When it comes to sun block, we use entirely too much. But some is necessary, especially on kids and on sensitive areas like the face and shoulders. The best sun block on the market is Beaver-43. It comes in a small 2-ounce tube (a little goes a long way). I like to mix a little of it in my hand with regular suntan cream for my sensitive areas.
Summer without Beaver-43, Cataplex F, and Calcium Lactate? Not for me.
