When considering lifting procedures, the most frequently asked question is "Would Ultherapy Prime or Thermage FLX be better for me?" To give you the straightforward answer: the two procedures are not a matter of superiority or inferiority, but rather work on different skin layers and serve different purposes altogether. Ultherapy Prime is a 'lifting' procedure that focuses energy down to the SMAS fascia layer to pull up sagging facial contours, while Thermage FLX is a 'tightening' procedure that delivers radiofrequency energy evenly across the dermis to improve elasticity and skin texture. Your choice depends on which concern is greater, and it is more rational to receive professional medical consultation first rather than make a decision without skin diagnosis.
In Gangnam, Ulthera vs Thermage Ultimately Comes Down to 'Which Layer to Tighten First'
When comparing the two procedures, the first thing to clarify is the depth at which energy reaches the skin. Ultherapy Prime uses high-intensity focused ultrasound (HIFU) to precisely focus energy at thermal coagulation points (TCP) at depths of 1.5mm, 3.0mm, and 4.5mm. In particular, the 4.5mm depth corresponds to the SMAS fascia layer, which is considered the key to facial lifting, and direct stimulation of this layer can be expected to lift sagging cheeks, double chin, and blurred jawline.
In contrast, Thermage FLX delivers radiofrequency (RF) energy broadly and uniformly across the dermis. It works to shrink collagen fibers and promote fibroblasts to generate new collagen synthesis, thereby increasing skin elasticity itself and improving fine wrinkles and skin texture. Reports from Maeil Shinmun also distinguish Ultherapy as a lifting procedure that improves sagging areas, and Thermage as a tightening procedure that enhances elasticity to prevent sagging.
To summarize, here's the breakdown:
| Category | Ultherapy Prime | Thermage FLX |
|---|---|---|
| Energy Type | Focused Ultrasound (HIFU) | Radiofrequency (RF) |
| Primary Depth of Action | 1.5 / 3.0 / 4.5mm (includes fascia layer) | Throughout Dermis (~2–3mm) |
| Main Purpose | Sagging Correction·Facial Contour Lifting | Elasticity Improvement·Skin Texture·Fine Wrinkles |
| Representative Concerns | Cheek Sagging, Double Chin, Blurred Jawline | Reduced Skin Elasticity, Fine Wrinkles, Skin Texture |
Clinically, both procedures have respective advantages and disadvantages, so medical information platforms such as Doctor Now recommend determining "which procedure suits my skin better" together with medical professionals rather than "which procedure is better." If sagging and double chin correction are primary concerns, Ultherapy Prime may be relatively suitable; if overall skin texture, elasticity, and fine wrinkle improvement are priorities, Thermage FLX may be more fitting. However, it is important to make a decision only after skin diagnosis.
The Principles Behind Both Procedures — Energy Type, Depth of Action, and Timing of Effect Appearance
Ultherapy Prime: Stimulating the Fascia Layer with Focused Ultrasound
Ultherapy Prime uses HIFU technology that focuses ultrasound energy at specific depths without damaging the skin surface. According to Ultherapy official materials, heat of 60–70°C is generated at the thermal coagulation point (TCP) where energy is focused, simultaneously denaturing and contracting existing collagen fibers while inducing new collagen synthesis. Effects are more pronounced at 2–3 months post-procedure than immediately after, with gradual improvement continuing through 6 months. Downtime is minimal, though warmth and tingling sensations may occur during the procedure.
Thermage FLX: Evenly Heating the Entire Dermal Layer with Radiofrequency
Thermage FLX uses RF energy to uniformly heat the dermis and subcutaneous tissue, promoting collagen contraction and new collagen formation. According to clinical data, the device measures skin resistance with each pulse and delivers energy safely, making it applicable even to thin and sensitive areas like the eye region. Effects appear gradually after the procedure, with collagen remodeling progressing over several months, and the duration of effectiveness varies individually.
What If Both Procedures Are Combined
Since the depth of action differs, combined treatment is reported to offer synergistic benefits for multiple skin layers. Sports Korea/Nate News mentions complex effects from combining both procedures, and related clinical data report that average pain scores after combined HIFU and RF treatment were below 5 points (on a 10-point scale), with daily activities resumable the next day. However, energy intensity and procedure sequence must be designed by medical professionals following skin diagnosis.
| Effect Onset | Ultherapy Prime | Thermage FLX |
|---|---|---|
| Immediate Change | Mild lifting sensation (varies individually) | Gradual elasticity sensation after erythema |
| Peak Effect | 2–3 months post-procedure | Several months post-procedure |
| Continued Improvement | Up to 6 months | Progresses over several months |
| Downtime | Minimal | Minimal |
How Shinyu clinic Approaches Ultherapy Prime and Thermage FLX
In lifting procedures, verification of genuine product use and procedural design is as important as device performance. At Shinyu clinic, where the director personally handles procedures carefully, verifies genuine products and correct dosages, and operates transparent fixed pricing, QR-authenticated tip boxes are directly opened in front of patients during Ultherapy Prime and Thermage FLX procedures. With customized lifting design for each patient, procedures are designed based on diagnosis of skin condition by layer rather than on shot count alone.
