Zinc oxide is one of the least expensive, most accessible substances available. You can buy it at any Walmart, grocery store or corner drugstore. Zinc oxide is a powder that does not dissolve in water but instead becomes a paste. It is a naturally occurring but non-organic mineral added to medications and topical treatments and is also an ingredient in substances such as paint, sealant, and adhesive. There are many surprising health benefits of zinc oxide.


1. Zinc Oxide is a Long-Lasting Sunscreen

There are two types of sunscreen: physical and chemical. Chemical sunscreens absorb into the skin and soak up the sun’s harmful rays from within. Zinc oxide, however, is the best-known example of a physical sun screen. It simply provides a waterproof barrier between the skin and the sun, with no irritation and no need to apply over and over. While chemical sunscreens need to be applied every time a person comes out of the water, zinc oxide only needs to be refreshed every 90 minutes or so. Since you can physically see whether it’s there and doing its job, you can reapply when it appears to be wearing off.
