Types of Acne
There are different types of acne lesions:
-
Comedones
-
Pustules
-
Papules
-
Cysts or nodules
COMEDONES
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
PAPULES
Papules are red inflamed bumps without pus
PUSTULES
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
Cystic acne
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
