Fig. 4. (A) Pretreatment photograph of Patient 2 with forced upward gaze. (B) One week after injection in Patient 2. The right side (Rt) was the intradermal injection side and the left side (Lt) was the intramuscular injection side. Eyebrow ptosis is more prominent at the mid-to inner eyebrow on the intramuscular side, and this looks like “samurai eyebrow” when the patient attempted an upward gaze (arrows).
