First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aimed to see if tartrazine, a common food dye, could make skin temporarily transparent in healthy adults. Researchers planned to apply different doses to the back, stomach, and forearm and take photos every 5 minutes. However, the study was withdrawn before any participants were enrolled, so no results are available.
