Pick Your Sunscreen

There are 2 main types of sunscreens:
  • physical (mineral or inorganic)
  • chemical (organic)
Physical screens such as zinc oxide and titanium dioxide work by deflecting UV rays. Chemical screens work by absorbing the UV rays instead of the skin doing so.

In the past, physical screens were heavy and had a tendency to "white" you out. This problem has somewhat been solved with micronized nanoparticles. It is recommended that using a sunscreen that contain 3% avobenzone for UVA protection and avoid products with oxybenzone.
