Rhinoplasty Gangnam
Welcome to Onyx Plastic Surgery.
Onyx Plastic Surgery is a rhinoplasty-focused clinic located near Gangnam Station (Exit 12) in Seoul. We believe beauty should never be overdone — we look for the nose shape that matches your facial proportions and impression, not simply a higher nose. At Onyx, the standard is always your face.
Every rhinoplasty is planned on a "structure first, shape next" principle. With 3D CT diagnosis and 3D virtual surgery, we analyze your nasal structure before surgery, build a stable support framework with your own cartilage, and then refine a natural line that lasts.
Our chief surgeon personally handles your consultation, surgery, and aftercare, and every procedure is performed with a board-certified anesthesiologist, operating-room CCTV, and an emergency power system (UPS) — because at Onyx, safety is a standard, not an option.
If you have any questions, please contact us at +82-2-557-8883 or through KakaoTalk consultation.
OUR DOCTORS

Board-Certified Plastic Surgeon
Chief Director Yoo Geon-un
| Dr. Yoo Geon-un’s Treatment Philosophy
"Completing your own natural beauty with care that never misses the smallest detail."
Dr. Yoo believes a good nose is one that fits the face it belongs to. Rather than following a single trend, he designs each nose around the patient’s facial proportions, skin condition, and existing tissue — and focuses on structural strength so the result stays stable over time.
From the first consultation through surgery and follow-up care, Dr. Yoo personally takes responsibility for every step, so each patient’s needs are reflected in the final result. Honest consultation, meticulous surgery, and systematic aftercare are the promises Onyx keeps.
