What Are The Different Types Of Acne?

Pustules

Acne pustules, which are larger than blackheads and whiteheads, contain yellow or white pus. A pustule tends to appear as a white bump that's hard to the touch, or as a red bump with a white center. It may be tender when an individual touches it. The skin surrounding the pustule may be inflamed or red, but this isn't always the case. Like other types of acne, pustules are caused by clogged pores. With a pustule, the walls of the clogged pore begin breaking down, leading to a larger pimple formation. Though folliculitis and acne are the most common causes of pustules, they can also be found in individuals who have certain kinds of eczema or psoriasis. The pus inside forms because the body is attempting to fight the infection caused by the bacteria or dirt inside the pore.
