We all have our own icky habits. But popping a zit is in a league of its own. The thing is, squeezing a pimple could have health consequences, and could potentially lead to infection and scarring.
So why do we keep popping them when we know we're not supposed to touch them?
Nicole Karcinski, a board-certified psychiatric and mental health nurse practitioner, explained in her blog on Racked that pimple-squeezing brings out the feel-good hormone, dopamine.
"Releasing dopamine is what's truly the neurobiological basis of the habit," wrote Nicole. "We do it, we feel good."
Dopamine strengthens that habit, she added, up to the point where we crave it even though we're aware that it's bad for us. It's the same reason people get hooked on illegal drugs.
However, in extreme cases, wantonly poking your pimples can be the result of obsessive compulsive tendencies.
According to Medical Daily, "dermatillomania" could be a root cause.
"Dermatillomania, also known as skin picking disorder, is a mental condition where individuals will repetitively pick at their own skin to the point of causing damage," the health website reported. "It's a form of obsessive compulsive disorder and included in the Diagnostic and Statistical Manual of Mental Disorders."
The lesson: If you think you suffer from the condition, see a doctor right away. Otherwise, you won't stop squeezing, introducing more scars to your beloved, handsome face.
