345 Plastic Surgery is a clinic near Sinnonhyeon Station in Seoul, where board-certified plastic surgeons specialize in facial contouring, lifting and facelift surgery, eye and nose surgery, and skin treatments. The clinic is built on a belief that every face has its own distinct beauty, and that natural, harmonious results depend on accurately understanding each person's facial balance and individual characteristics. The clinic's philosophy takes inspiration from the three basic facial shapes that give it its name: Triangle, Square, and Circle. Rather than pursuing a single, uniform standard of beauty, 345 focuses on preserving each patient's unique features and appeal while refining a more balanced, harmonious facial line. Every treatment plan begins with a one-to-one consultation to fully understand the patient's concerns and goals, followed by a precise analysis that guides an individualized surgical and treatment plan. 345 operates an integrated system in which experienced specialists in each area personally handle consultation, surgery, and aftercare. In facial contouring in particular, the clinic draws on more than 10,000 cases, analyzing each patient's bone structure and facial proportions in detail to create a natural, harmonious line without excessive resection. Its surgeons, with an average of more than 22.6 years of clinical experience, take direct responsibility for care from the first consultation through surgery and follow-up, supported by 3D CT-based precision diagnosis and a systematic safety-management protocol that reinforces both accuracy and safety. For international patients, 345 provides multilingual consultation and a dedicated coordinator system, along with one-stop access to both surgical and skin treatments as part of a medical tourism service. Above all, the clinic's defining difference is a personalized design approach that respects each patient's facial features and individuality rather than applying a uniform standard, in pursuit of results that are natural, refined, and lasting.
