Looking for a skin tightening treatment in Korea? If you’re comparing Thermage FLX and Ulthera (Ultherapy), especially in Gangnam Seoul, you’re not alone. These two non-invasive lifting procedures are popular among locals and international patients alike. But which one suits your needs?
In this guide, we’ll compare Thermage FLX vs Ulthera, using expert insight from Yaan Clinic, a top-rated aesthetic clinic in Gangnam specializing in lifting procedures for over 14 years.
What Is Thermage FLX?
Thermage FLX is a fourth-generation radiofrequency (RF) treatment designed to tighten and firm the skin by stimulating collagen production in the deeper dermal layers. It uses a monopolar RF system with precise cooling to deliver energy safely and comfortably.
- Best for: Loose jawline, cheeks, neck
- Technology: Monopolar RF + vibrating handpiece for comfort
- Sessions: Typically once a year
What Is Ulthera (Ultherapy)?
Ulthera (also called Ultherapy) uses micro-focused ultrasound (MFU) energy to target deep SMAS layers — the same layer treated during surgical facelifts.
- Best for: Defined facial lifting (e.g., double chin, brow)
- Technology: Ultrasound-based lifting with real-time imaging
- Sessions: Every 12~18 months depending on age & skin laxity
