Thermage FLX is a monopolar radiofrequency platform. Published studies report variable and generally modest tightening in selected patients; tip, area, settings, risks, recovery, and expectations require individual assessment. It does not guarantee jawline change or replace surgery or volume treatment.

Results Over Time
Thermage FLX delivers monopolar radiofrequency for non-surgical skin-tightening plans. Many people resume usual activities, while temporary redness, swelling, tenderness, or altered sensation can occur.
01Immediately
Some people notice an early change, but it is not guaranteed. Temporary redness, swelling, or tenderness can occur.
021 Month
Early collagen remodeling begins; subtle firmness continues to develop beneath the surface.
033 Months
Visible lifting and contouring improve as neocollagenesis progresses.
04Following Months
Collagen remodeling and visible response vary by the treatment plan and individual tissue.
05Follow-Up
Response and any future treatment are reviewed individually rather than on a fixed annual schedule.

Thermage FLX Device
The 4th-generation Thermage FLX with AccuREP™ real-time energy calibration and a larger Total Tip, operated by a board-certified dermatologist.
Faster
The Total Tip 4.0 cm² provides a 33% larger treatment area compared with the 3.0 cm² tip, allowing treatments up to 25% faster.
Algorithm
AccuREP™ technology automatically calibrates and adjusts energy delivery for each REP to support consistent treatment across different areas.
Experience
Multi-directional vibration and cooling pulses support a more comfortable, precise treatment while heat is delivered.
Technology
Contact, energy and cooling
Five views of how a Thermage FLX treatment pulse combines tip contact, radiofrequency energy and cooling.
Tip contact
The treatment tip contacts the skin before the pulse begins.
Choose a feature to explore the illustration.
The treatment tip contacts the skin before the pulse begins.
The system cools the treatment tip before delivering radiofrequency energy.
Monopolar radiofrequency delivers heat to tissue. Vibration can accompany energy delivery.
Cooling is also delivered while radiofrequency energy is being applied.
Cooling continues briefly after radiofrequency energy delivery ends.
Cooling during energy delivery is shown separately for clarity. It takes place within the same pulse, not as an additional energy phase.
Treatment Process
01Consultation & Assessment
Skin quality and laxity goals are reviewed in consultation with a board-certified dermatologist.
02Treatment Planning
The dermatologist determines whether tightening should be the first priority or combined with other care.
03Pre-Treatment Briefing
The treatment plan is explained with recovery expectations before the procedure begins.
04Follow-Up Planning
Follow-up planning is discussed based on maintenance goals and a long-term anti-aging plan.
Treatment Results
Clinical photographs from a combined treatment plan that also included Ultherapy. Individual results vary with skin condition, age, and treatment plan.
Recovery & Care
First Hours
Temporary redness, swelling, tenderness, or altered sensation can occur. Follow the clinician's instructions before applying makeup or active skincare.
Day 1 Onward
Many people resume usual activities, but recovery varies. Contact the treating clinic if symptoms are marked, worsening, or unexpected.
Weeks 1–12
Continue normal skincare. Use daily broad-spectrum SPF 30+ to protect newly remodeling collagen from UV damage.
Follow-Up
Review the response before considering future treatment; a fixed annual schedule is not appropriate for every patient.
Frequently Asked Questions
Q.Does Thermage replace fillers or skin boosters?
No. Thermage delivers radiofrequency energy; it does not inject filler or a skin-booster product. Skin firmness, skin quality, and volume loss are different concerns, so treatment for one should not be assumed to replace treatment for another. These options should not be assumed to be directly interchangeable. Choice depends on anatomy, the main concern, exact device and treatment plan, material risks, and recovery; an in-person assessment should come before selection.
Q.Why do some people compare Thermage and HIFU so often?
They are often compared because both are non-surgical energy-based options discussed for skin laxity. Thermage uses radiofrequency, while HIFU uses focused ultrasound; sharing a treatment category does not make their plans or results equivalent. These options should not be assumed to be directly interchangeable. Choice depends on anatomy, the main concern, exact device and treatment plan, material risks, and recovery; an in-person assessment should come before selection.
Q.What is the difference between Thermage FLX and Ultherapy in Seoul?
The main technical difference is the energy source: Thermage FLX uses monopolar radiofrequency, while Ultherapy uses microfocused ultrasound with imaging. This difference alone does not establish which will work better for a particular face. These options should not be assumed to be directly interchangeable. Choice depends on anatomy, the main concern, exact device and treatment plan, material risks, and recovery; an in-person assessment should come before selection.
Q.Is Thermage good for sagging skin and jawline laxity?
Thermage may be considered for skin firmness or mild laxity, but published outcomes vary and are generally modest. It does not guarantee jawline change or replace surgery, filler, or treatment for a different concern; suitability is assessed in person.
Q.How many shots are usually used for Thermage in Seoul?
There is no universal full-face REP count. Confirm the exact tip, treatment area, planned REPs, settings, and included care in an itemized plan after examination; a higher REP count alone does not guarantee a better result.
Q.How long do Thermage FLX results last?
Published studies describe gradual change during follow-up but do not establish one durability or annual retreatment schedule for every patient. Skin findings, area, tip, settings, age, and response differ. Any future treatment should be decided after an individual follow-up assessment.
Q.Is Thermage FLX safe? What are the typical side effects?
Many people resume usual activities quickly, but temporary redness, swelling, tenderness, bruising, tingling, or altered sensation can occur. Follow the treating clinician's area-specific advice. Review the response, recovery, and any adverse effects before deciding whether or when another treatment is appropriate.
Q.How much does Thermage FLX cost at Delight Dermatology in Seoul?
Standard Thermage FLX at Delight Dermatology is in the range of approximately ₩1,000,000 to ₩2,600,000. The final quote depends on tip type (Face / Body / Eye) and the area treated, assessed during in-person consultation. Eye Thermage is quoted separately.
