Start with the concern
The decision should begin with the area, tissue characteristics and change you want to discuss.
LOUAVE Lifting Center
Ultherapy vs Thermage FLX: which treatment fits your concern?
Compare two established non-surgical treatment approaches available at LOUAVE Dermatology Clinic in Seoul. Ultherapy and Thermage FLX use different forms of energy, target tissue differently and may suit different lifting, firmness or wrinkle-related concerns.
This comparison is educational rather than a treatment recommendation. The appropriate device, treatment area, settings and sequence must be selected after individual assessment.

Understanding the Difference
01
02
03
They are not interchangeable, and neither is universally better.
Ultherapy and Thermage FLX are both non-surgical, energy-based treatments, but they do not deliver energy in the same way. Ultherapy uses microfocused ultrasound and real-time imaging to plan treatment at selected tissue depths.
Thermage FLX uses radiofrequency energy delivered through a treatment tip to heat selected tissue while incorporating surface-cooling and comfort features. It is commonly discussed for broad firmness and skin-tightening concerns.
Assess depth and skin quality
A lifting-focused concern may require a different approach from broad skin firmness or fine wrinkling.
Select an individual plan
Treatment area, settings, coverage and possible sequencing should be personalised by the clinician.
Technology Explained
Two energy systems, two different treatment strategies.
The technology influences the treatment depth, coverage, sensation and type of concern commonly discussed during consultation.

Compare by Concern
Begin with what you want to improve.
These examples describe common consultation discussions, not fixed treatment rules. Some concerns may involve more than one tissue layer or treatment approach.
Visible Tissue Laxity
Ultherapy may be discussed when the primary goal involves a lifting-focused approach at selected deeper tissue levels.
Common discussion: UltherapyBroad Skin Firmness
Thermage FLX may be discussed when the priority is broad skin tightening, firmness and contour support.
Common discussion: Thermage FLXLower-Face Softness
Jawline softness may involve skin laxity, tissue position, facial volume, muscle or fat and therefore requires assessment.
Individual device selectionEye & Brow Area
Ultherapy may be discussed for selected brow-lifting concerns, while Thermage FLX may be considered for selected eye-area firmness or wrinkle concerns.
Area-specific assessmentNeck Laxity
Both systems may be discussed for selected neck concerns, but treatment depth, coverage and medical suitability differ.
Consultation requiredMixed Concerns
When lifting and skin-firmness concerns occur together, staged or combination planning may be considered.

