One group (Bim) applied bimatoprost to each eyebrow daily for 9 months, and another applied vehicle nightly to each eyebrow for 5 months. Subjects in the latter group were re‐randomized to apply bimatoprost (Veh‐Bim Group) or vehicle (Veh Group) daily to each eyebrow for 4 months. The primary end point was investigator‐assessed eyebrow appearance; secondary end points were subject‐reported outcomes.</p> </sec> <sec id="dsu12199-sec-0004" sec-type="section"> <title>Results</title> <p>Investigator assessments showed significant improvements from baseline to 6 (<italic>p</italic> = .002) and 7 (<italic>p</italic> = .005) months for the eyebrows treated with bimatoprost. <italic>p</italic>‐Values for the Veh‐Bim and Veh groups were not significant at any time point. End‐of‐study subject satisfaction with eyebrow fullness or thickness and darkness or color was greater in the Bim group than in the Veh group.
