The correct amounts of sunblock advocated by dermatologists is truly staggering. One well-known female dermatologist says that one should apply enough sunblock to the entire body before heading out, such that one would leave a big grease stain on a plastic chair. One recently even recommended applying it like one would frosting to a cupcake! Still others say that for 2 people going to the beach for the afternoon, that that 4-oz. bottle should only last one for just the one afternoon. You can see where this is going with the money that one would be spending, as well as the sheer assault of all this goop on the skin - yikes! Not awfully long ago, it was put out there that a family could expect to spend $1000 on sunblock for the summer. Equals big bucks for the industry!
