I must confess, there is something so shameful that I do with my esthetician. I should be embarrassed and I know a lot of people will gross out when I tell them this. I send my esthetician tik-toks and Youtube videos of pimple toppings and blackhead removal videos.

Sometimes while I am getting a quick wax I stop her halfway to show her something on my phone. What were we watching? Pimple Popping videos of course.

Dr. Pimple Popper who has over 7 million subscribers on YouTube posts videos that many people can't quit. There is actually a scientific reason as to why you and I can't quit watching.

Dr. Heather Berlin is a Cognitive Neuroscientist and a professor of Psychiatry at the ICAHN School of Medicine at Mount Sinai in New York. Dr. Berlin explains "There’s a cycle of anxiety or arousal before the act and a sense of relief after,”

You get the perfect combo, the sense of calm, and sheer pleasure mentally and physically. When you see a pimple being popped you release dopamine which makes your brain activate your reward center.

Well, let your reward center have a "treat yo self" type of day and check out Dr. Sandra Lee's AKA Dr.Pimple Popper's most-watched videos on YouTube.
