Under new rules effective next year, sunscreens must protect against both ultraviolet A and B rays and provide a sun protection factor of at least 15 in order to be labeled "broad spectrum," according to Janet Woodcock, director of the FDA's Center for Drug Evaluation and Research. Products that don't meet the standard will be required to carry a warning that they do not protect against skin cancer. "In the past, the words 'broad spectrum' meant nothing," said Darrell Rigel, past president of the American Society for Dermatologic Surgery. "Now, we can tell patients what to look for." Claims of water resistance and SPF will also be subject to higher standards.
