A company committed to producing sunscreen, Blue Lizard is dedicated to promoting healthy skin and reducing incidence of skin cancer. Each Blue Lizard formula offers more than 30 times your skin's natural protection against UVB rays. Blue Lizard Australian Sunscreen is made with a unique micronized Zinc Oxide that allows the protectant to form an even barrier against UV rays. Other sunscreens are less technologically advanced - they don't blend onto the skin as easily and don't stay on as long. The FDA requires water-resistance testing in 80 minutes of still water. Australian Standards are 240 minutes in whirlpool water. Blue Lizard sunscreens are tested for 240 minutes in whirlpool water. They're three times more water resistant than most other sunscreens.
