People, struggling with stubborn fat deposits that do not respond to diet and exercise, resort to such body contouring procedures as CoolSculpting. Given that the procedure is non-surgical, it is imperative to understand its safety, effectiveness, and potential side effects in order to make informed choices. To help us understand the procedure better, THIP Media talked to a highly skilled Dermatologist, Cosmetologist, and Hair Transplant Surgeon Dr Ratnakar Shukla. He is the Founder and Director of Dermagenix in Gorakhpur. With an experience of more than a decade, Dr. Shukla has an extensive understanding of several dermatological conditions and their respective treatments.
Q: Will you consider CoolSculpting a medical procedure, or is it just an external beautification?
Dr Ratnakar Shukla: Cryolipolysis is a body sculpting technique based on the application of controlled cooling for localised fat reduction. Lipid‐rich adipocytes are more susceptible to the effects of cold than other cell types, and hence, Cryolipolysis can induce the apoptosis of adipocytes without causing significant damage to other local structures.
CoolSculpting (Cryolipolysis) is a non-surgical medical aesthetic procedure, and it requires FDA-approved equipment, proper patient selection, and trained personnel. Although non-invasive, it alters body tissues at a cellular level — making it a medical aesthetic procedure rather than a simple beauty treatment.
Q: If this is a medical procedure, why is it so widely practiced in salons and fitness centres instead of hospitals?
Dr Ratnakar Shukla: Currently, there is no strict enforcement of laws restricting the use of medical-grade devices like Cryolipolysis machines to qualified doctors or registered medical centres. As a result, salon owners and unqualified cosmetologists can easily buy or rent these machines and offer the procedure without any formal medical training. They often market it as a “simple fat-freezing treatment” rather than a medical procedure, which misleads the public into believing it is risk-free.
In reality, CoolSculpting requires proper patient selection, knowledge of anatomy, and management of complications, which only trained medical professionals possess. Offering such procedures in non-medical settings compromises patient safety, increases the chances of burns, uneven fat loss, paradoxical adipose hyperplasia, and other complications, and delays proper medical care when something goes wrong. This is why Cryolipolysis should be done only under medical supervision in certified clinics or hospitals. In India, CoolSculpting, or Cryolipolysis, is a medical aesthetic procedure, but it is still widely practised in salons and fitness centres due to a combination of weak regulation, commercialisation, and lack of public awareness.
Q: From a safety perspective, how reliable is CoolSculpting as a fat reduction treatment?
Dr Ratnakar Shukla: From a safety perspective, CoolSculpting (Cryolipolysis) is generally considered a safe and FDA-approved non-invasive fat reduction treatment when performed by qualified medical professionals in a proper clinical setup.
It works by regulating the cooling of fat cells without damaging the overlying skin. However, like any medical procedure, it is not risk-free. Common side effects may include temporary redness, numbness, bruising, or mild discomfort. Rare but serious complications, such as paradoxical adipose hyperplasia (PAH)—an abnormal increase in fat in the treated area—can occur. The reliability and safety of CoolSculpting depend heavily on:
- Proper patient selection (not everyone is an ideal candidate)
- Use of authentic, medical-grade equipment
- Trained medical supervision to handle complications
- Strict adherence to protocols
When done in unregulated places like salons or gyms by untrained people, the risk of burns, nerve injury, uneven fat loss, or untreated complications increases significantly. Therefore, for reliable and safe results, the procedure of CoolSculpting should always be done by qualified dermatologists or plastic surgeons in a certified clinic or hospital.
Q: Are there any specific health conditions that make CoolSculpting unsafe?
Dr Ratnakar Shukla: Yes, there are several specific health conditions that can make CoolSculpting (Cryolipolysis) unsafe or unsuitable. Since the procedure involves controlled cooling of fat tissue, any condition affecting the body’s response to cold or healing can increase the risk of complications. CoolSculpting is contraindicated or should be avoided in individuals with:
- Cold-related disorders, such as: Cryoglobulinemia, Cold agglutinin disease, Paroxysmal cold haemoglobinuria
- Poor circulation or nerve disorders, including: Peripheral neuropathy, Raynaud’s phenomenon (in severe cases)
- Skin or fat conditions: Open wounds, infections, eczema, or dermatitis in the treatment area
- Hernia near the target area
- Pregnancy or breastfeeding (not a treatment period)
- Individuals with unrealistic expectations or significant obesity (it’s a body contouring, not weight-loss procedure)
A thorough medical evaluation by a qualified dermatologist or plastic surgeon is essential before treatment to rule out these conditions and ensure patient safety.
Q: What kind of side effects can patients expect — both short-term and rare complications?
Dr Ratnakar Shukla: Patients undergoing CoolSculpting (Cryolipolysis) may experience a range of short-term and rare complications, depending on their skin sensitivity, body type, and whether the procedure is done in a qualified medical setting or not.
Common & Short-Term Side Effects (usually mild and temporary):
These are generally seen in the first few hours to days after the procedure:
- Redness and mild swelling at the treatment site
- Temporary numbness or tingling sensation
- Mild bruising
- Tenderness or slight discomfort
- Firmness or a “lumpy” feel in the treated area (usually resolves on its own)
- Mild itching as the area heals
These effects are expected and self-limiting when the procedure is performed correctly.
