Dr. Pimple Popper removed 5 cysts from a man's scalp and the insides looked like scallops

• Dr. Pimple Popper removed five pilar cysts from one man's scalp in one sitting.
• The celebrity dermatologist was able to pull out each cyst easily with tweezers.
• Pilar cysts usually grow on the scalp and are filled with clogged skin cell protein called keratin.

On Friday, dermatologist Dr. Sandra Lee shared a cyst-popping marathon, where she removed five growths from one man's scalp in under 20 minutes.

In the May 7 video, Lee, who is also known as Dr. Pimple Popper, showed how she removed the various pilar cysts.

Pilar cysts are the most common type of cyst, and usually develop on the scalp, according to the National Institutes of Health (NIH). Less than 10% of the population gets pilar cysts and they typically aren't cancerous.

Pilar cysts form when they fill with keratin, a protein found in skin cells, Insider previously reported.

In Dr. Pimple Popper's most recent video, the cysts resembled tiny scallops when she yanked them from incisions she made in the man's scalp.

To treat the man in the video, Dr. Pimple Popper used a scalpel to create a two-inch incision on top of one of the cysts. Though she didn't show it on camera, the celebrity dermatologist injects a numbing solution around each growth before treating a patient.

Then she used her scissors to deepen and widen the incision, and plunged tweezers inside the hole. After some poking around, Lee was able to grab the entire cyst and pull into out all at once. Before closing the incision with stitches, Dr. Pimple Popper used her scissors to remove a thin sac that held the cyst in place.

The second pilar cyst was triple the size of the first one, but Lee used the same procedure as before to loosen the white and bulbous mass. Once Dr. Pimple Popper removed it, she said it looked like a plum.

She repeated the process three more times to remove the final pilar cysts.

Afterwards, she gave viewers and her patient a cyst show-and-tell, laying all of the cysts side-by-side on a nearby table.
