Dr. Kim Jung-su is representative director of DayOne Clinic Gangnam Main Branch and a board-certified family medicine specialist. He previously directed 365MC Sinsa Surgical Center, YEJIMIMO Konkuk branch, and the dermatology department of WONJIN & Evergrande Tianjin Cosmetic Hospital in China.
He is an officially recognized physician for MERZ KOREA (Ulthera, Xeomin, Belotero), GALDERMA KOREA (Restylane), ILOODA (Secret), and VENUS CONCEPT (Venus Viva). He is also a MERZ Aesthetics Key Doctor and APAC Golden Record Award recipient.
His technical strengths are “layered tightening” and “personalized injection planning.” He evaluates laxity at the SMAS layer, deep dermis, and subcutaneous tissue, then selects ultrasound lifting, radiofrequency, combined RF, or thread lifting as needed. For injectables, he designs filler, botulinum toxin, and collagen biostimulator plans based on facial anatomy and dynamic expression to achieve natural, non-stiff contours.
With a family-medicine background, he assesses patients holistically—considering whether lifting and skin-quality treatments can be combined safely and how medical history may affect choices. His experience in China also helps him understand Asian facial structures and the aesthetic preferences of Chinese-speaking patients.
