Advertisement To start, Lee numbed the silver dollar-sized bump at the end of Juan's eyebrow. Then she used a small surgical blade to create a small incision in the growth. Using scissors, she pried open the incision to reveal a pink bubble underneath. Though the growth looked like a cyst from the outside, Lee said she had to be extra careful because of Juan's genetic condition. After gently squeezing the growth, white pus squirted out and Dr. Pimple Popper was able to confirm it was a cyst, a growth known to create a thick substance when skin cells or oil get trapped under the skin.
