Treatment Details
Thermage FLX

Treatment description | At Geudaegoun Dermatology Clinic, Thermage FLX treatments are performed directly by TTT Master and MTL doctors, who also train other doctors in Thermage procedures. Thermage FLX uses radiofrequency energy to stimulate collagen regeneration, helping improve firmness and fine lines. |

Recommended for | People concerned about sagging, loss of firmness, fine lines or a less defined jawline / Travelers seeking lifting with relatively little downtime |
Treatment-specific precautions | Washing your face and applying light makeup are generally possible from the day of treatment, making it suitable during travel. Avoid saunas, alcohol and strenuous exercise that day. Results generally develop over 1–3 months rather than immediately. |
Ultherapy PRIME

Treatment description | A lifting treatment that delivers high-intensity focused ultrasound (HIFU) to the SMAS (superficial musculoaponeurotic system), a deeper tissue layer. Ultherapy PRIME uses real-time ultrasound imaging to check skin-layer depth during treatment. Geudaegoun Dermatology Clinic is officially certified by Ultherapy’s manufacturer. |
Duration | Approximately 1 hour 30 minutes–2 hours (including Geudaegoun’s special anesthesia time) |
How long results last | 6 months–1 year (varies by individual) |
Recommended for | People concerned about a double chin, loss of jawline definition, sagging cheeks or nasolabial folds / People wishing to combine it with Thermage to address deeper and more superficial layers together |

Soprano Titanium

Treatment description | Geudaegoun Dermatology Clinic is an officially certified Soprano Titanium clinic and a key-doctor clinic. This lifting treatment evenly warms the skin using three laser wavelengths to help improve firmness and skin tone, with relatively little pain and downtime. |
Duration | Approximately 30 minutes–1 hour |
How long results last | Changes may be noticeable after one session; regular treatments are recommended for maintenance (varies by individual) |
Recommended for | People seeking a lifting treatment with relatively little discomfort or downtime, or looking to improve both firmness and skin tone |
Treatment-specific precautions | Temporary warmth or redness may occur afterward. Avoid saunas and alcohol on the treatment day, and moisturize and protect your skin from the sun. |
Rejuran Healer

Duration | Approximately 1 hour (including numbing-cream time) |
How long results last | At least 3 sessions at 2–4-week intervals are recommended; results last several months (varies by individual) |
Recommended for | People concerned about fine lines, pores, rough skin texture or a weakened skin barrier |

Treatment-specific precautions | Redness, stinging and tiny scabs may occur and settle within a few days. Do not pick the scabs. Avoid washing your face, makeup, saunas and alcohol on the treatment day, and take care to use sun protection and moisturize. |
Pico laser

Treatment description | Geudaegoun Dermatology Clinic was recognized as a Korea Good Doctor for melasma and pigmentation. Pico laser uses short picosecond laser pulses to break down pigment in the skin, helping improve dark spots, freckles and dull skin tone. For melasma, a specialist’s diagnosis determines whether treatment is appropriate. |
Duration | Approximately 1 hour–1 hour 30 minutes (including numbing-cream time) |
How long results last | Multiple skin-tone improvement (toning) sessions at 2–4-week intervals are recommended. Pigmentation can recur due to UV exposure and other factors, so ongoing care is needed (varies by individual) |
Recommended for | People concerned about dark spots, freckles, hyperpigmentation or dull, uneven skin tone (for melasma, treatment is decided after a specialist’s diagnosis) |
Treatment-specific precautions | Temporary redness may occur afterward. Targeted treatment of pigmented areas may cause small scabs that fall off within about a week; do not pick them. Always apply sunscreen afterward and avoid exfoliating products for several days. |
