Comedones

Comedones are small, flesh-colored, white, or dark bumps that give skin a rough texture. The bumps are caused by acne. They are found at the opening of skin pores. A solid core can often be seen in the middle of the small bump. Open comedones are blackheads and closed comedones are whiteheads.
