An acne pustule is a type of pimple.
These bulging patches of skin are pores that have become clogged with
- pus,
- sebum (oil),
- cell debris.
They may also be called whiteheads, blemishes, and zits.
Though pustules can appear anywhere on body, they’re usually found on face, neck, shoulders, and back.
- A clogged pore is root cause of any pimple, including pustules.
- Oil, bacteria, or dead skin can block the pore.
- Pustules occur when walls of affected pore or pores begin to break down.
- As a result, pustules tend to be bigger than whiteheads and blackheads.
