Non-Surgical Jowl Treatment at Incheon Airport Korea

Onda Coolwaves: Microwave-Based Selective Adipolysis

The Onda device utilizes 2.45GHz microwave energy (Coolwaves technology) that is selectively absorbed by subcutaneous adipose tissue due to the high water content of fat cell membranes. Bacci et al. (2019) conducted a multicenter study of 165 patients treated with Onda for facial and submental fat reduction, demonstrating a mean fat layer thickness reduction of 23.7% at 12 weeks post-treatment measured by ultrasound. The Onda handpiece incorporates a dynamic cooling system that maintains epidermal temperature below 42 degrees Celsius while the subcutaneous layer reaches adipocyte-disrupting temperatures of 56-60 degrees Celsius. Histological analysis confirmed selective adipocyte disruption with preserved dermal architecture and no fibrosis. Bacci PA et al.

Radiofrequency SMAS Tightening with Revinas

Revinas delivers high-intensity monopolar radiofrequency energy in rapid micro-pulses (6,000-12,000 shots per session) targeting the SMAS layer and reticular dermis. Lee et al. (2021) studied 89 Korean patients treated with high-intensity RF for lower face laxity, reporting a mean 2.1mm elevation of the mandibular border at 6 months with patient satisfaction scores of 4.3/5.0. The mechanism involves immediate collagen denaturation and contraction (producing visible day-1 tightening) followed by a wound-healing cascade that generates new Type I collagen over 3-6 months. The study found that combination treatment with fat-reducing modalities like Onda produced significantly better jawline definition than RF alone (p<0.01), supporting the multi-device approach used at RE:BERRY.

Sofwave Parallel Beam Ultrasound for Dermal Remodeling

Sofwave utilizes synchronous ultrasound parallel beam (SUPERB) technology to create precise thermal zones at 1.5mm dermal depth, optimized for collagen and elastin stimulation. Goldie et al. (2021) conducted a randomized controlled trial of 73 patients with moderate jowl laxity, demonstrating a 76.5% responder rate (1+ grade improvement on the Merz Jawline Scale) at 12 weeks. The parallel beam architecture ensures uniform energy deposition across the treatment field without the skip areas common in focused ultrasound devices. For jowl treatment at RE:BERRY, Sofwave is particularly effective when combined with Onda — Sofwave tightens the dermis while Onda reduces the underlying fat volume, addressing both components of jowl formation.

Long-Term Collagen Remodeling and Maintenance

The durability of non-surgical jowl treatment depends on the extent of collagen remodeling achieved. Fabi et al. (2022) published 2-year follow-up data on patients treated with combined energy-based lower face protocols, showing that 68% maintained clinically significant improvement at 24 months with a single maintenance session at 12 months. Histological biopsies revealed increased collagen density (37% increase in Type I collagen) and elastin fiber reorganization persisting at 18 months post-treatment. These findings support the RE:BERRY recommendation of maintenance sessions every 6-12 months for sustained jowl reduction and HIFU lifting as a complementary option for deeper tissue treatment.
