HOAN Clinic Seoul: A Clear Guide
HOAN Clinic in Seoul: a clear guide before you book
If you are considering aesthetic care in Korea from the United States, a treatment menu alone is not enough. You need to know who will evaluate you, how options are chosen, what recovery may look like, and how the plan fits your flight home. This guide introduces HOAN Clinic with that practical lens.
HOAN Clinic is located in Hannam-dong, Yongsan. Its approach connects aesthetic medicine with an assessment of skin, facial structure, body contour, and—when medically relevant—lifestyle factors. “Slow Aging” does not mean stopping aging. It means building a staged plan around your current condition and priorities.
HOAN Clinic is a physician-led medical clinic at 78 Dokseodang-ro, Hannam-dong, Seoul, using floors 2 through 4. The medical team includes Dr. Lee Sae-ah, Dr. Choi Joon-ho, Dr. Kim Jae-hyung, and Dr. Kim Ha-eun. Testing or treatment is determined only after reviewing your health history and completing a medical consultation.
What does “Slow Aging” mean at HOAN Clinic?
It is not a promise to turn back time. It is a way to understand the current condition of the skin, face, and body, identify what matters most, and then decide whether treatment, observation, or a staged combination makes sense.
What can you discuss during a consultation?
A consultation may cover skin tone and texture, firmness, subcutaneous tissue, facial contour, muscles, and body contour. These categories organize the conversation; they are not a diagnosis or a promise of results.
Tone, texture, and pores
Pigmentation, redness, uneven tone, texture, pores, scars, and hydration.
Firmness, contour, and volume
Laxity, fine lines, facial contour, volume changes, lifting threads, and energy-based options.
HOAN programs
The structure, suitability, and limits of HOAN EXOMIA, HOAN HA LIFT PLUS, and HOAN CELLIX should be explained individually.
Long-term wellness planning
Nutrition, movement, stress, and other lifestyle factors may be considered within the scope of medical consultation when relevant.
Do not choose a treatment based on a program name alone. Share medications, supplements, allergies, medical conditions, pregnancy or breastfeeding status, previous procedures, and expectations. If privacy or having a companion present matters to you, mention it when making your request.
What medical devices are available at HOAN Clinic?
The clinic has confirmed 14 devices: Ultherapy Prime, Sofwave, LinearZ, LDM, Thermage, XERF, Potenza, EMFACE, ONDA, DermaV, REEPOT, QLAS Hybrid, U-Pulse Dual, and LED. Because similar-looking concerns can have different causes, the device, applicator, settings, and treatment area are selected after an examination.
The lineup includes ultrasound and radiofrequency systems for firmness and contour; options for texture, pores, and scars; lasers for pigment or vascular concerns; body applications; and supportive light therapy. Availability does not mean a technology is appropriate for everyone.
No. Appropriate indication, technology selection, and settings matter more. Treatment area, energy level, session count, and recovery can differ even with the same device.
