这里是科学美国人——60秒科学系列,我是克里斯托弗·因塔格里塔。
You hear a lot about how what you eat will affect your microbiome. Probiotics. Prebiotics. Stuff like that. But your skin is swarming1 with microbes too—and the grooming2 products you use might affect what's living there. That's according to a study in the journal BMC Biology.
你听过很多有关食物如何影响你的微生物群的说法。微生物群包括益生菌和益生元等。但你的皮肤也布满了微生物——你使用的护肤品可能也会影响那里的微生物。这是发表在《BMC生物学》期刊上的一项研究得出的结论。
For their tests, researchers recruited six men and six women. The volunteers left their skin alone for the first three weeks except for a light body wash. Then, for the next three weeks, the participants applied3 a modern skincare arsenal4: sunscreen and skin lotion5, antiperspirant and foot powder. Finally, the volunteers returned to their usual routine, whatever it was for each person, for another three weeks.
研究人员招募了6名男性和6名女性进行测试。除了使用少量沐浴露外,志愿者在前三周不使用任何护肤品。在接下来的三周,参与者使用了现代护肤套装:防晒霜、乳液、止汗剂和足粉。最后,志愿者在接下来的三周里恢复自已的日常护肤习惯,无论每个人的习惯为何。
Throughout that time the scientists swabbed the volunteers' faces and forearms, armpits and feet. Then they did chemical and genetic6 analyses of the samples. The lotion and sunscreen did not appear to alter the microbiome. But they found, counterintuitively, that the antiperspirant and foot powder actually boosted the diversity of microbes in the armpits and in between the toes—perhaps because those products change nutrient7 and moisture levels and thus create conditions that foster a wider variety of tiny occupants.
在这段时间里,科学家擦拭了志愿者的面部、前臂、腋窝和脚。之后,他们对样本进行了化学和基因分析。乳液和防晒霜似乎并未改变微生物群。但反直觉的是,他们发现,止汗剂和足粉实际上增加了腋窝和脚趾间的微生物多样性——可能是因为这些产品改变了营养和湿度水平,从而创造了条件,培养了更广泛的微小居住者。
The researchers also found that different skin care routines altered the types of hormones8 and pheromones present on the subjects' skin. And they hypothesize that someday, personalized skin-care recipes could be tailored to individuals to alter our pheromones in a systematic9 way, thus making us more attractive to others. Or less attractive, should anyone need to lessen10 their kavorka. (Seinfeld clip: "Yes, kavorka." "Kavorka?" "It is a Latvian word which means 'the lure11 of the animal.'")
研究人员还发现,不同的护肤程序会改变受试者皮肤上存在的激素和信息素类型。他们假设,未来某天,个人可以定制个性化的护肤配方,以一种系统的方式改变我们的信息素,从而使我们对他人更具吸引力。或者减少吸引力,如果有人需要减少他们的诱惑力的话。(《宋飞正传》片段:“对,诱惑力。”“Kavorka?”“这是拉脱维亚语,意思是‘动物的诱惑力’。”)