Rare but Serious Complications:
These are uncommon but require medical attention:
- Paradoxical Adipose Hyperplasia (PAH): an abnormal, firm enlargement of fat in the treated area weeks to months after the procedure.
- Frostbite or burns due to improper use of the device (more common in salons or with non-standard machines).
- Nerve injury or prolonged numbness, if tissues are overexposed to cold.
- Contour irregularities or uneven fat reduction, often due to poor technique.
- Infection or skin necrosis (very rare but serious if asepsis is not maintained).
While CoolSculpting is considered safe in trained medical hands, the risk of complications increases significantly when done by unqualified personnel or in salons without proper protocols. That’s why patient selection, authentic devices, and medical supervision are crucial for both safety and good results.
Q: How does CoolSculpting compare with surgical options like liposuction in terms of safety and results?
Dr Ratnakar Shukla: CoolSculpting is safer, less invasive, and requires no downtime but offers more modest results, whereas Liposuction is more invasive, with higher risks, but achieves greater and faster fat reduction in one go. The best choice depends on patient goals, medical fitness, and expectations and should be decided in consultation with a qualified dermatologist or plastic surgeon.
Q: Does it work equally well for males and females, or are outcomes different?
Dr Ratnakar Shukla: Women typically have softer, more evenly distributed subcutaneous fat, especially around the abdomen, thighs, hips, and arms. CoolSculpting often gives smoother contouring and more uniform results in these areas. Women generally seek treatment for shaping and toning rather than bulk fat removal, whereas men tend to have denser, more fibrous fat, particularly around the abdomen and flanks (love handles). The fat may be more resistant, so results can take longer or may require more sessions compared to women. Men are more likely to focus on targeting specific bulges rather than overall contouring. In short, CoolSculpting is effective for both males and females, but the number of sessions, speed of results, and treated areas may differ slightly due to physiological fat distribution differences.
Q: What scientific evidence or clinical studies support the effectiveness of CoolSculpting? Will the process be effective even on visceral fat?
Dr Ratnakar Shukla: The concept of Cryolipolysis was developed at Harvard University by Dr Dieter Manstein and Dr Rox Anderson. Their research (Lasers in Surgery and Medicine, 2008) showed that fat cells are more sensitive to cold than surrounding tissues. Controlled cooling can selectively destroy fat cells without harming skin or nerves.
Key Clinical Studies:
- Manstein et al., 2008: Found significant reduction in subcutaneous fat layer with controlled cooling.
- Dierickx et al., 2013 (Aesthetic Surgery Journal): Showed consistent fat layer reduction of 20–25% in treated areas, with stable results over months.
- Coleman et al., 2009: Demonstrated both efficacy and safety, with histological confirmation of fat cell apoptosis (natural cell death).
CoolSculpting is not effective on visceral fat. Visceral fat is the deep fat around internal organs, not the superficial fat layer under the skin. The cooling applicators only act on the subcutaneous layer, where they can target fat cells directly. Visceral fat can only be reduced through diet, exercise, or bariatric/metabolic interventions — not through Cryolipolysis. So, while CoolSculpting can give noticeable inch loss and body contouring, it does not reduce belly fat that lies beneath the muscles or inside the abdomen.
Q: How has technology improved CoolSculpting over the years? Has that advancement reached the Indian market yet?
Dr Ratnakar Shukla: The technology has improved over time; the shape, size and contour of applicators have been optimised; and larger cooling panels are used nowadays, so the device treats more fat tissue per session. In older machines, you treat one area at a time. Newer ones allow using two applicators simultaneously (on two areas), reducing treatment time. Because of improved applicators with more surface contact, treatments that used to take longer are now faster.
Some sessions are almost half the time, and simultaneously, more body areas can be covered, with more precise targeting. Nowadays, smaller/mini applicators are available for hard-to-reach or curved zones (chin, under-buttock, arms, etc.) and allow treating these areas more safely & comfortably. More comfortable suction design, faster numbing, less pinching discomfort. Improvements in cooling control and better contact with skin (less uneven cooling), which can reduce side effects and lead to a better patient experience – these advancements reached the Indian market too, but availability varies by clinic and city.
Even though the technology is more advanced, not all clinics have the latest machines, and also, training and expertise vary a lot. As with all medical/aesthetic procedures, safety and outcome reliability depend heavily on who is doing it, what equipment they use, and whether the clinic follows good standards.
Q: Does this act as a shortcut to reduce fat from the body? Are the effects sustainable?
Dr Ratnakar Shukla: No, CoolSculpting (Cryolipolysis) is not a shortcut to weight loss; the technique targets only localised subcutaneous fat (the pinchable fat under the skin), not visceral fat or overall body weight. It removes only 20–25% of fat in the treated area per session, which is useful for body contouring, not for weight reduction. It doesn’t address underlying factors like poor diet, lack of activity, or metabolic issues. Once fat cells are destroyed, they do not return, so results can be long-lasting. However, the remaining fat cells can still enlarge if the patient gains weight later. To maintain the contouring effect, patients need to:
- Follow a balanced diet
- Maintain a stable weight
- Exercise regularly
- Avoid lifestyle habits that lead to fat accumulation.
So, the procedure of CoolSculpting works best as an adjunct to healthy living, not a substitute for it. Patients who stay consistent with their lifestyle tend to retain results for years, whereas those who gain weight may lose the definition achieved through the procedure.
