Cryo T Shock vs CoolSculpting
Cryo T-Shock has no published study and no FDA clearance for fat reduction that could be found. It is a hand-held probe a practitioner moves over your skin, alternating warm and cold. CoolSculpting is the one with measured results, and they are small. It is a cup that holds a fold of fat at a set cold temperature for a set time, and the fat layer under it thins by about a fifth. Neither one is a weight-loss treatment.

The differences that matter
What you actually do
Cryo T-Shock
A probe moved over the skin
A practitioner passes a hand-held probe over the area, switching between warm and cold. It is sold as a course of several sessions, on the clinic's own terms. The maker posts no instructions for use.
CoolSculpting
A cup that holds a fold of fat cold
A cup draws a fold of tissue in by suction. It then holds that fold at a target temperature for a set time. In one review of 18,203 cycles, the median was 4 cycles and 1 session per person.
What you can expect to see
Cryo T-Shock
Not established
No study of this device has been published, so nothing has been measured. People say it is comfortable, and warm-and-cold rather than sharply cold. That describes the experience, not a result.
CoolSculpting
A thinner fat layer in one pocket
FDA's pooled review of 4,792 cryolipolysis treatments found the fat layer dropped 21%, or 3.9 mm. Study averages ran from 10% to 26%. It works on a defined, pinchable pocket.

CoolSculpting
What it will not do
Cryo T-Shock
No measured effect on fat
Nobody has measured what temperature the fat under the probe reaches, or for how long. With a probe moved by hand, the exposure depends on the operator.
CoolSculpting
Not for loose skin or cellulite
It is poor at loose skin, at cellulite, and at anything spread out.
How long before you see anything
Cryo T-Shock
Not known
There is no studied protocol, so there is nothing to compare a clinic's package against.
CoolSculpting
Over the following months
The cold inflames the fat lobules. The cells die over days, and the body clears them over the following months.
The downside
Cryo T-Shock
No safety record either way
Clinics describe no downtime. No safety data has been published for this device, so there is no record of its side effects. No reports is not the same as no risk.
CoolSculpting
Numb, firm and often sore
Nothing to see, but the area is numb, firm and often sore. A review of 554 procedures found that pain arriving a few days later was not uncommon, and it lasted 3 to 11 days. Numbness lasts longest. In one study, 4 of 30 patients still had it past 12 weeks.
Cost
Cryo T-Shock
Sold as a course, on clinic terms
Sold as a package of sessions, priced by the clinic.
CoolSculpting
Priced per cycle, not per session
Most people have more than one cycle. So ask for the price of the whole area, not the price of one cycle.
The at-home or drugstore version
Cryo T-Shock
Strap-on cold wraps
Gel wraps and belts are sold for freezing fat at home. A gel pack starts warming the moment you put it on, so nothing is held at a set temperature.
CoolSculpting
Not a cheaper version of the same thing
CoolSculpting holds a fold of fat still against a cooled plate, at a set temperature, for a set number of minutes. A wrap does neither. It is a different thing wearing the same name.
Who tends to be happy with it
Cryo T-Shock
- Best for - Someone who wants a comfortable body treatment, and is spending with that in mind.
- The mindset - What it does to fat has not been measured. Judge it on how you feel, not on a promised percentage.
CoolSculpting
- Best for - Someone near a stable weight, with a defined bulge in a cleared area and fairly firm skin over it.
- The mindset - Small, slow, and documented well enough that you can read what was measured.
The lump that can appear months later
Cryo T-Shock
Cryolipolysis can leave a firm lump where the fat ends up bigger than it was. It is called paradoxical adipose hyperplasia. It is usually painless, and shows up two to six months after treatment. It does not clear up by itself, and correction is surgery. How often it happens is not settled: published numbers are far apart.
Before you book
Cryo T-Shock
Say if you have cryoglobulinaemia, cold agglutinin disease or paroxysmal cold haemoglobinuria. In these blood disorders, cold destroys red blood cells. All three rule out CoolSculpting completely. That logic does not stop applying because a different machine is being used.
The fine print
Cryo T-Shock
No FDA clearance for fat reduction could be found for Cryo T-Shock. The FDA's 510(k) database returns nothing under the device name Cryo T-Shock or the applicant name Pagani, and neither does the registration and listing database. That is not a finding that the device does nothing. It means nobody has shown the FDA that it is equivalent to something already cleared for fat reduction. The result is that there is no labelling: no cleared body areas, no agreed temperature or duration, and no listed reasons to avoid it. No published clinical study of the device could be located either. Cryolipolysis has a large published record, but it was built on other machines, at documented temperatures and durations.
