Dermatologist Dr. Sandra Lee, also known as Dr. Acne Popper, has attracted more than three million YouTube subscribers with her acne videos. One of his latest videos, posted on Monday, shows a glandular cyst on a woman’s head.

Thanks to Lee’s surgical experience and painkillers, removal is quick and satisfactory. Around 1:48 a.m., a stream of dirt shoots out from the cyst; At 2:30 p.m., Lee laughs that it’s just a lamp.

During the procedure, Lee had an interesting conversation with a patient who told him that he had once tried to open a cyst at home. The woman said that she squeezed the cyst and after a few days noticed that “something” came out – the growth did not completely disappear.

This anecdote reminds us that removing a cyst on your own is often useless and dangerous.

According to DermNet NZ, the educational website of the New Zealand Dermatology Association, glandular cysts are common benign tumors of the scalp. These cysts are sacs of skin filled with keratin, the protein that makes up hair and nails, and a caustic substance that is released when the cyst is squeezed.
