【英语时差8,16】青春痘Vs毛茸脸（上）

（单词翻译）

One of the least pleasant things about being human is the appearance at adolescence¹ of pimples². Not only do they make their entrance just at the time when people are most self-conscious, but they come and go for the rest of your life. It would almost be better to have a hairy face. Ironically, the general covering of our bodies in hair — what we call “fur” on other animals — is at the root of our problem with acne. In the course of evolution human beings lost their entirely³ hairy faces and now have a lot of exposed skin there: even a bearded man with bushy eyebrows⁴ has much of his face bare. The structures in the facial skin that once gave rise to hair, however, have not disappeared entirely: many still contain tiny vestigial hairs which do not grow. That means there is nothing to open up the pore⁵ itself; and that means the pore is a great place for oils, dirt and bacteria to get clogged⁶. You can get zits anywhere vestigial follicles become clogged.
