Sun Safety: The truth about SPF and skin cancer



  • SPF is the product’s sun protection factor, meaning how much of the UV rays are blocked.


  • The lowest recommended SPF, SPF 15, blocks about 93 percent of UV rays.


  • Children and those with fair skin should use an SPF of at least 30.


  • Be generous when applying sun block.


  • Even waterproof sun block must be applied every two hours.
