As mentioned above, some individual are not candidates for CoolSculpting due to medical issues or simply there is too much fat to remove with cryolipolysis.
You will see multiple individuals marketing "cryolipolysis" but they are using poorly built machines often coming out of Chine that simply do not work. Make sure that you are only going to a clinic with the ONLY FDA approved cryolipolysis treatments. Do NOT fall for it and ask to see the actual machine they will be using.
There are other options out there such as radiofrequency which uses radiofrequency to produce heat in the fat tissue essentially making the fat cells "pop". There are some effective units on the market that are FDA approved.
There are lasers being sold that are supposed to remove fat through the skin also using heat while using cooling to protect your skin. I do not have direct exposure to these procedures but I have heard that they are limited in their results.
Injectables have even been used for destruction of fat. The most common one is Kybella. It is only good for small areas such as the fat under the chin. It has fallen tot he wayside secondary to the cost as well as the need for multiple sessions which cause itching, bruising, swelling and inflammation that can last a couple of weeks.
Surgical intervention is also always an option. This can range from liposuction to surgical interventions such as a tummy tuck or even gastric bypass.
