"It's important for consumers to know that for the purpose of this study, sunscreens were applied to 75% of the body, four times per day for four days -- which is twice the amount that would be applied in what the scientific community considers real-world conditions," said Alex Kowcz, chief scientist for The Personal Care Products Council.
个人护理产品委员会的首席科学家艾利克斯·考茨说：“消费者要知道，研究中防晒霜的使用量——涂抹四分之三的身体面积、每天四次、连涂四天——科学界认为这是现实世界中人们使用量的两倍。”
The council was concerned, she said, that the FDA's study might confuse consumers and discourage the use of sunscreen.
她说，委员会担心，食品和药物管理局的这项研究会让消费者感到困惑，从而让人们停止使用防晒霜。
When going outside, the American Academy of Dermatology recommends applying at least 1 ounce of sunscreen to all exposed skin every two hours or after swimming, including "back, neck, face, ears, tops of your feet and legs. If you have thinning hair, either apply sunscreen to your scalp or wear a wide-brimmed hat. To protect your lips, apply a lip balm with a SPF of at least 15," the academy says, adding that since UV rays are always present, sunscreen should be applied to exposed skin even on cloudy days and in the winter.
美国皮肤科学会建议，外出时每隔两小时或游泳后要在裸露的皮肤上涂抹至少1盎司防晒霜，包括“背部、脖颈、面部、耳朵、脚背和双腿。如果你头发稀疏，应在头皮上涂防晒霜或戴宽檐帽。为了保护嘴唇，应涂抹防晒指数至少15的润唇膏”。学会还补充说，紫外线无处不在，即使在阴天和冬天也应该在裸露的皮肤上涂防晒霜。
There are ways to protect yourself and your family other than sunscreen. Seek shade, especially between 10 am and 2 pm. when the sun is at its hottest, and whenever your shadow is shorter than you. Use protective clothing, such as long-sleeved shirts and pants and a hat with a wide brim, and don't forget the sunglasses.
除了防晒霜以外，还有其他方法可以保护你和你家人的皮肤。当太阳最毒的时候，尤其是在上午10点到下午2点之间，或影子比你短的时候，要到阴凉处躲避阳光。穿防护衣，比如长袖衬衫、长裤或宽檐帽，别忘了还有太阳镜。
"It's seeking shade, using clothes and when necessary using sunscreen," Andrews said, "but not using sunscreen to prolong your time in the sun."
安德鲁斯说：“寻找阴凉处、穿长袖，必要的时候用防晒霜，而不是用防晒霜来延长你在烈日下的时间。”
