Fat Freezing & Body Contouring in Gangnam Seoul
Eliminate stubborn fat deposits without surgery, needles, or downtime. RE:BERRY Gangnam uses Onda Coolwaves microwave technology and Berry Slim contouring injections to permanently destroy fat cells through controlled thermal targeting — achieving 20-30% fat layer reduction per session in areas resistant to diet and exercise. Physician-performed fat freezing treatments from ₩90,000, two minutes from Gangnam Station Exit 10.
What Is Fat Freezing at RE:BERRY Gangnam?
Fat freezing at RE:BERRY Gangnam uses Onda Coolwaves microwave technology and Berry Slim lipolytic injections to destroy 20-30% of subcutaneous fat cells per session in the abdomen, flanks, thighs, and submental area — starting at ₩90,000 for Berry Slim with zero surgical downtime.
At RE:BERRY Gangnam, Medical Director Dr. Yoon-Gon Ryu selects the optimal fat freezing and body contouring protocol based on each patient’s fat distribution, skin laxity, and treatment goals. The clinic’s primary fat reduction technology is Onda Coolwaves, a DEKA-manufactured device that delivers focused 2.45 GHz microwave energy to selectively heat and destroy adipocytes (fat cells) at precisely controlled depths without damaging the overlying skin. For patients seeking spot reduction of small fat deposits, Berry Slim deoxycholic acid injections offer a cost-effective alternative at ₩90,000 per 10cc session. Both approaches trigger permanent adipocyte apoptosis — meaning destroyed fat cells are eliminated through the lymphatic system over 4-12 weeks and do not regenerate. Dr. Ryu frequently combines fat freezing with Body Onda skin tightening and body contouring protocols for comprehensive results. All body treatments at RE:BERRY Gangnam are performed by licensed physicians using MFDS-certified equipment.

How Fat Freezing Works at RE:BERRY Gangnam
A physician-guided fat reduction protocol using targeted energy to permanently destroy fat cells without surgery.

Body Assessment & Fat Distribution Mapping
Dr. Yoon-Gon Ryu begins every fat freezing consultation with a full body composition assessment, measuring subcutaneous fat thickness with caliper measurements and visual analysis at each target zone: abdomen, flanks (love handles), inner/outer thighs, upper arms, bra rolls, submental (double chin), and back fat. He classifies each area by fat thickness (superficial 1-2cm vs deep 2-4cm) and skin quality to determine whether Onda Coolwaves, Berry Slim injection, or a combination fat freezing protocol will deliver optimal results. This consultation takes 15-20 minutes and is included with every treatment at RE:BERRY Gangnam.

Onda Coolwaves Microwave Fat Targeting
The Onda device delivers focused 2.45 GHz microwave energy through a specialized handpiece that selectively heats subcutaneous adipocytes to 56-60 degrees Celsius — the threshold for irreversible fat cell apoptosis — while an integrated cooling system protects the epidermis and dermis above. Unlike traditional fat freezing (cryolipolysis) that requires vacuum suction and 35-60 minute freeze cycles, Onda completes each treatment zone in 10-15 minutes with no suction marks, bruising, or post-treatment numbness. The microwave energy penetrates uniformly to a depth of 1.5-2.0cm, ensuring consistent fat freezing across the entire treated area.

Berry Slim Injection for Spot Fat Reduction
For smaller fat deposits or patients preferring injectable fat freezing alternatives, Berry Slim deoxycholic acid 10cc (₩90,000) is injected directly into subcutaneous fat pockets. Deoxycholic acid is a naturally occurring bile salt that disrupts adipocyte cell membranes, causing irreversible fat cell lysis. Each session targets a 5x5cm area. Multiple zones can be treated in a single visit. Berry Slim is particularly effective for double chin reduction, small love handles, and knee fat — areas where device-based fat freezing may not conform optimally.

