Recently Neutrogena came out with a sunscreen with helioplex in it and LRP has come out with ANTHELIOS SX. Which is recommended or better? I am using the Citrex from the recommended list in the book. How do we know if Dr.B would prefer one of these instead, has anyone read any of her updates on sunscreens? I have a bad habit of always thinking there is something better out there since these products have been released since the book. Any help would be appreciated
