This Tallow mixed with shea butter, avocado oil and castor oil, has added Non Nano Zinc Oxide. Non-nano zinc oxide protects skin by forming a physical barrier on the surface, reflecting and scattering harmful UV rays before they penetrate the skin, offering broad-spectrum protection against both UVA and UVB rays. 
Unlike chemical sunscreens that absorb UV rays, non-nano zinc oxide sits on the skin's surface and acts as a shield, preventing the sun's rays from reaching the deeper layers of the skin. 
Broad-Spectrum Protection:
Non-nano zinc oxide effectively protects against both UVA and UVB rays, which are known to cause sunburn, premature aging, and increase the risk of skin cancer. 
Non-nano zinc oxide is considered safe for both skin and the environment because the particles are too large to be absorbed into the body or marine life. 
Zinc oxide has anti-inflammatory properties, making it suitable for sensitive and acne-prone skin 
Non-nano zinc oxide is considered reef-safe, unlike some chemical sunscreen ingredients that can harm coral reefs and marine life.
