时差N小时 人类为什么会长痘痘?(下)

That means there is nothing to open up the pore itself; and that means the pore is a great place for oils, dirt and bacteria to get clogged¹.

那就意味着没有什么措施可以打开毛孔，这就意味着毛孔会被油脂，污垢和细菌堵塞。

You can get zits anywhere vestigial follicles become clogged.

残留毛囊堵塞的地方就有可能长青春痘。

The big culprit on faces, though, isn't dirt so much as an internally-produced substance called sebum that makes the skin cells shed inside the pores.

不过脸上长痘痘的罪魁祸首与其说是尘垢，不如说是一种内部产生的皮脂，这种物质导致皮肤毛孔内的细胞脱落。

These dead cells, unable to flake² away, collect until they become an irritation³ to the pore.

这些死细胞，无法自动脱落，一直累积直到其对毛孔产生刺激作用。

At this point the body reacts in a miniature version of the way it deals with any other invasion: it sends white blood cells to the site to attack the invading body.

此时人体会减弱其他任何形式的入侵，从而它会将白细胞送至机体来抵抗受侵细胞。

The result is a mild inflammation at the scene of battle. That inflammation is the zit.

结果就会引发轻度的炎症。而那炎症就是青春痘。

So evolution, while having cleaned our hairy faces, gave us pimply⁴ skin instead.

可以这么说，进化在清理我们毛绒绒的面孔的同时，也会让我们的皮肤长出粉刺。
