Long-term Effects of Coolsculpting?

I'm seriously considering getting Coolsculpting done on my love handles and stomach. I've read up on it, but can someone explain to me why it only damages the fat cells and nothing else? And also, does it ever come out "lumpy?" I'm worried about long-term side effects. Also, are the results more dramatic or thinner people or those with more weight to remove? Thanks :)

Long Term Effects of CoolSculpting?

To date there are no long term negative effects of CoolSculpting.The reason it only damages fat cells is that fat cells will freeze at higher temperature than other tissues. The reason the other tissues such as skin, nerves and blood vessels are not frozen at these same temperatures are that they are water based.   The device carefully controls the cooling process so that the temperatures achieved are such that the only the fat will freeze but are above the freezing point of other tissues inside the applicator. Regarding your second question, CoolSculpting gives a very NATURAL looking reduction without issues of lumpiness nor hanging excess skin. Finally, the ideal patient is the one who is close to their ideal weight with moderate to small bulges.  However, that is not to say that the procedure does not work in larger individuals.  As with all procedures proper expectations are critical.  I have treated individuals who are less than ideal and they have been extemely gratified by their results.  One does have to ensure that they understand that complete elimination of their bulge will not happen and if desired multiple procedures can be performed for additional fat reduction.  Having accepted this, they are more than thrilled to produce undeniable results with one treatment that does not require any surgery, needles, anesthesia nor downtime!

Cool Sculpting is only 20 to 25% effective.

One of the problems with Cool Sculpting is that it is only 20 to 25% effective and often struggles to achieve an artful beautiful result.

CoolSculpting Long Term Effects

CoolSculpting was developed by scientists at Harvard University. This unique, FDA-cleared and patented procedure uses a targeted cooling process that selectively targets and kills the fat cells underneath the skin, literally freezing them to the point of elimination. Only fat cells are frozen, leaving your healthy skin cells intact. The crystalized fat cells gradually die off and then are naturally eliminated from your body. Using a process called Cryolipolysis, it targets ONLY fat cells, which is why the surrounding tissue is not damaged. In the weeks and months following the treatment, the remaining fat cells condense thus reducing the fat layer. CoolSculpting is completely non-surgical, so typically you can return to normal activities immediately. Some patients experience redness, minor bruising, tingling, numbness and /or discomfort in the treated area which can last several weeks, but these are transient and will resolve. Patients typically return to their normal routine after the session is over. Generally, the treatment works best on individuals who have a bit of 'stubborn' fat that is resistant to diet or exercise and is not suited for individuals with a lot of weight to lose.

Long-term Effects of Coolsculpting?

Cool sculpting selectively damages the fat cells and spares the overlying skin based upon the cooling temperature and length of treatment. The machine settings are science based and approved by the FDA. We have seen no cases of lumpiness in areas treated nor any long term side effects. The results are more dramatic if you have smaller areas to treat and are otherwise fit. See a board certified plastic surgeon for a consultation and treatment plan.

Lasting results for unwanted stubborn fat

Zeltiq (CoolSculpting) provides a non-invasive approach to decreasing that unwanted stubborn fat that we just can't get rid of. It does not provide the same results as liposuction but it also is not invasive and has no downtime.

Safety & Long Term Effects of CoolSculpting

A.  When it comes to reading reviews and comments about CoolSculpting online you should factor in a number of variables. 
1.  Who is performing the treatment.  Skill, experience, and esthetic eye all make a big difference.  There is a lot more than just applying the applicator and letting it go to work.  There is a lot of treatment planning, mapping, and following results.  Areas may need to be treated again. 
2.  There are counterfeit CoolSculpting machines sold and used by many of the practices offering CoolSculpting in the U.S.  Why?  Because it costs much less.  Results are unpredictable, inferior, and often times result in complications.


B.  How it works
1.  CoolSculpting freezes fat cells causing apoptosis, slow cell death.  The fat leaks out of the cells and gets excreted from the body.  This effect is permanent.  Studies have shown that this doesn't damage surrounding non fat cells such as skin, muscle, and nerves.
2.  Lumpiness:  this is rarely seen when the procedure is performed properly.  If gaps are left between the applicator placement, you could get an area that bulges.  Treating over that untreated area will leave a smooth result.  The key is to have some overlap in the treatment areas to avoid this from happening.

C.  Who is a better candidate, skinny or heavier people?
1.  Heavier patients:  Results are quite dramatic and can come close to liposuction results especially when second treatments are performed over the same area.  You even get some skin tightening much like in our SmartLipo patients
2.  Skinnier patients.  We see great results.  They typically have trouble areas they cant lose with exercise such as love handles in men.  Losing those extra 3 to 5 pounds often creates a gaunt facial appearance- the face pays the price.  CoolSculpting can finish the job so that excessive weight loss and dieting is not required in fit people.

CoolSculpting Is Excellent for the Right Candidate

Good questions. CoolSculpting works because the fat freezes at a higher temperature than other tissues. The device carefully controls the temperature and the areas damaged. The amount of fat, elasticity of the skin, and, yes, skill of the operator all have an effect on the result. Expect about 25% of fat to be diminished with each treatment, so the larger the fat deposit, the greater likelihood several cycles may be required to achieve the best result. It is a great option for the right candidate, so discussing it with a surgeon who does all forms of body contouring should give you an educated opinion of your options. Good luck!

Coolsculpting effects

Coolsculpting works on fat preferentially because those cells are more sensitive to cold. The device controls the process and temperature carefully giving a uniform result. I have not seen contour irregularities (lumpiness) in any of my patients to date.

Long-term Effects of Coolsculpting?

CoolSculpting has been around for several years now. Its effects last — but it is a two-way street. You must use diet and exercise to maintain the effects; otherwise there is always a risk for weight gain and new fat formation if you decide not to take care of yourself.

CoolSculpting to reduce fat

CoolSculpting is a very effective way to reduce some excess unwanted fat in some areas. It can be used just about anywhere below the neck. The important thing when having CoolSculpting is choosing the right applicator (attachment for the machine) for the areas to be treated. The key is to make the fat super cold which damages the fat cells. The other cells in the same area (skin, muscle, etc.) are not nearly as sensitive to the cold. If the right applicator is used and you're a good candidate for the treatment you should expect smooth, even, and effective results. The results are more based upon the nature of the excess fat than the amount of it. I have seen good results from thin patients and others who have more excess fat. Have a discussion with a few docs that offer CoolSculpting, it's not a one size fits all procedure. 

I hope this helps!
