Does Thermage FLX hurt? | Numbing and anesthesia stated by Seoul clinics

How official Seoul branch websites describe pain during Thermage FLX and the numbing or anesthesia used (numbing cream, how long it is applied, sedation), with sources and check dates.

Direct answer

The official pages of 18 Seoul branches differ: most branches state sleep anesthesia or local anesthesia, others use numbing cream (one page says 20-30 minutes) or offer conscious sedation, and one page says no separate anesthesia is needed; one page says a warm sensation is felt during treatment and it varies by person (checked 2026-11-07 to 2026-11-08). Each branch's statement is listed below; pain varies by person and area, so confirm the numbing method with the branch at consultation.

Data limitations
  • These are statements on each branch's official page checked 2026-11-07 to 2026-11-08, not medical advice; pain varies by person and area.
  • The English text is a reviewed rendering: it keeps the numbing method, application time and what may be felt, and leaves out claims of no pain, comparisons and reassurance; follow each source link for the original.
  • Only the 18 Seoul branches whose official website and medical-institution registry identity match and whose statement was reviewed are listed; branches whose statement mixes in other treatments are left out.
