Types of Acne

There are different types of acne lesions:

• Comedones

• Pustules

• Papules

• Cysts or nodules

Comedones can be open (blackheads) or closed (whiteheads). Blackheads occur when hair follicles are partially blocked by sebum-oil, bacteria and dead skin cells. The dark color is not dirt, but because the sebum oxidizes and takes on a black color. Whiteheads occur when pores are completely blocked

Pustules, often called "pimples" or "zits", are inflamed lesions that occur as the result of clogged pores.  They have a collection of pus consisting of white blood cells and the bacteria they are fighting

​

Papules are red inflamed bumps without pus

Cystic acne, or acne nodules, characterize a more severe form of acne and appear as large, painful bumps under the skin’s surface.  These frequently cause acne scarring
