The recommended dosage for treating bunny lines with botulinum toxin is 2.5–5 units of onabotulinumtoxinA (OBTX). The injection technique involves targeting the nasalis muscle within a defined safety zone on the nose, using a 30-gauge needle to inject 1.25 units at each designated point.

To treat bunny lines, the recommended dosage of botulinum toxin is 2.5–5 units of onabotulinumtoxinA (OBTX). The injection technique involves using a 30-gauge, 0.5-inch needle to inject the toxin intramuscularly into the nasalis muscle. The injections are placed within a specific safety zone, which is a diamond-shaped area on the nose. The procedure involves injecting 1.25 units of OBTX at each of the designated points within this zone. Care must be taken to avoid injecting outside the safety zone to prevent complications such as lip ptosis or epiphoria.
