Query: Best sunblock out there!

I have had skin cancer removed, my son and daughter are redheads and my granchildren are fair and light-eyed. I was introduced to this product on a TV show and have purchased it every summer for 4 years. It is the BEST! We can go swimming...at the pool, lake or ocean...and no one gets a sunburn (unless they want to :)I highly recommend Blue Lizard Sunscream!!
