Biospecimen Retention:   Samples With DNA

Blood and skin samples


Estimated Enrollment: 120
Study Start Date: May 2010
Estimated Study Completion Date: December 2013
Estimated Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)
Groups/Cohorts
Healthy females aged >=18
Healthy female volunteers of skin type I or II

Detailed Description:

This study includes answering a survey on prior sun exposures, donating two small pieces of skin (4mm each), one blood draw, complexion analysis, photographs, and non-invasive tests such as skin surface lipid analysis. Your blood and tissue will be sent for DNA analysis and gene expression profiling.
