Innovative Technique for Transparent Skin

Researchers have developed a method to make skin transparent using a common food dye, enabling the observation of underlying tissues without invasive procedures. This technique applies a yellow food dye, typically found in snacks like Doritos, which temporarily alters the skin's optical properties. By matching the refractive indices of skin components, light is able to pass through more effectively, allowing visualization of structures beneath the surface. Potential applications for this advancement include improved visibility for medical procedures, such as locating veins or identifying tumors, provided that safety studies confirm its efficacy in humans.
