PATIENT QUESTION
How many Ultherapy lines do I need?
SHORT ANSWER
Most full-face Ultherapy treatments in Seoul use roughly 300–600 lines, depending on face size, skin thickness and laxity. More lines are not automatically better; the right depth and placement matter more.
Dr. Yang Jung-hwa, MD — board-certified dermatologist, Seoul National University
The detail
Dr. Yang distributes lines between 4.5 mm (SMAS lift), 3.0 mm (deep dermis) and 1.5 mm (superficial) based on examination. Thin faces may need fewer deep lines to avoid hollowing.
