WATCH | This doctors pop's people's zits, films it and posts it on social media. People love it.
If you go to YouTube, you'll find hundreds of videos of pimples being popped with millions of views. Chances are most of those videos belong to Dr. Sandra Lee, a dermatologist in Upland, California.
Dr. Lee, or "Dr. Pimple Popper," as she's known in social media circles, posts videos of herself popping pimples, blackheads, cysts and even lipomas (fatty harmless lumps).
And they're a hit. She has more than one million YouTube subscribers and two million Instagram followers.
Dr. Lee numbs the skin of a patient. She has two assistants in the room. One is posting videos to Snapchat the other is capturing it all on camera.
Why she started doing it
Two years ago, Dr. Lee started posting videos of herself popping pimples, when someone told her she should check out Reddit.
"I noticed there was a whole community of people who liked these popping videos," said Dr. Lee.
"And there was. There was (and is) a whole section dedicated to 'popping' videos and images."
Now she posts at least three videos a week.
Go to Dr. Pimple Popper's YouTube channel, and you'll find all types of pops.
People love the videos
"This is the most relaxing and beautiful thing I've ever seen." That's what one of the comments on her YouTube channel's latest blackhead video said.
"My favorites are the really juicy ones," said Michellene Nguyen, a self-proclaimed "popaholic."
"I watch them before going to bed. It kind of helps me sleep at night," said Jennifer Le, Michelle's friend who was visiting Dr. Lee for a procedure during Circa's visit to her practice.
Why are people so drawn to these videos?"I think it's relaxing for a lot of people," said Dr. Lee. "I think there's some kind of cleansing feeling that a lot of people have."
A psychology professor at the Illinois Institute of Technology said there might be a method to the madness.
"Everyone has, at some point in their life, fiddled with a pimple on their face," said Gregory Chasson, a psychology professor at the Illinois Institute of Technology.
"And even if they don't have that extreme phase, they tend to connect with that sensation or that experience and a lot of times, the sense of relief that comes with picking," Chasson added.
Why she posts the videos now
Today, Dr. Lee has a team in Los Angeles that edits her videos and designs merchandise for her Dr. Pimple Popper store.
"This is free advertising. And you can generate some revenue."
But she doesn't just do it for the money. She also has a Dr. Pimple Popper University YouTube channel that's aimed at dermatology students and anyone interested in the science behind it all.
