Hello! This is Seye Clinic, embracing all the beauty in the world.
For patients seeking the ultimate non-surgical facelift in Seoul, combining Ultherapy Prime and Thermage FLX—known as "Ulthermage"—delivers superior results. This dual-modality treatment targets both deep muscle fascia (SMAS) and the dermal layer, providing up to 18 months of comprehensive lifting and tightening with zero downtime.
In our practice, we consistently see patients who feel their face is "melting" or losing its sharp contours, especially after age 35. According to a 2023 study published in the Journal of Cosmetic Dermatology, facial aging is not just about surface wrinkles; it involves structural volume loss and the weakening of the SMAS (Superficial Musculoaponeurotic System) layer.
Ultherapy Prime is a High-Intensity Focused Ultrasound (HIFU) device that targets this deep SMAS layer, acting as the foundational support for your face. Thermage FLX is a Monopolar Radiofrequency (RF) device that heats the superficial to mid-dermal layers to stimulate collagen. When patients ask for a complete rejuvenation, addressing only one layer often leaves them unsatisfied because aging affects all depths of the skin.

After performing over 5,000 lifting treatments, one pattern we notice is the confusion between these two premium devices. Here is how they compare:
• Ultherapy Prime (HIFU): Focuses ultrasound energy deep into the skin (up to 4.5mm). It excels at lifting heavy tissue, defining the jawline, and reducing jowls. Results typically peak at 3 months.
• Thermage FLX (RF): Delivers bulk heating to the dermis (up to 3.0mm). It is exceptional for tightening crepey skin, improving pore size, and smoothing fine lines.
While both are powerful, we are always honest about their limitations. Ultherapy cannot tighten the very surface of the skin effectively, and Thermage cannot lift deep sagging muscle fascia. This is why combining them into a single session—Ulthermage—creates a 3D rejuvenation effect. Typically, a combined session takes about 90 minutes and requires no social downtime.
What we typically observe is that patients who receive Ulthermage experience a synergistic effect where collagen production is amplified across all layers.
Feature | Ultherapy Prime | Thermage FLX | Ulthermage (Combined) |
|---|---|---|---|
Primary Goal | Deep Lifting | Surface Tightening | Comprehensive Anti-aging |
Target Layer | SMAS Layer (Deep) | Dermis (Mid-to-Surface) | All Layers (Deep to Surface) |
Sensation | Deep, dull ache | Warm, snapping heat | Managed dual sensation |
In our clinical experience, the most common hesitation patients have is pain. However, by utilizing advanced pain management protocols, including targeted local anesthesia or conscious sedation, we ensure the 90-minute procedure is highly tolerable. The longevity of Ulthermage is also superior, often lasting 12 to 18 months compared to 8 to 12 months for standalone treatments.

Gangnam is the global epicenter of aesthetic dermatology, but not all clinics offer the same level of precision. At Seye Clinic, we are proud to be an official Touch Prime clinic. Touch Prime is Merz's latest authentication system, utilizing an NFC tag built directly into the Ultherapy Prime device. This allows patients to verify 100% genuine tips via their smartphone before the treatment begins.
Furthermore, as a clinic led by KOL (Key Opinion Leader) specialist doctors, we understand that Asian and Western facial anatomies require different energy vectors. One specific detail we focus on is preserving facial volume; we meticulously map out "no-go zones" to prevent the hollowed-out look that can occur with improper HIFU application.
When international patients visit us, the process begins with a comprehensive 3D facial analysis. We measure the exact thickness of your fat and dermal layers.
1. Consultation: A specialist doctor designs a customized vector map, deciding the exact number of lines (e.g., 400 lines of Ultherapy) and shots (e.g., 600 shots of Thermage).
2. Preparation: We apply a customized pain management protocol tailored to your comfort level.
3. Treatment: We typically perform Ultherapy first to anchor the deep tissues, followed by Thermage FLX to shrink-wrap the surface.
4. Aftercare: We provide specialized soothing masks and detailed English aftercare instructions.
Our English-speaking team ensures seamless communication, making the premium Gangnam aesthetic experience accessible and stress-free for global visitors.
• Ulthermage combines Ultherapy Prime (deep lifting) and Thermage FLX (surface tightening) for 3D facial rejuvenation.
• The combined treatment targets multiple skin layers, maximizing collagen production and extending results up to 18 months.
• Seye Clinic utilizes the latest Touch Prime NFC authentication to guarantee 100% genuine Ultherapy tips.
• Customized energy delivery prevents volume loss and ensures optimal, natural-looking contours.
Q: What is the Touch Prime authentication system?
A: Touch Prime is the newest authentication system by Merz for Ultherapy Prime. It uses an NFC tag built into the device, allowing you to scan it with your smartphone to instantly verify that 100% genuine, safe tips are being used for your treatment.
Q: How long does the Ulthermage treatment take, and is there downtime?
A: The combined Ulthermage procedure takes approximately 90 minutes. Because both technologies are non-invasive, there is zero social downtime. You may experience mild redness or slight swelling, but you can apply makeup and resume normal activities immediately.
Q: When will I see the final results from Ulthermage?
A: While you will notice an immediate "shrink-wrap" effect from the Thermage FLX, the true results develop over time. Peak collagen production occurs around the 3-month mark, with lifting and tightening effects lasting between 12 to 18 months.
Q: Is the Ulthermage procedure painful?
A: Pain tolerance varies, but Ultherapy delivers a deep ache while Thermage feels like a hot snap. At Seye Clinic, we use customized pain management, including conscious sedation or specialized numbing protocols, ensuring your 90-minute session is comfortable.
