Ulthera Thermage Combo in Seoul — Maximum Lifting Without Surgery

Why Combining HIFU and RF Outperforms Monotherapy

The scientific rationale behind the Ulthera Thermage combo lies in the principle of multi-depth tissue targeting. Micro-focused ultrasound (MFU-V), the technology behind Ultherapy, delivers focused energy at precisely defined depths of 3.0mm, 4.5mm, and 1.5mm, creating discrete thermal coagulation points (TCPs) that reach temperatures of 60-70°C. These TCPs trigger immediate collagen denaturation and contraction, followed by a wound-healing cascade that produces new, organized collagen over 2-6 months. Radiofrequency devices, by contrast, deliver volumetric heating to the dermis at 42-45°C, stimulating fibroblast activity and extracellular matrix remodeling across a broader area. When combined in a single session — the Ulthera Thermage combo approach — the two mechanisms create complementary effects: HIFU provides focal, structural lifting at the SMAS, while RF delivers diffuse dermal tightening.

Clinical Evidence for MFU-V Efficacy

Alam et al. (2010) published a pivotal randomized controlled trial demonstrating that a single MFU-V treatment produced clinically significant brow lifting at 60 days, with 86% of subjects showing improvement on the Global Aesthetic Improvement Scale. Histological analysis confirmed new collagen formation at the treatment depth. A subsequent long-term study by Fabi et al. (2015) showed that MFU-V results persisted for up to 24 months, with continued dermal and subdermal collagen remodeling documented by ultrasound imaging. These findings establish Ultherapy as the only non-invasive device FDA-cleared specifically for lifting the eyebrow, neck, and submental region.

Radiofrequency Combination Synergy

The synergistic benefit of combining HIFU with RF was investigated by Pak et al. (2020), who compared outcomes in patients receiving MFU-V alone versus MFU-V combined with monopolar radiofrequency. The combination group showed statistically superior improvement in skin laxity scores at 3 months (p<0.05), with patient satisfaction rates of 89% compared to 71% for monotherapy. The authors attributed this to complementary collagen remodeling across multiple tissue planes. At RE:BERRY Myeongdong, the Ulthera Thermage combo protocol builds on this evidence by incorporating next-generation RF devices such as Sofwave (SUPERB technology) and Onda (2.45 GHz Coolwaves), which offer more precise energy delivery than the monopolar RF used in the study.

Collagen Remodeling at the Molecular Level

At the molecular level, thermal injury from both HIFU and RF triggers the heat shock protein (HSP) 47 pathway, which acts as a molecular chaperone for procollagen synthesis. Suh et al. (2018) demonstrated through in vivo biopsies that HSP47 expression increased 3.2-fold at 4 weeks post-treatment with combined energy devices, compared to 1.8-fold with single-device treatment. This elevated HSP47 activity directly correlates with increased type I and type III collagen deposition, explaining the superior clinical outcomes observed with the Ulthera Thermage combo versus monotherapy approaches.
