A targeted approach for stubborn fat and a shapelier silhouette
Cooltech Define is the latest-generation non-invasive fat reduction treatment in Singapore, designed to permanently reduce fat by up to 30%.
Named HerWorld Best Body-Shaping Treatment 2026, Cooltech Define is Singapore’s leading choice for non-invasive fat reduction.
Powered by 360° cooling technology, 9 configurable applicators, and a patented Cool Gel Pad system, it delivers targeted fat reduction across the abdomen, flanks, thighs, arms, and more — with zero downtime and results that speak for themselves.
Cryolipolysis (fat freezing) has been among Singapore’s most popular non-invasive fat reduction treatments for over a decade — but older technologies often delivered inconsistent results and raised concerns around safety and comfort, eroding confidence in the category.
Cooltech Define sets a new standard. Backed by PubMed-published clinical studies and an established safety profile, it delivers what earlier fat freezing treatments couldn’t — reliable, measurable fat reduction results.
Cooltech Define fat reduction treatment is built around a safety-first architecture — clinically validated, precisely engineered, and designed for consistent fat reduction with minimal risk.
At OZ Aesthetic, every treatment is delivered exclusively by Cooltech-certified specialists using structured safety templates, making it one of Singapore’s most trusted choices for non-invasive fat reduction.
Even, Predictable, Low-Risk Fat Freezing
Unlike older cryolipolysis machines with flat cooling plates, Cooltech Define uses true circumferential 360° cooling, which provides:
More uniform fat crystallisation
Lower risk of Paradoxical Adipose Hyperplasia (PAH)
Safer, more controlled temperatures at –10°C for 70 minutes
This uniform cooling is the key to safer and more consistent fat reduction.
Over 1,000,000 treatments performed worldwide
Installed in 40+ countries
Multiple clinical publications confirming efficacy and safety
Proven 21mm average fat reduction and high patient comfort levels
Cooltech Define is supported by extensive clinical studies and global treatment numbers, making it one of the most clinically valid cryolipolysis devices in the market today.
for Maximum Skin Protection
Cooltech Define features the world’s first patented RFID cryoprotective gel pad, engineered to:
Prevent skin injury
Enhance thermal protection
Ensure correct single-use application
Improve conductivity for safer, faster cooling
This is a critical safety feature that older fat freezing brands do not offer.
for Safe & Accurate Mapping
Cooltech Define comes with 9 anatomical templates that allow our specialists to map out precise treatment areas for:
✓ Abdomen ✓ Flanks ✓ Arms ✓ Inner/outer thighs
✓ Back fat ✓ Banana roll
These templates ensure:
Accurate fat pocket isolation
Symmetrical placement
Lower risk of nerve or muscle overlap
Consistency across multiple sessions
This systematic approach is how OZ Aesthetic ensures safe, repeatable results every time.
Cooltech Define fat reduction treatment is designed to treat localised, pinchable fat that does not respond to diet or exercise. Using 360° cooling technology across 9 uniquely shaped applicators, it adapts safely to multiple body contours — making it suitable for both men and women looking to achieve more refined, sculpted silhouette lines.
Cooltech Define targets subcutaneous fat, not visceral fat, making it ideal for precision fat reduction of specific problem areas. Whether your goal is belly fat reduction, slimmer flanks, or more defined thighs, Cooltech Define’s fat freezing technology delivers targeted cryolipolysis where it matters most.
Stubborn fatty bulges that resist diet & workouts
Localised fat pockets around abdomen or thighs
Asymmetrical fat distribution (one side bigger than the other)
Post-pregnancy lower tummy fat
Hormonal fat in the hips / thigh area
Back rolls, bra-line bulges
Sculpting for a more defined waistline or bodyline
Body contouring without downtime or surgery
At OZ Aesthetic, Cooltech Define isn’t just a fat reduction treatment — it’s a complete body contouring and sculpting experience.
True 360° cooling technology, applicators shaped for Asian body contours, Korean-inspired bodyline design, and certified specialists backed by structured assessment protocols. Every element is chosen to deliver fat reduction outcomes that are safe, consistent, and refined to your goals.
360° Cooling for More Uniform Fat Reduction
Cooltech Define is the latest flagship model from Cocoon Medical (part of the Sinclair group). It features true 360° cooling applicators that surround the treated fat pocket completely — unlike older flat cooling plates.
