physical sunscreen

Is this the holy grail of SPF?

Summer’s here and that means it's the easy season to apply sunscreen every day.  With longer daylight hours and more time spent outside, most of us are quick to include it as part of our morning routine.
 
However, this often feels like a chore thanks to product formulation.  When I’m sitting on the beach, a hat can hide the white glow left by physical sunscreens.  And the sticky feeling on my limbs after application is just about bearable, but I'm sure it causes more sand to stick to me.
