Humans are pimply. It's part of what sets us apart from the rest of the animal kingdom. While it's true that some form of acne vulgaris affects other species—it's been found in some Mexican hairless dogs and induced experimentally in rhino mice—acne is largely an affliction of our accursed species alone. (Somewhere between 85 and 100 percent of adolescents exhibit acne—and a significant minority of adults, too.) Why is the human animal so peculiar in its tendency to form volcanic comedones, papules, pustules, nodular abscesses, and, in some severe cases, lasting scars? According to evolutionary theorists Stephen Kellett and Paul Gilbert, we probably owe these unsavory blemishes to our having lost our apish pelts too rapidly for our own good.
Although increasingly glaborous (hairless) skin evolved for adaptive purposes—it may have enabled our ancestors to keep cool, for example, while traveling across the hot savanna—the sure-footed pace at which genes for depilated flesh were selected posed some cosmetic problems. Kellett and Gilbert observe that the evolution of our sebaceous glands, which were accustomed to dealing with hair-covered flesh, lagged behind this change in our appearance. As a consequence, all that oily and waxy sebum, normally committed to lubricating fur, hadn't much fur to lubricate. So the sebum started to build up and clog our pores instead. (There are many issues that a person suffering from hypertrichosis—also known as "werewolf syndrome"—has to worry about, but acne tends not to be one of them.) Better this evolutionary account than pimples by intelligent design, in any event. What a heartless God indeed that would wind up the clock so that our sebaceous glands might overindulge in sebum production precisely at that time in human development when we'd become most acutely aware of our appearance.
It only makes matters worse that evolution has given us another distinctly human trait, and one that makes any outbreak of acne infinitely more upsetting. I'm referring, of course, to our crippling sensitivity to other minds. Although this statement is not without some controversy, it seems likely that other species do not share our fine-tuned facility at taking on the rich psychological perspective of others. (As I've mentioned elsewhere, humans are natural psychologists endowed with a "theory of mind.") If this is so, then seeing the flash of disgust, or even a more innocent curiosity, reflected in other human eyes whenever they steal away to our physical flaws, triggers in us an aversive state entirely original to our species. Anyone who ever has had a ripe, loathsome pimple placed strategically upon the tip of their nose by the epidermal fates has felt this painful interpersonal state.
Consider a scene from Jean-Paul Sartre's No Exit, in which three strangers come to realize that they've just been cast to Hell, which is, strangely enough, an average, furnished drawing room. The Devil's insidious rub, however, is that there are no windows, no mirrors, and no sleep permitted in this room. Even the characters' eyelids are paralyzed, disallowing them the simple luxury of blinking. Their exquisite little torture is for all eternity to be under one another's unrelenting glare. Inez, a sadistic lesbian, knows just how to push the buttons of the other female in the room. "What's that?" she asks, examining Estelle's face. "That nasty red spot at the bottom of your cheek. A pimple?"
"A pimple?" replies frantic, mirror-deprived, pampered debutante, Estelle. "Oh, how simply foul!"
Sartre's chthonic allegory bears a striking resemblance, in fact, to the sort of living hell that many acne sufferers report experiencing on an everyday basis. For a 2005 report in the British Journal of Health Psychology, for instance, psychologists Craig Murray and Katherine Rhodes interviewed, via email, around a dozen members of an online acne support group, who'd been prescribed antibiotics or hormone treatments for their condition and suffered from acne for at least a full year. "Michelle" eloquently describes what it feels like to meet someone new, face-to-face:
I can feel the self-consciousness slowly consume me as the conversation progresses. Eventually I cannot even retain my train of thought and become tongue-tied. I unravel. I do become overwhelmed at what others might be thinking—I don't usually assume what they might be thinking with any specificity. That would be too painful an endeavour. But I do give them a generalized voice. I acknowledge to myself that they have seen the acne and most likely think less of me due to its presence.
Another woman, "Laura," emails:
When I'm talking to people, I always stare them straight in the eye to watch if their pupils wander to other places on my face where I have a zit. And they usually do.
Speaking of thinking about others' thoughts, I know what you're thinking: Those who'd judge a book by its cover or ostracize a poor, pimpled pal in these ways ought to be scorned in public themselves. I very much agree. But in spite of our sympathy—perhaps empathy—for those suffering from such visible skin disorders, even the most kind-hearted among us appear to associate acne sufferers with undesirable characteristics. At least, these were the results reported by University of Sheffield psychologist Tracey Grandfield and her colleagues in a 2005 issue of the Journal of Health Psychology. Using a variation of the Implicit Association Test—an empirical measure used to get at people's unconscious attitudes and beliefs—the authors found that, compared with our ratings of clear-skinned individuals, we're quick to associate unpleasant concepts (brutal, bad, ugly, angry, aggressive, vomit, mean) with acne sufferers.