This creates:
More even fat freezing across the entire bulge
Stronger and deeper cooling, reaching up to –10°C for 70 minutes
More predictable, consistent slimming results
Lower risk of PAH due to uniform cooling
Less discomfort thanks to optimised suction levels
Its safety and effectiveness are validated by large-scale clinical studies showing:
98% patient satisfaction
Low complication rates
No significant changes in blood lipid levels post-treatment
Cooltech Define offers 9 ergonomic applicators to precisely target different fat pockets.
This ensures:
Better contouring for abdomen, flanks, arms, thighs, back, banana roll, bra fat, and underarms
Tighter fit = faster cooling = better fat apoptosis
Treatment of multiple areas simultaneously (up to 4 at once)
Precision, Symmetry, and Natural Contours
OZ Aesthetic follows a Korean-inspired contouring philosophy that goes beyond simply “shrinking fat”. We shape the silhouette, not just the treatment area.
This approach is guided by:
Understanding Asian fat distribution and body shapes
Maintaining feminine or masculine curvature and shaping ideal figure lines
Avoiding “over-freezing” or “flat spots”
Ensuring both sides remain symmetrical and natural
Our therapists are trained to combine Cooltech Define precision with the Korean aesthetic sense of proportion — giving you a refined and natural result that enhances your overall silhouette.
Your treatments are performed by a dedicated team of Cooltech Define–certified therapists, including lifestyle and body-mapping specialists trained under the Ozhean Group’s Korean protocols.
Our specialists provide:
Understanding Asian fat distribution and body shapes
Optimal applicator selection
Safe & comfortable treatment setup
Realistic result forecasting
Aftercare and lymphatic stimulation recommendations
They are trained not just to “apply a machine,” but to engineer a result.
Before every Cooltech Define treatment, we conduct a structured assessment to ensure both safety and effectiveness:
InBody Composition Scan – to evaluate fat %, visceral fat trends & suitability
Cooltech Define Eligibility Checklist – to rule out contraindications
Pinch-Fat Measurement – to confirm correct applicator fit
Optional Medical Screening – for clients with health concerns
Lifestyle Assessment – for personalised body goals
This ensures you receive a safe, medically responsible, and scientifically appropriate fat-freezing plan.
Cooltech Define kills fat cells — but your body needs to remove them naturally.
At OZ Aesthetic, we integrate optional enhancements that accelerate results:
Manual lymphatic drainage after your session
Pneumatron body detox (optional) for faster clearance
Lifestyle coaching to optimise fat metabolism
Optional Cryowave or EMS muscle toning add-ons
Consistent follow-up and progress tracking
This holistic approach enhances results beyond standalone cryolipolysis.
Cooltech Define is the flagship device under Cocoon Medical and Sinclair — internationally recognised for medical-grade equipment.
Clinical studies show:
21mm average fat reduction (ultrasound measured)
Very minimal downtime
High comfort levels (VAS 2.66/10)
No major adverse events reported
This makes Cooltech Define one of the safest and most validated fat freezing systems in Singapore today.
At OZ Aesthetic, every session of Cooltech Define fat reduction treatment follows a structured Korean-inspired protocol so your treatment is safe, comfortable and predictable from start to finish.
Before proceeding, we perform a Cooltech Define safety screening to ensure the treatment is suitable for you. This includes:
A medical and lifestyle questionnaire
Screening for contraindications (e.g. cold-related conditions, hernia, pregnancy)
Clarifying current medications or medical history
Only clients who clear this step will proceed to treatment planning.
Next, we conduct a body composition analysis and local fat assessment:
InBody scan to understand fat %, distribution and trends
Pinch-fat measurement of targeted areas to ensure there is enough subcutaneous fat for cryolipolysis
Discussion of ideal areas for Cooltech Define vs where lifestyle or other treatments may be better
This allows us to plan safely and set realistic expectations.
Using Cooltech Define’s anatomical templates and 9 ergonomic applicators, our specialist will:
Mark out precise treatment zones (abdomen, flanks, thighs, arms, bra fat, etc.)
Choose the best applicator size and shape for each fat pocket
Plan how many areas to treat in one session (up to 4 areas at once)
This step ensures accurate placement, symmetry and optimal cooling contact.
Before the applicators are applied, we prepare the skin and area:
Take standardised before photos for future comparison
Cleanse and dry the treatment area
Apply the patented RFID Cool Gel Pad to protect your skin and enhance safe cold conduction
Position you comfortably on the treatment bed
When the Cooltech Define applicator starts:
You will first feel gentle suction pulling the fat into the cup
This is followed by an intense cold sensation that settles into numbness within a few minutes
The treatment typically runs around 70 minutes at up to –10°C, depending on the area and protocol
During this time, you can relax, use your phone, or rest. Most clients describe the experience as tolerable with mild discomfort only.
