Thermage FLX RF Skin Tightening

Treatment Overview & Clinical Mechanism

Thermage FLX at ReYeonK Clinic is the gold-standard 4th-generation monopolar capacitive radiofrequency (6.78 MHz) tightening procedure within our Non-Surgical Lifting & Skin Tightening center. By delivering uniform volumetric heat across the entire papillary and reticular dermis as well as the fibrous septae of the subcutaneous layer, Thermage FLX induces immediate three-dimensional collagen fibril contraction followed by progressive neocollagenesis over 2 to 6 months. The FLX platform incorporates patented AccuREP™ technology, which automatically measures local tissue impedance prior to every single pulse and fine-tunes RF energy output in real time.

Performed 1:1 by Dr. Lee Doochan, Dr. Kim Hyunsu, and Dr. Choi Hyunho using 100% genuine NFC-authenticated Total Tip 4.0 and Eye Tip 0.25 consumables, the procedure balances deep thermal efficacy with patient comfort via pulsed cryogen cooling bursts and multi-directional handpiece vibration. For patients presenting with both dermal laxity and deep SMAS descent, we offer our signature Ulthermage protocol combining Ultherapy (deep SMAS lifting) and Thermage FLX (full-dermal collagen tightening).

Ideal Candidates & Target Concerns

• Diffuse dermal thinning, loss of skin elasticity, and crepey texture across the cheeks and neck
• Enlarged pores, fine perioral lines, and Accordion smile lines requiring dense collagen compaction
• Thin, lax upper and lower eyelid skin suitable for the specialized Thermage Eye Tip
• Patients with thinner facial tissue who want firming without fat volume reduction
• Individuals seeking comprehensive multi-layer rejuvenation via Ulthermage with Ultherapy

Typical Session Duration	50 to 80 minutes (including grid transfer and multi-pass vector passes)
Recommended Course	1 full session every 10 to 12 months
Expected Recovery Window	Immediate return to daily routine; mild warmth or transient pinkness for 24–72 hours

Step-by-Step Procedure Process

1. 1:1 Physician Elasticity & Grid Mapping: Evaluating dermal thickness and applying the temporary Thermage treatment grid.
2. Genuine NFC Tip Verification: Unsealing and authenticating the single-use Solta Medical tip in the patient's presence.
3. Multi-Pass AccuREP™ RF Delivery: Staggered volumetric passes across the whole face followed by vector tightening along tension lines.
4. Post-RF Calming & Barrier Care: Soothing hydration care without excessive ice application to preserve thermal collagen signaling.

Post-Treatment Care & Clinical Safety Notice

• Avoid ice packs or chilled rollers for 48–72 hours so dermal thermal remodeling remains active; wash with lukewarm water.
• Avoid saunas, alcohol, and strenuous workouts for 5 to 7 days post-treatment.
• Apply rich moisturizing creams and broad-spectrum SPF 50+ sunscreen daily.

Individual results vary depending on skin thickness, age, and tissue elasticity. Potential temporary side effects include localized erythema (redness), mild edema (swelling), tenderness, bruising, or transient sensory changes, which typically resolve within a few days to two weeks.

Frequently Asked Questions

Q. How does Thermage FLX differ from Ultherapy Prime?

Thermage FLX uses monopolar radiofrequency to volumetrically heat and densify the entire dermal collagen matrix (ideal for skin laxity, pores, and fine wrinkles), whereas Ultherapy uses focused ultrasound to lift the deep 4.5 mm SMAS fascia. Our Ulthermage program combines both.

Q. How do you ensure comfort during Thermage FLX without compromising energy?

Rather than lowering energy settings excessively, our physicians utilize multi-pass heat stacking, integrated cryogen cooling, and vibration modulation. Reach us at Contact Us to schedule your consultation.
