Query: WORTHLESS!

Being very fair and living in Phoenix AZ for 25 years, I know about sunburns and sunscreens. I have always been very careful about protecting my kids from the sun. I bought this product because I could not find my favorite sunscreen, Blue Lizard, at a local store. My 13 year old recently received his first EVER severe sunburn while using this product. If I could give this product 0 stars I would. Don't waste your money! I am going back to using Blue Lizard Sunscreen - I found it here at amazon.
