Sunscreens that use mineral filters as the primary active are called physical, inorganic or mineral sunscreens. The active mineral ingredients in sunscreens are zinc oxide and/or titanium dioxide. Zinc oxide is a naturally occurring mineral that is formed from the metal zinc and titanium dioxide is also a naturally occurring mineral that is formed from the metal titanium.
These mineral filters create a physical barrier on the top of the skin. The Mineral filter sunscreen molecules reflect and scatter both UVA and UVB rays from the skin. That's why mineral sunscreens are effective on application. Unlike chemical sunscreens, the mineral filters do not break down and release heat into the skin.
Non-Nano Zinc Oxide and Titanium Dioxide are Safe and Effective
Both zinc oxide and titanium Dioxide are safe and very stable in formula and when exposed to the sun. They are not absorbed by the skin and therefore do not cause allergic reactions. Chemical sunscreens tend to cause more allergic reactions. Noncoated nanoparticles (less than 35 nanometers in diameter) of zinc oxide and titanium dioxide can be toxic to corals, fish and other reef organisms. The safest sunscreen filters are non-nano zinc oxide and titanium dioxide.
Natural Mineral Active Ingredients
Love Sun Body sunscreens non-nano mineral active ingredients are obtained from naturally occurring substances that are formed through geological processes, excluding fossil fuel-derived materials.
