Thermage FLX

Thermage FLX is a monopolar radiofrequency anti-aging device produced by Solta Medical in the United States (5th generation), focusing on non-invasive tightening + full-layer collagen regeneration + long-lasting anti-aging. It is certified by the FDA, CE, and China's NMPA, and is currently the only radiofrequency device approved for use on the upper eyelids.

Core Technology Upgrades

• AccuREP™ Intelligent Energy Calibration: Real-time monitoring of skin impedance, with automatic micro-adjustment of energy for each pulse, ensuring more uniform, safe, and comfortable treatment.
• 4.0 Smart Tip: Larger treatment area, saving approximately 25% of time; vibration + comfort pulse significantly reduce pain, with most patients not requiring strong topical anesthetics.
• Monopolar Radiofrequency (6.78MHz): Heating depth reaches 4.3mm, covering the dermis + superficial SMAS layer for full-layer tightening.

Mechanism of Action (Immediate + Long-term)

1. Immediate Tightening (Immediately after treatment): Radiofrequency heat heats the dermis to 65–75℃, causing immediate contraction of collagen fibers, resulting in tighter skin and clearer contours.
2. Collagen Regeneration (2–6 months): Thermal injury initiates repair, activating fibroblasts to continuously synthesize Type I / Type III collagen, making the skin progressively tighter, smoother, and more elastic.
3. Long-term Maintenance (1–2 years): Increased collagen density stabilizes the results; annual treatments are recommended for maintenance.

Applicable Areas and Benefits

Face

• Improves sagging, blurred jawline, nasolabial folds, marionette lines, and downward displacement of the apple cheeks.
• Lifts contours, tightens lines, refines skin texture, and shrinks pores.

Eyes (Dedicated 0.25cm² Tip)

• Tightens sagging upper eyelids, drooping eye tails, crow's feet, and fine lines under the eyes.
• Improves dark circles and tightens/brightens the eye area.

Neck

• Fades neck lines, tightens sagging skin, and improves turkey neck.

Suitable Candidates

• Aged 25–60, with early signs of aging or mild to moderate skin laxity.
• Blurred contours, increased fine lines, and decreased elasticity.
• Those who do not want surgery/injections and seek natural, long-lasting anti-aging.
• Significant sagging around the eyes, drooping upper eyelids, or prominent crow's feet.

Treatment Process (60–90 minutes)

1. Pre-treatment: Cleaning + application of topical anesthetic for 30 minutes; grid paper applied for positioning.
2. Treatment: Approximately 900 pulses for the face, 200–300 pulses for the eyes; energy level 3.5–5.0 (varies by individual).
3. Post-treatment: Cold compress for 15–20 minutes to soothe redness and burning sensations.

Post-Treatment Care (Crucial! Affects Results)

Within 72 Hours

• Cold Compress: 3–4 times daily, 15 minutes each time.
• Moisturizing: Medical-grade repair masks + ceramide/hyaluronic acid products.
• Avoid High Heat: Saunas, steam rooms, hot baths, intense exercise, and alcohol consumption.

Within 1 Month

• Sun Protection: SPF50+, strict sun avoidance to prevent hyperpigmentation.
• Skincare: No acids, no alcohol, no retinol; use gentle repair products.
• No massage, rubbing, or exfoliation.

Results and Maintenance

• Immediate: Feeling of tightness, slight redness (subsides within hours).
• 1 Month: Reduced fine lines, refined skin texture, gradually clearer contours.
• 3–6 Months: Peak results, with tightening, lifting, and brightening fully visible.
• Maintenance: Lasts 1–2 years; recommended to have a touch-up session every 12–18 months.
