"I am a proponent of the approach advocated by the [American] Cancer Society," said Dr. Martin Weinstock, a professor of dermatology at Brown University and chairman of the American Cancer Society's skin cancer advisory group. "It's called Slip-Slop-Slap. Slip on a shirt, slop on sunscreen, slap on a hat. That's the way to be safe during outdoor activities."
According to Lautenschlager's group, the type of clothing you wear can make a big difference in sun protection factor (SPF). For example, tightly woven, thick garments made of denim, wool or polyester offer the best protection, while cotton, linen and acetate are much less effective, they noted.
In terms of sunscreens, there are two kinds -- inorganic and organic. Inorganic sunscreens work by scattering UV light using zinc or titanium oxides. This type of sunscreen is well tolerated by the skin and produces few allergic effects. It is recommended for children, the study authors said.
Organic sunscreens absorb the UV rays, and are made up of complex organic molecules that are "photoprotective." Organic screens should be put on 15 to 30 minutes before going out in the sun.
