Sofwave vs Onda for Jawline Contouring in Myeongdong Seoul — SUPERB vs Coolwaves Technology

Sofwave SUPERB: Synchronous Parallel Beam Collagen Remodeling

Sofwave’s Synchronous Ultrasound Parallel Beam (SUPERB) technology represents a distinct approach to collagen remodeling compared to traditional HIFU devices. Instead of delivering single-point micro-focused energy like Ultherapy, Sofwave generates 7 parallel ultrasound beams simultaneously from a cylindrical transducer, creating a continuous volumetric thermal zone at precisely 1.5mm depth in the mid-dermis. This band of controlled thermal injury (reaching 60-70 degrees Celsius) denatures existing collagen fibrils while preserving the epidermis through integrated Sofcool contact cooling. The wound-healing cascade subsequently replaces denatured collagen with new, tightly organized Type I collagen fibers. Goldie et al. (2021) published a prospective study of 116 subjects treated with SUPERB ultrasound technology showing 74% of subjects demonstrated improvement in jawline laxity at 12-week follow-up, with continued improvement at 24 weeks. The treatment requires no anesthesia and produces no downtime — making it particularly suitable for the jawline area where post-procedure swelling would be cosmetically conspicuous.

Onda Coolwaves: Selective Microwave Adipocyte Apoptosis

Onda’s Coolwaves technology utilizes 2.45GHz microwave energy — a frequency specifically absorbed by water molecules within adipocytes. Unlike radiofrequency energy which heats all tissue non-selectively, Coolwaves microwave energy is preferentially absorbed by the high water content of fat cells (approximately 15% water) and fibrous septae while passing through the lower-water-content dermis with minimal thermal effect. The targeted heating raises adipocyte internal temperature to 56 degrees Celsius, triggering controlled apoptosis rather than necrosis — resulting in gradual, natural-looking fat reduction without inflammation, bruising, or skin irregularity. Bacci et al. (2019) demonstrated in a controlled clinical trial that Onda Coolwaves technology produced a mean 2.1cm reduction in abdominal circumference after a single session, with fat reduction confirmed by ultrasound measurement at 90 days. For jawline contouring, the Deep handpiece targets jowl fat pads and submental adipose tissue to reduce volume along the mandibular border and create sharper jawline definition. The Shallow handpiece simultaneously tightens the overlying dermis, producing a dual contouring effect.

Multi-Energy Combination for Jawline Contouring

Contemporary jawline contouring increasingly employs multi-energy strategies targeting different tissue depths and compositions. Sofwave addresses collagen laxity at 1.5mm while Onda targets adipose tissue at 5-15mm — a complementary pairing that addresses the two primary causes of jawline blurring: skin looseness and fat accumulation. Oni et al. (2021) reviewed multi-modality non-invasive body contouring protocols and found that combining distinct energy sources targeting different tissue layers produced 25-40% greater circumference reduction than single-device protocols. At RE:BERRY Myeongdong, Dr. Seung-Jae Baek applies this principle to facial contouring by pairing Sofwave with Onda Coolwaves and frequently adding Revinas micro-focused RF for nasolabial fold and double chin definition, creating a three-layer jawline optimization protocol.
