What Is Inside A Pimple When You Pop It?

Have you ever wondered what exactly is inside a pimple when you can’t resist the urge to pop it? We’ve all been there, facing those pesky bumps on our skin that seem to appear at the most inconvenient times. But have you ever stopped to think about what’s actually going on beneath the surface? When you finally succumb to the temptation and squeeze that pimple, what do you find lurking inside? Let’s explore the fascinating world of pimple-popping and discover what lies beneath!


Pimples. We’ve all dealt with them at some point in our lives, and we all know how frustrating and uncomfortable they can be. But have you ever wondered what actually lurks beneath the surface of a pimple? What causes them to form, and what happens when you pop them? In this comprehensive article, we’ll dive into the anatomy of a pimple, explore the stages it goes through, delve into its contents, discuss the risks of popping, and learn how to properly treat and prevent them. So, let’s uncover the secrets of pimples together!

The Anatomy of a Pimple

Hair follicles and sebaceous glands

To understand the anatomy of a pimple, we must first understand the role of hair follicles and sebaceous glands. Our skin is covered in tiny hair follicles, and each follicle has a sebaceous gland attached to it. These sebaceous glands produce an oily substance called sebum, which helps lubricate and protect the skin.

Sebum production

Sebum production is a normal process that keeps our skin moisturized. However, when the sebaceous glands produce an excess of sebum, it can mix with dead skin cells and clog up the hair follicles, leading to the formation of a pimple.

Dead skin cells

Throughout our lives, our skin naturally sheds dead skin cells, which should be sloughed away. However, when these dead skin cells become trapped in a hair follicle blocked by excess sebum, they can accumulate and contribute to the development of a pimple.

While our skin is inhabited by countless bacteria, one particular bacterium called Propionibacterium acnes (P. acnes) plays a significant role in the formation of pimples. When a hair follicle becomes clogged with excess sebum and dead skin cells, it creates an ideal environment for the growth of P. acnes. The bacteria feed on the excess sebum, leading to inflammation and the characteristic redness and swelling of a pimple.

The Stages of a Pimple


The first stage of a pimple is its formation. As mentioned earlier, when excess sebum and dead skin cells clog a hair follicle and create an environment conducive to bacterial growth, a pimple begins to develop. At this stage, you may notice a small bump or a red spot on your skin, indicating the early formation of a pimple.


As the bacteria thrive in the clogged hair follicle, the immune system responds by releasing white blood cells to fight the infection. This immune response leads to inflammation, causing the pimple to become more swollen, red, and painful. The blemish may increase in size at this stage, making it more noticeable and uncomfortable.

Pus formation

As the immune system continues to fight the bacterial infection, pus may begin to form within the pimple. Pus is a mixture of dead white blood cells, bacteria, and cellular debris. It appears as a yellowish or whitish fluid and is a sign that the body is actively trying to eliminate the infection.


Finally, in the last stage of a pimple, it may either extrude or resolve on its own. When a pimple extrudes, it means that the accumulated pus and other contents are expelled from the hair follicle, either with gentle pressure or spontaneously. This can lead to temporary relief and a visible reduction in redness and swelling.

The Contents of a Pimple


One of the primary contents of a pimple is sebum, the oily substance that normally moisturizes our skin. When the sebaceous glands produce an excess amount, it becomes trapped within the hair follicle and contributes to the development of a pimple.


Pus is a vital component of a pimple, indicating an active immune response to fight the invading bacteria. It is composed of dead white blood cells, bacteria, and other cellular debris. When a pimple becomes filled with pus, it is a sign that the body is actively trying to eliminate the infection.


In some cases, a pimple may rupture or be agitated during popping, causing a small amount of blood to be present. This bleeding occurs when tiny blood vessels in the area are damaged. While blood is not a typical component of a pimple, it may be seen after improper popping or manipulation.

Dead skin cells

Dead skin cells that accumulate within a clogged hair follicle contribute to the formation of a pimple. These cells mix with excess sebum, bacteria, and other debris, creating a fertile breeding ground for bacteria and inflammation. Removing dead skin cells through proper exfoliation can help prevent the formation of pimples.

What Happens When You Pop a Pimple?

Risk of infection

When you pop a pimple, you risk introducing additional bacteria into an open wound. Popping can cause the pimple to burst, allowing bacteria and other contaminants from your fingers or surrounding skin to enter the area. This can lead to infection and potentially worsen the condition of your skin.

