How Exactly Are Spots/Pimples Formed?

Question

I want to know exactly how they are formed and why they spread if you pop them...

Also why is there pus in them? (sorry sounds gross)

And if you leave them and don't touch them why do they go away?

I know the basic answers to these questions i just want some in depth ones, Thanks! =)

Answer 1

through like dirt  getting in your pauses and when you body fighting stuff or somthing lol.

Answer 2

there are 3 differant types of spots im not sure how to describe it but i remember reading it in a magazine before. it basicly is when dirt blocks your pores and the natural oil your skin produces to keep it from drying out, builds up. as far as i no pooping them doesnt spread them but they cant get big red and sore. dont try too hard to pop the spot. like if it doesnt pop easily dont force it other wise youl push the dirt and oil deeper into the pore meaning youl prob end up with a second head.

hope this helps
