Bunny lines are the diagonal wrinkles that radiate outward from the nose bridge when you scrunch your nose — caused by contraction of the nasalis muscle, a thin paired muscle that covers the lateral nasal wall from the nasal tip to the nasal bone. In younger patients, bunny lines appear only on active expression; with repeated contraction over years, static bunny lines become visible at rest and deepen alongside glabellar, forehead, or crow's feet wrinkles.
At Kind Global Clinic Myeongdong, co-directors Dr. Lee Wonjin (KR Medical License 143124, Daegu Catholic University College of Medicine, 2022) or Dr. Lee Kangin (KR Medical License 141247) inject Allergan onabotulinumtoxinA (900kDa complex, FDA approved 1991, KFDA approved 2006) at 2-3 injection points per nasal side, targeting the transverse and oblique nasalis muscle heads at a depth of 2-4mm. Standard dosing is 2-5 units per side (4-10 units bilateral) for expression-only bunny lines; 5-10 units per side (10-20 units bilateral) for deeper static lines. The named co-director who consults you injects every unit and documents the lot number, dilution, unit count, and pre-treatment photographs on your patient chart.
Bunny lines botox is typically performed alongside glabella, forehead, or crow's feet Botox as part of a multi-area session, because isolated nasalis relaxation without addressing the glabellar corrugators (which also contribute to nose bridge wrinkling during frowning) may produce asymmetric improvement. Kind Global Clinic co-directors assess the full upper-face expression pattern before recommending whether bunny lines Botox is optimally performed alone or as part of a coordinated upper-face Botox treatment.