Scar formation

Popping a pimple can also increase your risk of scarring. The act of squeezing or forcefully extracting the contents of a pimple can damage the surrounding tissue and lead to the formation of scars. These scars may be temporary or permanent, depending on the severity of the damage caused.

Spreading the infection

Popping a pimple can spread the infection to adjacent areas of the skin. When you apply pressure to a pimple, you force its contents to move outward, potentially infecting nearby follicles. This can result in the formation of new pimples in the surrounding area, exacerbating the problem and prolonging the healing process.

Delayed healing

Popping a pimple may also delay the healing process. The act of manipulation, coupled with the introduction of foreign bacteria, can disrupt the body’s natural healing mechanisms. This can lead to increased inflammation, prolonged redness, and a more extended recovery time.

How to Properly Treat a Pimple

Washing the affected area

Properly treating a pimple starts with good hygiene. Wash the affected area gently with a mild cleanser and warm water twice a day. Avoid harsh scrubbing or using abrasive products, as this can further irritate the skin and potentially worsen the condition.

Applying topical treatments

There are various topical treatments available over-the-counter that can help reduce inflammation and promote healing. Look for products containing ingredients like benzoyl peroxide, salicylic acid, or tea tree oil. These can help kill bacteria, exfoliate the skin, and control excess sebum production.

Avoiding picking or popping

One of the most crucial steps in treating a pimple is to resist the urge to pick or pop it. Instead, allow the pimple to run its course naturally. Picking or popping can introduce bacteria into the area, increase the risk of infection, and potentially lead to scarring.

Seeking professional help

If your pimples persist or are severe, it may be beneficial to seek professional help from a dermatologist. They can provide personalized treatment options, such as prescription medications or in-office procedures, to help alleviate your acne and prevent further breakouts.

When to Seek Medical Attention

Persistent or severe acne

If your acne persists despite proper care and over-the-counter treatments, it may be time to consult a dermatologist. They can evaluate the severity of your condition and provide additional treatment options to address your specific needs.

Signs of infection

If you notice increasing redness, warmth, tenderness, or discharge from a pimple, it may be a sign of an infected pimple. In such cases, it is crucial to seek medical attention promptly to prevent the infection from spreading and causing further complications.

Cysts or nodules

Cysts and nodules are more severe forms of acne characterized by large, deep, painful lesions beneath the skin’s surface. If you develop cysts or nodules, it is essential to consult a dermatologist for appropriate treatment as these types of acne can lead to scarring and long-term skin damage if left untreated.

Preventing Pimples

Maintaining good hygiene

Maintaining good hygiene is essential in preventing pimples. Wash your face twice a day with a gentle cleanser, and avoid touching your face with unwashed hands. Cleanse your makeup brushes regularly and avoid sharing personal items that come in contact with your face to minimize bacterial transfer.

Using non-comedogenic products

When selecting skincare and cosmetic products, opt for non-comedogenic options. Non-comedogenic products are formulated to not clog the pores, helping prevent the development of pimples. Look for products labeled as non-comedogenic or oil-free to maintain clear and healthy skin.

Avoiding excessive oil and sweat

Excessive oil and sweat can contribute to the clogging of hair follicles and the formation of pimples. To prevent this, cleanse your skin after sweating and avoid using heavy or greasy skincare products that can exacerbate the problem. Use oil-absorbing sheets or powders throughout the day to keep your skin fresh and matte.

Eating a balanced diet

Although diet alone may not be the sole cause of pimples, eating a balanced diet can promote overall skin health. Incorporate plenty of fruits and vegetables into your meals, limit your intake of sugary and greasy foods, and drink an adequate amount of water to keep your skin hydrated from within.


Pimples may be stubborn and frustrating, but understanding their anatomy and how to properly treat and prevent them can help alleviate the discomfort they cause. Knowing that pimples form as a result of clogged hair follicles, excess sebum, dead skin cells, and bacterial growth allows us to make informed decisions in our skincare routine. Remember, popping pimples can lead to infection, scarring, and delayed healing, so it’s best to resist the temptation and opt for appropriate treatments instead. If acne persists or is severe, seeking medical attention is crucial. By maintaining good hygiene, using non-comedogenic products, avoiding excessive oil and sweat, and nourishing our bodies with a balanced diet, we can take proactive steps to prevent the formation of pesky pimples and enjoy clear, healthy skin.