Specifically, the procedure at Shinyu clinic proceeds as follows:
— Stage 1 · Diagnostic Consultation: By checking skin thickness by layer, sagging pattern, and fat distribution, the direction is determined among Ultherapy Prime alone, Thermage FLX alone, or Level Lifting Package.
— Stage 2 · Genuine Product Verification: QR code authentication for Ultherapy Prime and new tip verification for Thermage FLX are directly performed in front of the patient.
— Stage 3 · Director-Performed Procedure: From consultation through procedure to finish, the director personally handles everything 1:1 in a private single-room environment, not in a factory-style system.
— Stage 4 · Sleep Anesthesia Option: For those sensitive to pain, sleep anesthesia can be chosen. With sleep anesthesia, an anesthesiology specialist remains in the treatment room to monitor safety.
— Stage 5 · Fixed Pricing Guidance: Procedures proceed at pre-announced fixed prices with no additional costs after treatment. For example, Ultherapy Prime 300 shots at 790,000 won, Thermage FLX 300 shots at 1,040,000 won, etc., with pricing transparently disclosed.
Before Ultherapy Prime and Thermage FLX Treatment, Please Verify These Points
Both procedures are non-invasive treatments with verified safety, but pre-treatment confirmation may be necessary depending on skin condition and physical health.
Please confirm with medical professionals before treatment
— Those with thin facial fat layer or concerned about cheek hollowing: According to HiDoc materials, due to HIFU procedure characteristics, when fat layer is thin, there is potential risk of cheek hollowing side effects, requiring careful adjustment of energy intensity and tip selection.
— Those with metal implants in treatment area (prosthetics, metallic fixation from thread lifting, etc.): Radiofrequency energy procedures must definitively review the presence or absence of metal implants in the body beforehand.
— Those who are pregnant or breastfeeding: Procedures using thermal energy are not recommended during these periods, and it is safer to determine procedure timing after consultation with medical professionals.
— Those with recent skin inflammation, wounds, or filler treatment areas: It is good to confirm recovery status with medical professionals before treatment.
Post-Treatment Lifestyle Management for Effect Maintenance
According to clinical data, stimulation can be minimized through appropriate energy settings and tip selection for thermal energy non-invasive procedures. Additionally, Medical Today materials guide that thorough sunscreen use after treatment, sufficient hydration, and regular lifestyle habits help maintain lifting effects.

Ultherapy Prime and Thermage FLX, Frequently Asked Questions
Q1. Which hurts more, Ultherapy Prime or Thermage FLX?
Since both procedures use thermal energy, you may feel tingling or pricking sensations during treatment. Generally, Ultherapy Prime causes warmth and pain sensations when energy concentrates, while Thermage FLX tends to involve relatively even warmth lasting throughout. Those sensitive to pain can choose sleep anesthesia for more comfortable treatment, and with sleep anesthesia, an anesthesiology specialist remains in the treatment room.
Q2. Can both procedures be done together on the same day?
Yes, since they work at different depths, both procedures are often combined on the same day. Shinyu clinic operates a Level Lifting Package combining Ultherapy Prime and Thermage FLX. However, skin condition, energy intensity, and procedure sequence must be designed by medical professionals after diagnosis, and same-day combination may vary depending on individual skin condition.
Q3. Is Eye Thermage different from regular Thermage FLX?
Eye Thermage uses Thermage FLX equipment but with an eye-specific tip (eye tip). Thermage FLX is applicable to thin and sensitive eye skin thanks to its method of measuring skin resistance with each pulse and delivering energy accordingly, and is specialized in improving fine lines and sagging around the eyes. It's also available as an eye elasticity package (Eye Thermage + Rejuran Eye + Wrinkle Botox), so please take note.
Q4. When do effects appear, and how long do they last?
According to Ultherapy official materials, Ultherapy Prime shows the most noticeable effects at 2–3 months post-procedure with gradual improvement continuing through 6 months. With Thermage FLX, collagen remodeling progresses over several months, and you'll gradually notice elasticity changes. For both procedures, the timing of effect appearance and duration of effectiveness vary individually depending on skin condition, lifestyle, and post-procedure care.
