I found another great mineral based, all natural sunblock that I've used this year and I love it - it's called Mexitan. It's even biodegradable so you can use it in eco-parks. Another item we use is UV protective clothing. Surfers have used rash guard shirts for years but it's just recently that the SPF 150+ protection these shirts provide while you're in the water has been discovered by the rest of the beach going population. They're a great way to protect your skin without sunscreen - you even save on your plastic bottle consumption!
