Yonsei Line Clinic

About the clinic

Yonsei Line Clinic is an aesthetic clinic on the fourth floor of Is Tower at 101 Teheran-ro, Gangnam-gu, between Gangnam Station Exits 11 and 12. Its official programme focuses on skin ageing, facial firmness and contour, injectable treatments and medical weight management. Director Seong-Hwan Ahn is identified on the clinic’s medical-team page.

Its lifting menu distinguishes XERF radiofrequency treatment, Ultherapy and thread lifting. Injectable options include botulinum toxin, fillers such as Juvederm, Skinvive and individually planned skin-booster care. Potenza, skin-condition consultations and neck-wrinkle care are separately listed. These are different procedures with different treatment areas and planning needs; the device, product and combination should be confirmed for the intended visit.

The clinic also publishes medical-slimming and hair-care programmes, MiraDry care, and upper- or lower-eyelid consultations. Its website separates these from its skin-lifting programme. Before an appointment, identify the main concern and any earlier procedures so the clinic can advise which consultation to arrange and what follow-up may be needed.
