Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Eyelash Length as Measured by Digital Image Analysis (DIA)	Photographs were taken of the eyelashes. Length was measured in millimeters. Data from both eyes were averaged for each participant for analysis.	Baseline
Secondary	Eyelash Thickness as Measured by Digital Image Analysis (DIA)	Photographs were taken of the eyelashes. Eyelash thickness/fullness was assessed across both eyes as an average of the 3 preset areas measured in millimeters squared (mm^2).	Baseline
Secondary	Eyelash Darkness as Measured by Digital Image Analysis (DIA)	Photographs were taken of the Eyelashes. Eyelash darkness (intensity) was measured within the spline (a narrow area approximately 5 pixels wide that bisects the area of interest). Eyelash darkness was measured in both eyes and averaged for analysis using a scale where 0=black and 255=white.	Baseline
