The use of nanoparticles in sunblock is one of the most common applications of nanotechnology, yet most consumers don't know about it due to the lack of regulatory guidelines.
Nanoscale particles in sunblock are invisible because they are smaller than the wavelength of visible light.
Current research shows that sunblocks containing nanoparticles are generally safe to use on healthy skin.
