Dermatologists warn tanning oils increase UV exposure and skin cancer risks while providing minimal protection.

A refractometer is a device used to measure the refractive index (n) of a substance. In this article, we discuss what a refractometer is and how it works, the different types available and their ...

What if you could change the refraction index of skin? If you could prevent the normal scattering at the interface, you could reveal the structures underneath, effectively rendering skin transparent.
