What is a pimple made out of?

Pimple pus is made from sebum (oil) that gets trapped in your pores, along with a combination of dead skin cells, debris (such as makeup), and bacteria. When you have inflammatory acne lesions (such as pustules, papules, nodules, and cysts), your immune system activates in this area, resulting in noticeable pus.

It is when oil gets trapped in your pores and the stuff that you put on your face such as makeup are dead skin, and then it formes a bump.
