CoolSculpting Vs. Zerona

Zeltiq CoolSculpting and Zerona were both FDA-approved at the same time, and both involve non-invasive fat removal. Is it fair to lump the two procedures together and compare them? Are good candidates for one treatment necessarily good candidates for the other?

CoolSculpting is better than Zerona

Things to consider:

• CoolSculpting is the first  device cleared for the fat reduction!
– Zerona is cleared for non-invasive body contouring (circumferential reduction) and NOT for fat reduction. 
• CoolSculpting selectively & reliably eliminates fat in TARGETED problem areas
– Zerona cannot target where the reduction will occur.  It can only claim total contouring & circumference reduction (no telling where the 3.5 inches will come from)
• CoolSculpting KILLS the targeted fat cells
– Zerona cannot claim fat-cell elimination. The fat cells are diminished in size but do remain in place. In fact, their own study claims that this change may be temporary and more studies are necessary. In fact, what you see 2 weeks post treatment in their study are test patients starting to gain their fat back!
• CoolSculpting has no post treatment requirements, diet or exercise regiments.  CoolSculpting kills the fat cell!
-Zerona requires patients must be willing to maintain regular diet & exercise during treatment
-Zerona  Patients must give up caffeine & alcohol for 1 month & must exercise
– 2 weeks before treatment & 2 weeks during treatment
– Exercise 30 minutes a day
– Drink 8 to 10 glasses of water each day

Patient Candidacy for Lasers Targeting Fat

Dear Sharon,

I suggest all potential patients and parties interested in facial plastic surgery to consult a board certified facial plastic surgeon to receive the highest quality knowledge, treatment, care and skill available. A consultation provides you the opportunity to relay your concerns and desired outcome to the surgeon while the surgeon can assess your health profile and discuss his/her pertinent advice. It is in the consultation that patients realize if they are good candidates for one of the lasers that targets fat.

Here at the Clevens Center, we tend to consider a patient's candidacy for SculpSure before other fat trimming techniques because SculpSure is the best procedure out there. In fact, SculpSure is the only FDA-approved laser to provide the quickest treatment (25-minutes) and easiest recovery (none). Patients complete the treatment and walk out of our office ready to resume their ordinary activities.

CoolSculpting or Zerona?

In my opinion, CoolSculpting has proven to be better than Zerona.
The Zerona is cleared for non invasive body contouring whereas the CoolSculpting is cleared for non invasive fat reduction.  So if you are looking to reduce a specific area, CoolSculpting is the better choice.

Coolsculpting versus Zerona

Hands down, I would recommend Coolsculpting over the Zerona system.  I have seen patients treated with Zerona, and the biggest complaint is the transient nature of the result from Zerona, and the need for multiple treatments.  With Coolsculpting, there is a permanent reduction in the number of fat cells in the treated area and the patient satisfaction is much greater.

Completely different techniques

The two devices have completely different mechanisms of action.  Coolsculpting utilizes freezing temparature to reduce the fatty bulges without damaging the skin, and Zerona uses phototherapy/light energy to reduce the fat.  I am a big proponant of phototherapy overall, but for fatty bulge reduction, Coolsculpting has much more literature behind it as well as almost 2 million treatment cycles performed to date, with high patient satsifaction.

CoolSculpting vs. Zerona: How Do They Compare?

Though CoolSculpting by Zeltiq and Zerona may sound somewhat similar and are often confused for one another, they are very different in the way that they work and their results. CoolSculpting is the only FDA approved treatment that kills the fat cells by freezing them to the point of elimination. These fat cells are killed permanently and do not return. There are no dietary restrictions or exercise programs that are indicated with CoolSculpting, however, those people who maintain a healthy diet and an active lifestyle will get the best out of their results.

Zerona, on the other hand, uses cold laser to disrupt fat cells. The content of the fat cells leak out, but the fat cell remains alive and is not killed. So, the fat cells treated with Zerona can always grow back to their original size after the treatment. That's why it is recommended to be used in conjunction with a regular diet and exercise regimen. While Zerona is FDA approved, this approval is for non-invasive body contouring and not for fat reduction.

We chose CoolSculpting over Zerona as there was overwhelming evidence that CoolSculpting is effective with long-lasting results. The same could not be said for Zerona. In our practice we have used CoolSculpting to treat many patients who previously had Zerona and did not see any results. They have all been very please with their results after just one CoolSculpting treatment!

Coolsculpting is much more effective!

The main difference is the removal of fat cells. The Zerona perforates fat cells and the cells begin to leak. The lipids released from the cells are eliminated through the lymphatic system. The gradual leaking of the cells leads to fat cell shrinkage but the fat cells will remain active in the body. Coolsculpting freezes and destroys fat cells. Fat cells treated with Coolsculpting die off completely. The body gradually eliminates the cells. Once those fat cells have been removed, they are gone permanently.

Coolsculpting versus Zerona

Fat reduction or contouring is a sought after procedure and there are several options available.  Both technologies have been FDA approved but for different reasons and with different indications.

Coolsculpting uses cold to produce cryolipolysis of the fat cells in specific areas of the body.  It is a permanent reduction of the fat cells but it is limited to certain areas of the body.  The handpiece has to be able to grab onto the tissue and pull it into the handpiece to cool it between two plates.  The device works well for areas of the body that have some laxity and can fit into the handpiece to cool.

Zerona was approved for non-invasive body contouring and works to change the membrane of the fat cell to shrink it.  Combined with diet and exercise there can be a contouring effect over the body.

Coolsculpting By Zeltiq is Effective Fat Elimination

Sharon Coolsculpting has many clinical studies and happy patients ( including my staff) proving its efficacy in the real world. There is no doubt that I can make more of a change with Aqualipo or Smartlipo but many patients prefer not to go to the operating room or to have down time. Coolsculpting can eliminate targeted fat by greater than 20%. the procedure takes one hour per targeted area. There are no post operative protocols to follow for diet and exercise. the best candidates are one within 20 pounds of their BMI

Zerona cannot target exact areas. It does not eliminate but shrink cells. It relies on diet and exercise.
