O.N Clinic Institutional Overview
Hospital Information and Location
O.N Clinic is located near Gangnam Station in Seoul, the center of aesthetic medicine in Korea. It possesses excellent accessibility and provides the latest medical equipment and a pleasant treatment environment.

- Location: 8th Floor, Mani Building, 428 Gangnam-daero, Gangnam-gu, Seoul (Near Exit 11 of Gangnam Station, Subway Line 2/Shinbundang Line)
- Hours: Weekday and weekend consultations are available, and a night clinic system is operated for office workers.
Treatment Philosophy and Operating System
O.N Clinic's treatment philosophy is based on the three principles of "Hospitable, Safety, and Satisfaction". Beyond simple aesthetic procedures, it aims to provide customized solutions considering each patient's anatomical characteristics.
- Collaboration System: Through collaboration between plastic surgery specialists (Director Oh Myung-jun) and dermatology/aesthetic procedure medical staff (Directors Lee Dong-geun, Park Hee-jin, Oh Seung-min), it provides total care covering from Bone to Skin.
- Designated Physician System: Operating a 100% designated physician system without shadow doctors (surrogate surgery), the doctor in charge is directly responsible for everything from consultation to procedure and aftercare.
- Safety Oriented: Since opening, it claims 0% medical accidents and is equipped with university-hospital grade safety examination systems (3D CT, blood tests, ECG, etc.).
Major Procedures and Programs
Signature Procedure: Angle Shot
This is O.N Clinic's most representative non-surgical contour correction program.
- Features: By excluding Steroid and PPC components, concerns about side effects (skin indentation, menstrual irregularities, etc.) have been minimized.
- Mechanism: It applies the principle of destroying fat cells themselves rather than just reducing their size, discharging them from the body. Through this, semi-permanent effects can be expected.
- Application Areas: Used for unnecessary fat areas on the face such as double chin, buccal fat, and cheekbones, as well as for body line correction.
- 2nd Generation Renewal: Compared to the 1st generation, the volume and ingredient formulation have been strengthened to pursue both fat destruction effects and skin elasticity improvement simultaneously.

Surgical Program: Bone Top Contouring
This is a facial contouring surgery brand conducted through collaboration with plastic surgery specialists.
- DIBA Analysis Method: Standing for 'Detailed Individual Balanced Analysis', this is O.N's unique design system that precisely analyzes the balance of an individual's bone, muscle, and skin to prevent sagging cheeks or double chins that may occur after surgery.
- One-Piece Square Jaw Surgery: Applies a surgical technique that maximizes the frontal effect by separating the cortical bone and mandibular angle as a single piece.
- Revision Surgery Specialization: Operates a revision surgery clinic that analyzes causes of failure in previous surgeries, such as secondary angles (stair-step phenomenon) and non-union, to restore and reconstruct.

Lifting and Skin Care System
O.N Clinic specializes in improving facial contours and skin elasticity by combining surgical and non-surgical methods.
- Equipment Holdings: Possesses numerous latest high-end lifting devices such as Ulthera, Thermage FLX, Titanium Lifting, Sofwave, and Oligio.
- Muse Analysis System: Establishes treatment plans by objectively quantifying skin tone, texture, elasticity, volume, etc., through a data-based skin analysis system rather than relying on intuition.
- Layer-Specific Custom Design: Aims for complex procedures that distinguish between the skin layer (epidermis-dermis), middle layer (subcutaneous fat), and deep layer (SMAS), combining devices and drugs suitable for each layer.

Reputation and Patient Reviews
Quantitative Evaluation

- Director Lee Dong-geun Individual Rating: As the representative director, he holds a rating of 9.5 and over 450 reviews, driving the overall hospital rating.
Qualitative Evaluation (Positive Factors)
- Professionalism in Consultation: Regarding Director Lee Dong-geun's consultation style, dominant evaluations state there is "no overtreatment" and he "explains meticulously while pointing out anatomical structures." Unlike factory-style clinics, the fact that the consultation with the director after the manager's consultation is not formal, and that the director leads the planning, received positive reviews.
- Angle Shot Effect: Despite the absence of steroids, there are numerous reviews stating distinct improvement effects for double chins and cheek fat, and effectiveness for localized fat reduction that does not go away with dieting.
- Facilities and Service: Many opinions mention that the hospital interior is clean and the staff are kind.
Qualitative Evaluation (Negative/Cautionary Factors)
- Individual Differences in Duration: In the case of some thread lifting patients, opinions were identified on platforms like Sungyesa that while the immediate effect after the procedure was good, the maintenance period was shorter than expected. This may be a general limitation of non-surgical lifting, but it suggests the need for managing patient expectations.
- Waiting Time: As it is a popular clinic, it was mentioned that waiting times may occur even after making a reservation.
Trust Management
O.N Clinic is active within Sungyesa's 'Broker Blocking System' and is being verified in an environment where even actual dissatisfied patient reviews are transparently disclosed rather than manipulated reviews. This can be interpreted as an indicator of the hospital's confidence and transparency.
