It comes in both physical and chemical.
To date, no criteria exist in the U.S. for measuring and labeling the amount of UVA defense a sunscreen provides. However, the FDA plans to introduce UVA standards within the next few years.
The FDA would demand that manufacturers assess the sunscreen’s ability to screen out UVA with a series of tests, then the FDA would assign the sunscreen a 1 to 4 star rating, with 1 star indicating the lowest and 4 the highest amount of UVA protection. Manufacturers whose products did not meet the minimum requirements would have to label their products “No UVA protection.”
Meanwhile, for your skins’ sake, use a sunscreen with an SPF of 15 or higher every day to protect against UVB, along with some combination of UVA-shielding ingredients. Also, be aware that no matter what sunscreen you use, some UV radiation will still get through to your skin. Therefore, always follow a complete prevention program that includes seeking the shade and wearing protective clothing.
If you follow our comprehensive Prevention Guidelines, you can enjoy yourself outdoors while staying protected from both UVA and UVB year-round, whatever the weather, wherever your locale.
