Tallow on its own protects against sunburns, but the the addition of zinc oxide takes it to the next level. Zinc oxide works as a physical barrier for ultraviolet light reflecting and scattering the rays reducing the risk of sunburns, skin cancer, and premature aging. Unlike chemical sunscreens , zinc oxide works immediately upon application and remains stable under sunlight, ensuring long lasting protection. Zinc oxide particles are large enough to reflect and scatter ultraviolet light while being small enough to blend seamlessly into the skin avoiding a white greasy appearance. Zinc oxide is also known for its gentle and non-irritating properties, making it suitable for all skin types.
