Thermage FLX is a world-renowned monopolar radiofrequency (RF) non-surgical lifting treatment — RF energy heats the dermis and subdermal tissue, causing immediate collagen contraction and long-term neocollagenesis for tightening, lifting, and sagging improvement. Suitable candidates include: (1) Mild-to-moderate facial sagging — drooping cheeks, descended cheek fat pads, blurred jawline. (2) Reduced skin elasticity — collagen loss, thinner and looser skin. (3) Fine lines and pores — periorbital lines, nasolabial folds, enlarged pores. (4) Surgery-averse patients — those wanting to avoid facelift risks and downtime. Thermage FLX features single-session visible results, no downtime, and gradual long-lasting effects (1-2 years) — hailed as the ‘gold standard of non-surgical lifting.’ Rappoel Dermatology near Gangnam Station, Seoul, provides Thermage FLX full-face treatment.
Technical Principles of Thermage FLX
- Monopolar RF deep heating: The FLX tip (4.0cm²) delivers monopolar RF energy that penetrates the epidermis to heat the dermis (65-75°C) — collagen contracts immediately upon heating (instant firmness), while subsequent months continue stimulating neocollagenesis (long-term lifting)
- AccuREP intelligent energy optimization: The FLX system monitors skin impedance 500 times per second and automatically adjusts energy output — more uniform and safer per-pulse energy, reduced burn risk, and improved comfort (more comfortable vibration than older Thermage CPT)
- Comprehensive tip design: The 4.0cm² large tip boosts efficiency (about 600-900 pulses for the full face), paired with a 0.25cm² small periorbital tip (eye-specific) and body tips (body tightening) — dedicated tips per area for safety and precision
- Two-phase collagen effect: Phase one (immediate) — collagen contracts on heating, giving an instant firming sensation. Phase two (long-term) — heating triggers an inflammatory repair cascade that continuously stimulates collagen production and remodeling, with progressive improvement over 1-6 months and peak results at 3-6 months
- Single-session results: Unlike lasers requiring multiple sessions, Thermage FLX is designed as a single treatment — with correct energy settings and technique, one session delivers perceptible lifting; most patients need just one, with severe sagging cases adding a session after a year
Treatment Strategies for Different Aging Concerns
- Full-face sagging type (drooping cheeks): Descended cheek fat pads and loose cheeks. Strategy: 600-900 full-face pulses plus jawline and cheek emphasis — firming plus lifting with improved cheek-fat position
- Blurred jawline type: Lax jawline and unclear contour. Strategy: dense treatment along the jawline (mandibular border) plus upper-neck transition — reshaping the V-line contour
- Periorbital aging type (eye-specific tip): Eyelid laxity and periorbital lines. Strategy: 0.25cm² small-tip treatment (eyelids and periorbital area) combined with full-face treatment — safely firming the eye area and improving drooping eyelids
- Nasolabial fold and fine-line type: Deepening folds and facial lines. Strategy: full-face treatment plus fold-area emphasis plus HA filler (for severe hollowness) — Thermage tightening plus filler volume restoration, a dual approach
- Combination type (Thermage plus others): Multiple issues of sagging, fat, and hollowness. Strategy: Thermage FLX full face plus toxin (wrinkles), HA (hollowness), and Onda lipolysis (fat) — combined per need for comprehensive rejuvenation
Rappoel Thermage FLX Protocol
- Consultation assessment (10 min): Evaluate skin laxity, collagen condition, jawline and periorbital aging → confirm suitability for Thermage or combined treatments → design the treatment plan (energy level, pulses, key areas)
- Cleansing and marking (10 min): Full-face makeup removal → alcohol disinfection → mark treatment grids per plan (ensuring uniform coverage) → apply dedicated grid stickers
- Energy test (5 min): Test pulses on the pre-auricular area first → adjust energy per the patient’s heat response → confirm a comfortable and safe energy range
- Full-face treatment (60-90 min): 600-900 pulses grid by grid → vibration comfort mechanism (tip vibration reduces discomfort) → energy progressively from low to high → emphasis on key areas (jawline, cheeks, nasolabial folds)
- Post-care confirmation (5 min): Check skin condition (mild redness is normal) → ice pack for 10 minutes → avoid high temperatures (sauna, hot baths) for 24 hours → enhance moisturizing and sun protection for a week → gradual effects with continued improvement at 1-3 months and peak at 6 months
Thermage FLX full-face treatment takes about 60-90 minutes with a single session, no downtime, immediate return to normal life, and gradual results lasting 1-2 years. Located 3 minutes from Gangnam Station Exit 10, with seamless English and Chinese consultation.
