What happens to the puss in the pimples you don't pop?
gpt
Your body reabsorbs it. The pus contains the cells (phagocytes) that eat the intruding microbes or foreign material of some sort. The pus is kind of in a capsule to protect neighboring cells and tissue from further infection. So don't pop it.

Edit: Changes macrophages to phagocytes.
