原文和译文

Beauty is in the eye of the beholder - but since our survival islargely driven bysexual selection

情人眼里出西施，但因为我们的生存取决于物竞天择

We often attempt to accentuateour features with makeup.

我们常常靠化妆来让外貌更出众。

So what exactly is in makeup products, and should we trust these substancesthat we apply toour bodies?

所以到底化妆品内含有什么，以及我们是否该相信这些我们涂抹在脸上的东西呢？

Could makeup actually be bad for you?

化妆是否其实对你有害呢？

Historically, ancient Egyptians would grind up a mineral substancecontaining primarily lead sulphideto rim②aroundtheir eyes, creating the sultry cleopatralook.

历史上，古埃及人会将含有硫化铅的矿物质磨碎,涂抹于眼部周围，制造出埃及艳后的妆容。

Little did they know that lead is a potent neurotoxin, which can lead to learning and behavioural difficulties in children and decrease fertilityin both men and women.

但他们不知道的是铅是一种神经毒素，可以导致幼童学习和行为困难且降低男性及女性的生产力。

Later, In 1891, creams, lotions, and blushcontaining compounds of the radioactive element radiumwere also sold to women in Europe, promising a youthful glow - until the harmful effects of exposure to radioactivity was discovered, that is.

后来，在1891年，含有放射性元素镭的化合物的霜、乳液和腮红供应给了欧洲的女性提倡更年轻的妆容，直到有人发现放射性素镭对人体造成负面伤害，才停止。

But makeup has come a long way, and now there are only trace③ amounts oflead found in our products.

但是化妆品历经多年进化，现在产品内只有少量的铅。

Lead is found in nature and is therefore an unintentional contaminant from the manufacturing process.

铅来自于大自然，所以制造过程中会无意间造成污染

An FDA study of 400 tubes of lipstick found concentrations ranged from 0.026ppm to 7.19ppm of lead, which is under Health Canada's limits of 10ppm.

一份 FDA 的报告指出有 400 个口红被发现含有 0.026ppm 到7.19ppm的铅，低于加拿大卫生部的条件限制的 10ppm。

Lipstick is about 47% oils, 36% pigments, 17% waxesand 5% other components including preservatives.

口红大约有47%的油、36%的颜料、17%的蜡及5%其他东西像是防腐剂。

The oils are primarily castor oils, extracted froma bean which contains the protein ricin – one of the most toxic substanceson this planet which has been used as a biological weapon.

口红的油是蓖麻油，从一颗含有蓖麻蛋白的豆中萃取出来的也是其中一个被用来制造生物武器的有毒物质。

However, the process of extracting castor oil involves heating, therebydenaturing ricinand rendering it inactive.

但是，萃取出蓖麻油的过程包含加热的动作，使蓖麻毒素变质并处于非活动状态。

Pigmentsnow use syntheticdyesdue to cost and production efficiencies, although traditionally, red pigments were extracted from dried and crushed cochineal insects.

颜料为了节省成本和提高制作效率，现在都是用合成染料。虽然传统来说，红色的颜料是从死掉的胭脂虫中萃取出来的。

Some blue pigments are created with ferric ferrocyanide.

Cyanide is extremely deadly, however in this compound structure, cyanide has a very strong bond to iron.

氰化物则有致命的危险性，但是制作的过程会让氰化物与铁产生强而有力的连结。

As a result, it is unable to come apart to poison us by eyeshadow.

因此，氰化物无法脱离铁留在眼影里来毒害我们。

When it comes to mascara, we recommend tossing the tube④ after three months of opening.

说到睫毛膏，我们建议打开后三个月就要丢弃。

Harmful bacteriaof the Streptococcus species and certain fungiwere discovered thriving in 36.4% of mascara tubes.

36.4%的睫毛膏被发现含有链球菌中危害的细菌和特定的箘。

And this is especially important for contact lens wearers, as bacteria can easily enter the micro-abrasions caused by the lens itself.

这对戴隐形眼镜的人来说，更是重要，因为细菌可以轻易地进入隐形眼镜造成的微小磨损处。

Parabenshave been a big concern as well as they're in a myriad ofcosmetic products.

对羟基苯甲酸盐一直都具争议性，因为许多化妆品都有这个东西。

Paraben works by mimicking⑤estrogenand binding to estrogen receptors.

对羟基苯甲酸盐会模仿雌激素和雌激素受体结合。

This can cause the expression of genes to be changed and communication within cells to be altered.

这可以导致基因改变且改变与细胞的沟通。

Additionally, it can lead to the growth of certain breast cancer cells.

总体来说，这可以导致乳癌的癌细胞的滋长。

However, many products are switching to paraben free - and a lot of research still needs to be done in order to reach any definitive conclusions.

但是，很多产品现在都改成不含对羟基苯甲酸盐。还需要未来更多的研究来让我们对化妆品的人体的影响有明确的结论。