CoolSculpting
CoolSculpting's paperwork is the opposite of thin. Its FDA category was created for it by a De Novo authorisation, DEN090002, decided 24 August 2010, covering the flanks alone. Every body area since has been added by a separate 510(k) against the company's own earlier clearance, from the abdomen in 2012 through to K233732 on 12 September 2024. CoolSculpting Elite is K212707, cleared 5 November 2021. The device came from Zeltiq and is marketed by Allergan.
Common questions
Questions Patients Ask
Is Cryo T-Shock FDA cleared?
No clearance for fat reduction could be found for it. The FDA 510(k) database returns nothing under the device name Cryo T-Shock and nothing under the applicant name Pagani, and the device registration and listing database returns nothing under either name. Those are the two names the product is usually sold under; a US importer using a different corporate name would not show up in those searches.
Does that mean a clinic is breaking the law by using it?
Not in itself. FDA regulates what manufacturers claim about devices, not how clinicians practise. Where FDA has acted in this area, it has been against makers marketing uncleared fat-freezing hardware with claims like "eliminate fat cells" - the claim is what creates the requirement for clearance.
Is Cryo T-Shock the same thing as CoolSculpting?
No. CoolSculpting holds a fold of tissue inside a vacuum cup at a controlled temperature for a set number of minutes. Cryo T-Shock is a handheld probe moved over the skin, alternating warm and cold. Those are different exposures, and only one of them has published data on what it does to fat.
Does Cryo T-Shock work?
No published clinical study of it exists, so there is no honest answer beyond that. Cryolipolysis as a technology has real published data, but it was generated on other machines at documented temperatures for documented durations, and it does not automatically transfer to a different device.
How much fat does CoolSculpting actually remove?
It removes none directly - it injures fat cells and the body clears them over months. FDA's pooled review of 4,792 treatments put the mean reduction in fat-layer thickness at 20.6% by ultrasound, with study means ranging from 10.3% to 25.5%; an independent randomised trial measured about 14%. That is a percentage of the thickness of a pinched fat layer at one point, not of your body fat or your weight.
Will either one make me lose weight?
No. FDA states that non-invasive body contouring "will not result in weight loss", and CoolSculpting's maker says its procedure is not a weight-loss treatment. A pooled analysis of cryolipolysis studies found no significant weight change at all.
What should I ask before booking a cold body treatment?
The device name and manufacturer, its FDA clearance number if it has one, what body areas that clearance names, what temperature and duration will be used, and who handles it if something goes wrong. A clinic that can answer all five is telling you something useful either way.
Safety to keep in mind
Neither one is a weight-loss treatment. FDA says non-invasive body contouring "will not result in weight loss", and CoolSculpting's maker says its procedure "is not a treatment for weight loss".
Ask which device, made by whom, and what its FDA clearance number is. A clinic offering a cold body treatment may be running any of several machines, and they are not interchangeable. Registering a facility and clearing a device for a claim are different things. Only clearance names what the device is for. If no number is offered, that is your answer.
Mention a further list of conditions. Cold urticaria, Raynaud's disease, pernio or chilblains. Poor circulation or reduced feeling in the area. Bleeding disorders or blood thinners. Recent surgery or scarring. A pacemaker. Any hernia near the treatment site.
It does not mean anything unlawful is happening in the room. FDA regulates what manufacturers claim, not the practice of medicine.
Its cleared use is cold-assisted lipolysis - breakdown of fat - in named areas. Upper arm, bra fat, back fat, banana roll, thigh, abdomen and flank, in people with a body mass index of 30 or less. Under the chin and jawline are cleared separately, up to 46.2.
A 510(k) clearance is not proof that a device works. It is a finding that a device is much the same as one already on the market. The main test in most of these clearances was a photo test: blinded reviewers had to pick the "before" photograph out of a pair. In the under-chin study of 60 people, run by the manufacturer, the rate was 91%, against a pre-set bar of 80%.
What clearance gives you is text. Named body areas, a body mass index ceiling, a stated temperature and cycle time, and a published list of reasons not to have it. When there is no clearance, none of that exists.
