Should You Stop Using Sunscreen?
It took just one day of use for several common sunscreen ingredients to enter the bloodstream at levels high enough to trigger a government safety investigation, according to a pilot study conducted by the Center for Drug Evaluation and Research, an arm of the US Food and Drug Administration.
根据美国食品和药物管理局下属的药品评价和研究中心开展的一项初步研究，防晒霜中的几种常见成分在涂抹一天后就会进入血液，且浓度高到足以启动政府安全调查。
The study, published in the medical journal JAMA, also found that the blood concentration of three of the ingredients continued to rise as daily use continued and then remained in the body for at least 24 hours after sunscreen use ended.
发表在医学期刊《美国医学会杂志》的这项研究发现，三种防晒霜成分在血液中的浓度在日常使用后持续增加，而且在停止使用防晒霜后，这些成分在人体内至少会滞留24个小时。
The four chemicals studied- avobenzone, oxybenzone, ecamsule and octocrylene- are part of a dozen that the FDA recently said needed to be researched by manufacturers before they could be considered "generally regarded as safe and effective."
研究中涉及的四种防晒霜成分——阿伏苯宗、氧苯酮、依茨舒、奥克立林是食品和药物管理局近日要求制造商调查的12种化学成分中的一部分，以确定它们是否“普遍安全有效”。
Looking through the results tables of the study, one thing about oxybenzone stood out.
研究结果显示, 关于氧苯酮的一点很突出。
Oxybenzone was absorbed into the body at about 50 to 100 times higher concentration than any of these other three chemicals they tested.
氧苯酮被人体吸收的浓度比测试的其他三种化合物中的任何一种高出50到100倍。”
So, should you stop using sunscreen? Absolutely not, experts say. 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.
那么你是否应该停用防晒霜呢？专家说，绝对不行。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。”
