Cryolipolysis is performed by a plastic surgeon, dermatologist or other physician in the office setting. No anesthesia or sedation is required for the cryolipolysis procedure because it is non invasive and relatively painless.
A small area of fat tissue is gently drawn into a suction cup, of sorts. 
The cryolipolysis device applies cold (which is really removing heat from the tissue) to the treated area for a period of several minutes.
The cryolipolysis device is then moved to each treatment area sequentially. Since there are no incisions, anesthesia or sedation, patients can resume normal daily activities immediately after cryolipolysis.
What Areas of the Body Can Be Treated with Cryolipolysis?
Cryolipolysis is most commonly used to treat localized fat deposits that are resistant to diet and exercise. These include the lower abdomen, flanks (love handles), upper arms, thighs, back fat, and the submental area (double chin).
Treatments are highly customizable, and many cosmetic surgeons will develop a treatment plan that targets multiple zones over a series of sessions. Because it’s non-invasive and requires no downtime, cryolipolysis is often chosen by patients looking for subtle body contouring without the risks or recovery associated with liposuction surgery.
Who is Eligible for Cryolipolysis?
The technology is fairly new but appears to be quite safe in limited laboratory and clinical studies. It does seem that the best results are achieved by patients that are already fit and in good health. Also, cryolipolysis is better suited to treating small target areas like “love handles” rather than large areas of fat like the entire lower abdomen.
How Long Do Cryolipolysis Results Last?
One of the most common questions patients ask is how long the fat loss from cryolipolysis will last. The good news is that once the fat cells are destroyed and naturally eliminated by the body, they do not regenerate.
This makes cryolipolysis a permanent fat reduction treatment, assuming the patient maintains a healthy diet and lifestyle. It’s important to note, however, that weight gain can cause the remaining fat cells in untreated areas to expand.
For this reason, cryolipolysis is ideal for patients who are committed to maintaining their results with ongoing physical activity and smart nutrition choices.
Are There Side Effects from Cryolipolysis?
Patients that have been treated by this skin cooling device do report redness over the treated area which goes away after a few hours. The suction may cause minor bruising over the treated area.
Also, since the application of cold also slows down the cellular processes of nerves and nerve endings, patients may experience some temporary numbness and tingling in the skin over the treated fat layers.
The Science Behind Cryolipolysis
The term cryolipolysis can be divided into cryo- which is cold or freezing, lipo, which means fat and the suffix –lysis, which means to break apart. Therefore when combined, cryolipolysis means the destruction of fat cells by freezing or cooling.
While the exact mechanism of action is still unclear, the current understanding is that when fat cells are exposed to cold, they undergo necrosis (cell death) and/or apoptosis (genetically programmed cell death; like a self-destruct program for the cell).
The process of cryolipolysis is considered to be very similar to cold panniculitis in which fat cells die in response to cold. In any case, the fat cells break apart and die within days to weeks after cryolipolysis.
Is Cryolipolysis Approved by the FDA?
The company that is pioneering cryolipolysis is called Zeltiq Aesthetics. While the company’s cryolipolysis devices and technology have been approved for fat reducing applications in Canada and the European Union, it has not yet earned FDA approval for this application in the United States.
Zeltiq does have clearance from the FDA for the use of their cryolipolysis devices for skin-cooling applications. Zeltiq Aesthetics is currently seeking FDA approval for their devices to be used in fat reduction or fat removal applications.
Zeltiq hold patents protecting the concept of cryolipolysis and related technologies. Studies up until this point seem to indicate that cryolipolysis is both safe and effective in fat reduction.
Is Cryolipolysis Right for You?
While cryolipolysis offers many advantages over traditional fat removal procedures, it’s not ideal for everyone. The best candidates are individuals who are near their ideal weight but struggle with pockets of stubborn fat. It is not a weight loss procedure and should not be seen as an alternative to bariatric surgery or lifestyle change.
During your consultation, a qualified cosmetic surgeon or dermatologist will evaluate your goals, health history, and body composition to determine if cryolipolysis is the most effective solution for your needs. Always seek out a licensed provider with experience using FDA-cleared devices like CoolSculpting to ensure safety and results.
