What Are Acne Pustules?
Acne pustules are a type of pimple, or acne lesion. These small patches of bulging skin occur when your skin’s pores become clogged with pus, sebum (oil), and skin-cell debris. Commonly referred to as whiteheads, blemishes, and zits, acne pustules can appear virtually anywhere on the face and body, though they are most commonly found on the face, neck, shoulders, chest, and back. These pus-filled lesions can occur at any age, though they are especially common among teenagers and young adults undergoing hormonal changes, which often trigger acne breakouts.
Here, our dermatologist discusses the difference between acne pustules and other skin issues, why some individuals may have a higher likelihood of developing them, what medications might be available to you for treating them, and suggestions for how to help prevent breakouts in the future.

What Causes Pustules?
Pustules on face and body skin develop when the walls of an affected pore begin to break down, causing the pore to become a red and swollen skin lesion known as papular acne. As this occurs, white blood cells gather on the papule to try and combat infection as the pore breaks down. These white blood cells form the pus seen inside pustular acne blemishes. The papule results in a pustule filled with sebum, or skin oil, and bacteria (Propionibacterium acnes), and cell debris.
Acne can develop for different reasons, though typical triggers include changes in hormones during puberty, pregnancy, and menopause, oil and dirt building up in the skin, and certain types of medications. Acne may also have a genetic component, so family history can play a role.
What Do Pustules Look Like?
A pustular acne pimple appears different from other types of acne lesions and blemishes. Pustular acne is typically red, inflamed, and has a white head filled with yellow, white, or cream-colored pus that oozes out of the pimple if the pustule becomes broken open or pierced. In some cases, a whitehead pustule can feature a brown-colored dot at its center, which means debris is clogging that specific pore. Acne pustules usually occur near oil glands, particularly around the face, on the back, chest, and shoulders.
These lesions can vary in size from tiny to very large. Contrary to the features of non-inflamed acne lesions, such as blackheads, milia, and microcomedones, pustular acne is a form of inflammatory acne that can be tender to the touch or sensitive.

How Are Acne Pustules Diagnosed?
In most cases, acne pustules are easily diagnosed based on how the pimples present and appear, whether or not the patient has a personal or family history of acne, and other symptoms, such as lethargy or fever, commonly associated with viruses. The type of acne a patient has is categorized based on the size and spread of the pustules. Your dermatologist may grade your acne as a mild, moderate, or severe case of acne.
In addition to acne, other skin conditions, such as psoriasis, chickenpox, and insect bites, among other conditions, can likewise cause papules to develop on the skin. A pustule that grows to be incredibly large in size may be a boil, instead of an acne pustule. Your dermatologist can differentiate between acne pustules and pustules caused by another health or skin condition.
