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.