Skin Tightening & Lymphatic Recovery
After fat freezing, Dr. Ryu may add Titanium lifting or InMode FX radiofrequency to tighten skin over the treated zone, preventing laxity that can occur after fat volume reduction. VacuMed lymphatic drainage therapy accelerates the elimination of destroyed fat cell debris through the lymphatic system. Patients receive written aftercare instructions in their language, including hydration guidelines (2-3 liters/day for 2 weeks), light exercise recommendations, and follow-up scheduling at RE:BERRY Gangnam.
What to Expect from Fat Freezing Treatment
- Permanent Fat Cell Destruction Fat freezing at RE:BERRY Gangnam causes irreversible adipocyte apoptosis. Destroyed fat cells are metabolized and eliminated by the body, and they do not regenerate. Adult humans cannot create new fat cells under normal conditions.
- 20-30% Fat Layer Reduction Per Session Clinical studies show Onda Coolwaves delivers 20-30% reduction in subcutaneous fat layer thickness per session at the treated zone. Most patients achieve their desired contour in 1-3 fat freezing sessions spaced 4-6 weeks apart.
- No Surgery, No Anesthesia, No Downtime Fat freezing at RE:BERRY Gangnam requires zero incisions, no general or local anesthesia, and patients return to normal activities immediately. No compression garments needed. Treatment sessions take 30-60 minutes total.
- No Suction Marks or Bruising (Onda) Unlike traditional cryolipolysis devices that use vacuum suction (leaving marks for days), Onda’s flat handpiece technology eliminates suction-related bruising, petechiae, and the uncomfortable numbness associated with older fat freezing devices.
- Simultaneous Skin Tightening Onda Coolwaves generate a secondary thermal effect in the dermis that stimulates collagen contraction and neocollagenesis, providing a skin-tightening benefit that complements the fat reduction — addressing two aging concerns simultaneously.
- Safe for All Body Areas Fat freezing with Onda treats abdomen, flanks, thighs, upper arms, back, submental area, and bra rolls. Berry Slim injections can target smaller deposits that devices cannot reach, including knee fat and armpit fat.
| Timeline | What to Expect |
|---|---|
| Day 1 | Mild warmth and erythema at the treated area lasting 1-2 hours. No pain. Return to normal activities immediately. Drink 2-3 liters of water to support lymphatic clearance of fat cell debris. |
| Week 1-2 | Treated area may feel slightly tender to deep pressure. No visible changes yet. Fat cell apoptosis process is underway at the cellular level. Light exercise encouraged to support lymphatic drainage. |
| Week 3-4 | First visible contour changes begin appearing. Fat cells are being cleared through the lymphatic system and liver. Clothes may start fitting differently around the treated zone. |
| Week 6-8 | Significant fat layer reduction measurable by caliper. Most patients see clear visual improvement by this stage. Optimal time for follow-up assessment and decision on additional fat freezing sessions. |
| Month 3 | Maximum fat freezing results achieved from first session. 20-30% fat layer reduction in the treated area. Second session can be performed if additional contouring desired. |
| Month 6-12 | Final results fully stable. Skin quality improved due to collagen tightening effect. Results are permanent as long as body weight is maintained within 5-10% of treatment weight. |

The Science Behind Fat Freezing
Peer-reviewed evidence supporting microwave-based fat reduction and injectable lipolysis.
Microwave-Based Selective Adipocyte Destruction
Onda Coolwaves technology represents a third generation of non-invasive fat freezing and fat reduction, moving beyond traditional cryolipolysis (cold-based) and HIFU (ultrasound-based) approaches. The device emits focused 2.45 GHz microwave energy that is preferentially absorbed by water molecules within adipocytes due to their high intracellular water content relative to surrounding connective tissue. This selective absorption generates localized hyperthermia (56-60 degrees Celsius) within the fat layer while the integrated Peltier cooling system maintains epidermal temperature below 42 degrees Celsius. The differential heating triggers irreversible adipocyte apoptosis through mitochondrial membrane disruption and caspase-3 activation, identical to the apoptotic pathway induced by traditional fat freezing but achieved through thermal rather than cryogenic mechanisms.
Fat Cell Apoptosis and Permanent Body Contouring
The permanence of fat freezing results relies on a fundamental principle of adipocyte biology: adult humans possess a fixed number of fat cells established during puberty, and these cells do not regenerate after destruction. When Onda Coolwaves or Berry Slim (deoxycholic acid) induce adipocyte apoptosis, macrophages phagocytose the cellular debris over 4-12 weeks. The lipid contents are processed through the liver via normal lipid metabolism pathways and do not cause systemic lipid elevation. Ultrasound measurements confirm 20-30% reduction in subcutaneous fat thickness at the treated zone at 12 weeks post-treatment, with results stable at 12-month follow-up as long as body weight remains within 10% of treatment weight.
Deoxycholic Acid Injectable Fat Reduction
Berry Slim contains deoxycholic acid (DCA), a secondary bile acid naturally produced in the human body for dietary fat emulsification. When injected into subcutaneous fat, DCA disrupts adipocyte cell membranes through a detergent-like mechanism, causing immediate cell lysis followed by inflammatory clearance and fibrotic tissue replacement. The FDA-approved version of DCA (Kybella/Belkyra) has been extensively studied in the submental region, demonstrating that 79% of patients achieved at least 1-grade improvement on the validated clinician-reported submental fat rating scale after 2-4 treatment sessions. RE:BERRY Gangnam applies this same mechanism across multiple body zones using the Korean-manufactured Berry Slim formulation.
Combination Fat Freezing and Skin Tightening Protocols
A critical consideration in non-invasive fat freezing is post-reduction skin laxity, particularly in patients over 40 or those with reduced skin elasticity. RE:BERRY Gangnam addresses this by combining Onda fat reduction with Titanium (diode laser) or InMode FX (radiofrequency) skin tightening in the same session. The secondary thermal effect of Onda Coolwaves itself generates partial collagen contraction in the deep dermis, providing an intrinsic skin-tightening benefit that traditional fat freezing (cryolipolysis) devices lack. Clinical data from DEKA’s multi-center studies demonstrate measurable improvement in skin firmness scores alongside fat reduction when using the Onda combination protocol.

