Thermage FLX vs Onda Lifting Comparison Guide 2026
A physician-authored, evidence-based comparison of two leading non-surgical lifting technologies available at RE:BERRY Incheon Airport. Thermage FLX uses monopolar radiofrequency for volumetric dermal heating, while Onda uses 2.45GHz Coolwaves microwave technology for targeted fat reduction and skin tightening.
Thermage FLX vs Onda: Which Should You Choose?
Thermage FLX is better for overall skin tightening and collagen renewal across the full face, especially for patients with skin laxity but minimal fat concerns. Onda is better for combined fat reduction and skin tightening, particularly for the lower face, jowls, double chin, and body areas. At RE:BERRY Incheon Airport, many patients achieve optimal results by combining both technologies in a single session.
Thermage FLX by Solta Medical (Bausch Health) uses monopolar radiofrequency at 6.78 MHz to deliver volumetric heating across the dermis and subcutaneous tissue. Its AccuREP technology automatically optimizes energy delivery per pulse based on tissue impedance feedback. The latest FLX platform features a Total Tip 4.0 with 40% more treatment area per pulse and a vibrating handpiece for improved comfort. Thermage has over 20 years of clinical data and more than 1.5 million treatments performed globally. Onda by DEKA uses 2.45 GHz microwave Coolwaves technology with three specialized handpieces: Coolwaves for subcutaneous fat disruption, Coolwaves Shallow for superficial skin tightening, and Coolwaves Deep for deep tissue remodeling. The microwave frequency selectively targets water molecules in adipocytes while the integrated cooling system protects the epidermis. Onda has MFDS and CE certification with growing clinical evidence. RE:BERRY Incheon Airport stocks both devices at full specification with manufacturer certifications from Solta Medical and DEKA, allowing your physician to recommend the optimal approach or combination protocol based on your specific anatomy and goals.

How We Determine Thermage vs Onda for Your Goals
Our physician-led consultation process ensures you receive the optimal technology for your specific needs.
Comprehensive Assessment
Dr. Cho evaluates skin laxity, subcutaneous fat thickness, tissue quality, and your aesthetic goals. We assess whether your primary concern is skin tightening (favoring Thermage) or combined fat reduction + tightening (favoring Onda).
Technology Selection & Protocol Design
Based on assessment, your doctor recommends Thermage FLX, Onda, or a combination protocol. Parameters are calibrated for your skin type, treatment area, and desired outcome intensity.
Energy Delivery
Thermage FLX: 30-45 minutes, 300-600 shots with Total Tip 4.0 and comfort vibration. Onda: 20-30 minutes, 100kJ protocol with Coolwaves handpiece and integrated cooling. Combined: sequential treatment in one session.
Aftercare & Follow-Up
Minimal downtime for both technologies. Soothing care applied. Before-and-after comparison photos scheduled at 4, 8, and 12 weeks. Results develop progressively as collagen remodeling occurs.
Thermage FLX vs Onda: When to Choose Each
- Choose Thermage FLX When: Primary concern is skin laxity/tightening without significant fat reduction. Best for full face, periorbital, and forehead tightening.
- Choose Onda When: Primary concern includes fat reduction alongside tightening. Best for jowls, double chin, body contouring, and areas with subcutaneous fat.

The Science: Radiofrequency vs Microwave Lifting
Understanding the fundamental differences in how Thermage FLX and Onda achieve their clinical effects.
Thermage FLX: Monopolar Radiofrequency Mechanism
Thermage FLX delivers 6.78 MHz monopolar radiofrequency energy through a capacitively coupled electrode. The electromagnetic field generates resistive heating throughout the dermis and superficial subcutaneous tissue, raising temperatures to 65-75 degrees Celsius within collagen-rich zones. This thermal stimulus causes immediate collagen fiber contraction (the initial tightening effect) followed by a wound-healing cascade that stimulates fibroblast activity and new collagen synthesis over 2-6 months. The AccuREP (Accutune Repeat) technology measures tissue impedance 50 times per second and automatically adjusts energy delivery to maintain optimal heating regardless of tissue heterogeneity.
Onda Coolwaves: Microwave Technology Mechanism
Onda delivers 2.45 GHz microwave energy (Coolwaves) that selectively targets water molecules within adipocytes. At this frequency, electromagnetic energy is preferentially absorbed by water-rich fat tissue while the integrated cooling system maintains epidermal temperatures below the damage threshold. The thermal energy induces adipocyte apoptosis (programmed cell death) through membrane disruption, and the released lipids are gradually metabolized through the lymphatic system over 4-12 weeks. Simultaneously, dermal heating stimulates fibroblast activity and neocollagenesis for a secondary skin tightening effect.
Comparative Clinical Evidence
Fritz et al. (2019) demonstrated that Thermage FLX Total Tip 4.0 produces statistically significant improvement in skin laxity scores with a 94% patient satisfaction rate at 6 months. Key (2014) showed histological evidence of new collagen formation at 2 and 6 months post-treatment with radiofrequency devices. For Onda, Tuccillo et al. (2020) demonstrated a 20-25% reduction in subcutaneous fat thickness measured by ultrasound at 90 days, with simultaneous skin tightening improvement. Bacci et al. (2019) reported 86% patient satisfaction with Onda for body contouring with minimal adverse events. No head-to-head Thermage vs Onda randomized controlled trial exists as of 2026, underscoring the importance of physician expertise in device selection.

