What It Is
Thermage FLX is a non-surgical skin tightening treatment that uses radiofrequency (RF) energy to stimulate collagen remodeling, improve elasticity, and reduce wrinkles. It is the latest and most advanced generation of Thermage, known for being faster, more comfortable, and more precise compared to earlier versions (Thermage CPT and Thermage NXT).
Thermage FLX works by delivering monopolar RF energy deep into the dermis. This heats collagen-rich tissue to around 55–65°C, which:
➝ Causes immediate collagen contraction → skin looks slightly firmer right after treatment.
➝ Stimulates new collagen growth → leading to progressive tightening over the following months.
Unlike HIFU devices (Shurink, Ultherapy, Doublo) that target the SMAS layer, Thermage works more superficially, making it ideal for wrinkle reduction, skin texture improvement, and overall tightening.
In Korea, Thermage FLX is considered a premium anti-aging solution, often chosen by patients who want a natural, refreshed look without downtime.
Why It’s Done
Thermage FLX is performed for both aesthetic enhancement and preventative anti-aging:
➝ Wrinkle reduction → Smooths fine lines around the eyes, mouth, and forehead.
➝ Skin tightening → Firms loose skin on the face, jawline, and neck.
➝ Contour enhancement → Defines facial features for a slimmer, V-shaped look.
➝ Eyelid rejuvenation → Lifts drooping eyelids (Thermage Eye treatment).
➝ Texture improvement → Refines pores and skin smoothness.
➝ Preventative care → Used by patients in their 20s–30s to delay sagging.
In Korean aesthetics, where subtle, natural youthfulness is prioritized, Thermage is often recommended for patients with mild to moderate sagging who want tightening without dramatic changes.
Alternatives
Thermage FLX is highly effective, but other treatments may be recommended:
- Ultherapy / Shurink HIFU / Doublo HIFU → Ultrasound-based, targets deeper lifting (SMAS).
- Microneedling RF (Scarlet, Sylfirm X) → Combines micro-injury with RF for texture + tightening.
- Thread lifts (PDO, PLLA, PCL) → Mechanical lift with immediate results but some downtime.
- Injectables (Sculptra, Radiesse, Rejuran) → Stimulate collagen from within.
- Laser resurfacing (Fraxel, CO₂ lasers) → Improve wrinkles and texture but with downtime.
In Korea, Thermage is often combined with HIFU devices:
- Thermage (surface tightening) + Ultherapy/Shurink (deep lifting) → Full-face rejuvenation.
- Thermage + Exosome/PN injections → Tightening plus repair and regeneration.
Preparation
Preparation ensures safety and comfort:
➝ Consultation → Korean clinics often use digital skin scanners to measure laxity and wrinkles.
➝ Medical history review → Patients disclose medications, implants, and health conditions.
➝ Avoid blood thinners → Stop aspirin or supplements 5–7 days prior (with medical guidance).
➝ No alcohol or smoking → At least 48 hours before treatment.
➝ Hydration → Well-hydrated skin responds better to RF energy.
➝ Gentle skincare → Avoid retinoids or acids for 3–5 days prior.
In Korea, preparation often includes a hydrating pre-facial or soothing mask, ensuring skin is primed for the session.
How It’s Done
A Thermage FLX session usually lasts 60–90 minutes:
- Cleansing → Skin is cleaned thoroughly.
- Numbing cream → Optional, as Thermage is generally well-tolerated.
- Marking grid → A temporary grid is applied to guide precise energy delivery.
- RF energy delivery →
- The Thermage FLX handpiece delivers controlled RF pulses.
- Patients feel a brief heat + cooling sensation with each pulse.
- Soothing care → Cooling masks or LED therapy are applied post-treatment.
Treatment schedule:
- One session → Provides results lasting 12–18 months.
- Maintenance → Every 1–1.5 years, depending on age and lifestyle.
Recovery
Thermage FLX is known for its no-downtime recovery:
- Immediately after → Skin feels tighter, looks smoother, and has a healthy glow.
- Day 1–3 → Mild redness or swelling in rare cases.
- Week 2–4 → Progressive tightening as collagen production increases.
- Month 2–6 → Peak results, with visibly firmer and younger-looking skin.
Aftercare recommendations:
➝ Apply SPF 50+ daily.
➝ Use gentle moisturizers to maintain hydration.
➝ Avoid saunas, alcohol, or strenuous exercise for 48 hours.
➝ Continue with barrier-strengthening skincare.
In Korea, clinics often provide post-treatment soothing serums, antioxidant ampoules, or exosome masks to extend results.
Complications
Thermage FLX is very safe, but possible side effects include:
➝ Redness or swelling → Temporary, resolves within a few hours or days.
➝ Mild tingling or soreness → Due to heat stimulation, fades in days.
➝ Bruising → Rare.
➝ Fat atrophy (very rare) → Risk is extremely low with the FLX device.
Korean dermatology minimizes risks with precise protocols, advanced equipment, and experienced practitioners.
