Pustules are a type of inflamed acne lesion that contain pus, a yellowish liquid that’s made up of bacteria and dead white blood cells.Â
If you’re prone to acne breakouts, you may have noticed pustules forming next to other common types of acne. Pustules can vary in size and commonly referred to as zits, pimples and a variety of other terms.
Since pustules tend to be larger and more visible than other types of acne, such as whiteheads and blackheads, dealing with them can be a major annoyance. They often form in highly visible parts of the face and body, making them hard to cover up with clothing or makeup.
Luckily, like other forms of acne, pustules are highly treatable. Below, we’ve what pustular acne is and how pustules typically develop. We’ve also explained the treatments that are available to get rid of pustular acne lesions and prevent them from coming back.
Although many people think of all acne lesions as zits, pimples, blemishes or similar, the reality is that there are several different types of acne.Â
Some acne lesions are referred to as comedones. Comedones are a non-inflammatory type of acne, meaning they typically aren’t red, raised or painful. Whitehead and blackheads — two of the most common types of acne — are both types of comedonal acne.
Certain other acne lesions are referred to as inflammatory acne. This is the acne category that pustules belong to. Pustules begin as comedonal acne but become inflamed due to the growth of bacteria inside the acne lesion.
Acne pustules look like small, red bumps. They often have a small, white or yellow-colored dot at their center that’s caused by the presence of pus inside the lesion.
To understand how acne pustules form, it’s important to cover the basics of how and why acne breakouts occur.
Acne develops when the hair follicles in your skin, commonly known as pores, become clogged with a combination of sebum and dead skin cells.
If you’ve ever wiped down your face at the end of the day, you’ve no doubt noticed that the skin around your nose, forehead and other parts of your face can get quite oily. This oil is referred to as sebum — a natural oil that’s secreted from the sebaceous glands inside your skin.
Sebum plays a key role in keeping your skin lubricated and healthy. It also helps protect your skin from damage due to friction, bacteria and sun exposure. Research even shows that sebum helps your body to repair scratches, cuts and other wounds that affect your skin.
When your sebaceous glands produce too much sebum, it can clog inside your pores and lead to blockages. In some cases, dead skin cells can also build up in your pores, causing them to become blocked. When a pore becomes blocked, an acne lesion develops.Â
Not all acne lesions turn into pustules. A lot of the time, a blocked pore develops into a type of comedonal acne, such as a whitehead or blackhead.
Pustules develop when bacteria gets stuck inside pores that are blocked by sebum, dead skin cells or a combination of the two. As the bacteria multiply inside the blocked pore, it becomes red, inflamed and often painful.Â
Like other types of acne, pustules can vary in size from small to quite large. They tend to look like a red, swollen bump with a white center.Â
Pustules can develop in many parts of your body. In addition to your face, you may develop pustules on your:
