07FAQ

Frequently Asked Questions

Q.Does Thermage replace fillers or skin boosters?

No. Tightening, skin quality, and volume are different problems, even if they show up at the same time.

Q.Why do some people compare Thermage and HIFU so often?

Because they are both non-surgical anti-aging treatments, but they are not interchangeable in every face.

Q.What is the difference between Thermage FLX and Ultherapy in Seoul?

Thermage FLX uses radiofrequency to tighten skin from the surface down, while Ultherapy uses focused ultrasound for deeper tissue lifting. A dermatologist often recommends one or both based on your skin laxity pattern.

Q.Is Thermage good for sagging skin and jawline laxity?

Yes. Thermage FLX is particularly effective for overall skin firmness, jawline definition, and collagen remodeling. Results develop over 2–6 months as collagen rebuilds.

Q.How many shots are usually used for Thermage in Seoul?

A full-face Thermage treatment typically uses 600 shots. Your dermatologist adjusts the shot count and energy level based on skin thickness and treatment area.

Q.How long do Thermage FLX results last?

Tightening typically develops gradually over 2–6 months as new collagen rebuilds, and many patients maintain visible firmness for 12–24 months. Duration varies with age, sun exposure, and daily skincare routine. Annual or biennial maintenance is common, with some patients alternating Thermage with Ultherapy on a longer cycle.

Q.Is Thermage FLX safe? What are the typical side effects?

Thermage FLX is FDA-cleared (510(k) K170758, 2017) and CE-marked. Common short-term effects include mild redness for a few hours and brief warmth during energy delivery. AccuREP real-time impedance feedback and Comfort Pulse vibration significantly improve comfort versus earlier generations. Serious effects are rare when performed by a board-certified dermatologist using authentic Solta-supplied tips. Medical history and active skin conditions are reviewed before treatment.

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.

Q.How can international patients book a Thermage FLX consultation?

International patients can request a consultation via the online booking form, or message via Instagram (@delight_gangnam), KakaoTalk, or LINE. On-site interpreter assistance is available for Mandarin Chinese and other languages with prior arrangement. Delight Dermatology is registered with the Korean Ministry of Health and Welfare for foreign-patient services (Foreign Patient Medical Institution Registration #357-15-02460).
