Summary
This study was designed to test if tartrazine, a common yellow food dye, could be rubbed on the skin to make it temporarily transparent. Researchers planned to apply different doses to healthy volunteers and take pictures to see if they could better see blood vessels and other structures under the skin. However, the study was withdrawn before any participants were enrolled, so no results are available.
