Applying Sunblock - Visible vs Ultraviolet Light 

Seeing how the lotion has different visual properties in different light - via Life Pixel

Sunblock being applied to face in visible light & ultraviolet UV light. As you can see this sunblock absorbs UV light rays and therefore appears to be black in the UV only video. In visible light it looks like ordinary lotion.

You can see the video version at Life Pixel here (scroll down to video)

Neato.
