Ultherapy Prime lifts: focused ultrasound reaches the SMAS, the deep supporting layer under the skin, for a jawline, cheeks or chin that have started to sag. Thermage FLX tightens: monopolar radiofrequency heats the dermis to firm the skin and soften fine lines and wrinkles around the eyes.
Beauty Z Clinic Myeongdong, a dermatology clinic 50 m from Exit 6 of Euljiro 1(il)-ga Station, offers both, alone or combined in one package, after a doctor checks your skin. Consultation is available in English, Japanese and Chinese, with booking on WhatsApp or LINE.

Ultherapy Prime and Thermage FLX are each done in one visit, and you can wear makeup straight away, so either fits a short stay in Seoul. Any flush after Ultherapy Prime fades within a few hours, according to the manufacturer. Both rebuild collagen over the following months, so most of the change shows after you are home. Visit a jjimjilbang or sauna before treatment rather than after, since both treatments call for about a week without one.
