Dr. Don-gyu Han, aesthetic physician and representative director of Rejume Clinic, lecturing at the Laseroptek LEAD Symposium
Dr. Han lecturing at the Laseroptek LEAD Symposium, where he serves as a Key Opinion Leader.

Welcome to The K Beauty Derm. I’m Dr. Han, an aesthetic doctor in Busan, South Korea, and the representative director of Rejume Clinic since 2017. I have practiced aesthetic medicine since 2014, treating thousands of patients with laser devices and skin boosters — including Ultherapy Prime, Density, Titanium lifting, BBL HERO, Rejuran and Juvelook. On this blog I explain Korean aesthetic treatments the way I explain them to my own patients: how they work, who they suit, what they cost in Korea, and what results (and side effects) to realistically expect. No hype, no sponsored rankings — just clinical experience translated into plain English.

His clinical philosophy: real ‘Korean glass skin’ comes from structural regeneration — rebuilding the skin barrier and dermis — not from superficial, temporary fixes. He is known for meticulous hand-injection techniques for skin boosters and customized, multi-layered device protocols rather than one-size-fits-all treatments.
