Pustules, otherwise known as pimples

Pimples are tender, larger bumps that have a circular center. The center is filled with yellowish/whitish pus over a red skin base. In fact, they look a lot like larger whiteheads but inflamed.
Causes:
- Allergic reaction most commonly to food, or environmental allergens
- Insect bites (poisonous)
- When the skin gets clogged with dead skin cells and oil
Nodules

The inflamed, painful, and hard lumps that are located deep in the skin are known as nodules. This type can become severe and may cause skin complications like scarring and dark spots.
Causes: These are considered inflammatory acne and are formed when clogged pores damage the cells and tissue deep beneath the surface of the skin.
Cysts

When pustules become infected they start to become painful. This is when pustules become a cyst. Cystic acne consists of white or red, painful, large, and yet soft lumps that are located deep in the skin — even deeper then nodules. They are also filled with pus. In fact, these are considered to cause severe skin complications like scarring.
Cause: infected pustules
