Three top non-invasive skin tightening devices in Seoul: Ultherapy (HIFU ultrasound), Thermage FLX (monopolar RF), Inmode Forma (bipolar RF). Different mechanisms, different results.

Thermage FLX (써마지): Monopolar RF tightens collagen across wider area. Better for forehead, cheeks, overall skin tone. $1,200–2,000 full face. Single session, lasts 1–2 years.