Treatment Experience
Book Appointment →
Your visit begins with assessment, not device selection.
LOUAVE reviews the treatment area, degree of laxity, skin quality, facial balance, medical history, previous procedures and preferred recovery schedule before recommending treatment.
Consultation & Concern Review
The clinician discusses your priority areas, expected change, previous procedures and relevant health history.
Facial & Tissue Assessment
Skin laxity, tissue position, volume, muscle activity, symmetry and skin quality are reviewed.
Device & Coverage Selection
The doctor determines whether Ultherapy, Thermage FLX, another treatment or no procedure is most appropriate.
Preparation & Treatment
The area is prepared and mapped. Comfort measures, settings and treatment coverage are individualised.
Aftercare & Result Review
Expected responses, precautions and the appropriate time for reviewing gradual changes are explained.
Recovery & Results
Neither treatment should be judged immediately after the procedure.
Early appearance may be influenced by temporary redness, swelling or tissue response. Longer-term changes develop gradually and vary between patients.
Treatment Day
Temporary redness, tenderness, warmth or swelling may occur depending on the device and treatment area.
Early Recovery
Sensitivity, tingling, tenderness or mild swelling may continue temporarily. Follow the clinic’s aftercare advice.
Gradual Change
Lifting or firmness-related changes may become more noticeable gradually rather than appearing immediately.
Individual Review
Additional treatment should be considered only after the response, remaining concern and medical suitability are reviewed.
Which May Suit You?
A general guide before your clinical assessment.
These points describe common consultation pathways. They do not determine individual suitability or guarantee a particular result.
Ultherapy may be discussed when:
- A lifting-focused concern is the main treatment priority.
- Selected brow, lower-face, neck or under-chin laxity is being assessed.
- Real-time ultrasound visualisation is relevant to treatment planning.
- The clinician considers focused treatment at selected tissue depths appropriate.
- You understand that the response develops gradually and varies individually.
Thermage FLX may be discussed when:
- Broad skin firmness or tightening is the main priority.
- Selected facial, eye-area, neck or body concerns are being assessed.
- Radiofrequency treatment is medically suitable.
- Broad treatment coverage is considered appropriate for the concern.
- You do not have an electrical implant or another contraindication identified during consultation.
Can Ultherapy and Thermage FLX be included in the same plan?
A clinician may discuss combining or sequencing treatments when lifting and broad firmness concerns occur together. This does not mean that every patient requires both devices. Treatment timing, areas, energy settings and recovery must be planned individually to avoid unnecessary treatment.
Confirm that two different treatment goals exist
Avoid overlapping treatment without a clear clinical reason
Consider previous procedures and planned recovery time
Review the response before adding further treatment
Frequently Asked Questions
Questions about Ultherapy vs Thermage FLX.
Final recommendations depend on your anatomy, treatment area, medical history and the change you want to discuss.
Is Ultherapy better than Thermage FLX?
Neither device is universally better. Ultherapy and
Thermage FLX deliver different types of energy and may
be selected for different treatment priorities. The
appropriate choice depends on the concern, tissue
characteristics and clinical assessment.
What is the main difference between the two treatments?
Ultherapy uses microfocused ultrasound with real-time
imaging. Thermage FLX uses non-invasive radiofrequency
energy with integrated energy calibration, cooling and
vibration features.
Which treatment is more focused on lifting?
Ultherapy is commonly discussed when lifting-focused
treatment at selected tissue depths is the main priority.
This does not mean it is appropriate for every form of
facial or neck laxity.
Which treatment is more focused on skin firmness?
Thermage FLX is commonly discussed for broad firmness,
tightening and selected wrinkle-related concerns.
Suitability depends on the treatment area and medical review.
Which treatment is more comfortable?
Sensation varies according to the device, treatment
area, settings and individual sensitivity. One patient’s
experience cannot predict another patient’s comfort.
Which treatment has less downtime?
Many patients return to normal activities relatively
quickly after either treatment, but temporary redness,
swelling, tenderness, tingling or other responses may
occur. Recovery differs between individuals.
Can Ultherapy and Thermage FLX be combined?
They may be combined or sequenced for selected patients
when more than one treatment goal exists. The decision
should be made after reviewing treatment areas, timing,
previous procedures and total energy exposure.
How soon will I see the result?
Some early change may be noticed, but both treatments
are generally assessed over time because tissue responses
and visible improvements develop gradually. Timing varies.
Can either treatment replace surgery?
No non-surgical treatment should be presented as an
equivalent replacement for surgery. Patients with
significant tissue laxity may require a surgical opinion
to understand the available options.
Can international patients arrange consultation before arriving?
International patients can share their priority areas,
previous treatment history, medical information,
preferred dates and Seoul travel schedule. Final device
selection and treatment planning are completed in person.

Important treatment information
This page provides general educational information and does not replace an individual medical consultation. Ultherapy and Thermage FLX use different technologies, and neither is suitable for every patient or concern. Treatment areas, settings, comfort measures, session plans, recovery and results vary. Temporary effects may include redness, swelling, tenderness, warmth, bruising, tingling, numbness, sensitivity or discomfort. Less common or more significant complications may include burns, prolonged pain, nerve-related symptoms, skin-surface changes or scarring. Patients should disclose pregnancy or breastfeeding status, active infection, open wounds, electrical or metal implants, medical devices, relevant neurological conditions, previous surgery, injectable treatments, energy-based procedures, medications and other health concerns. Thermage treatment is not appropriate for patients with certain electrical implants. Urgent medical assessment is required for severe, spreading or unexpected symptoms. Results cannot be guaranteed, and the final plan must be determined by an appropriately qualified medical professional.
