For example, manufacturers can no longer claim their products are "water-proof" — they can only say they're water-resistant and must note how long they last after coming in contact with water. Similarly, products must be called "sunscreen" rather than "sunblock," as the goods don't actually block ultraviolet rays.
Other changes include a push for more disclosure — on labels, every active ingredient will be listed and products must also note the tests done to ensure sunscreen actually works.
"There is not a day in clinic that somebody doesn't ask me, 'What kind of sunscreen should I use?' This levels the playing field," Theresa Pacheco, a dermatology professor at the University of Colorado Medical School, told the news source. "We know protection against light can protect against cancer, against aging. One of the best ways to keep yourself looking great forever is wearing sunscreen."
The FDA has frequently pushed for transparency with product labels, most recently cracking down on the use of bisphenol A in packaging.
