Dr. Pimple Popper extracted a gigantic blackhead from a patient's forehead

• Dr. Sandra Lee — known as Dr. Pimple Popper — $4 on her YouTube channel.
• Her patient had a dilated pore of Winer, better known as a large black or whitehead.

On her YouTube channel, Dr. Pimple Popper recently $4 on a patient's temple while they chatted about books.

$4, better known as "Dr. Pimple Popper," dilated pores of Winer are large blackheads that get lodged in the openings of pores. This can lead to a build-up of sebum, oil, and dirt behind the blackhead.

"It's amazing what we grow," she told the patient as she squeezed sebum out of the dilated pore.

In the video, Lee began by squeezing the dirt and oil out of the opening after numbing the area. After squeezing as much out as she could, Lee used a tool to scrape out additional sebum from the dilated pore that she couldn't get out by pushing down.

Typically large dilated pores of Winer leave behind a sac under the surface of the skin that contains the excess dirt and oil. Lee used a scalpel to open up the pore and cut out the sack completely.

According to $4, getting rid of the entire blackhead — including the sac — ensures the pimple doesn't grow back.

After she was done purging sebum from the pore, Lee stitched up her patient and sent him on his way.
