Best possible protection is Blue Lizard. You can usually find this in the drugstore, I know for sure that CVS carries it. They also have a website that you can order from if you need to. They have a baby formula that is fine for the whole family to use if you want to get one bottle that suits everyone. The key ingredient you are looking for in any sunblock is zinc oxide or titanium oxide. It takes a minute to absorb, so you might look a little pasty for about 10 minutes or so. If you start the day with this, you can reapply throughout the day with one of those easy apply continous spray sunblocks. As long as you start the day off with the best possible protection and remember to reapply throughout the day, you should be able to minimize your sun damage. Have a great trip!!
