• In a new Instagram video, Dr. Pimple Popper pops a 20-year-old forehead cyst filled with goopy vanilla yogurt.
  • In the clip, the patient doesn't even realize Dr. Lee made an incision, let alone removed the entire cyst, until the procedure is over.
  • This type of cyst is called a steatocystoma, which is a small, benign lump filled with a yellowish, oily substance called sebum.

In a new Instagram video, Dr. Pimple Popper aka, dermatologist and TLC host Dr. Sandra Lee, MD pops a 20-year-old forehead cyst filled with goopy "vanilla yogurt." This one is extra disturbing, so buckle up.

To begin the clip, Dr. Lee makes an incision into the forehead bump. Immediately, the buttery contents spills out, ready to evacuate its 20-year-old home. Dr. Lee squeezes the growth, forcing out more gooey gunk.

A vanilla Go-Gurt steatocystoma, one fan commented on the clip. Trust me, you'll see the resemblance.

To complete the removal, the famed dermatologist goes in for the cysts sac. Removing this membrane virtually guarantees the growth will be gone for good.

When Dr. Lee tells the patient that she just removed the sac, he replies, Oh, its open already? Yes, these removals, which are done under local anesthesia, are that easyno matter how gruesome they look.

Steatocystomas are typically small, benign lumps that are filled with sebum. Sebum is a yellowish, oily substance that helps lubricate the hair, skin, and nails, according to the National Institute of Health .