Frequently Asked Questions
What’s the difference between Thermage FLX and ultrasound lifting (Ultherapy)?
Different principles and candidates: (1) Thermage FLX — monopolar RF: volumetrically heats the dermis and subdermis, emphasizing ‘tightening’: improving skin laxity, elasticity loss, fine lines, and pores; suitable for laxity-type aging. Full-face treatment 60-90 minutes, single session, lasting 1-2 years. (2) Ultherapy — focused ultrasound: focuses energy at the SMAS layer (deeper), emphasizing ‘lifting’: targeting fascial sagging and deep contour laxity; suitable for drooping-type aging. (3) Clinical view — they complement each other: those with both laxity and drooping are often advised ‘Thermage tightening plus ultrasound lifting’; at Rappoel, the ‘Onda + Ultherapy’ combo (facial) achieves layered anti-aging. (4) Selection — lax skin, poor elasticity, many fine lines → Thermage FLX first; deep drooping with clearly descending contours → ultrasound lifting first; uncertain patients can consult Rappoel physicians for a laxity-type evaluation.
Does Thermage FLX hurt? How many sessions are needed?
Pain and sessions: (1) Pain — treatment involves obvious heat and stinging sensations (from deep skin heating), but the FLX system’s AccuREP energy modulation and vibration comfort mechanism greatly improve comfort; most describe it as ‘a tolerable hot-prickling sensation’; topical anesthetic or painkillers can be used; 60-90 minutes total. (2) Sessions — Thermage FLX is designed as a single treatment: most patients achieve satisfactory results in one session; those with severe sagging or wanting more pronounced effects can add a second session after 6-12 months. (3) Timeline — immediate firmness on treatment day (instant collagen contraction), progressive improvement at 1-3 months (neocollagenesis), best results at 3-6 months. (4) Rappoel tailors the overall strategy to individual tolerance and aging degree.
How long do Thermage FLX results last? How soon will I see results?
Timeline and duration: (1) Immediate — a firming sensation right after treatment (collagen contraction on heating), with the skin feeling tighter to the touch. (2) Progressive — neocollagenesis continues for 1-3 months, steadily improving facial contours, jawline, and fine lines. (3) Peak — 3-6 months reaches the effect peak, the best observation window. (4) Duration — results last 1-2 years (varying with collagen metabolism, lifestyle, and skincare), after which collagen naturally declines and treatment can be repeated. (5) Habits that prolong results — sun protection (the biggest collagen killer), moisturizing, adequate sleep, balanced diet — well-maintained skin lasts longer. (6) Rappoel follows up at 6 months to evaluate results and recommend maintenance.
What ages and skin types suit Thermage FLX? Any side effects?
Suitability and safety: (1) Age — 30-60 years old all suit, based on aging degree rather than age: ‘preventive tightening’ at 30-40, ‘improvement lifting’ at 40-60. (2) Skin type — all types; no skin-color limitation (unlike lasers, RF does not depend on melanin absorption, safe for dark skin). (3) Side effects — mild redness after treatment (hours to 1-2 days), slight swelling (1-3 days), brief tenderness in a few; extremely rare burns or nerve sensation changes (related to energy settings and technique; Rappoel ensures safety with test pulses). (4) Note — avoid high temperatures and exfoliation for a week after treatment; enhance moisturizing and sun protection. (5) Unsuitable — pregnancy, electronic implants such as pacemakers, infection or open wounds in the treatment area.
What’s the difference between Thermage FLX and a facelift? Which suits me?
Non-surgical vs. surgical: (1) Thermage FLX — non-surgical, single 60-90 minute session, no downtime, gradual results lasting 1-2 years; suitable for mild-to-moderate sagging, those wanting safe improvement without time off. (2) Facelift (SMAS facelift) — surgical, 2-4 weeks recovery, dramatic long-lasting results (5-10 years); suitable for moderate-to-severe drooping wanting one major improvement. (3) Selection — mild-to-moderate laxity → Thermage suffices; moderate-to-severe drooping (obviously hanging cheeks, deep folds, vanished jawline) → Thermage partially helps, but surgery is more dramatic; surgery-averse patients → Thermage remains an excellent ‘delay-surgery’ option. (4) Rappoel honestly evaluates — those suited to Thermage get Thermage; those with too-severe sagging are referred for surgical consultation rather than being pushed toward ineffective treatment.
