Sunscreen / Block
Sunscreens work via 2 possible ways: 1) chemical blocks that breakdown the uv rays as they pass through the skin and 2) physical blocks that prevent the uv rays from getting to the skin.
I recommend the physical blocks (zinc
and titanium) because they have a very good safety profile and work very effectively. If you are going to be in the sun - use a minimum of spf
15 - follow product directions.
