Titanium Dioxide vs. Zinc Oxide Sunscreen
Titanium dioxide and zinc oxide sunscreen benefits debated
The use of sunscreen, as many people know, is recommended by dermatologists today for blocking the sun’s harmful ultraviolet rays that are known to cause cancer. However, many people seem confused about what is the best ingredient – titanium dioxide or zinc oxide – when choosing a sunscreen. For instance, some dermatologists recommend zinc oxide while others seem to like the advantages of using sun blocks containing titanium dioxide. Also, there’s a popular view among proponents of sunscreen use that the best sun block product is one that you will use each and every day you are out in the sun. Two types of sun protection According to the American Cancer Society, a sunscreen and a sun block each offer a different method of application and protection. For example, a typical sunscreen is absorbed by the skin while harmful sunlight is then degraded after contact with the zinc oxide contained in the sunscreen. A sun block also contains similar ingredients as a sunscreen – including titanium dioxide and zinc oxide – but the product is designed to sit on the skin’s surface while the chemicals are not absorbed into the skin. The goal of a sunblock is to absorb or reflect harmful rays away from the skin in the same way a mirror reflects light. In addition, both of these chemicals are considered to be nonallergenic and nonirritating.
Sunscreen properties: A Food and Drug Administration fact sheet states that titanium dioxide is derived from titanium that’s explained as a chalky mineral that’s highly reflective. Also, it’s known that titanium dioxide is a non-comedogenic. This means it does not contain oil that can clog the skin’s pores and cause such things as acne. However, the Food and Drug Administration notes one downside of titanium dioxide. It is less effective than zinc dioxide at blocking those long ultraviolet-A rays that are suspected of causing skin cancer. Overall, the jury is still out on what sunscreen ingredient is best. At the end of the day, it’s the customer who must decide what physical sun block is best because both zinc oxide and titanium dioxide are said to offer effective protection against cancer-causing ultraviolet rays.
