Density RF skin tightening is a Jeisys 6.78 MHz radiofrequency session in which each shot fires a deep monopolar sub-pulse, then a shallow bipolar sub-pulse — from ₩690,000 (≈ $493) for 300 shots at Kind Global Clinic Myeongdong, performed personally by co-directors Dr. Lee Wonjin or Dr. Lee Kangin.
The Density RF skin tightening process is built around one engineering idea: layered heating in a fixed order. Every shot from the Jeisys handpiece delivers a monopolar sub-pulse that heats the deep dermis first, followed within the same activation by a bipolar sub-pulse that warms the shallow dermis — mono then bi, never both at the same instant. That 400W sequential hand-off lets the co-director build thermal effect through 2 depth layers in a single pass, which is why Density RF skin tightening suits sensitive or inflammation-prone skin where sustained monopolar-only heat can feel harsh.
A full visit at Kind Global Clinic Myeongdong runs 60 to 90 minutes end to end: consultation, numbing, 300 to 600 shots of sequential RF, then cooling. Both co-directors personally operate the handpiece — no nurse delegation at any step — and the sealed genuine Jeisys tip is shown with its serial number before opening, with the serial recorded on your chart.
