built in to the device to minimize the risk of freezing any of the surrounding skin cells in the area and that we keep it specific for the fat cells in the applicator treatment site. As Dr. Kilmer noted, there are many other devices out there that claim to do the same as the Zeltiq device – and none of them have clearance in the US by the FDA although some have made their way into the US. The ultimate safety of these devices have not been fully determined so we would never recommend that any of these be used in this country at this time. Be smart and be careful and find a CoolSculpting provider that can best handle all of your concerns and answer the questions that you have.
