Sunblock And Sunscreen Facts

Did you know there are two types of sunblock? I did not know that until I read an interesting article by the Univeristy of California which reports the two major types of sunblock are:

• Chemical sunblocks, which "work by absorbing the energy of UV radiation before it affects your skin."
   
•  Physical sunblocks, which "reflect or scatter UV radiation before it reaches your skin. Some sunblocks combine both chemical and physical sunblocks."

 And here are a few "little-known facts" about sunblock:

 

• Each numeric unit in the SPF ratings indicate 20 minutes of protection before burning would occur. Therefore, an SPF 1 offers 20 minutes of protection. An SPF-10 offers 200 minutes, and so on.
   
• A sunblock's actual protection varies based on your own skin's sensitivity to burning. 
   
• Products with an SPF-rating of 60 or higher are considered sunblocks. Those with an SPF-rating of less than 60 are classified as sunscreens.
