Arm && Interventions

Group	Intervention	Description
Healthy Females	No treatment	Healthy Females

Primary Outcome Measures

Name	Time	Method
Eyelash Length as Measured by Digital Image Analysis (DIA)	Baseline	Photographs were taken of the eyelashes. Length was measured in millimeters. Data from both eyes were averaged for each participant for analysis.

Secondary Outcome Measures

Name	Time	Method
Eyelash Thickness as Measured by Digital Image Analysis (DIA)	Baseline	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).
Eyelash Darkness as Measured by Digital Image Analysis (DIA)	Baseline	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.
