TropicSport is a silky smooth mineral sunscreen that absorbs fully into your skin, leaving no white residue or "ghosting." TropicSport passes the FDA 80-minute and the Australian 4-HOUR water resistance test. Our sunscreen is truly reef friendly as it does NOT contain Oxybenzone, Octinoxate, Octocrylene or Avobenzone. We contain only two active ingredients, Zinc Oxide and Titanium dioxide, to ensure the safety of the Oceans' reefs. Our sunscreen will NOT go past the physical barrier of your skin and enter your bloodstream.
