 Americans can't get sunscreen with cutting-edge ingredients because of a Depression-era law. I'm Sam Whitehead, and this is your KFF Health News Minute. Sunscreens must be tested on animals in the U.S. because of the 1938 statute. That's expensive, and other countries don't require it. That leaves Americans without access to effective products other parts of the world have been using for decades. Still, dermatologists say any sunscreen is better than no sunscreen to protect against skin cancer and wrinkles.
