Non-nano zinc oxide refers to zinc oxide particles that are larger than 100 nanometers in size, ensuring they are not absorbed into the skin. Historically, zinc has been used for its medicinal properties for thousands of years, with the ancient Greeks using zinc ores in healing salves. Zinc oxide, as we know it today, began to gain prominence as a skincare ingredient in the 20th century. From a holistic standpoint, zinc is believed to promote balance and healing, being an essential mineral for the body with roles in immune function and DNA synthesis. Non-nano zinc oxide has been favored in the realm of natural skincare and sun protection due to its ability to provide a physical barrier against harmful UV rays without penetrating the skin or bloodstream. This makes it a safer alternative to chemical sunscreens, especially for those with sensitive skin. Its anti-inflammatory properties also make it beneficial for calming redness and irritations, and it's frequently used in creams for diaper rash, eczema, and other skin irritations. Furthermore, zinc oxide has been recognized for its non-comedogenic nature, meaning it won't clog pores, making it suitable for acne-prone skin. With the increasing demand for clean beauty products, non-nano zinc oxide stands out as a champion ingredient, offering effective sun protection and skin-soothing benefits without the concerns of systemic absorption.
