For years, dermatologists have told us sunscreen protects skin. Now, many people are questioning that advice after an environmental group challenged the safety of many popular brands.
"Patients are confused," said Darrell Rigel, a clinical professor of dermatology at New York University who is a skin cancer researcher. "I've had patients come in and ask, 'Am I harming myself by using it?' I've spent a lot of time talking to people about it."
The latest report comes from the Environmental Working Group, which claims that in an investigation of nearly 1,000 sunscreen products, four out of five offer inadequate protection from the sun or contain ingredients that may pose a health risk.
But dermatologists who reviewed the group's research say the biggest problem is that it lacks scientific rigor. In particular, they are critical of a sunscreen rating system that they say is arbitrary and without basis in any accepted scientific standard.
"What they are doing is developing their own system for evaluating things," said Warwick Morison, professor of dermatology at Johns Hopkins and chairman of the Skin Cancer Foundation's photobiology committee, which tests sunscreens for safety and effectiveness. "Using this scale to say a sunscreen offers good protection or bad protection is junk science." http://www.iht.com/articles/2008/07/23/healthscience/22...
