Life
Of all the bizarre elements of human psychology exposed to the world by the invention of the internet, the rise of the pimple-popping video has to be one of the most bizarre — and amazing. Dermatologist Dr. Sandra Lee, otherwise known as "Dr. Pimple Popper," is one of Youtube's breakout stars thanks to her clips of pimples, cysts, blackheads and other skin nasties that she prods, pokes, and clears with plastic gloves and professional devices. Her most popular videos have views into the millions, and she's only one of a cluster of pimple popping media available. Why in the world are we so fascinated by pimple popping videos? As with most things, science has an answer.
The psychology behind the popularity of pimple-popping spectacles is more complex than it seems, and there isn't one definitive explanation that rationalizes the entire experience. Our fascination with watching the pus explosions of others seems to be due to a combination of neural dopamine and tension release, the lure of the forbidden, cultural ideas of disgust, and socially evolved concepts of grooming and intimacy. Surprisingly, scientists have proved rather reluctant to study the legions of pimple popping fans in detail, so all of these ideas remain hypothetical. (Maybe they're simply too busy watching Dr. Lee's videos themselves — and getting one of her pimple-popping surgical devices, which are available for purchase, to take home.)
We Love Gross Stuff
The human fascination with the visuals of disgust at play in pimple-popping videos seems to defy psychology. Disgust is hardwired into the human brain; our "eww" response is a behavior designed to stop us getting sick or encountering danger by making us avoid potentially upsetting substances and areas. Given that, you'd think that pus and the other materials inside a 25-year-old zit would turn us off. For many people, that is indeed the case, but for legions of fans of pimple popping videos, the release of seeing a built-up pore finally cleaned out is worth every second.
Historians of disgust point out that our definition of "disgusting" changes with our culture; as standards of hygiene and behavior shift, so does our degree of repugnance. Some of our pimple-popping fascination in the modern world may come from the fact that it's no longer perceived as greatly disgusting, but part of it may also come from our excitement and titillation at seeing something controversial, intimate and forbidden.
We Love Grooming
When it comes to our approach to pimple-popping itself, onscreen or off, psychological approaches drawn from primates may suggest another explanation. Among many primate species, grooming — picking through the hair and skin of others, combing, finding insects, and generally managing one another's appearance — serves a social function. It's hygienic, but it also bonds primate groups together, reinforces social hierarchies, and helps conflict resolution and communication.
Some theorists believe that grooming behaviors among humans, including zit-popping between partners, families and friends (yes, all those videos also exist), continue to serve that function. It might serve the same purpose that brushing a child's hair or doing a friend's make-up does: expressing bonds and intimacy. It's possible that audiences of pimple-popping videos feel an ancient sense of closeness with the person they're watching, though, again, this hasn't been explored by scientists specifically.
Amid all these explanations, there's no real sense that watching a pimple popping video or ten is unhealthy or psychologically problematic. If you're developing a fixation with them, though, or are motivated to pick your own skin to excess by viewing them, they may be a trigger for compulsive behavior, and you should consider seeing a professional therapist. No, not Dr. Lee.
