My wife and I have been having a small debate about sun pucky. On the one hand, one could simply not use it and try to acclimate to the sun. Tan instead of burn. Wear long sleeves and hats when first going out. On the other hand, one could put on sun pucky and not worry about hats, long sleeves and the like. You fight off the skin cancer from the sun, but you take on whatever comes with the chemicals in the sun pucky. Opinions?
