These pesky black spots are a type of comedo, caused by open pores that become plugged with oil and dead skin cells that have turned black. Most people think this black gunk is dirt, but it actually has nothing to do with cleanliness. This combination of dead cells and oil turns black when it reacts to oxygen, a process called oxidation.

Whiteheads are another form of comedo, but in this case, the dead skin cells and oil are trapped underneath a thin layer of skin. Since air can’t enter the hair follicle, that gunk won’t oxidize, so it remains white. Aside from that, whiteheads are nearly identical to blackheads — they’re extremely common, can appear anywhere on the face and body, and can be treated with the right products.

Papules and pustules are blackheads and whiteheads that have become red and inflamed because they’ve been invaded by acne-causing bacteria, called p. Acnes. Papules are characterized as small, red, raised bumps that are typically painful. That pain is because bacteria has entered the area and caused an infection. Depending on the number of papules that are on your skin, papular acne can be classified as either mild, moderate, or severe.
