Comedones are small, flesh-colored, white, or dark bumps that give skin a rough texture.
- The bumps are one type of acne.
- They are found at the opening of skin pores.
- A solid core can often be seen in middle of the small bump.
Comedones arise when cells lining sebaceous duct proliferate (cornification), and there is increased sebum production.
A comedo is formed by debris blocking the sebaceous duct and hair follicle.
It is now known that comedones also involve inflammation (see causes of acne).
