Broad spectrum sunscreen is a type of sunscreen that protects the skin from both UVA (ultraviolet A radiation) and UVB (ultraviolet B radiation) rays. UVA rays are responsible for premature aging, while UVB rays cause sunburns and most skin cancers. Before going out into the sun, it is important to double-check that the sunscreen meets the FDA requirements and is labeled as broad spectrum. The FDA requires sunscreen products to go through a battery of tests to prove they protect from all UVA and UVB rays to be labeled as broad spectrum. It is important to note that even with a high SPF (sun protection factor), if a sunscreen isn’t broad spectrum, it won’t be protected from all UVA rays. Therefore, it is recommended to choose a broad spectrum sunscreen with at least SPF 30 if you are spending an extended period in the sun. Broad spectrum sunscreens include combinations of ingredients that protect from both types of rays, such as zinc oxide, octinoxate, octisalate, and titanium dioxide. Wearing broad spectrum protection every day, even on cloudy days or days you’ll spend inside, is the key to keeping skin healthy and reducing the risk of skin cancer.