What Our Patients Say About Fat Freezing
“I had been considering liposuction for my love handles for years but was afraid of surgery. The Onda fat freezing at RE:BERRY Gangnam was completely painless — I felt only warmth during the session. By week 6, my flanks were visibly slimmer and my jeans fit differently. The ₩1,090,000 Body Onda was worth every won compared to the surgical alternative.”
“I combined Berry Slim for my double chin with Onda for my abdomen during a 5-day Seoul trip. The double chin injection was ₩90,000 — incredibly affordable compared to Kybella pricing in the US. Three months later, both areas show dramatic improvement. Dr. Ryu explained the entire fat freezing process clearly in English.”
“After pregnancy, my lower abdomen had stubborn fat that would not respond to exercise. Two sessions of Onda fat freezing at RE:BERRY Gangnam reduced the area noticeably. The skin also tightened, which I did not expect from a fat reduction treatment. I recommend the combination with Titanium for the best results.”
Frequently Asked Questions About Fat Freezing
Expert answers from RE:BERRY Gangnam’s body contouring specialists.
₩90,000 for Berry Slim 10cc injection, ₩720,000 for Onda 40kJ + Titanium 40kJ combo, and ₩1,090,000 for Body Onda 100kJ at RE:BERRY Gangnam. InMode FX skin tightening add-on is ₩190,000. All prices exclude VAT (10%) and are valid April-June 2026.
1-3 sessions spaced 4-6 weeks apart are typical for noticeable fat freezing results at RE:BERRY Gangnam. Each Onda Coolwaves session reduces the treated fat layer by 20-30%. Most patients achieve satisfactory contouring after 2 sessions. Berry Slim injection may require 2-4 sessions for the same zone.
Onda offers 3 advantages over traditional CoolSculpting: (1) no vacuum suction marks or post-treatment numbness; (2) built-in skin tightening effect; (3) 10-15 minutes per zone vs 35-60 minutes. Both achieve similar 20-30% fat reduction per session. For a detailed comparison, see our Onda vs CoolSculpting guide.
1-2 on a 10-point pain scale with Onda Coolwaves at RE:BERRY Gangnam. Patients feel a warming sensation but no pain. Berry Slim injection involves brief stinging (3-4/10) during injection that subsides within minutes. No anesthesia is required for either fat freezing approach.
Yes, 95% of international patients resume normal activities including travel immediately after fat freezing at RE:BERRY Gangnam. Onda Coolwaves requires zero downtime. Berry Slim may cause mild swelling for 2-3 days in the injection area. No altitude restrictions apply to any fat freezing treatment.
7 treatment zones available at RE:BERRY Gangnam: abdomen (upper and lower), flanks/love handles, inner thighs, outer thighs, upper arms, back/bra rolls, and submental (double chin). Berry Slim can additionally target smaller areas like knee fat, armpit fat, and jowl fat at ₩90,000 per 10cc session.
Fat freezing destroys adipocytes permanently — adult humans do not regenerate fat cells. Results are permanent as long as body weight stays within 5-10% of treatment weight. Weight gain after fat freezing will distribute to untreated areas rather than the treated zone.
Fat freezing removes 20-30% of fat per session vs 70-90% with liposuction. However, fat freezing requires zero surgery, zero anesthesia, and zero downtime. Liposuction needs 2-4 weeks recovery and compression garments. RE:BERRY Gangnam specializes in non-surgical body contouring as a safer alternative.
Yes, 40% of fat freezing patients combine body contouring with facial treatments during their Seoul visit. Popular combinations include fat freezing + Ultherapy Prime (₩490,000/100 shots) or fat freezing + Thermage FLX (₩1,990,000/600 shots). Different body areas can be treated on the same day.
Berry Slim contains deoxycholic acid (10cc per vial, ₩90,000), a bile salt that dissolves fat cell membranes on contact. When injected into subcutaneous fat, it causes irreversible cell lysis within 24-48 hours. The destroyed fat is processed by the liver over 4-8 weeks. Same mechanism as Kybella (FDA-approved) at a fraction of the international price.
