You Jin Jung, MD, is a board-certified dermatologist and the medical director of Gwanggyo First Dermatology Clinic in Suwon, Korea. She trained and later taught at Hanyang University Hospital in Seoul, serving as chief resident and then clinical assistant professor in the Department of Dermatology. Her peer-reviewed research centres on energy-based devices — pulsed-type bipolar and microneedling radiofrequency for pigmentary disorders, acne and facial erythema — published in Dermatologic Surgery, the Journal of Cosmetic and Laser Therapy and Annals of Dermatology. In practice she assesses skin thickness, laxity and subcutaneous fat volume before combining radiofrequency, microfocused ultrasound and microwave lifting into a treatment plan matched to the individual patient.
