About the procedure
What to know before choosing Thermage FLX
Thermage FLX is available for consultation at Cellin Clinic Hongdae as part of lifting and firmness care. Compared to previous-generation devices, Thermage FLX has a tip area about 33% larger, dramatically expanding the depth and area the energy reaches, while the overall procedure time is shortened by about 25%. Suitability and response vary, so an in-person consultation is required.
The core technology—an auto-adjustment algorithm—measures the patient's skin resistance by area in real time with each shot to inject optimal RF energy, eliminating burn risk and delivering effective energy precisely only to the target layer. You feel the firming tightening first right after the procedure, then it gradually reaches its peak as dense collagen forms over 2-3 months.

FAQ
Frequently asked questions
See whether Thermage FLX fits your goals
Book a Thermage FLX consultation ↓
01Is there a risk of cheek hollowing (fat loss) after a Thermage FLX procedure?+
When performed correctly, cheek hollowing rarely occurs, but atrophy can rarely happen, so Cellin Clinic Hongdae analyzes the skin layers before the procedure and performs a custom-design procedure that precisely adjusts the energy.
02Is there a particular age range most suitable for starting Thermage?+
Thermage FLX is suitable not only for those in their 30s-70s; for those from their late 20s, raising the collagen density of the dermis in advance before aging begins in earnest can be expected to slow the pace of skin sagging later on.
03Does the procedure interfere with daily life?+
There is almost no swelling or bruising right after the procedure, and same-day face washing and makeup are immediately possible.
04Are the procedure device and tip safe?+
Thermage FLX is a device approved by the U.S. FDA and Korea's MFDS, with proven safety and efficacy. In particular, we only use genuine single-use tips that cannot be reused.
