Skin aging is a complex process involving genetic and environmental factors. The investigators hope to learn more about how human genes and their function can contribute to skin aging and human health.
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.
