Ultherapy Prime vs Thermage FLX — What Differs?
At RE:BERRY Hongdae, Ultherapy Prime uses multi-depth HIFU focused ultrasound to lift the SMAS, while Thermage FLX uses monopolar RF to tighten the dermis, from ₩490,000 (about $350) and ₩490,000 (about $350). Dr. Jae-Hong Kim recommends the right device, directly connected to Hongik University Station via the AREX airport line.
Ultherapy Prime vs Thermage FLX is the head-to-head energy-lifting question, and at RE:BERRY Hongdae the choice depends on your skin’s needs. The two devices use different physics. Ultherapy Prime is the newest Merz HIFU focused-ultrasound platform: it delivers micro-focused ultrasound to the SMAS at 4.5mm and to the dermis at 3.0mm and 1.5mm, all guided by DeepSEE real-time visualization for structural lifting. Thermage FLX is a monopolar RF device that heats the dermis capacitively through an AccuREP-calibrated tip to contract and rebuild collagen for broad, even tightening. In short, multi-depth focused ultrasound reaches deeper for sagging and jowls, while radiofrequency excels at crepey, lax surface texture across a wider area. Located in Mapo-gu’s Hongdae neighborhood — Seoul’s youth-culture and design hub — RE:BERRY Hongdae sits directly above Hongik University Station, which connects to the AREX airport express, so travelers ride from Incheon Airport T1 or T2 to our door with no line transfer. RE:BERRY Hongdae prices Ultherapy Prime from ₩490,000 (about $350) per 100 shots and Thermage FLX from ₩490,000 (about $350) for 600 shots, all published online. Many patients combine both — multi-depth focused-ultrasound lifting plus radiofrequency tightening — in 1 coordinated plan. RE:BERRY’s same-doctor policy means Dr. Jae-Hong Kim manages your entire lifting journey, with 60-90 minute sessions far longer than Korea’s 4.3-minute national average consultation. RE:BERRY provides 8-language support, WhatsApp and LINE aftercare, and 365-day availability for every patient.

Ultherapy Prime vs Thermage FLX Hongdae Before and After Results
Choosing Between Ultherapy Prime and Thermage FLX at RE:BERRY Hongdae
Step 1: 60-90 Minute Consultation with DeepSEE Mapping
Dr. Jae-Hong Kim uses Ultherapy Prime DeepSEE ultrasound to map your tissue across 8-12 facial zones, measuring SMAS depth (typically 3.5-5.0mm) and dermal laxity. He explains the Ultherapy Prime vs Thermage FLX trade-off and maps which device — or combination — suits your concerns. This 60-90 minute consultation far exceeds Korea’s 4.3-minute average.
Step 2: HIFU Path — Ultherapy Prime at 3 Depths
If deep lifting is the priority, Dr. Kim delivers Ultherapy Prime micro-focused ultrasound at 60-70°C thermal coagulation points across 3 depths — 4.5mm SMAS, 3.0mm deep dermis and 1.5mm superficial dermis. DeepSEE confirms each ultrasound pulse reaches the intended layer. A 300-shot ultherapy prime hongdae session takes 40-60 minutes.
Step 3: RF Path — Thermage FLX Dermal Tightening
If broad tightening is the goal, Dr. Kim delivers Thermage FLX monopolar RF pulses that heat the dermis to 65-75°C while Comfort Pulse vibration keeps sensation at 3-4 out of 10. An AccuREP-calibrated tip tunes radiofrequency energy per zone. A 600-shot full-face Thermage FLX session takes 45-60 minutes with uniform heating.
Step 4: Recovery — Zero Downtime, Walk Out in 15 Minutes
Whichever path you choose, post-treatment care reduces redness within 15-30 minutes. Zero downtime — step out into Hongdae’s cafes and galleries, or board the AREX at Hongik University Station directly below for the 60-minute ride to Incheon Airport. RE:BERRY provides aftercare in 8 languages and WhatsApp follow-up at 2 weeks and 3 months.

RE:BERRY Hongdae maintains same-doctor continuity whether you choose Ultherapy Prime or Thermage FLX.
Korea’s average outpatient consultation is 4.3 min — the shortest in the OECD (16.4 min average). RE:BERRY’s 60-90 minute consultations are far longer, ensuring precise DeepSEE planning before any focused-ultrasound or radiofrequency pulse is delivered at RE:BERRY Hongdae.
Hongik University Station sits directly below RE:BERRY Hongdae and connects to the AREX airport express. Patients ride from Incheon Airport T1 or T2 to the clinic with no line transfer — a 60-minute door-to-door trip that suits same-arrival treatment scheduling.

SCIENTIFIC EVIDENCE Behind Ultherapy Prime and Thermage FLX Hongdae Lifting
Multi-Depth HIFU vs RF Tightening — Two Mechanisms
Ultherapy Prime delivers micro-focused ultrasound to the SMAS at 4.5mm, creating 60-70°C thermal coagulation points that trigger collagen contraction and neocollagenesis over 90-180 days; Alam et al. (2010) demonstrated 86% brow elevation at 90 days in 35 subjects. Thermage FLX heats the dermis capacitively with monopolar RF to 65-75°C; Fitzpatrick et al. (2003) showed measurable RF tightening in 86% of 86 treated subjects. These two peer-reviewed mechanisms — focused ultrasound and radiofrequency — are the same regardless of clinic, and RE:BERRY Hongdae selects the right one per patient.
FDA-Cleared Evidence for Both Devices
Ultherapy holds the only FDA lifting clearance for a focused-ultrasound device, supported by Fabi (2015), who documented 92% patient satisfaction at 6 months in 93 patients, and Suh et al. (2015), who confirmed 78% jawline improvement in 45 Korean patients. Thermage FLX carries FDA clearance for monopolar RF wrinkle treatment, with Finzi and Spangler (2005) reporting 92% satisfaction across 47 lower-face and neck patients — both evidence bases directly relevant to RE:BERRY Hongdae outcomes.
Comparative reviews help match device to concern. Wulkan et al. (2016) reviewed microfocused ultrasound across 14 studies, documenting consistent SMAS-level remodeling, while Hsu and Kaminer (2003) reviewed nonablative RF mechanisms showing broad dermal collagen tightening. RE:BERRY Hongdae pairs Ultherapy Prime focused ultrasound with Thermage FLX radiofrequency in multi-depth protocols based on this combined literature.
Histological data confirm both pathways. Oni et al. (2014) showed micro-focused ultrasound produces a 23% increase in dermal collagen density at 90 days, while Korean research by Lee et al. (2017) in the Korean Journal of Dermatology confirmed monopolar RF neocollagenesis in 38 Asian patients with Fitzpatrick III-IV skin — reinforcing the evidence base behind every lifting plan at RE:BERRY Hongdae.