Once the cycle is complete:
The applicator and gel pad are gently removed
The area will look temporarily firm or slightly raised (“frozen butter” appearance)
This step supports better fat clearance and overall results.
Immediately after treatment, you can return to normal activities. You may notice:
Mild redness, swelling, tingling or numbness for a few hours to days
Occasional sensitivity or bruising in treated areas
We will give you simple aftercare advice (hydration, gentle activity, what to avoid) and explain when to expect visible changes — usually from 4 weeks, with continued improvement up to 12 weeks as your body clears the treated fat cells.
A follow-up review is usually scheduled to:
Compare before–after photos
Review inch / contour changes
Decide if additional Cooltech Define cycles are needed for certain areas
Discuss how Cooltech Define can be integrated with other Oz treatments (e.g. skin tightening or muscle toning)
This completes your Cooltech Define body contouring journey — with results that are gradual, natural and permanent in the treated fat cells.
Your journey starts with a 1-to-1 consultation with our Cooltech Define specialist. We will:
Understand your concerns (tummy, thighs, arms, bra fat, etc.)
Clarify your body goals and ideal silhouette
Explain how Cooltech Define 360° cryolipolysis works and what kind of results are realistic
This is also where you can ask any questions about safety, downtime and expected outcome.

I always believe that there is no shortcut to having a slim figure, that is clean and exercise regularly. However, it is also impossible to spot slim certain part of the body. Thus, I decided to try out fat freeze treatment with ozhean zoey since tummy and love handles fat bulges have always been a concern for me…
I had come to OZ intending to undergo their trial for fat freeze treatment. Novin, who was very kind and ethical, explained patiently to me that the treatment wouldn’t be suitable for me as I do not have much fats, as the ‘fats’ were all primarily loose skin. Impressed by her professionalism, I decided to try their facials and subsequently signed up with them…
Eileen Gan and Kelly are both incredibly professional and attentive. Their beauty services are top-notch — they take the time to understand your needs and deliver results that truly exceed expectations. The whole experience feels comfortable, relaxing, and very well taken care of. Highly recommend them if you’re looking for quality and expertise!
Fat freeze reduces my stubborn fat visibly, which complements my workout and proper eating. More effective if you don’t have loose skin to start off with – which you can try Legacy for tightening. #selfcare
The service is excellent! I love their Hydrafacial and fat freeze treatments! I was a sceptic for the fat freeze treatment but it works! Look for Novin, she is amazing!
Initially I was quite afraid to try this out but the therapists are very friendly and explained the procedure in detail. Without changing my lifestyle, I still managed to see very visible improvements to my body shape. I also liked how the therapist would advise the number of treatments that minimally would be required and there’s no hard selling. The treatments are also painless…
Agnes was enthusiastic, professional in her explanations, and skilled in her techniques. It was a very comfortable experience, and I will definitely go back to her.
The treatment is effective, could see the obvious improvement. The therapist Agnes is very professional and attentive. Her treatment is good and nice.
I had my first experience with Cooltech, not knowing fully what to expect. When I arrive and was promptly welcomed by manager Eileen Gan and therapist Kelly, they immediately put me at ease. Eileen patiently introduced the benefit of the latest technology of fat freeze Cooltech and shared many success stories with me. Kelly started to carefully measure my body fat using various methods to document my stats…

Most clients begin noticing changes as early as 3–4 weeks, with the most visible results appearing between 8–12 weeks as the body naturally clears the crystallised fat cells. Clinical studies show continued improvement up to 90 days after treatment.
Cooltech Define permanently removes the treated fat cells through apoptosis. Once cleared, these fat cells do not return. However, remaining fat cells can still enlarge with weight gain. Maintaining a stable lifestyle helps preserve your results long-term.
A typical session lasts about 50–70 minutes per cycle, depending on the area. Cooltech Define allows up to 4 areas to be treated simultaneously, which significantly reduces total treatment time.
Most areas require 1–2 sessions, spaced 6–8 weeks apart. This allows your body sufficient time to clear the treated fat cells before reassessing if additional sculpting is needed. Your therapist will advise based on your goals and fat distribution.
Discomfort is generally very mild. You may feel strong suction and intense cold for the first few minutes, which quickly settles into numbness. Clinical studies report a low pain score (VAS ~2.66/10), making it one of the more comfortable fat-freezing options available.