10-15 minutes per zone with Onda Coolwaves, or 15-20 minutes for Berry Slim injection. A comprehensive fat freezing session treating 2-3 body zones typically takes 30-60 minutes total at RE:BERRY Gangnam, including consultation and post-treatment care.
Fat freezing treatments including Onda Coolwaves and Berry Slim injection are deferred during pregnancy and breastfeeding as a medical precaution at RE:BERRY Gangnam. While these treatments are localized and non-systemic, the clinic follows conservative medical guidelines for maternal safety.
40kJ treats a partial zone (half-abdomen or one flank) while 100kJ covers a full treatment zone (entire abdomen or both flanks). The ₩720,000 Onda 40kJ + Titanium 40kJ combo adds skin tightening. The ₩1,090,000 Body Onda 100kJ provides maximum fat freezing energy for larger areas at RE:BERRY Gangnam.
Yes. Both Onda Coolwaves and Berry Slim effectively treat submental (double chin) fat at RE:BERRY Gangnam. Berry Slim (₩90,000/10cc) is particularly popular for double chin reduction due to precise injection control in this delicate area. Most patients see significant improvement after 2-3 sessions.
Before: hydrate well, avoid blood thinners 3 days prior, eat normally. After: drink 2-3 liters water daily for 2 weeks to support lymphatic drainage, engage in light exercise (walking 30+ minutes daily), avoid alcohol for 48 hours. Full aftercare instructions provided in your language at RE:BERRY Gangnam.
20-30% of the subcutaneous fat layer in the treated zone is reduced per Onda session at RE:BERRY Gangnam. In absolute terms, this translates to approximately 1-2cm reduction in fat thickness measurable by caliper at 12 weeks. For optimal results, many patients combine fat freezing with non-surgical belly fat removal protocols.
Fat freezing at RE:BERRY Gangnam is designed for patients within 5-15kg of their ideal body weight who have localized fat deposits resistant to diet and exercise. BMI below 30 is recommended for optimal results. Patients with BMI over 30 may benefit but should pursue weight management concurrently for best outcomes.
Paradoxical adipose hyperplasia (PAH) is associated with traditional cryolipolysis (CoolSculpting) at a rate of approximately 0.0051%. Onda Coolwaves uses microwave energy rather than cryogenic freezing, and no cases of PAH have been reported with Onda technology in clinical literature. Berry Slim injection also carries zero PAH risk.
40-60% lower pricing compared to US, UK, and Australia for equivalent fat freezing procedures. Korea leads globally in aesthetic device adoption, meaning RE:BERRY Gangnam uses the latest Onda generation. Additionally, Korean clinics offer body contouring combination protocols unavailable in most Western clinics.
8 languages supported at RE:BERRY Gangnam: English, Japanese, Mandarin Chinese, Thai, Vietnamese, Mongolian, Farsi, and Korean. Dedicated coordinators handle fat freezing consultation interpretation, aftercare instructions, and booking communication in your preferred language.
38% of fat freezing patients at RE:BERRY Gangnam are male. Common treatment areas for men include abdominal fat (beer belly), love handles, chest fat (gynecomastia-like deposits), and double chin. Male patients typically require higher energy settings (Onda 100kJ) due to denser subcutaneous fat distribution.
1-3cm reduction in fat thickness per session is typical at RE:BERRY Gangnam. Fat freezing is body contouring (sculpting shape) rather than weight loss. Realistic expectations: flatter abdomen, smoother love handles, defined jawline after submental treatment. Dr. Yoon-Gon Ryu provides honest assessment of achievable outcomes during consultation.
3 key differentiators: (1) DEKA Onda Coolwaves — the latest microwave technology without vacuum suction marks; (2) physician-only treatments with Dr. Ryu or Dr. Oh performing every session; (3) combination protocols with Titanium/InMode FX skin tightening to prevent post-fat-loss laxity at RE:BERRY Gangnam.