What Patients Say About Thermage and Onda
“Dr. Cho recommended Onda for my jowls and double chin area rather than Thermage because my primary concern was fat, not just skin laxity. The results at 3 months proved he was right.”
“I have had Thermage at another clinic before and came to RE:BERRY for a combined Thermage + Onda protocol. The combination gave me significantly better results than Thermage alone.”
“The honest consultation impressed me. Dr. Cho told me Onda would be sufficient for my goals instead of upselling me on the more expensive Thermage option.”
Frequently Asked Questions: Thermage FLX vs Onda Lifting
Expert answers to help you choose the right lifting technology for your goals.
Neither is universally better. Thermage FLX excels at overall skin tightening for laxity without significant fat concerns. Onda excels at combined fat reduction and skin tightening. Your physician at RE:BERRY will recommend based on your individual anatomy and goals.
Thermage FLX pricing is available during consultation. Onda 100kJ is ₩650,000 (regular ₩1,290,000). The Double Line-Up Lifting package (Sofwave 100 + Onda 100kJ) is ₩1,590,000. All prices exclude VAT.
Yes. Many patients at RE:BERRY Incheon Airport receive Thermage for overall face tightening followed by Onda for targeted fat reduction in jowls and submental area in a single visit. This combination protocol produces comprehensive results.
Both have essentially zero downtime. Mild redness resolves within 1-2 hours for both technologies. Both are safe for same-day air travel, making them ideal for international patients at our Incheon Airport location.
Onda fat reduction is permanent because destroyed fat cells do not regenerate. However, skin tightening from both Thermage and Onda collagen remodeling lasts approximately 12 months, requiring annual maintenance sessions.
Both are well-tolerated. Thermage FLX rates 3-5/10 with its comfort vibration feature. Onda rates 2-4/10 with integrated cooling. Most patients describe both as a warm sensation.
Yes. Thermage FLX is FDA-cleared (510(k)) for non-invasive treatment of wrinkles and rhytides. It is also MFDS-approved in Korea. Onda has CE marking and MFDS approval.
Thermage FLX: full face, forehead, periorbital, jawline, neck, body (with body tip). Onda: face, jowls, submental area, abdomen, flanks, thighs, arms, and other body areas. Onda is particularly versatile for body contouring.
Thermage FLX: typically 1 session with annual maintenance. Onda: 1-3 sessions spaced 4-6 weeks apart depending on the treatment area and fat volume. Combined protocols: usually 1 comprehensive session.
Onda is generally preferred for double chin because it targets both the submental fat and skin laxity. Thermage addresses skin laxity but does not directly reduce fat volume. For pure skin tightening under the chin, Thermage is also effective.
Thermage FLX with its specialized eye tip is the gold standard for periorbital skin tightening. Onda is not typically used for the delicate eye area. For eye concerns, we recommend the Eye Repair Package (Eye Oligio 200 shots + Eye Rejuran 2cc, ₩840,000).
No. Thermage uses radiofrequency (6.78 MHz electromagnetic energy) which generates resistive heating in tissue. Onda uses microwave (2.45 GHz) which targets water molecule oscillation. Different physical mechanisms produce different tissue effects.
Neither fully replaces a surgical facelift for severe skin laxity. Both produce subtle, natural-looking improvement best suited for mild to moderate laxity. For severe laxity, combination protocols at RE:BERRY can maximize non-surgical results before considering surgery.
All treatments are performed by Head Director Dr. Cho Sung-Jun (License #138858) or Dr. Kim Dong-Young (License #147291). Both physicians are certified by Solta Medical (Thermage) and DEKA (Onda).
Yes. RE:BERRY holds manufacturer certification from Solta Medical for Thermage FLX and DEKA for Onda Coolwaves. Both devices are genuine, MFDS-certified units — we never use counterfeit or grey-market equipment.
Yes. Thermage FLX takes 30-45 minutes. Onda takes 20-30 minutes. Combined with airport pickup and consultation, plan for 2-3 hours. Both require zero downtime for flying.
While both can treat body areas, Onda is more effective for localized fat reduction in abdomen, flanks, inner thighs, and upper arms. Onda’s microwave technology selectively targets adipocytes, which Thermage’s radiofrequency does not do as effectively.
Both show significant improvement at 6 months. Thermage produces uniform tightening. Onda produces combined fat reduction and tightening. Combined protocols show the most comprehensive improvement. Your doctor will show you comparable before-and-after cases during consultation.
AccuREP (Accutune Repeat) measures tissue impedance 50 times per second and automatically adjusts energy delivery for consistent heating regardless of tissue differences. This ensures uniform results across all treated areas.
Coolwaves is DEKA’s proprietary 2.45 GHz microwave technology. At this specific frequency, electromagnetic energy is preferentially absorbed by water-rich adipocytes (fat cells), causing selective thermal disruption while integrated cooling protects the skin surface.
Yes. Complimentary airport pickup from Incheon International Airport Terminal 1 or Terminal 2 is available for all treatment bookings. Contact our multilingual coordination team to arrange.
We set realistic expectations during consultation by showing comparable before-and-after cases. If results are not meeting expectations at follow-up, your doctor will assess whether additional treatment sessions or protocol adjustments would be beneficial.
RE:BERRY accepts cash, all major credit cards (Visa, Mastercard, JCB, UnionPay), Alipay, WeChat Pay, and wire transfer.
Both are contraindicated for patients with pacemakers, metal implants in the treatment area, or active skin infections. Pregnancy is also a contraindication. Your doctor will review your full medical history during consultation.
