Unless you have been living on another planet, you know we have to protect ourselves from the sun’s rays. Skin cancer numbers are increasing yearly.  It is imperative that we wear a sunscreen or a sunblock.  Now you may ask….what is the difference between the two?

Well, dear readers, here is the readers digest version of the difference.  A sunscreen is a chemical block. Aesthetically, it can be, but not always, lighter feeling than a sunblock.  You apply it 20 minutes before going out into the sun so that the sunscreen will penetrate the skin.

A sunblock is a physical barrier that protects the skin. Transparent zinc oxide and titanium dioxide are widely used in sunblocks. Our next post will talk about how we at CVD decide which sunscreen to use.
