专家揭示十大洗澡误区，你洗对了吗？

Washing your face removes many bugs from the surface of our skin, particularly if you use cleansers containing alcohol as this kills bacteria.
洗脸会去除皮肤表面的许多细菌，若你使用含酒精的洁面产品就更加如此，因为酒精会杀死细菌。

Most cleansers also contain soap, and this reduces the amount of oil in our skin, which loosens the bacteria’s hold — so they fall off, explained Hugh Pennington, an emeritus professor of bacteriology at the University of Aberdeen.
阿伯丁大学细菌学荣誉教授休·彭宁顿解释说，大多数洁面产品也含有肥皂，肥皂会减少皮肤上的油脂，减小细菌的附着力——所以它们会掉下来。

This cleanliness is short-lived, as the layer of bugs rebuilds itself within about 20 minutes.
这种清洁力维持时间非常短，因为细菌层在20分钟之内就会再次形成。

The problem is that we have bacteria on our hands, and when we touch our faces, as we inevitably do, many of the bugs that have adapted to live on moist surfaces such as our face will quickly be transferred back.
问题是，我们手上有细菌，当我们触摸脸时（我们不可避免会这样做），很多已经适应生活在潮湿表面的细菌（比如说我们的脸）就会很快转移过来。
